Eahora's studio photograph of the black Eahora Luna from the front three-quarter, standing in a pool of light in a charcoal studio, under the headline A $799 step-through fat bike., with a badge reading 41 miles at 15 mph on the throttle, 180 lb rider, level pavement, computed

Step-through fat-tire e-bike · 1,000 W rear hub, 1,500 W peak, 90 N·m · 48 V 15 Ah pack, 720 Wh · coil fork and four-bar coil rear shock · hydraulic discs · 20 × 4.0 in tires · 91 lb, rated for 330 lb · 41 miles at 15 mph on the throttle, computed · 28–33 mph, outside the e-bike definition in 49 of 51 jurisdictions · $799, Eahora's own US price · verified November 10, 2026

Quick Answer — The Eahora Luna is a $799 step-through fat-tire e-bike with full coil suspension, a 1,000 W rear hub and a 720 Wh pack. A 180 lb rider on the throttle at 15 mph over level pavement computes to 41 miles; Eahora rates 35 to 45 miles without pedal assist.

Its 28 to 33 mph and 1,000 watts put it outside the e-bike definition in 49 of 51 US jurisdictions, so read where it can be ridden before you plan a commute. Eahora fits it to riders 5'4" to 6'1" (its specification page); find your row in the fit tables.

How we verified this Eahora Luna review

Every figure about the bike was read on November 10, 2026, at Eahora's Luna page, its technical specification page and the owner manual Eahora links for the Luna, then recomputed. Our price, listing and policies were read from our store the same day.

Range and fit come from models whose inputs are printed beside them, and the law section screens Eahora's figures against each state's own definition. The questions this page answers come from search suggestions, Search Console, the headings of 10 competing pages and an AI-search panel.

Because we sell the Luna, give the red flags the same weight as the green. Part of our e-bike reviews.

The Eahora Luna as Eahora prints it

Three figures decide most of what you need to know: a 48 V 15 Ah pack, a 28 to 33 mph top speed and a $799 price. Eahora calls it "the perfect commuter ebike for your weekend adventures or daily commute" (its Luna page).

Price, November 10 $799, ours and Eahora's Both stores

Eahora's figures from its Luna page, its specification page and the owner manual, and our price from our listing, read November 10, 2026; the watt-hours are 48 volts times 15 amp-hours.

Eahora prints a few of these figures two ways, and this page shows both wherever one decides something. The range strip at the top of its page reads "25 - 45 MILES" with no mode named. The manual gives the rider window as "5'4"-6'2"" and torque as "80 -90N/M".

Its charging time is 7 to 8 hours on the manual's Luna page and in the product page's FAQ, and "approximately 4-6 hours if the battery is mostly empty" in the manual's charging section. The FAQ also calls the frame a "reinforced aluminum frame", where the specification page says "High-carbon steel" and the manual "Iron Steel Frame".

What the Luna is: a step through fat tire ebike with full suspension

A fat-tire e-bike with a low, open middle, coil springs at both wheels, a twist throttle, seven gears and hydraulic brakes. Eahora's specification page lists its ideal use as "IP65 weather-proof, off-road / mountain / urban riding". Our fat-tire guide places twelve picks by rider, step-through access among them.

The black Eahora Luna from the front three-quarter on a white background, showing the step-through frame, the battery on the down tube, the headlight, the coil fork and the rear rack

Eahora's front three-quarter of the black Luna, from the same record, used whole; the frame drops low between the saddle and the bars.

The frame is one down tube from the head tube to the crank, with the battery mounted on it and nothing crossing above. That open middle is what makes a step-through: you step a foot through the gap to mount, and there is no bar at hip height to swing a leg over. Our frame-types guide sets the step-through beside the step-over and asks whether the open frame is weaker.

Two of the Luna's Eahora relatives change the decision:

Eahora Frame Drive and pack Brakes Our price
Luna Step-through 1,000 W rear hub, 720 Wh Two-piston hydraulic $799
Terra Step-over 1,000 W rear hub, 720 Wh Four-piston hydraulic $899
Luna II Step-through Two 500 W hubs, 960 Wh Two-piston hydraulic $999

Frames from Eahora's photographs; drives, packs and brakes from Eahora's specification pages for the Luna, Terra and Luna II; prices from our store, all read November 10, 2026.

On paper the Terra is the Luna with a top tube and four pistons in each caliper. Eahora's two specification pages differ in three lines: four-piston calipers on the Terra where the Luna has two, and two weather ratings printed the other way round. Pick the Terra if you want a top tube to grip with your knees or the four-piston calipers, and pay $100 more; our Terra review runs its numbers.

The Luna II keeps this frame and adds a second motor and a bigger pack, two 500 W hubs and 960 Wh, per Eahora's Luna II page. It costs $200 more with us. Our Luna II review covers what the second motor buys.

Two names to know before you search. A search for "Luna" alone also turns up other makers' machines, so search "Eahora Luna" and check the brand on each result. And the frame in Eahora's photographs carries the wordmark JOPAJOCA, the name that also heads the owner manual's Luna page ("JOPAJOCA LUNA"); that is the name Eahora's pictures show on the frame. For the maker, see our Eahora profile and our Eahora collection.

Will the Eahora Luna fit you?

At the Luna's lowest saddle setting, 32.3 inches to the ground, 10 of 100 riders 5'5" in the US Army's ANSUR II survey can sit with both feet flat, and every rider from 5'0" up clears the 24.2-inch standover Eahora prints; the 109%-of-inseam formula sets how high above the crank axle your saddle goes.

Eahora fits the Luna to riders 5'4" to 6'1" with an inseam of 26.8 inches or more (its specification page). Height alone cannot size a bike: among the survey's riders at 5'8", the middle 90% of inseams run from 31.1 to 34.3 inches. Three steps:

  1. Measure your inseam in bare feet, heels to a door frame: snug a thick book up between your legs where a saddle would sit, mark the spine's height on the frame and measure that mark from the floor.
  2. Find your height in the saddle, seat and standover tables below.
  3. Fine-tune the saddle on the bike with the heel check.

Eahora's size drawing, from its Luna page: C is the seat height to the ground, F the standover and B the 48.8-inch wheelbase. How we computed fit explains why no frame dimension is read off it.

Will the saddle go high enough (or low enough) for me?

For a 5'8" rider with the survey's median 32.64-inch inseam, 109% of inseam puts the saddle top 28.9 inches above the crank axle. Eahora prints the seat height to the ground, 32.3 to 40.2 inches, and no bottom-bracket height, so that figure cannot be set against the post; the table gives the distance to aim for when you set it.

Your height Typical inseam Crank axle to saddle top At 106% At 110.4%
5'0" 27.1–29.7 in 24.3 in 23.5 in 24.7 in
5'2" 28.0–31.1 in 25.5 in 24.6 in 25.9 in
5'4" 29.1–32.2 in 26.6 in 25.6 in 27.0 in
5'6" 30.2–33.5 in 27.8 in 26.9 in 28.3 in
5'8" 31.1–34.3 in 28.9 in 27.9 in 29.3 in
5'10" 32.2–35.5 in 30.1 in 29.1 in 30.6 in
6'0" 33.2–36.7 in 31.4 in 30.3 in 31.9 in
6'2" 34.3–37.5 in 32.6 in 31.5 in 33.1 in
6'4" 36.3–39.1 in 34.3 in 33.2 in 34.9 in

Crank axle to saddle top for the median rider at each height in ANSUR II, at 109% of inseam from the pedal less Eahora's 170 mm crank; the side columns use 106% and 110.4%. The inseam range runs from the 5th to the 95th percentile.

Sitting down at a stop is the harder test on this bike. With the saddle at its lowest, here is how many riders at each height can rest both feet flat without leaving the seat:

Your height Typical inseam Inseam minus the 32.3 in seat, median rider Riders flat-footed astride it, of 100
5'0" 27.1–29.7 in −3.9 in 0
5'2" 28.0–31.1 in −2.8 in 0
5'4" 29.1–32.2 in −1.8 in 5
5'6" 30.2–33.5 in −0.6 in 27
5'8" 31.1–34.3 in 0.3 in 66
5'10" 32.2–35.5 in 1.5 in 94
6'0" 33.2–36.7 in 2.6 in 99
6'2" 34.3–37.5 in 3.7 in 100
6'4" 36.3–39.1 in 5.3 in 100

Inseam less Eahora's lowest seat height of 32.3 inches to the ground, for the median rider and the share of 100 at each height in ANSUR II; a negative figure is how far short of flat-footed the median rider sits.

At 5'6", 27 of 100 riders reach the ground seated; at 5'10", 94 do. Below about 5'8", expect to come off the front of the saddle at a light and stand astride the frame, which the open step-through leaves room for. If a seated stop is the worry, our electric bikes for seniors guide has a standstill test you can run today, and a wobbly result points to its three-wheel picks.

Can I put a foot down at a stop?

Every height in the table clears Eahora's 24.2-inch standover: at 5'0", 95 of 100 riders in the survey stand with 2.9 inches or more to spare.

Your height Typical inseam Clear the 24.2 in standover, of 100
5'0" 28.4 in 100
5'2" 29.5 in 100
5'4" 30.5 in 100
5'6" 31.7 in 100
5'8" 32.6 in 100
5'10" 33.8 in 100
6'0" 34.9 in 100
6'2" 36.0 in 100
6'4" 37.6 in 100

Riders of 100 at each height in ANSUR II whose inseam clears Eahora's printed 24.2-inch standover, and the median inseam at that height.

Eahora prints the same 24.2 inches for the step-over Terra (its page). On the Luna's own drawing the standover line rises from the ground to the frame's low point just ahead of the crank, and the table uses Eahora's figure as printed.

Will I feel cramped, or stretched?

Eahora prints a 22.8-inch "Reach Distance" and a 42.5-inch handlebar height for the Luna, and the manual's Luna page prints the bar at 1,120 mm, which is 44.1 inches. No grip position is published, so the lean to the bars is not computed here (Limitations).

The printed heights do give the rise. Eahora's 42.5-inch bar sits 10.2 inches above the saddle's lowest setting of 32.3 inches, and the manual's figure puts it 11.8 inches above (size and geometry; owner manual).

How much weight goes through my wrists?

Road racers on the hoods carry about 15% of their body weight through the bars (Carahalios 2015); for the Luna this page computes no figure. The grip's position relative to the saddle, the input a hand-load figure needs, is not published for the Luna, so the hand load is not computed here.

How do I set the saddle when it arrives?

Set the saddle so your knee stays bent 25 to 35 degrees with the pedal at the bottom, the range Peveler, Pounders and Bishop (2007) report from the cycling literature. To test the height, mount the bike beside a wall for balance, put a heel on the pedal at its lowest point and back-pedal slowly.

With the heel on the pedal at its lowest point, the leg should just straighten. If your knee stays bent, the saddle is too low, so raise it; if your hips rock side to side to keep the heel on the pedal, it is too high, so lower it. Then ride with the ball of the foot on the pedal; that small shift is the bend the formula builds in.

At the lowest seat, 32.3 inches, fewer than half the riders shorter than 5'8" in the survey sit flat-footed, and every height from 5'0" clears the 24.2-inch standover. Set the saddle by the 109% formula, then the heel check.

How we computed fit

Three formulas, one survey and Eahora's printed geometry; nothing is measured off a picture. Hamley and Thomas set the saddle at 109% of inseam from the pedal; LeMond sets it at 88.3% from the crank axle, the same saddle; and Peveler, Pounders and Bishop give the 25 to 35 degree knee.

Knee at the bottom of the stroke 25 to 35 degrees Peveler, Pounders and Bishop (2007)

Eahora's figures read November 10, 2026; the survey and the studies as cited.

One rider, worked through. A 5'8" rider with the survey's median inseam of 32.64 inches: 32.64 × 1.09 = 35.58 inches from the pedal to the saddle top. Take away the 6.7-inch crank and the saddle sits 28.9 inches above the crank axle. LeMond's 88.3% gives 28.8 inches from the same axle, within a tenth of an inch.

That agreement is the formula's check. Averaged over the survey's 6,068 riders, LeMond's setting plus a 170 mm crank comes to 109.0% of inseam from the pedal, and Peveler et al. (2005) found LeMond's method put 19 trained cyclists at 109.2%, give or take 0.9%.

Why no frame dimension comes from a picture. A measurement taken off a drawing is used here only when the drawing's scale, set by the 48.8-inch wheelbase, reproduces at least three other printed dimensions within 3.5%.

What was measured Eahora prints Measured Gap
Size drawing: total length 72.05 in 71.28 in −1.1%
Size drawing: handlebar height 42.5 in 45.99 in +8.2%
Size drawing: reach 22.8 in 16.61 in −27.1%

Side photograph: chain stay 18.9 in 19.27 in +2.0%

Both images are Eahora's own from its Luna page, scaled to the printed 48.8-inch wheelbase. The drawing reproduces one of five dimensions within 3.5% and the photograph two of three, so neither is used for a measurement.

The motor: 1,000 W in the rear hub, a twist throttle and five assist levels

Eahora rates the Luna's geared rear hub at 1,000 W with 1,500 W peak and 90 N·m of torque, and a twist throttle can drive it alone. Its specification page describes five pedal-assist levels "with Cadence Sensor" and a "5 Levels twist" throttle with a "slightly delayed response (safe design)".

Cruise control holds the speed after eight seconds on the throttle ("8 Seconds Auto-Cruise", per the product page's Riding Modes tab), and a walk mode pushes at 6 km/h, about 3.7 mph, for hills you climb on foot (specification page).

The owner manual's Luna page lists a "48V 25A Controller" and gives the torque as "80 -90N/M". The brakes carry a motor cutoff, so squeezing a lever cuts the drive.

Seven gears work the pedals, never the hub. The drivetrain is Shimano: a 7-speed 14–28T freewheel behind a 44-tooth chainring on 170 mm cranks (specification page). The range section shows what pedaling adds.

Eahora's close-up of the drivetrain, from its Luna page, scaled evenly: seven cogs from 14 to 28 teeth, by its specification page.

The battery and charging: 48 V, 15 Ah, 720 Wh

A 48 V, 15 Ah pack of lithium-ion pouch cells holds 720 Wh, rated by Eahora for at least 1,200 charge cycles before it falls to 80% of its capacity. You can lift the pack off, and it locks with a key; the package list counts "Ebike Battery * 1 (2 keys)" (Eahora's Luna page). Our battery types guide compares pouch cells with the cylindrical 18650 and 21700 formats.

Close-up of the Eahora Luna's battery on the down tube, with its keyed lock at the top and the JOPAJOCA wordmark on the tube beside it

Cropped from Eahora's side photograph: the 720 Wh pack sits on the down tube under a keyed lock, and the tube carries the JOPAJOCA name.

Eahora's FAQ on its Luna page says the battery "typically requires 7-8 hours to fully charge" on the included 48 V, 2 A charger, on the bike or off it. Arithmetic agrees: 720 Wh at 2 amps into a 48-volt pack is 7.5 hours from empty. The manual's charging section says "approximately 4-6 hours if the battery is mostly empty"; plan on the longer figure.

For storage, the manual advises keeping the pack "charged at about 75% capacity" over long breaks. A spare Luna and Terra battery pack is among the Luna parts in our Eahora parts collection.

A full charge costs about 13 cents of electricity, before charger losses, at the 18.16 cents per kilowatt-hour the US Energy Information Administration reports as the August 2026 residential average (EIA Table 5.6.A). Ridden 1,000 miles a year at 15 mph on the throttle by a 180 lb rider on level pavement, it uses about $3.20 a year in electricity, before charger losses.

Range: a 180 lb rider on the throttle at 15 mph computes to 41 miles

On level pavement at 77 °F, a 180 lb rider holding 15 mph on the throttle alone empties the Luna's 720 Wh pack in 41 miles, or 31 miles with a quarter kept in reserve. Eahora rates 35 to 45 miles without pedal assist and 44 to 58 with it (specification page); the tables map both to speeds.

Every figure in this section is computed from published physics and Eahora's own numbers. Find your ride in three steps:

  1. Pick your speed and effort in the speed tables.
  2. Adjust for your hills, your weight and the cold in hills, weight and cold.
  3. Plan on the column with a quarter kept so a reserve stays in the pack.

Does riding faster cut range?

Yes, steeply: at 20 mph the same 180 lb rider on the throttle covers 29 miles on level pavement, 12 fewer than at 15 mph, because air drag grows with the square of speed.

Speed, flat Per mile Full charge With 25% kept
10 mph 12.7 Wh 57 mi 43 mi
12 mph 14.4 Wh 50 mi 38 mi
15 mph 17.6 Wh 41 mi 31 mi
18 mph 21.8 Wh 33 mi 25 mi
20 mph 25.2 Wh 29 mi 21 mi
25 mph 36.3 Wh 20 mi 15 mi
28 mph 46.0 Wh 16 mi 12 mi

Throttle only, a 180 lb rider plus load on the 91 lb bike, level pavement, 77 °F, tires at the median rolling resistance of ten measured fat tires; the last column keeps 25% of the pack.

Your pedaling stretches it. The table below holds the same rider and conditions and adds the rider's own power, 75 watts for easy pedaling and 150 watts for steady work.

Speed, flat Throttle only Easy pedaling (75 W) Steady pedaling (150 W)
15 mph 41 mi 64 mi 130 mi
18 mph 33 mi 44 mi 64 mi
20 mph 29 mi 36 mi 47 mi
25 mph 20 mi 23 mi 26 mi
28 mph 16 mi 18 mi 20 mi

A 180 lb rider plus load, level pavement, 77 °F; the motor makes up whatever the rider's watts do not.

With the motor off, the model puts 75 watts of pedaling at 8.8 mph on level pavement and 150 watts at 12.9 mph, so an empty pack still leaves you riding home under your own power.

What gear saves battery?

On a hub motor the gears set your legs' cadence and leave the motor alone, so no gear saves battery by itself; your own watts do. The hub turns with the wheel at every speed, and the table shows the motor's draw per mile with and without the rider's effort.

Your ride Throttle only Easy pedaling (75 W) Steady pedaling (150 W)
15 mph, flat 17.6 Wh 11.3 Wh 5.5 Wh
20 mph, flat 25.2 Wh 20.1 Wh 15.4 Wh
12 mph, 4% grade 50.1 Wh 38.4 Wh 28.1 Wh
12 mph, 8% grade 105.7 Wh 86.9 Wh 70.7 Wh

Watt-hours drawn from the pack per mile, a 180 lb rider plus load at 77 °F; the climbs run at 12 mph.

Shift to whatever gear keeps your legs turning comfortably at your speed; the 75-watt column prices that easy effort.

Does going uphill drain it faster?

Much faster: holding 10 mph up a steady 6% grade on the throttle, a 180 lb rider covers 10 miles on a charge, and on 10% it falls to 5.

Grade Per mile, throttle Full charge, throttle Full charge, easy pedaling
2% 29 Wh 25 mi 41 mi
4% 49 Wh 15 mi 21 mi
6% 75 Wh 10 mi 13 mi
8% 106 Wh 7 mi 9 mi
10% 148 Wh 5 mi 6 mi
12% 204 Wh 4 mi 4 mi
15% 353 Wh 2 mi 3 mi

At 10 mph, a 180 lb rider plus load, 77 °F, on a constant paved grade; easy pedaling adds 75 watts.

Each 1,000 feet of climbing at 10 mph on the throttle costs about 174 Wh more than the same distance on the flat on a 4% grade, 196 Wh more on 6%, 223 on 8% and 257 on 10%.

The controller sets a ceiling too. Holding 10 mph on a 10% grade, the model draws 1,235 W from the pack, which is 25.7 amps at 48 V, just past the 25 A the manual lists for the Luna's controller; 12% asks 32.3 A and 15% asks 43.4 A, so pedal with it on the steep pitches.

Does rider weight affect range?

Yes: from a 130 lb rider to a 300 lb rider plus load, the 15 mph throttle range on level pavement falls from 44 miles to 34. Climbing magnifies the gap.

You plus your load 15 mph flat, throttle 20 mph flat, throttle 8% climb, 10 mph
100 lb 47 mi 32 mi 11 mi
130 lb 44 mi 30 mi 9 mi
180 lb 41 mi 29 mi 7 mi
220 lb 38 mi 27 mi 5 mi
260 lb 36 mi 26 mi 4 mi
300 lb 34 mi 25 mi 3 mi
330 lb 33 mi 24 mi 3 mi

Throttle only, level pavement or a steady 8% grade at 10 mph, 77 °F; each row is the rider plus anything carried, up to the 330 lb Eahora allows.

The manual sets "The recommended loading is 300lbs" beside the 330 lb maximum, and the 300 lb row is printed for that reason.

Does cold weather drain it?

Yes: at 32 °F the 180 lb, 15 mph, flat throttle ride drops to about 32 miles, and at 14 °F to about 29, against 41 at 77 °F.

Air Pack energy vs 77 °F 15 mph flat, throttle

Cells at air temperature, a 180 lb rider plus load, 15 mph on the throttle, level pavement; the bracketed figures span the cell data read for cold, and colder air and stiffer tires add drag.

In winter, keep the pack in the house between rides and clip it on at the door, so the cells leave warm.

Do the tires cut range?

The tires move the 15 mph flat figure from 48 miles to 38 across the spread of ten measured fat tires. Eahora names the CST BFT in 20 × 4.0, a tire those drum tests do not include, so the model uses the middle of that spread.

Rolling resistance 15 mph flat, throttle 20 mph flat, throttle
0.0070 · the lowest of ten fat tires 48 mi 32 mi
0.0105 · the median of ten fat tires (used) 41 mi 29 mi
0.0126 · the highest of ten fat tires 38 mi 27 mi

Throttle only, a 180 lb rider plus load, level pavement, 77 °F; rolling resistance from drum tests of ten 26 × 4.00 fat tires at 12 psi.

Keep your tires inside the 28 to 33 psi Eahora prints.

Is Eahora's range real?

The model finds a steady speed behind each of Eahora's range figures. Its 35 to 45 miles "w/o PAS" is a 180 lb rider holding 17.2 to 13.7 mph on the throttle over level pavement; its 44 to 58 miles with assist fits a rider who pedals easily at 18 to 15.7 mph.

Eahora's figure Per mile Motor only Easy (75 W) Steady (150 W)
58 mi, assist (spec block) 12.4 Wh 9.7 mph 15.7 mph 18.6 mph
44 mi, assist (spec block) 16.4 Wh 14 mph 18 mph 20.5 mph
45 mi, throttle (spec block) 16.0 Wh 13.7 mph 17.8 mph 20.4 mph
35 mi, throttle (spec block) 20.6 Wh 17.2 mph 20.3 mph 22.4 mph
25 mi, mode not printed (headline) 28.8 Wh 21.9 mph 24 mph 25.6 mph

Each Eahora figure is turned into the steady speed that would produce it on level pavement for a 180 lb rider plus load at 77 °F, on the motor alone and with 75 or 150 watts of pedaling.

The headline strip's "25 - 45 MILES" names no mode; its low end matches the motor alone at about 22 mph.

Plan on 31 miles at 15 mph on the throttle with a quarter of the pack kept, for a 180 lb rider on level pavement. Hills, cold and a heavier load cut it; steady pedaling stretches it.

How the range figures are computed

Power at the wheel = speed × [mass × gravity × (rolling resistance × cos θ + sin θ) + ½ × air density × drag area × speed²], the road model Martin et al. (1998) validated on the road. The model divides that power through the motor's and the battery's efficiency and reports the watt-hours each mile draws from the pack.

Input Value Source
Bike 91 lb with the battery Eahora's specification page
Pack 720 Wh, 48 V × 15 Ah Eahora's specification page
Motor 1,000 W rated, 33 mph top; a comparable 48 V hub's curve at its 80% efficiency floor Eahora; Bafang's OEM workbook (2021)
Rolling resistance 0.0105, the median of ten fat tires (0.0070 to 0.0126) Bicycle Rolling Resistance
Drag area 0.640 m², upright riders Tengattini and Bigazzi (2018)
Air density 1.184 kg/m³ at 77 °F US Standard Atmosphere (1976)
Battery efficiency Measured on a 48 V pack Arango, Lopez and Ceren (2021)
Reserve 25% kept Schmitt, Decker and Doppelbauer (2019)
Cold Energy by temperature, LG HG2 cell Kollmeyer's LG HG2 data

Eahora's figures read November 10, 2026; the studies as cited.

One ride, worked through: a 180 lb rider at 15 mph on the throttle, on level pavement at 77 °F. Rider and bike weigh 271 lb, or 122.9 kg. Of the 199.4 W the wheel needs, the tires take 85.2 W and the air 114.2 W.

The motor turns that into a draw at 78.12% efficiency and the battery delivers it at 96.54%, so the pack gives up 264.4 W. At 15 mph that is 264.4 ÷ 15 = 17.63 Wh per mile, and 720 Wh ÷ 17.63 = 40.84 miles; with a quarter kept, 30.63 miles.

The road model reproduces the worked example in Martin's Appendix I to the tenth of a watt, 45.7 W for rolling and climbing and 158.8 W of drag; Limitations lists what else the chain rests on.

Brakes: two-piston hydraulic calipers on 180 mm rotors

Both wheels stop on hydraulic discs, 180 mm across and 2.3 mm thick, squeezed by two-piston calipers with semi-metallic pads, and each lever cuts the motor. That is how Eahora's specification page lists them: "Hydraulic disc brakes with motor cutoff".

Close-up of an Eahora Luna disc brake: a slotted steel rotor stamped 180 bolted to the rear hub, beside the axle nut and the frame dropout

Eahora's brake close-up, scaled evenly: the rotor carries its 180 mm size stamped on it.

With the cutoff, either lever you pull stops the motor. Eahora fits the step-over Terra with four-piston calipers on the same rotor size (its specification page), the one brake difference between the two bikes; our Terra review covers that bike.

Suspension and tires: coil springs at both ends on 4-inch rubber

An 80 mm coil fork in front and a four-bar-link rear end on a 50 mm coil shock, on CST BFT tires 20 inches across and 4 inches wide. Eahora lists all four on its specification page, with the tires "with tube (28-33 psi)".

Close-up of the Eahora Luna's rear suspension: a red linkage plate on pivots above a black coil shock, with a red seat clamp and a moon logo on the seat tube

Eahora's suspension close-up, scaled evenly: the red linkage works the 50 mm coil shock below the saddle.

The rear shock sits under the saddle, worked by the red linkage in Eahora's photographs, so the whole rear triangle swings on pivots. Our suspension guide explains what electric bike suspension actually is. The product page calls the tires "All-Terrain Tires" with an "anti-puncture design" (Eahora's Luna page); the rims are 36-hole aluminum with stainless spokes.

Lights, horn, rack and display

A 1,500-lumen, 15 W LED headlight with a built-in electric horn, a tail light with an integrated brake signal, a rear rack, front and rear fenders and a 4-inch color display with a USB charge port all come with the bike. Eahora names each on its specification page.

Eahora's headlight close-up, scaled evenly; Eahora rates the light at 1,500 lumens and 15 W, with the horn built in.

The tail light rides on the rack, Eahora's own "Customized rear rack" (specification page); ask us what it carries before you plan heavy loads on it. Eahora's own rear bags and basket made for the Luna are in our Eahora accessories collection.

The display shows speed, battery level and mileage, by the product page's description, and the saddle is a "Leather wide seat with memory foam" on an aluminum post with a 38.1 mm clamp.

The Mercer fit test

Every Redtail review holds the bike against the same seven people, the Mercers and the Kowalskis, our editorial cast, and reads each verdict from a published number, a row of the fit model or a statute. For the Luna, the seat height and the law decide most rows.

Member Verdict The number behind it
Frank Kowalski, 63, 5'10" Fits; no top tube to swing a leg over Inside Eahora's 5'4" to 6'1" window; 94 of 100 riders at 5'10" sit flat-footed at the 32.3 in lowest seat
Ruth Kowalski, 61, 5'5" Fits the frame; slides forward at stops Inside the window; 10 of 100 riders at 5'5" reach the ground seated, and all 100 clear the 24.2 in standover
Jack Mercer, 48, 6'1" At the very top of the window 6'1" ends the page's window and sits inside the manual's 5'4" to 6'2"; his saddle top comes 32.1 in above the crank axle
Dana Mercer, 45, 5'7" Fits; rider plus cargo up to 330 lb Inside the window; 45 of 100 riders at 5'7" sit flat-footed at the lowest seat, with 300 lb the manual's recommended loading
Maya Torres, 32, 5'6" Fits; her state decides the commute 27 of 100 riders at 5'6" reach the ground seated; 41 miles at 15 mph on the throttle, 180 lb, level, computed
Cole Mercer, 16, 5'11" Not as an e-bike Outside the e-bike definition in 49 jurisdictions, the Luna falls under his state's rules for another vehicle class, with that class's own age and license rules (state law table)
Ivy Mercer, 12 No The same vehicle-class line applies at 12; we do not recommend it for her

Ages from the Mercers' profile, heights as each member is cast; shares from this page's fit model on ANSUR II bodies; windows and loads from Eahora's Luna page and owner manual.

Ruth and Jack bracket the window. At 5'5", Ruth clears the frame with 6.8 inches to spare at the median, yet only 10 riders in 100 her height touch down from the saddle, so she stops by sliding forward. At 6'1", all 100 riders his height sit flat-footed, but he stands at the top of Eahora's printed window; our tall-rider guide sorts bikes band by band from 6'0" to 6'8".

Is the Eahora Luna UL certified?

A building manager, landlord or city asking for a certificate? Tell us, and we will write to Eahora for it. Eahora's site-wide FAQ says its batteries "are fully compliant with the rigorous UL certification standards" (Eahora's FAQ); for the Luna itself, the specification page prints water ratings, IP65 for the bike and IPX6 for the motor.

UL 2849 is "the Standard for Electrical Systems for eBikes", and UL Solutions certifies to it "by examining the electrical drive train, battery, and charger system combinations in e-bikes", so a certificate names the model and the standard together. Ask for yours by the name Luna.

Has the Eahora Luna been recalled?

No. On November 10, 2026, no recall and no public safety warning in the US Consumer Product Safety Commission's records named Eahora or either Luna SKU. We read every one of its 10,082 recall records, its 382 public safety warnings and its recall feed.

Check Result, November 10, 2026
CPSC recalls, all 10,082, for Eahora or the Luna's SKUs ZD1055 and ZD1056 None found
CPSC public safety warnings, all 382, for the same None found
CPSC recall feed, October 8 to November 5, 2026 None found

Read through the CPSC's own recall service and files on November 10, 2026; the newest recall in the service is dated November 5. The same reads found the recalls naming Ancheer and Specialized, two makers with records in the service, so the empty result is a real one.

Is the Eahora Luna street legal? 1,000 W, 28–33 mph and your state

The Luna's published 1,000 W and 28 to 33 mph (Eahora's specification page) exceed both limits of the federal "low-speed electric bicycle": "an electric motor of less than 750 watts (1 h.p.), whose maximum speed on a paved level surface, when powered solely by such a motor while ridden by an operator who weighs 170 pounds, is less than 20 mph" (15 U.S.C. § 2085).

Riding rules are set state by state, so the screen below runs Eahora's 1,000 W rating, the top of its speed range at 33 mph, a twist throttle and 91 lb (specification page) against each jurisdiction's own definition:

Outcome Jurisdictions Count
Qualifies as an electric bicycle none 0
Outside the state's e-bike definition AL, AR, AZ, CA, CO, CT, DC, DE, FL, GA, HI, IA, ID, IL, IN, KS, LA, MA, MD, ME, MI, MN, MO, MS, MT, NC, ND, NE, NH, NJ, NM, NV, NY, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VA, VT, WA, WI, WV, WY 49
No statutory e-bike definition AK, KY 2

Each jurisdiction's own statutory definition, applied on November 10, 2026, to Eahora's rated 1,000 W and the 33 mph top of its printed range. A reading of the statutes, not legal advice; your state's motor vehicle office applies them.

California shows the watt line most plainly: an "electric bicycle" there has "an electric motor that does not exceed 750 watts of power" (California Vehicle Code § 312.5), and our California page walks through the classes.

New Jersey reads the throttle: under P.L.2025, c.285, a low-speed electric bicycle's motor "provides assistance only when the rider is pedaling" (our New Jersey page). Our 1000W guide asks which states allow a 1,000 W electric bike and how fast one goes.

Falling outside the definition changes what the rider needs. Florida's e-bike exemption reaches only a machine inside it: "An electric bicycle or an operator of an electric bicycle is not subject to the provisions of law relating to financial responsibility, driver or motor vehicle licenses, vehicle registration" (Fla. Stat. § 316.20655).

A bike outside it is the vehicle the code's other chapters name, with their license and registration rules; our Florida page and our Texas page set out what each state asks.

Off the road, the land manager decides, and federal land carries federal penalties; our electric mountain bike guide starts from the spec that decides where you can ride. On National Forest System land a "Motor vehicle" is "Any vehicle which is self-propelled, other than" a rail vehicle or a mobility device (36 CFR § 212.1), the Luna included.

On Bureau of Land Management (BLM) land an e-bike has "an electric motor of not more than 750 watts (1 h.p.)" (43 CFR § 8340.0-5(j)), so a 1,000 W Luna rides there as an off-road vehicle, "any motorized vehicle capable of, or designed for, travel on or immediately over land" (§ 8340.0-5(a)).

On federal land Where the Luna may go If it goes where the rules close it
National Forest System Roads, trails and areas the forest's motor vehicle use map opens to motor vehicles (36 CFR § 261.13) Unless another law says otherwise, "imprisonment of not more than six months or a fine in accordance with the applicable provisions of 18 U.S.C. 3571 or both" (36 CFR § 261.1b)
BLM Areas and trails "designated as open to off-road vehicle use", under your state's off-road vehicle rules (43 CFR § 8341.1) "a fine of not more than $1,000 or imprisonment for not longer than 12 months, or both" (43 CFR § 8340.0-7)

The federal regulations as published in the eCFR, read November 10, 2026. The penalty in § 8340.0-7 reaches the rules of its own subparts, 8341 and 8343.

Start with your state's entry in our law table, then ask that state's motor vehicle office how it classes a 1,000 W, 33 mph bike; on federal land, the answer is on the forest's motor vehicle use map, or in the BLM area's designation. Our public-land guide covers both, and private land rides by the owner's rules.

On Eahora's published figures the Luna falls outside the e-bike definition in 49 jurisdictions and meets no definition in Alaska or Kentucky, which have none. Your state's vehicle class sets the license and registration on public roads, forest and BLM managers set the open routes on their land, and a private landowner sets the rest.

Read your state's rule, then order the Luna at Eahora's own price, $799. Questions about where you plan to ride come to us by email, and our reply cites the code.

Green flags / Red flags

The Luna's strengths, from Eahora's figures and our models, then the riders it fits less well and where you should look if you are one of them.

Green flags

  • Full coil suspension, hydraulic brakes and a twist throttle on a step-through for $799, Eahora's own US price (what it is).
  • 41 miles at 15 mph on the throttle for a 180 lb rider on level pavement, computed from the 720 Wh pack (range).
  • 1,000 W rated, 1,500 W peak and 90 N·m, with five assist levels and cruise control (motor).
  • Every height from 5'0" clears the 24.2-inch standover Eahora prints (fit).
  • Lights, a horn, a rack and fenders come with the bike (lights).
  • No CPSC recall or warning names Eahora or the Luna's SKUs, read November 10, 2026 (recalls).

Red flags

  • A bike you can ride wherever e-bikes go. At 1,000 W and 28 to 33 mph the Luna sits outside the definition in 49 jurisdictions (where to ride); our under-$1,000 guide sorts its seven picks by that line, and one sits under both federal numbers as shipped.
  • Both feet down from the saddle below about 5'8". Only 10 of 100 riders at 5'5" touch down seated at the lowest setting; the three-wheel picks in our electric bikes for seniors guide stand up on their own at a stop.
  • A rider over 6'1". Eahora's page window stops there; our tall-rider guide names picks up to 6'8".
  • A rider set on four-piston brakes. The Luna's calipers carry two pistons; the Terra puts four on the same 180 mm rotors for $100 more.
  • Rides past 31 miles between charges. That is the 15 mph planning figure with a quarter kept; the Luna II carries 960 Wh on the same frame, and our long-range guide has eight picks.
  • Stairs or a car rack. The bike weighs 91 lb with its pack; if it has to climb stairs or ride a car rack, email support@redtailebikes.com and we will suggest something lighter that we sell; our commuter guide has a lightweight row for bikes carried up stairs.

Buy it if / Buy something else if

Buy the Luna if you want full suspension on a step-through for under $800, you ride where a 1,000 W, 33 mph machine is allowed, and you are between 5'4" and 6'1". On our model it runs 41 miles at 15 mph on the throttle with a 180 lb rider on level pavement, and 1,000 miles a year costs about $3.20 in electricity before charger losses.

Buy something else if your rides must stay inside your state's e-bike definition (our under-$1,000 guide), you want a top tube or four-piston calipers (the Terra), or you want more range on this frame (the Luna II); or answer a few questions in our e-bike finder, which matches 128 bikes to your body and town. For the Luna itself, our listing carries the price and the colorway.

Before you buy: the checklist

Seven checks in the order they come up: your state, your trails, your inseam, your stops, your load, your hills and the first ride. Our buying guide has the seven-spec checklist for any e-bike.

  1. Look up your state in our law table and note which vehicle class a 1,000 W, 33 mph bike lands in.
  2. Check the trails you plan to ride against their land manager's rules, using our public-land guide.
  3. Take your inseam and match it to a row of the saddle table.
  4. Decide how you will stop: seated or standing over the frame, from the seat table.
  5. Add up rider and cargo against 330 lb, with 300 lb the manual's recommendation.
  6. Find your steepest hill in the climb table.
  7. On delivery, check both axles and the bars for play, set the tires inside 28 to 33 psi and set the saddle with the heel check; our maintenance guide lists the first 30 days' checks.

Frequently asked questions

Not as an e-bike in 49 of the 51 US jurisdictions on November 10, 2026; Alaska and Kentucky have no definition to meet. Its published 1,000 W and 28 to 33 mph (Eahora's specification page) sit outside the definition in each of the others, so your state treats it as another class of vehicle, with that class's license and registration rules; see where to ride and your state's page.

How fast does the Eahora Luna go?

Eahora prints 28 to 33 mph "for both pedal-assist and throttle" (its specification page). On level pavement with a 180 lb rider, the range model puts the throttle's top steady speed at 28.1 mph, and holding 28 mph empties the pack in about 16 miles.

Is 28 mph fast for an e-bike?

It is the top of the three-class system: California's Class 3 assist stops "when the bicycle reaches the speed of 28 miles per hour" (California Vehicle Code § 312.5), and a Class 3 motor there "provides assistance only when the rider is pedaling". The Luna's throttle reaches the same speeds, which is one reason it falls outside the definitions.

How far can the Eahora Luna go on one charge?

For a 180 lb rider on level pavement at 77 °F, the throttle alone gives 41 miles at 15 mph, 29 at 20 mph and 16 at 28 mph; easy pedaling at 15 mph stretches it to 64 miles. With a quarter of the pack held back, 31 miles at 15 mph is the figure to plan around. Eahora rates 44 to 58 miles with pedal assist and 35 to 45 without (its specification page; range).

What rider height fits the Eahora Luna?

Eahora lists 5'4" to 6'1" with an inseam of 26.8 inches or more (specification page), and its manual 5'4" to 6'2". A 5'8" rider with the survey's median 32.64-inch inseam sets the saddle top 28.9 inches above the crank axle by the 109% formula, and from 5'0" every height clears the 24.2-inch standover (fit).

What is the difference between the Eahora Luna and the Luna II?

The Luna has one 1,000 W rear hub and a 720 Wh pack (its specification page); the Luna II has two 500 W hubs and a 960 Wh pack, with the same high-carbon steel 20 × 15 in frame on Eahora's Luna II page. Ours are $799 and $999. Our Luna II review runs its numbers.

Eahora Luna or Terra: which should I buy?

Choose by frame and brakes. The Luna is a step-through with two-piston calipers at $799; the Terra is a step-over with four-piston calipers at $899. Eahora's two specification pages print the same motor, pack, speed, suspension and 91 lb weight (Luna, Terra); see our Terra review.

Is a step-through e-bike only for women?

No. "Step-through" describes the missing top tube, nothing about the rider, and Eahora fits the Luna to riders from 5'4" to 6'1", the same window it prints for the step-over Terra (Eahora's Luna page).

Are step-through electric bikes good for seniors?

The frame is the easy part: every height from 5'0" clears the Luna's 24.2-inch standover (Eahora's size table). The seat is the harder one, because at its lowest it sits 32.3 inches up and only 10 of 100 riders at 5'5" touch down while seated. Our electric bikes for seniors guide puts that seated stop first, with three-wheel picks for riders it unsettles.

What does full suspension mean on a bike?

Springs at both wheels. The Luna has an 80 mm coil fork in front and a four-bar-link rear end on a 50 mm coil shock (specification page), so both wheels can move up over bumps instead of passing every hit to the frame.

How long does the Eahora Luna take to charge?

Eahora's FAQ on its Luna page says "7-8 hours" on the included 48 V, 2 A charger, and 720 Wh at 2 A into 48 V works out to 7.5 hours from empty. The manual's charging section gives "approximately 4-6 hours if the battery is mostly empty". The pack comes off the bike, so it can charge indoors.

Is the Eahora Luna's battery UL certified?

Eahora's FAQ says its batteries "are fully compliant with the rigorous UL certification standards"; the Luna's specification page prints water ratings, IP65 for the bike and IPX6 for the motor. If a building or city needs papers, email us and we will request them from Eahora (UL).

What tire pressure does the Eahora Luna use?

Eahora prints 28 to 33 psi for the CST BFT 20 × 4.0 in tires, which run tubes (specification page). The tire table prices that spread in miles.

How much does the Eahora Luna weigh?

91 lb with the battery installed, by Eahora's specification page, and it carries up to 330 lb of rider and cargo, with 300 lb recommended in the manual.

Does the Eahora Luna have cruise control?

Yes. The product page's Riding Modes tab lists "8 Seconds Auto-Cruise", so holding the throttle steady for eight seconds sets the speed, beside five assist levels, a five-level throttle and a 6 km/h walk mode (motor).

Limitations of this review

Every number above traces to a named source or to a model that shows its inputs; the list below is where each one stops being exact for the Luna.

  1. We sell the Luna. Each source is linked so you can check it yourself.
  2. The range model holds one steady speed with no stops, wind or traffic, on flat pavement or a single constant paved grade per row.
  3. The motor's losses are a comparable motor's. Eahora names no motor maker and prints no efficiency for the Luna's hub, so the model uses a published 48 V hub curve at its 80% efficiency floor, scaled to Eahora's 1,000 W rating and 33 mph top.
  4. The wheel diameter is borrowed. Eahora prints a 16.4-inch rim and no outer diameter, so the model takes Samebike's printed 22.8 inches for a 20 × 4.0 wheel; it sets only the torque a climb needs.
  5. The tires are bracketed, not measured: ten 26 × 4.00 fat tires measured on a drum at 12 psi stand in for the CST BFT 20 × 4.0, which those tests do not include.
  6. Cold is modeled with the cells at air temperature, using one cell type's measured data and a bracket from others, because Eahora names pouch cells but no cell model.
  7. The 25% reserve is borrowed from a measured pedelec that delivered 75% of its nominal pack; Eahora prints storage advice but no planning reserve.
  8. No measured ride to empty for the Luna, with its rider's weight and speed printed, appears in the record we read, so the model's whole-bike cross-check is its mapping to Eahora's own figures.
  9. ANSUR II measured soldiers: the fit model's 6,068 bodies come from the US Army, and the general public may differ.
  10. The formula only starts the saddle height; the heel check on the bike finishes it.
  11. Lean and hand load are not computed, because Eahora publishes no grip position for the Luna.
  12. Eahora prints the step-over Terra's whole size table for the Luna, the 24.2-inch standover included. Neither Eahora's drawing nor its side photograph reproduced enough printed dimensions to measure the frame, so every fit table uses Eahora's figures as printed.
  13. Eahora prints some figures two ways: the range strip and the specification page, the rider window on the page and in the manual, the torque, the handlebar height, the charging time and the frame material. Each pair is shown where it decides something.
  14. The owner manual covers four models, the Luna, Luna II, Terra and Terra II; it is quoted only where its Luna page or a section for all four prints the figure.
  15. No load rating is printed for the rear rack.
  16. No certification document was retrieved for this page. We can ask Eahora for one on your behalf if a building, landlord or city wants the paper.
  17. The law screen applies each jurisdiction's statutory definition to Eahora's published figures as of November 10, 2026; it is not legal advice, and a state can amend its code.
  18. What we read on November 10, 2026, can change: prices, Eahora's pages, our policies and our checkout.

The bottom line

The Luna is Eahora's full-suspension step-through: a 1,000 W rear hub, a 720 Wh pack, coil springs at both wheels and hydraulic brakes for $799. For a 180 lb rider holding 15 mph on the throttle over level ground, the model gives 41 miles a charge, on roughly 13 cents of electricity per full pack.

Buy it if you ride on private land or under your state's rules for a 1,000 W, 33 mph vehicle, and you stand between 5'4" and 6'1". Riders who must stay inside their state's e-bike definition should open our under-$1,000 guide first; riders who want a top tube and four-piston calipers, the Terra.

Order at Eahora's own price, $799, with free shipping within the contiguous United States. Email support@redtailebikes.com your height, your steepest hill and your state before you order, and we will answer with your numbers.
