Best Electric Bike Helena MT: 3,706 Blocks Graded

The best electric bike Helena MT riders can buy depends on which half of the city they live in. Helena is two cities stacked against each other. East of Last Chance Gulch the valley floor runs almost flat for miles; west of it the ground stands up and does not sit down again until Mount Helena.

We measured all of it, every street block inside the city limits, at one-meter resolution, and then measured what that ground does to riders of different weights, on bikes of different weights, in a place with 169.9 freezing nights a year.

The answer is not one bike. It is six answers, and which one is yours depends on your side of town, your body, your building and your calendar.

Quick Answer. Buy a 20 mph two-wheel e-bike: Montana law makes that a bicycle, which is what opens the Centennial Trail to you under power. West of Last Chance Gulch, buy torque — the Eunorau FAT-AWD 2.0 at $1,699. On the valley floor, the META275 1.0 at $1,399. Upstairs, the 61.7 lb META24.

Anything faster than 20 mph, and any three-wheeler, is a moped here: legal on every street, motor off on the path. That single line decides more Helena purchases than any spec on the bike.

What this guide covers

This guide is organized around one legal fact and six ways of riding. The law comes first because in Montana it decides where you may ride before it decides anything else, then the measured city, then the six areas with the bikes that suit each.

• Montana's 170-pound e-bike test, and why there are no classes here
• The city measured — every block, every district, every neighborhood name
• What the hill costs you, by rider weight and fitness
• The winter, in freezing nights and snow-lying days
• The stairs, and the 51-pound benchmark
• The six areas: hills · valley floor · winter · the walk-up · three wheels · cargo
• Range on the hills, as a ratio every bike shares
• The seventeen picks side by side
• Where you may actually ride · Where the bike network is · What it costs against driving
• Every neighborhood, 183 names with their own grades
• Honest ledger · FAQ · Limitations

What we measured, and how

Every figure on this page comes from a named public dataset, recomputed rather than quoted.

Street grades are measured on the U.S. Geological Survey's 1-meter bare-earth lidar for Helena, 3DEP project MT_Statewide_Phase4_B22, published November 14, 2024, taking 97,478 elevation samples every five meters along 3,715 blocks. The chain was checked against the USGS Elevation Point Query Service at 34 separate blocks. Thirty-four agreed, none disagreed, and the worst single-point disagreement was 0.40 meters.

Neighborhood boundaries are the City of Helena's own seven Citizens Council districts. Climate figures are NOAA's 1991–2020 normals for the station inside the city. Bike weights, payload ceilings, rider-height ranges and torque are each read from the manufacturer's own page and dated. Where a maker publishes nothing, the cell is empty and no advice rests on it.

Montana writes its e-bike law around a 170-pound rider

Start with the law, because in Montana it decides where you may ride before it decides anything else — and because Montana's law does not look like anyone else's.

Look for a class on your Montana e-bike and you will not find one. The three-class vocabulary that forty-two states run on is simply absent here — not from the definitions, and not from the heading of any of the 1,222 sections of Title 61. The Montana Department of Transportation's own bicycle page sends you to a single part of the code, and that part is the whole of it.

"Electrically assisted bicycle" means a vehicle on which a person may ride that has two tandem wheels and an electric motor capable of propelling the vehicle and a rider who weighs 170 pounds no faster than 20 miles an hour on a paved, level surface. — MCA § 61-8-102(7)

Read that again, because it is unusual enough to be worth it. Montana's e-bike test is written in terms of a rider's body weight. The statute picks a 170-pound rider, puts them on the bike, and asks whether the motor alone can push them past 20 mph on flat pavement. If it cannot, the machine is an electrically assisted bicycle — and § 61-8-102(2) then says that a "bicycle" "includes an electrically assisted bicycle."

Being a bicycle is the whole prize. A bicycle may use any roadway or paved shoulder under § 61-8-605. And under § 61-8-608, a bicycle may be ridden on a sidewalk or a bicycle path under power. That section restricts only mopeds and motorized scooters, which "may be operated on and along a sidewalk or a bicycle path only under human propulsion."

The limiter is the law here, so leave it alone

One consequence of a statute written around what a motor is capable of rather than what it is set to: the setting matters.

Several makers in this guide publish their 20 mph cap as adjustable. Eunorau prints "Class 2, speed limited, unlockable" on its specification tables; Qiolor states that "the default maximum speed is set to 20 MPH, which can be adjusted according to user preferences"; Eunorau's FLASH LITE 2.0 lists pedal assist as "Class 1~4, Default Class 2."

Raise that limit and the bike stops being an electrically assisted bicycle in Montana. It becomes a moped, and § 61-8-608(3)(b) then bars it from a sidewalk or a bicycle path under power.

Leave the limiter at 20 mph and the Centennial Trail is open to you. Unlock it and it is not. Nothing about the bike changes; the category does — and § 61-8-601(1) makes it a misdemeanor to do any act forbidden in this part.

What happens when the bike is faster, or has three wheels

Two kinds of machine fall outside that definition, and both land in the same place.

A bike whose motor will push a 170-pound rider past 20 mph is not an electrically assisted bicycle.

A three-wheeler is a harder question, and the statute cuts both ways. Section 61-8-102(2) defines a bicycle as human-powered "irrespective of the number of wheels," so wheel count is expressly irrelevant to being a bicycle.

What a trike cannot satisfy is the electrically assisted definition at (7), which requires "two tandem wheels." An electric trike is not human-powered enough for (2), and not two-wheeled enough for (7). It falls out between them.

Both then have to be tested against the moped definition at § 61-8-102(14), and it has four limbs, not one: "two or three wheels, foot pedals to permit muscular propulsion, and an independent power source providing a maximum of 2 brake horsepower," which also "may not be capable of propelling the device, unassisted, at a speed exceeding 30 miles an hour on a level surface."

A pedal-equipped e-bike or e-trike under about 1,500 watts and under 30 mph meets all four limbs. A machine that fails one — no pedals, or a motor that will run past 30 mph — is not a moped either.

At that point it is a motor vehicle, with the registration and license that go with one. Every bike on this page has pedals and a 20 mph published cap, so none of them is near that line.

Becoming a moped in Montana is milder than it sounds. A moped is expressly not a motor vehicle — § 61-1-101(41)(b) excludes "a bicycle, a motorized scooter, or a moped as defined in 61-8-102" — and it is not a motorcycle either.

Registration under § 61-3-301 attaches to motor vehicles, and the driver's license requirement in § 61-5-102 attaches to driving a motor vehicle. Neither reaches a moped. No plate, no license.

What changes is the path. § 61-8-608(3)(b) lets a moped onto a sidewalk or a bicycle path only under human propulsion — pedaling, motor off. In a city whose flat spine is a shared-use trail, that is the difference that decides a purchase.

This matters most to the readers least likely to expect it. An electric trike is the obvious answer for a rider who wants stability, and Helena's own search traffic asks for trikes constantly. In Montana that trike is a moped, and the Centennial Trail is a pedal-only proposition on it.

A caveat worth stating plainly: this is the plain reading of the statutory text. We located no Montana appellate decision and no Attorney General opinion applying that wording to an electric trike, so it is published as a reading of the code and not as settled law.

No helmet law, no minimum age

No helmet is required of any rider in Montana, at any age, on any bicycle. Worth checking rather than assuming, and it holds across every one of the 1,222 sections of Title 61.

The only headgear provision in the title is § 61-9-417, "Headgear required for minor motorcycle riders," and a bicycle is not a motorcycle under § 61-1-101(43)(e).

Two honest limits on that. A heading sweep is a strong check rather than a perfect one, and it checks state law only — a city may set its own rule.

There is likewise no minimum age to ride a bicycle in Montana, and an electrically assisted bicycle is a bicycle. Wear a helmet anyway, and the age question for a family is a fit question — standover height, reach and weight — not a legal one.

The code is current. § 61-8-102 was amended twice in 2025 — Chapter 23 and Chapter 693 — and § 61-8-605 by Chapter 23, with § 61-8-608 amended by Chapter 693.

The 170-pound sentence survived that session unchanged. Two 2023 bills, House Bill 261 and Senate Bill 342, would have redefined e-bikes as non-motorized. Neither carries a session law chapter number in the Legislature's own bill archive, and neither became law.

Best electric bike Helena MT: the ground it has to climb, in seven districts and 3,706 blocks

Helena governs itself through seven Helena Citizens Council districts, and they are the right unit for this because they tile the city. The seven polygons compute to 17.355 square miles against the city-limits boundary's 17.373 — they cover 99.9% of the incorporated city. The Census Bureau's 2024 gazetteer gives Helena 17.168 square miles of land; the 0.9% difference is annexation vintage between a current municipal layer and a federal file.

Inside that boundary there are 3,715 street and alley blocks, and 3,706 of them carry a published grade. We excluded 8,716 driveways and the 20 Interstate 15 segments, and we held nine blocks back. Seven are bridges, which a bare-earth model correctly reads as the ground underneath; one is a stairway; and one is still unexplained.

The seven districts, measured

Read the fourth and fifth columns together and the city splits in half.

District 1 is the hard one. Half its blocks — 252 of 490 — are steeper than 6%, and 112 of them are steeper than 10%. It spans 614 feet of elevation. This is the ground west and south of Last Chance Gulch, the Helena Townsite grid climbing toward Mount Helena. No amount of route planning gets you out of it, because the hill is where the houses are.

District 4 is the easy one. Three of its 329 blocks pass 6%, and not one passes 10%. District 5 is nearly as gentle at 8 of 549. A rider who lives on the valley floor and works on the valley floor is having a completely different experience of this city from a rider six blocks uphill.

Every bar is computed from the same 3,706-block measurement as the table above. District 1 and District 4 are the same city on paper and two different purchases in practice.

District 7 is the surprise: a third of its blocks pass 6%, which puts it closer to District 2 than to the flat valley it sits beside.

Every other name Helena uses for itself

Nobody says "I live in District 5." They say Lenox, or Broadwater, or the Sixth Ward. So we mapped the names onto the districts from the ground rather than from a list: every one of the 22,132 addresses inside the city limits was placed inside its district and inside its platted subdivision, and the shares computed from that.

That produced 233 rows, of which 183 are real place names — 175 platted additions and 8 historic districts. The other 50 are plat filing types rather than places, "Amended Plat" and its variants, carrying 2,404 addresses between them; we do not treat those as neighborhoods.

Thirty of the 183 straddle a district boundary. Helena Townsite — the original 1860s plat and still the largest single name in the city with 2,393 addresses — splits 74% into District 1, 15% into District 3 and 11% into District 2. Chessman and Davis Central Addition splits down the middle, 49% District 5 and 48% District 2. Lenox Addition runs 71% District 6 and 29% District 7.

We publish those splits rather than picking a winner, because a name that spans three districts spans three very different rides, and collapsing it to one row would be an invention.

Homes are address points inside the city limits; the apartment and townhouse column counts parcels the county classes that way, with its share of each district's parcels. The three names per district are the largest by address count.

The steepest blocks in Helena

Two blocks share the paved record, because the two columns measure different things. Adam Run Avenue, 2900–2948, has the steepest paved pitch at 24.8%, and gives almost all of it back before the block ends, at −3.5% overall.

Wallace Street, 311–419, is the steepest paved block end to end at 21.6%, holding 22.2% at its pitch over 147 feet. Clancy Street beats both at 33.4%, and it is gravel.

Two numbers are reported for each block because they answer different questions. The end-to-end grade is what a route adds up. The steepest 30-meter pitch is what your legs meet, and it is the number every published "steepest street" figure in any city is actually quoting. Adam Run Avenue shows why both are needed: 3.5% end to end, 24.8% in the middle.

A single block is still held back. S Warren Street, 1–49, measures 27.3% at its pitch on a paved 142-foot block, and no bridge, tunnel or stairway in the map explains it.

The USGS point service independently confirms its end-to-end grade at 21.08% against our 20.85%, so the block is genuinely steep. What is unconfirmed is whether that 27.3% pitch is pavement or a retaining wall. Until someone stands on it, the block is counted and named but not published as a grade.

And one block turned out to be a staircase. Edwards Street, 1–199, runs the full length of a mapped flight called The Secret Staircase — and it is also the only segment in Helena's entire 17,499-row road file carrying an otherwise unexplained surface code. Two independent records, the same answer.

The alleys, and the gravel

Two things the district table does not show will change how your Helena rides actually feel.

The first is the alley network. Helena's townsite grid is alleyed, and those alleys are a real network: 602 alley blocks running 46.1 miles, against 238.6 miles of street. District 3 has the densest at 135 alley blocks across 9.6 miles, with District 5 next at 119 and District 6 at 86.

An alley is not a bike lane and nobody signs it as one, but it is a paved or graded route with almost no through traffic, and in a grid city it parallels every street you would otherwise ride. If your commute runs through the older part of town, the alley one block over is very often the calmer version of the same trip.

The second is gravel. Not every Helena street is paved, and the unpaved share is concentrated exactly where the hills are: 42 of District 1's 490 blocks are unpaved (8.6%), and 40 of District 7's 472 (8.5%). District 3, by contrast, has three unpaved blocks in 334.

That matters more than it sounds, because a loose surface and a steep grade compound. The steepest block in the entire city — Clancy Street between 250 and 298, at 33.4% — is gravel, and so is Division Street at 22.3% and South Rodney at 21.6%. Three of the five steepest blocks in Helena are unpaved.

If you live in District 1 or District 7, that pairing is the argument for a wider tire regardless of what you think about snow. A 4-inch tire on loose gravel at 15% does something a 2.6-inch city tire cannot, and it does it in July as well as January.

What this means for a route as well as a purchase

A useful habit in a city shaped like this one: plan the climb first and let the descent look after itself.

Helena's grid runs roughly east–west across the slope and north–south up it, so a route that keeps to the cross-slope streets trades distance for gradient. The measured difference is large. Ride east–west across District 1 and you are mostly on blocks near its 6.1% median; commit to a north–south block and you are into the 112 blocks that pass 10%.

The same logic explains why the Centennial Trail is worth a detour even when it is not the direct line. It is the one continuous route in Helena that stays on the valley floor, and the valley floor is where 0% of District 4's and District 5's blocks pass 10%.

The rider is half the problem, and weight is most of that half

A grade is a fact about the ground. What it costs you is a fact about you. So we put the rider into the arithmetic: rider mass, bike mass, and the rider's own sustainable power, on Helena's own measured grades.

The model is the standard one — gravity, rolling resistance and air drag against the motor's nominal rating plus what the legs contribute. Rider power comes from published critical-power measurements: 4.17 W/kg for trained riders and 3.19 W/kg for untrained riders, from Chorley and colleagues in the European Journal of Applied Physiology (2020). Those numbers come with four conditions attached, and a page that quotes them without the conditions is quoting them wrongly.

First: critical power is the hardest effort a rider can hold until they stop, which is nobody's ride to work. Hold it up Rodney Street and you arrive in no state to do anything else. Second: the tables below therefore report half of it, and that half is our editorial choice rather than anything the study found.

Third: the group the study calls untrained was still playing sport weekly, which puts a first-time e-bike buyer somewhere below them rather than among them. Fourth: twenty men, average age 39, is the entire sample — carrying watts-per-kilogram from that group to every rider in Helena is a stretch, and we would rather name it than bury it.

On a 68.4-pound bike with a 750-watt motor, at an easy effort and on untrained legs, the model produces this, in miles per hour:

Below about 3.2% every rider sits on Montana's 20 mph ceiling. Above it, the curves fan out — and the gap between them is body weight, not fitness.

Now the finding that should change what you buy.

On District 1's 90th-percentile block — 12.6%, and there are 112 blocks in that district steeper than 10% — a 130-pound rider holds 12.1 mph and a 250-pound rider holds 8.9 mph, both on untrained legs. The gap is 3.2 mph from body weight alone, on the same bike, with the same motor, at the same effort.

Hold the weight at 190 pounds and swap untrained legs for trained ones, and you gain 0.5 mph.

Body weight matters about 6.4 times more than fitness on a Helena hill. None of that is a judgment about anybody's body; it is what the equation does with mass.

The consequence points straight at the spec sheet: a heavier rider should buy more torque rather than train harder. Two of the bikes below publish 110 N·m and one publishes 92; the entry models publish 55 to 65. On the flat that difference is invisible. On Wallace Street it is the whole ride.

And note the top three rows. Below about 3.2% — which is the median Helena block — every rider at every weight is pinned at the same 20 mph, because that is where Montana's ceiling bites rather than the hill. On the valley floor you are buying comfort, range and load capacity. You are not buying a climb.

What a grade costs, in watts

The same arithmetic, turned around: instead of asking how fast a rider holds, ask how much power it takes at the wheel to hold a speed on each of Helena's grades, for a 190 lb rider on a 68.4 lb bike. Read down any column and the number climbs faster than the grade does.

On the median block's 2.0%, 20 mph asks 524 W; on the 3.2% pitch it asks 647 W; from District 1's median block upward every speed on the row is past what a 750 W rating gives. That gap is what the legs cover or the speed gives up, and it is why the motor's low-speed pull, its torque, decides the west side.

The bike's own weight, in the same arithmetic

Every pick weight the makers publish, run through the model at a fixed 190 lb rider on untrained legs at an easy effort. The spread between the lightest and heaviest bike on District 1's 90th-percentile block is 1.1 mph, which is the arithmetic behind the stairs section: bike weight decides whether you can carry it, and only at the margin how fast you climb on it.

Miles per hour held. Up to 3.2% every row sits on Montana's 20 mph ceiling, so those columns are omitted, and so is the 33.4% gravel block where every bike holds 4 to 4.5 mph.

Trained legs, for comparison

The same table as the rider-weight one above, with the study's trained figure of 4.17 W/kg in place of 3.19, still at the easy half of that effort used throughout. Read it against the untrained table and the gap is half a mile an hour on the hill; read either table down a column and the gap between a 130 lb and a 250 lb rider is three miles an hour.

Height, and what the makers actually publish

Fit is not modeled here; it is read. Twenty of the 26 models we examined carry the manufacturer's own recommended rider-height range, and those are quoted exactly.

The fit ranges, and why they are not interchangeable

The spread matters more than most buyers expect. Eunorau's META20 is published at 5'1"–6'1" and its META275 pair at 5'6"–6'1" — five inches of difference in where the range starts, between two bikes in the same catalog.

The Defender and the FLASH LITE 2.0 reach highest at 6'4", and Addmotor's Kunlun matches them at 5'4"–6'4". The G30-CARGO starts lowest of the two-wheelers at 5'1"–6'2", and the ONE-TRIKE 2.0 at 5'2"–6'1" is the only trike here that publishes a range at all.

The one to know if you are tall is Qiolor. The Tiger JR and Tiger RL are both published at 5'1"–5'9" — a genuinely short-rider fit with a ceiling below six feet. At six foot those two are not your bikes whatever else recommends them, and the Defender or the FLASH LITE is.

Six models publish no range we could find, and those cells stay empty. No fit advice on this page rests on a number a maker did not print.

The winter is cold, not deep

Helena's riding season is longer than "Montana" makes it sound, and the reason is that Helena is dry.

The official station inside the city records 169.9 nights a year at or below freezing — close to half the calendar. But it records only 37.2 inches of snowfall against 11.4 inches of total annual precipitation, and snow lies on the ground 56.5 days a year, with three inches or more on just 31.6 of them.

The dark bars run six months long. The red ones only really run two.

So the picture is not six months of impassable snow. It is six months of cold, clear, often dry pavement, with roughly two months in which snow is actually underfoot on most days. January is the only month where snow lies more often than not.

That shapes the purchase in two directions. Fat tires earn their place for the eight weeks snow is actually underfoot. The other four months are a cold problem, and cold is a battery problem before it is a traction problem.

So do this, from November through March: charge the battery indoors and store it indoors. In a city with 169.9 freezing nights, that one habit matters more than any spec on this page — a pack that starts the morning at room temperature is the part of winter range you actually control.

How far a charge goes on Helena's hills

A mile on a Helena hill costs more of the battery than a mile on the flat, and the table below says how much more: the energy a mile takes on each grade against a flat mile, at the same 12 mph, for the same 190 lb rider on a 68.4 lb bike. It is a ratio, so motor and drivetrain efficiency cancel out and it holds for any battery and any bike.

Read it this way. A bike a maker rates at 50 flat miles has about 11 miles of climbing in it on District 1's median block, and about 6 on its 90th-percentile block, before the cold takes its share. Since a Helena commute climbs one way and descends the other, a west-side round trip sits between the flat row and the climbing row, and a valley-floor trip stays on the flat row.

Your own pedaling, which the arithmetic puts at an easy half of critical power, reduces every multiplier in the table a little, at the price of arriving warm.

The stairs problem is real, and it has a number

Helena has 1,049 apartment and townhouse parcels, and they are not spread evenly. District 5 is the most apartment-dense at 11.0% of its parcels, District 2 next at 10.5%.

Look at District 2 again in the district tables above. It is also the second-steepest district in the city — 36.6% of its blocks over 6%, 14.3% over 10%. A renter on the Corbin or Blake Addition side of town faces a hill on the way home and a staircase at the end of it. That rider has a different problem from everyone else in this guide, and the answer is not torque. It is mass.

There is a federal benchmark for how much mass. The revised NIOSH lifting equation sets a load constant of 23 kg — 51 pounds — and that figure is the ceiling for a lift performed under ideal conditions: load held close to the body, hands near knuckle height, minimal vertical travel, square to the body, infrequent, with good handles. Every other term in the equation is a multiplier that only reduces it.

Carrying a bike up two flights violates nearly every one of those conditions at once. The load is held away from the body, the vertical travel is a story, the coupling is a frame tube rather than a handle, and it happens twice a day.

The lightest bike in this guide is 61.7 pounds. Every machine here is already above the ideal-conditions ceiling before a single multiplier is applied. We are not going to pretend otherwise, and we would rather say it plainly than sell a 92-pound bike to someone with a third-floor walk-up.

What the numbers do let us do is rank honestly. Fifteen of the seventeen picks below carry a manufacturer-published weight, and they run from 61.7 pounds to 95.0 pounds — a spread of 33.3 pounds. Six of them come in under 70.

On a staircase, 33 pounds is the difference between awkward and impossible. If you are carrying it, the weight column below is the only column that matters. If you have a ground-floor garage or a bike room, ignore it and buy torque instead.

What Helena leaves you to choose from

Two screens run before any recommendation on this page, and together they cut hard.

Montana's 20 mph test does most of the cutting. Of the bikes we stock, 28 are legally bicycles here; the rest are mopeds, either because the motor will push a 170-pound rider past 20 mph or because they run on three wheels.

Screen that down to what is in stock today and what we could verify at the manufacturer, and 18 bikes across three brands are left: Eunorau, Addmotor and Qiolor. Seventeen of them are picked below; the eighteenth was dropped because its manufacturer page no longer resolves and we could not read a single specification for it at the maker.

Eighteen is the whole field, and it is why some areas below carry two picks instead of three.

Every price, every variant and every stock position below was read from our own store on September 15, 2026. Every weight, payload, torque figure and rider-height range was read from the manufacturer's own page the same day.

Area 1 — The west-side hill commute

Who this is for: you live in District 1, 2 or 7 and ride one to three miles each way, most days, on ground where half your blocks are steeper than 6%.

The spec that decides it: torque. Watts will not tell you. Every bike here is capped at the same 20 mph, so the motor rating tells you nothing about the hill. What turns the wheel at 6 mph on a 12% block is newton-meters.

The Tiger JR in the maker's own frame: 20-inch fat tires and a moped-style bench seat, the layout that puts 87 lb under a short rider.

Both hub motors are in the frame. The front one is what keeps pulling on a February street.

The bench seat and the rear rack are what a 440 lb payload ceiling is for.

Free US shipping on all three, US-based support, and we file the warranty claim ourselves.

Who should read a different section: if your commute never leaves the valley floor, all three of these are more bike than the ground asks for — go to Area 2. If you carry it upstairs, go to Area 4.

Area 2 — The valley floor and the Centennial Trail

Who this is for: Districts 4, 5 and 6, two to six miles a day, on ground where fewer than 2% of blocks pass 6% and none passes 10%.

The spec that decides it: not torque. On a 2% grade every rider at every weight in our model sits at the 20 mph ceiling, so the hill has stopped being the constraint. What matters is comfort, the ability to get on and off, and that the bike is a bicycle in Montana — because the Centennial Trail is the point of living down here, and a moped may only be pedaled along it.

The step-through gap and the long rear rack, on the frame that makes $1,199 the cheapest way onto the trail.

A step-through commuter with a rear rack, the shape District 5's flat blocks reward.

The same step-through frame as the 1.0, here in one of the five colorways in stock.

All three ship free anywhere in the US, and the warranty is ours to chase, not yours.

Who should read a different section: under 5'6", neither META275 covers you — Eunorau starts that range at 5'6". The META20 in Area 4 is published from 5'1", and Qiolor's Tiger JR in Area 1 from 5'1" as well.

Area 3 — Winter

Who this is for: anyone who intends to keep riding through the 56.5 days a year snow is actually lying, and the 169.9 nights it freezes.

The spec that decides it: tire width first, then drive. Four-inch tires float on packed snow in a way that a 2.6-inch city tire does not. Two-wheel drive matters more here than it does anywhere in this guide, because the front wheel keeps pulling when the rear breaks traction on ice.

This area carries two picks rather than three, for the reason given above: the third candidate's maker page no longer resolves, so none of its figures can be read.

The Tiger RL in the maker's own frame: the same 20 × 4.0 tires as the JR, which is the whole winter argument for it.

The 3.0 in Raven, the colorway in stock: the same two motors and 4-inch tires as the 2.0.

One habit beats either of these two. Charge and store the battery indoors from November through March. Every bike here ships free anywhere in the US, with US-based support and a warranty we handle for you.

Area 4 — The walk-up

Who this is for: anyone in Helena's 1,049 apartment and townhouse parcels — concentrated in District 5 and District 2 — who carries the bike to a landing twice a day.

The spec that decides it: weight, and nothing else. Every bike here clears the 51 lb NIOSH ideal-lift constant already, so the job is to get as far under the rest of the field as possible.

Smaller 24-inch wheels are part of how the META24 comes in at 61.7 lb.

The hinge at mid-frame is the whole reason it is in the walk-up area.

The rear shock under the seat is the full suspension, on the lightest full-size frame here.

A folding frame on 20-inch fat tires, with the seat height that reaches a 6'4" rider.

Free shipping, US support, and a warranty we handle — on every bike in this section.

Who should read a different section: if you have a garage or a ground-floor bike room, weight stops mattering and torque starts. Go back to Area 1.

Area 5 — Three wheels, and the rule nobody tells you

Who this is for: riders who want stability — because of balance, a hip, a knee, or simply preference — doing one to four miles of errands. It is the fifth-largest theme in our own demand harvest, behind winter, hills, the law and where to buy, and it is the area where this page has something to say that no other page does.

Read this before you buy a trike in Montana. An electric trike cannot meet the "two tandem wheels" requirement in § 61-8-102(7), and it is not propelled solely by human power. So it is not a bicycle here. It is a moped.

That costs you nothing at the curb — no plate, no license, full use of every street and bike lane. What it costs you is the path. Under § 61-8-608(3)(b) a moped may be on a sidewalk or a bicycle path "only under human propulsion," so the Centennial Trail is a pedal-only proposition on three wheels.

If the trail is why you are buying, buy two wheels and a step-through frame instead. Getting this wrong will cost you the single route most Helena riders use most days, and no accessory buys it back. If your riding is streets and errands, the trikes below are excellent and the rule barely touches you. Knowing which side of that split you are on is worth more before the bike arrives than after.

Two rear wheels and a basket between them, on a folding step-through frame.

The backrest seat and the rear basket, on the trike with the deepest stock here.

Backrest, rear basket and front basket, on the one trike here that publishes a rider-height range.

Every one of these ships free in the US, with support you can phone in February.

The two-wheeled alternative: the Addmotor Garootan M-81 in Area 2 is a step-through at $1,199 — the same money as the Citytan, with a low frame instead of a third wheel, and full legal use of the trail under power.

Area 6 — Cargo and the school run

Who this is for: one to five miles with a load — the school run, the grocery run, the trailer.

The spec that decides it: the payload ceiling, and whether the maker counts you inside it. Both picks here publish a number in the 440–450 lb range, and Eunorau is explicit that its figure includes the rider. Read it that way and a 200 lb parent has roughly 240 lb left for children and shopping, not 440.

The Graoopro in Neptune Blue, the colorway in stock: the long rear deck and rack that carry the 450 lb payload ceiling.

A longtail cargo frame: the rear deck is what carries the 440 lb total payload.

The seventeen picks, side by side

Every figure below is the maker's own published number, read on September 15, 2026; an empty cell is a figure we could not read at the maker that day, and nothing on this page rests on it. Prices are our store's on the same day. The area column is where each bike is argued for above, and its link takes you back to that area.

Two weights, the Citytan M-315's 95 lb and the Citytri E-310's 86 lb, are Addmotor's figures from its customer question-and-answer replies rather than a specification table.

Where you may actually ride in Helena

Three surfaces, three different answers.

Streets and sidewalks. Open to e-bikes. State law gives a bicycle the roadway and the paved shoulder, and Helena's own position is that its open-lands restriction "does not prohibit use on city streets and sidewalks."

On a sidewalk, yield to pedestrians and give an audible signal before passing, under § 61-8-608(1). Section 61-8-608(2) also lets the city ban sidewalk riding outright with a traffic control device, so a posted sign is enforceable and worth reading.

The paths, and what the law asks of the bike

Paved shared-use paths, including the Centennial Trail. Open to a Montana bicycle under power. Not open under power to a moped — so not to a trike, and not to anything that will push a 170 lb rider past 20 mph.

What the law asks of the bike itself. § 61-8-607 applies at dawn, dusk and night, which in a Helena December is most of a commute: a white front lamp visible 500 feet, a red rear lamp or reflector visible 500 feet, reflective material visible 500 feet from each side, and a brake that will stop you within 25 feet from 10 mph. That is the whole equipment list, and it applies to mopeds as well as bicycles.

The South Hills, and the one rule that surprises people

Mount Helena is a natural park by ordinance, and the City reads an e-bike as motorized there. That is why no electric mountain bike is recommended here. The City's position, adopted April 14, 2021, is that e-bikes "should be defined as motorized and prohibited from use as noted in Helena City Code 7-12-3 C., or by land deed," and that this "predominantly pertains to Helena Open Space Lands on Mount Helena and Mount Ascension."

We will be precise about what that is and is not. The City's own Open Lands page states the prohibition in terms of "motor vehicles such as ATVs, 4-wheelers, trucks and motorcycles" and does not name e-bikes.

The exclusion follows from treating the motor as making the machine motorized — the position the City recorded in 2021 — rather than from a line of code that says "electric bicycle."

The ordinance itself is one sentence. Helena City Code 7-12-3 C. reads: "It is unlawful to hunt, trap, gather firewood or use motor vehicles in any natural park except as specifically authorized."

The chapter's definitions at 7-12-1 name a single natural park — "Mount Helena City Park has been designated, by resolution, as a natural park" — so the section reaches Mount Helena directly, and Mount Ascension only through the open-space and land-deed route the City's 2021 statement also names.

So the code says "motor vehicles," the City's 2021 position is that an e-bike counts as one there, and the City's public page names ATVs and motorcycles without naming e-bikes. Those are three different sets of words, and we publish all three.

Keep the singletrack for an acoustic mountain bike. On ours, Helena's paved network and the Centennial Trail are open under power, which is what Area 2 is about — and check with Helena Parks, Recreation and Open Lands before assuming either way.

Where Helena's bike network is, mile by mile

The City's trail layer carries 198 segments and 130.7 miles, and most of it is not for this bike. Split by the City's own type field: 18.0 miles of on-street designated bike lane in 11 segments, 4.3 miles of signed bike route, 26.8 miles of urban multi-use path, and 80.2 miles classed Urban-Other.

The multi-use miles include the Centennial Trail and the paved paths along Custer, Montana Avenue and US 12. Urban-Other is where the South Hills singletrack lives.

The segment the City's file spells "Urnam-Other" is counted as Urban-Other. The nine untyped and two proposed segments are shown but not counted as network you can ride. The City records a surface type for 36 of the 198 segments; where it does, the multi-use paths are mostly asphalt and seven are gravel.

Placed inside the seven districts by where each segment's vertices fall, the network is lopsided in a way the district table above predicts. District 1 holds the singletrack; the multi-use paths and bike lanes sit on the valley floor in Districts 3, 4, 5 and 6, and the longest paths run outside the seven districts altogether.

"Outside the districts" is ground inside the trail file but outside the seven Citizens Council polygons: the South Hills open lands and the county paths. Miles are the layer's own, and a row's total includes the untyped and proposed segments that have no column.

The ten longest named routes, by the City's mileage:

• Mt Helena Ridge Trail: 5.8 mi, Urban-Other
• Centennial Trail: 4.3 mi, Urban Multi-Use and signed bike route
• Diretissima Trail: 3.4 mi, Urban-Other
• Rodney Ridge Trail: 3.4 mi, Urban-Other
• E US Highway 12 Paved Path: 3.0 mi, Urban Multi-Use
• Centennial Park Trail: 2.5 mi, Urban Multi-Use
• N Montana Ave Paved Path: 2.2 mi, Urban Multi-Use
• William Gruber Loop: 2.1 mi, Urban Multi-Use
• Eddye McClure East: 2.0 mi, Urban-Other
• Entertainment Trail: 2.0 mi, Urban-Other

For this bike the list to remember is short: the Centennial Trail and the paved paths, the on-street lanes on the valley floor, and the streets everywhere.

The valley-floor picks are chosen for that network and nothing else. The Mount Helena Ridge and Rodney Ridge trails are on the list because they are long, and the City's file lists both as Forest Service-administered, so their e-bike status is the Forest Service's to set and is not retrieved here. The 1906 Trail and the rest of the Mount Helena City Park network are the ground the City reads as closed under power.

What it costs against driving in Helena

The purchase is easier to judge against what it replaces. AAA's Your Driving Costs 2026 puts the US national average cost of owning and operating a new car at $12,863 a year — $1,071.92 a month, or 86¢ a mile at 15,000 miles a year, with fuel at 17.3¢ a mile on gasoline averaging $4.152 and maintenance, repair and tires at 11.7¢ a mile.

The EIA's weekly survey prices the Rocky Mountain region separately, and had regular at $4.438 a gallon in the week of September 14, 2026, above the $4.152 in AAA's figure.

Parking is the number a Helena commuter actually feels. The City's rate sheet prices downtown pay-to-park zones at $1.50 an hour to a $13 daily maximum, with the first 20 minutes free once you register your plate at a kiosk or in the Passport app, and evenings and weekends free.

Monthly permits run $65 on the street, $75 in a lot, $95 in a garage and $105 for all of them except the Jackson Street garage, and a residential permit is $30 a year. A kiosk or lot violation is $30, halved if paid within two days. An e-bike parks at a rack for nothing.

The electricity line comes from the same hill arithmetic as the range table rather than from a maker: at 12 mph the flat costs about 10 watt-hours a mile from the wall and District 1's median block about 50, with the motor doing all the work.

The wall-to-wheel efficiency is taken as 80 percent, the same figure the speed tables use, and the price is the EIA's Montana residential average of 15.14¢ per kilowatt-hour for June 2026.

A full year of a valley-floor commute is a few dollars of power; a west-side one is about eleven. Against that, a year of street permit is $780, and the $1,399 picks cost the same as about 22 months of it.

What the table does not claim: an e-bike does not replace a car on a Helena winter's worst days, for a trailer's worth of groceries, or for the drive to Great Falls. It replaces the miles that make up most of the year, the ones the City's parking rates are priced for.

Every Helena neighborhood, and where to start

The district tables above are the city's own geography. The tables below are the same measurement by the names people use: every one of the 183 real place names in the City's plat and historic-district layers, 175 platted additions and 8 historic districts, each under the district that holds most of its addresses, with the split printed where a name straddles a line.

The grades are the name's own. Each graded block was placed by the midpoint of its centerline inside the plat polygon it falls in, so a name's block count is a floor: 457 of the 3,706 blocks fall in plat-filing polygons or on unplatted ground and belong to no name.

A name with three or more graded blocks gets a terrain reading; sixty names have fewer and are listed with their numbers and the reading "too few blocks". Of the names that can be read, 53 are flat, 22 gentle, 9 hilly and 39 steep.

How to read it. Over 6% and over 10% count a name's blocks by their steepest 30-meter pitch. Relief is the vertical spread across its blocks. Terrain is the share over 6%: flat under 5%, gentle from 5% to under 20%, hilly from 20% to under 40%, steep from 40%.

Start here sends a flat or gentle name to the valley-floor picks and a hilly or steep name to the torque picks; a name with too few blocks to read takes its district's answer, Districts 1, 2 and 7 at the hill and the other four on the valley floor. Stairs, winter, a load or three wheels override it, which is what the areas above are for.

Nearest bike route is the distance from the middle of the name to the closest signed bike lane, bike route or multi-use path in the City's trail file.

District 1: 27 names

District 2: 29 names

District 3: 13 names

District 4: 36 names

District 5: 28 names

District 6: 20 names

District 7: 30 names

Honest ledger

Helena is an unusually good e-bike city with three specific problems, and they are not the ones a national buying guide would warn you about.

What is genuinely good about riding in Helena

• The valley floor is as easy as riding gets: three of District 4's 329 blocks pass 6%, and none passes 10%.
• Montana asks less of you than almost any state — no class system to navigate, no helmet law, no minimum age, no registration and no license for anything in this guide.
• It is dry. Thirty-seven inches of snowfall falls across a year that receives only 11.4 inches of precipitation in total — snow is bulky, not wet — and it lies on the ground just 56.5 days.
• Singletrack begins at the edge of downtown, which almost no American state capital can say.

What will cost you, and what to do about it

• Half of District 1's blocks are steeper than 6%. Buy torque rather than watts, and read the weight table before you assume you will be fine.
• One hundred and sixty-nine freezing nights a year is a battery problem. Charge and store indoors from November to March.
• The best trails in town are closed to your e-bike. Keep an acoustic bike for those, and ride the paved network and the Centennial Trail on this one.
• Three wheels means pedaling the Centennial Trail. If the trail is the reason you are buying, buy a step-through instead.
• Every bike here is above the 51 lb ideal-lift constant. If you live up two flights, the 61.7 lb META24 and the folding META20 are the only two we would put in front of you.

Frequently asked questions

Are e-bikes legal in Montana?

Yes. Under MCA § 61-8-102(2) a "bicycle" "includes an electrically assisted bicycle," and § 61-8-102(7) defines that as a two-wheeler whose motor cannot propel a 170-pound rider faster than 20 mph on level pavement. A bike that meets it has every right a bicycle has. A bike that does not is a moped, which is still legal on the street.

Do e-bikes need registration or a license in Montana?

No, for anything in this guide. Registration under § 61-3-301 and licensing under § 61-5-102 both attach to motor vehicles, and § 61-1-101(41)(b) excludes a bicycle, a motorized scooter and a moped from that definition by name.

What class of e-bike is legal in Montana?

None of them, because Montana does not use classes. The words "class 1," "class 2" and "class 3" appear nowhere in the definition section and in none of the 1,222 section headings of Title 61. What matters here is a single 20 mph test and a wheel count.

Are e-bikes allowed on bike trails in Montana?

On a paved shared-use path such as the Centennial Trail, yes — if the machine is a Montana bicycle. § 61-8-608 restricts only mopeds and motorized scooters to human propulsion on a sidewalk or bicycle path. On Helena's natural-park trails in the South Hills, the City has treated e-bikes as motorized and excluded since April 14, 2021, reading the "motor vehicles" in Helena City Code 7-12-3 C. to include them.

Is a helmet required for an e-bike in Montana?

Not by state law, at any age. The only headgear section in Title 61 is § 61-9-417, "Headgear required for minor motorcycle riders," and a bicycle is not a motorcycle under § 61-1-101(43)(e). Wear one anyway.

How steep a hill can an electric bike climb in Helena?

On a 750-watt bike at an easy pedaling effort, a 130-pound rider holds about 12.1 mph on a 12.6% block and a 250-pound rider about 8.9 mph. Helena's steepest paved block, Wallace Street between 311 and 419, runs 22.2% at its pitch — rideable at around 5 to 8 mph depending on your weight, and genuinely hard work.

What is the best electric bike for hills in Helena?

The highest-torque machine we can sell you that is still a bicycle under Montana law: the Eunorau FAT-AWD 2.0 at 110 N·m, with two motors. On the flat it is indistinguishable from a 55 N·m bike, because both are capped at 20 mph. On a District 1 block it is not.

Can an electric bike handle snow in Helena?

For most of the winter the question is cold rather than snow — snow lies on 56.5 days a year, and three inches or more on 31.6 of them. Four-inch tires and two-wheel drive make those days rideable. The rest of winter is a battery question: charge and store the pack indoors and you keep most of what it holds.

How many miles can an electric bike go in Helena?

Farther on the valley floor than on the west side, and the difference is larger than most range claims allow for. Climbing consumes energy that flat riding does not, and cold reduces usable capacity. Treat any published range as a warm, flat, unloaded figure and plan the winter hill commute at well under it.

Is an electric trike a good idea in Helena?

For streets and errands, yes — they are stable, and the ONE-TRIKE 2.0 publishes a 440 lb payload ceiling and a 5'2"–6'1" rider-height range. For the Centennial Trail, no: a trike is a moped in Montana and may only be pedaled on a bicycle path. Decide which of those two matters more to you before you buy.

How do you carry an electric bike up stairs?

Start by buying a lighter one. The Eunorau META24 at 61.7 pounds and the folding META20 at 63.4 are the two lightest machines in this guide, and both still sit above the 51-pound load constant that the revised NIOSH lifting equation sets for an ideal lift. Take the battery out first — that is several pounds off in one movement — and carry the bike by the frame's down tube with the wheels turned away from your shins.

Where can you ride an electric bike in Helena?

On every street and paved shoulder under § 61-8-605, and on sidewalks under § 61-8-608; the City's 2021 statement says its open-lands decision "does not prohibit use on city streets and sidewalks." On the Centennial Trail, state law lets a bicycle ride under power; the City left path use to a later discussion whose outcome is not published, so confirm with Helena Parks. Closed under power: the singletrack on Mount Helena and Mount Ascension.

Is an electric mountain bike worth it in Helena?

Not for the trails that make Helena a mountain-bike town. The City treats an e-bike as motorized on its open-space lands, so the 1906 Trail and the Mount Helena City Park network are closed to it under power; the City's file lists the Mount Helena Ridge and Rodney Ridge trails as Forest Service-administered. A full-suspension frame earns its place on the west side's 42 unpaved District 1 blocks, and the Defender is the one among the picks.

Is a high-speed electric bike legal in Montana?

On the street, yes; on the path, only pedaled. A bike whose motor pushes a 170-pound rider past 20 mph is not a bicycle under § 61-8-102(7). With pedals, no more than 2 brake horsepower (about 1,500 W) and no more than 30 mph unassisted, it is a moped: no plate or license, but a path only under human propulsion. Past any of those limbs, it is a motor vehicle with registration and a license.

Why are electric bikes so expensive?

Against a car they are not. The seventeen picks on this page run $1,199 to $2,599 once, and AAA's 2026 US national average for owning and running a new car is $12,863 a year. In Helena the comparison is sharper because of parking: a downtown street permit is $65 a month, so the $1,199 Addmotor Garootan M-81 or Citytan M-315 costs the same as about 18 months of permit and then parks free.

Why buy it from us

Four things come with every bike on this page, and they are worth more in Helena than in most places.

Free shipping anywhere in the US, which matters when the nearest dealer floor for most of these brands is a long drive. US-based support, so a warranty question in February is a phone call and not an overseas email thread. And we handle the warranty claim for you rather than handing you a maker's contact form — you talk to us, we deal with them.

And you can pay how you like: Shop Pay installments, PayPal, Apple Pay and Google Pay are all live at checkout, so a $1,699 bike does not have to be $1,699 today.

You are also buying from the only page that has measured your street. Every grade, every district and every rider-weight figure above came from public data we recomputed ourselves, and the scripts and datasets behind them ship with the page.

What it costs to get this wrong

The failure modes in Helena are specific, and they are expensive.

Buy a bike over the 20 mph line and you have bought a moped — the Centennial Trail, the paved network and every sidewalk are closed to it under power, and that is most of the riding a Helena commuter actually does. Buy a trike for the trail and you have made the same mistake with three wheels.

Buy 55 N·m for a District 1 address and the hill will win about twice a week until the bike lives in the garage. Buy a 92 lb bike for a third-floor walk-up and it will be a 92 lb bike in the stairwell by March.

One of them is not just inconvenient. Under § 61-8-601(1) it is a misdemeanor to do any act forbidden in Montana's bicycle part — so riding a moped under power along a bicycle path, or riding at dusk without the lamps § 61-8-607 requires, is something an officer can cite you for, on a trail the police ride too.

Nobody wants to be stopped on the Centennial Trail explaining a speed setting, and the fine is avoidable for free by leaving the limiter alone.

None of these is recoverable with an accessory. They are all avoidable by reading two numbers before you order: the assisted top speed, and the weight.

The bottom line

If you live west of Last Chance Gulch, buy torque and stop thinking about anything else. The Eunorau FAT-AWD 2.0 at $1,699 publishes 110 N·m through two motors, which is the most of any bike that is legally a bicycle in Montana, and two driven wheels is also what you want on a February street.

Buy the FAT-AWD 2.0 — $1,699 →

If you live on the valley floor, the hill is not your problem and you should not pay for one. The Eunorau META275 1.0 at $1,399 is 68.3 lb, publishes a 5'6"–6'1" rider-height range so you know before it arrives whether it fits, and on District 5's median block it holds the same 20 mph as anything three times the price.

Buy the META275 1.0 — $1,399 →

And if you carry it up two flights, none of that matters next to mass: the Eunorau META24 at 61.7 lb is the lightest machine here.

Buy the META24 — $1,699 →

Shipping is free anywhere in the US, support is based here, and the warranty claim is ours to file.

When you're ready — and not before. Nothing here expires. Take the district table above, find your street, and note two numbers: the share of blocks over 6%, and whether you have stairs.

Then browse every e-bike we stock with those two numbers in hand, or write and tell us your address and your building. Shop Pay installments are available at checkout if you would rather spread it, and our refund policy is there before you commit, not after. We will tell you which of the seventeen fits, including when the answer is the $1,199 one.

Limitations

Thirteen things this page cannot support, stated plainly. Each one is a limit on our method or a gap in what the published record contains, and none of them is hidden in a footnote.

Limits on what we measured

1. Nine blocks are not published as grades. Seven are bridges, each identified by matching the block against a bridge carrying the same street name in the road-surface map. The eighth, Edwards Street, is a stairway. The ninth, S Warren Street 1–49, has no structure in the map to explain its 27.3% pitch and is held until someone looks at it.
2. No maker in this guide publishes an operating- or charging-temperature range — zero of 26 product pages under a deliberately wide search. In a city with 169.9 freezing nights, that is a real gap in the published record, and it is why no cold-weather range figure appears anywhere above.
3. Addmotor publishes no torque figure on any of its seven product pages we read, so five Addmotor picks carry no newton-meter number.
4. Bike weight is published for 15 of the 17 picks. Two of those figures come from the maker's customer question-and-answer replies rather than a specification table, and are labeled where they appear.
5. Rider-height ranges are published for 20 of 26 models read. Where a maker publishes none, the cell is empty and no fit claim rests on it.
6. A neighborhood's block count is a floor. 3,249 of the 3,706 graded blocks fall inside a named plat polygon; the other 457 sit in the 50 plat-filing polygons or on unplatted ground and are counted in the district table but in no neighborhood row. Sixty names carry fewer than three graded blocks and are shown with their numbers but no terrain reading.
7. The range table is a ratio from the model rather than a measurement of any bike, and the cost table's electricity line is that same model priced at a state-average tariff. No maker in this guide publishes a range on a grade or a cold-weather range, so neither appears here as a mileage.

What the published record does not contain

1. The trike-as-moped reading is the plain text of the statute, not settled law. We located no Montana appellate decision and no Attorney General opinion applying § 61-8-102(7) to an electric trike.
2. Helena City Code 7-12-3 C. says "motor vehicles"; it does not say e-bike. The exclusion of e-bikes from Mount Helena rests on the City's 2021 reading of that phrase, and the City's own Open Lands page names "ATVs, 4-wheelers, trucks and motorcycles." We publish the ordinance and the position together and recommend confirming with Helena Parks, Recreation and Open Lands.
3. Demand shares are over this page's own seed list. Of 1,519 harvested rows, 43 were excluded as local-business noise that a bare place-name pulls in, leaving 1,476; every share quoted is over that figure and describes this harvest, not Helena's search demand as a whole.
4. The elevation control is not fully independent. The USGS point service that validated our grades serves the same 3DEP program as the tiles we measured. It bounds projection, tile indexing and datum together; it cannot by itself confirm that a surface is ground rather than structure. The road-surface map does that job.
5. Prices, stock and variants were read on September 15, 2026 and move.
6. The driving-cost comparison is a national AAA average rather than a Montana figure; only the fuel price and the electricity tariff are regional, and the parking rates are the City's own. AAA's per-mile figure assumes 15,000 miles a year and a new vehicle; an older car carries less depreciation, and how much lower that puts the figure is not measured here.

Expiry conditions

This page needs re-checking if any of the following happens: the Montana Legislature amends § 61-8-102 in the 2027 session; the City of Helena amends Title 7 Chapter 12 or adopts an ordinance naming e-bikes for its open lands; a manufacturer changes a published weight, payload or height range; or a pick goes out of stock.

Six guides that go deeper on the questions this page could only answer for Helena.

• Electric bike buying guide — the general framework behind every recommendation on this page.
• Best commuter electric bikes — if your ride is the valley floor and you want the national picture.
• Best fat tire eBikes — the winter question, treated at length.
• Best folding eBikes — the walk-up question, with more options than Montana's screen leaves here.
• Electric bikes for seniors — and read the trike rule above before you buy three wheels in Montana.
• Electric bikes for heavy adults — payload ceilings and torque, which is what the weight table above is really about.

How we verified this

Every figure here was computed or read from a named source, and the scripts that produced them are kept with the data.

Terrain. USGS 3DEP 1-meter bare-earth lidar, project MT_Statewide_Phase4_B22, published November 14, 2024 — four tiles, 97,478 elevation samples taken every 5 meters along 3,715 blocks inside the Helena city limits. Grades are reported both end to end and as the steepest 30-meter pitch. The chain was validated against the USGS Elevation Point Query Service at 34 blocks: 34 AGREE, 0 DISAGREE, worst single-point difference 0.40 m.

Geography. City of Helena / Lewis & Clark County open data, retrieved September 15, 2026: 7 Citizens Council districts, 17,499 road centerlines, 45,055 address points, 2,299 platted subdivisions, 42,046 parcels, 90 park polygons and 198 South Hills trail segments. Every layer's row count was checked against the publisher's own reported count before use.

Road surface. OpenStreetMap via Overpass, 10,588 highway ways including 97 stairways, 63 bridges and 12 tunnels — used to identify which apparent grades are structures rather than ground.

Climate. NOAA National Centers for Environmental Information, U.S. Climate Normals 1991–2020, station USW00024144 (Helena Regional Airport).

The sources behind the advice

Law. Montana Code Annotated 2025, Title 61, read at the Legislature's own publication; all 1,222 section headings in the title enumerated so that absence claims could be measured rather than asserted. Helena City Code via American Legal Publishing, the City's own codifier.

Rider power. Chorley A, Bott RP, Marwood S, Lamb KL. "Physiological and anthropometric determinants of critical power, W′, and the reconstitution of W′ in trained and untrained male cyclists." European Journal of Applied Physiology 2020;120(11):2349–2359. doi:10.1007/s00421-020-04459-6.

Lifting. Waters TR, Putz-Anderson V, Garg A. Applications Manual for the Revised NIOSH Lifting Equation. NIOSH Publication No. 94-110.

Bikes. Every weight, payload ceiling, rider-height range and torque figure was read from the manufacturer's own product page on September 15, 2026 and deposited. Prices, variants and stock were read from our own store the same day. Where a maker publishes nothing, the cell is empty — we do not fill it in.

Neutrality. We sell the bikes recommended here. Every specification above is the manufacturer's own published figure, recomputed where it enters a calculation, and the gaps in what makers publish are listed in Limitations rather than smoothed over. If you find an error, write to us and we will correct it and say so on the page.
