Addmotor Citytri E-310 Review: 750W, Folds, Ridden

This Addmotor Citytri E-310 review covers a folding electric trike, which is a rarer thing than it sounds: three wheels solve the balance problem, and then the trike will not fit through your door. This one folds. We sell both frames for $1,699 with free shipping in the lower 48, which on the taller Plus frame is $100 under Addmotor's own price — and we rode it off pavement before writing this.

750 W rear hub · 960 Wh UL-certified · 20 mph · 90 mi claimed · 360 lb load · folds · 86 lb · $1,699

Specifications verified: September 19, 2026, against Addmotor's US product page, its own technical post, our storefront record and the federal recall database.

The short version

Quick Answer — The Addmotor Citytri E-310 is a $1,699 folding electric trike: 750 W rear hub, 960 Wh battery certified to UL 2271 and UL 2849, a rear differential, a parking brake, 20 mph. It weighs 86 lb and the Standard folds to 45 × 34 × 29 inches. Buy it if you want three wheels and must store it indoors.

It comes in two frame sizes at the same price: Standard for riders 5'1"–5'9", Plus for 5'3"–6'1". Addmotor rates it to carry 280 lb of rider plus 80 lb of cargo. It is a single-speed, so it is built to cruise with power on tap rather than to be pedaled hard — the reason is in the motor section.

Buy Blue Standard — $1,699 · Buy Blue Plus — $1,699 — free shipping in the lower 48. Standard fits 5'1"–5'9", Plus fits 5'3"–6'1"; pick your frame first.

A folding trike with a certified 960 Wh pack, at $1,699.

We rode it off pavement

Reviews of this trike are generally written from a specification sheet. Ours is too, for every number below — Addmotor's figures, read on the date at the top. But the machine was also ridden, off pavement, and the footage is published rather than described.

A ride settles something a specification sheet cannot, and on a folding trike the question is whether the hinge holds. A trike that folds has a joint in the middle of the frame and a differential hanging off the back, and both are places a machine can feel vague.

It holds. Ridden hard by a 220 lb rider at 6'1" — off pavement, treated more like a mountain bike than a shopping trike, the folding joint produced no creak, no knock and nothing working loose. The common worry about a folding trike is that it will fold when you do not want it to. This one gives no sign of it.

What the footage actually is. The published four minutes is the ride back. The first attempt went into bush rather than onto a trail, thick enough that there was no seeing what was ahead, so it was turned around — and the camera was started at the turn. What you are watching is the return leg out.

Three other things the ride settled:

• The weight is the first thing you notice, before you ride it at all. The frame came out of the shipping box one-armed, which is the frame in the box and not the assembled 86 lb machine, but it sets the tone: this is a light trike, and the 2.4-inch tires and the small rear wheels are where the weight went.
• It reached its cap off pavement, about 20 mph, without drama. The torque is the character of it, and the closest thing it feels like is a go-kart.
• It did not get stuck in mud, dirt or snow on that ground, on the 2.4-inch tires our listing publishes.

Build quality, by eye: the paint is clean and the welds are tidy, with nothing flawed found yet. Addmotor builds the frame in 7020 and 6061 aluminum.

One control is worth knowing about. The unit we have carries an on/off switch for the throttle, and Addmotor describes the same capability in its own words, answering a customer question on its product page:

The E-310 "is a versatile hybrid featuring a 7-level PAS system and a throttle. You can choose to ride using throttle only or get some exercise with the PAS system. It can also be used as a trike with the power cut-off option."

What the maker publishes is the power cut-off; the switch we found on our unit is how it is operated. Set it where you want it before your first ride.

What the ride does not settle is range or top speed as measurements — for those, the figures on this page are Addmotor's, or the work of the outlet named beside them.

How we verified this Addmotor Citytri E-310 review

By Milad Ghobadibeygvand, BScN (Western University, 2014) — writer and reviewer, Redtail eBikes. Corrections: support@redtailebikes.com.

This review sits in our e-bike review index, and why buy from us sets out the terms behind every one of them.

Verification basis: ridden, and every specification confirmed at the manufacturer and recomputed. Addmotor's US product page, its UL certification post and our own listing were read on September 19, 2026. The recall check is a dated query against the CPSC database, run with a control so a silent zero could not pass for a clean one.

The full specification

Six of these figures sit in the headline strip on Addmotor's US page — motor, battery, certification, range, payload and top speed — and are marked below. The rest come from our own listing's specification table and Addmotor's technical post, all read September 19, 2026.

What the Citytri E-310 is

It is built for one problem, and it solves that problem better than anything else at the price.

The problem is this. Three wheels remove the balance requirement entirely: a trike stands up by itself, at a stop, on a hill, with shopping in the basket.

Riders move to them for exactly that reason, and it settles the "electric trike versus bike" question honestly: a bicycle is lighter and faster, while a trike is the one that stays upright. If you have not settled that question yet, start with our electric bike buying guide. Addmotor builds its whole trike range around that premise.

But a rigid trike is about five feet long and does not turn sideways, so it defeats apartment doorways, hatchbacks, RV bays and most garages that already contain a car. The Citytri folds. The fold is the whole argument, and everything else on the machine is competent-to-good at the price.

Addmotor builds other trikes that fold too, the Triketan M-330F among them, so the Citytri is not the only route to a folding trike — it is the cheapest of them on our shelf. Our guide to every electric trike we carry sets them side by side with what each one publishes.

Addmotor builds it in two frame sizes and charges $100 more for the larger one. We do not: both are $1,699 here, so the frame decision is about your body and your storage rather than your budget.

If you are still deciding between three wheels and two, our electric trikes collection is the whole shelf in one place, and the Addmotor range we stock sits beside it — this trike's own listing carries the full specification table.

Five of the six colorways Addmotor lists. Every one is the same $1,699 trike.

Standard or Plus?

It is the question the search suggestions fill in first, and the answer is short. The fit figures below are from our own listing's specification table.

Both frames are $1,699 from us, so price never decides this. If you are between 5'3" and 5'9" both fit you, and the decision is storage against comfort: the Standard folds about four inches shorter and nine inches lower, the Plus rides on larger wheels. Under 5'3", take the Standard — the 13.8-inch standover is the number that lets you step through rather than over. Over 5'9", take the Plus.

The published range holds up. Riding the Standard at 6'1" — four inches above the top of its stated range — it is tight, and the Plus is noticeably roomier. If a number on this page is going to decide something for you, let it be this one.

The saddle is sprung and comes with a backrest — part of why the trike suits a long, slow ride.

Measure the space first. The folded footprint is published for both frames precisely so you can, and a trike that does not fit the bay it was bought for is the one genuinely expensive mistake available here.

Not sure? Tell us your height and we will tell you which frame — support@redtailebikes.com. Our guide to electric bikes for adults sets out the fit numbers that decide it on two wheels as well as three.

750 watts, one gear

The motor is a 750 W rear-drive hub, as Addmotor's US page states. Addmotor's own technical post puts peak output at 1,400 W and torque at 90 N·m, and torque is the figure that matters on a machine that may be carrying 360 lb up a driveway.

There is one thing to understand before you buy, and it is a design choice rather than a fault: the Citytri is a single-speed. There is no cassette and no derailleur. Pedaling contributes at low speed and progressively less as the trike gains it — BikeRide's tester reports the pedals spinning without much purchase above roughly 10 mph. Above that, the throttle and the assist do the work.

In the other direction the torque is the whole personality of the machine: 90 N·m under an 86 lb trike pulls away from a stop like a go-kart, and no hill we pointed it at stopped it.

Read that as what the machine is for. It is geared to cruise at a calm pace with power on tap. If you want to pedal for exercise across the whole speed range, this is the wrong trike and a geared one is right — our buying guide to folding e-bikes covers those.

Seven assist levels run through a 25 A controller and a 5-inch display, with a half-twist throttle for starts — which on an 86 lb trike with a load is the control you will actually use pulling away from a stop sign.

The stem carries a quick-release clamp, with the cabling routed down the head tube.

Two Addmotor pages disagree on the motor. Addmotor's US page publishes 750 W, and so do the two other US URLs for this model, all three carrying addmotor.com/products/citytri as their canonical address.

A separate export page for the same SKU publishes 500 W and quotes range in kilometers. The US machine is the 750 W one, which is the figure on our listing and on this page. Both were read September 19, 2026, and InsideEVs reported 750 W at launch.

The differential, and why it matters

Drive one rear wheel only, as many electric trikes do, and the geometry fights you. Turn a corner and the driven wheel fights the undriven one, which is the wallowing, skating feeling that puts riders off trikes on a first outing.

The Citytri has a genuine rear differential, so both rear wheels are driven and each turns at its own speed through a corner — the same reason your car has one. Dirt Wheels, which rode the trike, singles out the differential for cornering.

On a folding trike this matters more than it sounds, because the fold and the differential compete for the same space at the back of the machine. The usual resolution is to delete the differential. Addmotor keeps it, and names it in its own technical post as a differential rear axle.

The rear end: a disc rotor on the wheel, and the cargo basket sitting over the axle.

Brakes, and the parking brake

Mechanical disc brakes on all three wheels, and a parking brake, per our listing's specification table.

Dirt Wheels, which rode it, calls the parking brake rare on electric trikes — and it is the component that matters most here.

The parking brake is the component riders tend to discover the value of late. An 86 lb trike with 80 lb of cargo in the basket, parked on any slope, wants to leave without you. A parking brake is what lets you load it at the curb, or stop on a hill and get off.

Mechanical discs need cable adjustment as the pads wear, which hydraulics largely do not. Budget a cable tension check into the first service and then annually. If you want hydraulics on three wheels, that is a different trike at a different price, and our electric trikes guide lists which of ours have them.

The front wheel: disc rotor, suspension fork and a full fender.

On visibility: if you ride at dusk, add a rear beacon at seat height. The lighting is integrated, with brake activation and turn signals, but a rear light mounted low on any trike sits below the eyeline of a driver in a tall vehicle. Every trike shares that geometry, and a $25 accessory closes it.

960 watt-hours, and the 90-mile claim

The pack is 48 V and 20 Ah, which multiplies to 960 Wh — a large battery at this price, and Addmotor names Samsung cells.

Addmotor claims up to 90 miles and states the condition: assist level 1. That is the honest way to publish a range figure and the least useful one for planning, because nobody rides a 750 W trike at level 1 the whole way.

Do the arithmetic yourself instead. 960 Wh divided by 90 miles is about 10.7 Wh per mile, a plausible figure for a light rider on flat ground at the lowest assist.

A loaded trike on rolling ground draws far more. At 25 Wh per mile the same pack returns about 38 miles; at 35 Wh per mile, about 27 miles. Plan on the middle of that spread, treat 90 as the ceiling rather than the expectation, and you will not be stranded. InsideEVs reported the same 960 Wh pack and 90-mile claim.

The pack is what you are actually buying at $1,699. Nine hundred and sixty watt-hours with a named cell supplier and a UL certification is the specification that lifts this trike above the $1,200 tier, more than the motor does.

And the pack is working against a light machine on narrow tires. The Citytri runs 20 × 2.4 in front and 18 × 2.4 in rear, rather than the four-inch fat tires most electric trikes carry, and a narrower tire on a lighter trike asks less of the battery for the same distance. That combination — big certified pack, modest rolling resistance, 86 lb — is where the value sits, more than in any single number on the specification sheet.

Eighty-six pounds, and the fold

Eighty-six pounds is the number to take seriously, and it is the figure our listing publishes, with the battery in. Eighty-six is what it weighs, and it goes in the bay at 45.3 × 33.9 × 28.7 inches on the Standard frame.

It is light for a trike, and heavy for anything you intend to lift. Folding does not change the weight; it changes the shape. The folded trike is a 45 × 34 × 29 inch object that still weighs 86 lb, which two people can lift into an SUV and one person generally cannot.

So the fold buys storage and transport-with-help, rather than portability. If you are loading it alone and regularly, take the battery out first — the single biggest weight you can remove without tools — and consider a ramp.

If lifting is the central problem rather than storage, a folding two-wheeler is the honest answer: our Eunorau META20 folds at 63.4 lb at the same $1,699. It gives up the third wheel, which may be the thing you came for.

The Mercer fit test

Seven riders, one trike. Every verdict reads a published number — the rider-height ranges on our listing, Addmotor's 280 lb rider rating and its 20 mph cap — and nothing else. These are archetypes used to make the numbers concrete; none of them is a tester.

Is it UL certified?

Yes, and to both standards that matter, which is not common at this price.

Addmotor's US page states UL 2271 and UL 2849 on its specification strip. The two are not interchangeable:

• UL 2271 is the battery-pack standard. It tests the pack.
• UL 2849 is the system standard. It tests the motor, controller, wiring, charger and pack as one electrical system.

A machine certified only to UL 2271 has a tested battery inside an untested system. This one claims both, and Addmotor publishes a post explaining the distinction itself. UL Solutions publishes the scope of UL 2849 for anyone who wants the standard rather than the summary.

Why care: New York City bans the sale of uncertified e-bikes and batteries under Local Law 39 of 2023, which turns on UL 2849 for the machine and UL 2271 for the pack, and a growing number of buildings and insurers ask for the same. If you live somewhere with a rule, this is the specification you are being asked about.

Has it been recalled?

No — no recall is on file. We ran five queries against the CPSC recall database on September 19, 2026 — two for Addmotor, one for Citytri, one for electric tricycles and one for e-trikes. All five returned nothing.

The same database, asked for bicycles that minute, returned 385 records — so the zero is the database answering rather than the search failing. The CPSC is the sole publisher of US recall records, so there is no second source to check it against.

That answer is about the recall database specifically. The CPSC also publishes public warnings, which are a separate list, and its warnings view would not return results to us on September 19, 2026 — not for Addmotor and not for a control term either, so we could not read it rather than reading it clean.

Recalls and warnings are published after this page is. Check SaferProducts.gov yourself before you buy, and register the trike with Addmotor so you are reachable if one is ever issued.

Where you may ride it

Three wheels do not put a trike outside the e-bike category, and the clearest federal statement of that sits in product-safety law. 15 U.S.C. § 2085 makes low-speed electric bicycles consumer products regulated by the CPSC under 16 CFR part 1512, and subsection (b) defines the term for the purposes of that section:

a two- or three-wheeled vehicle with fully operable pedals and 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.

Two things follow, and the second is the one that matters to you.

First, read the thresholds: both say "less than". The trike is rated 750 W and 20 mph, so it sits at those numbers rather than under them. The speed limb is a specific test — the machine's speed under motor power alone with a 170 lb rider — and nobody publishes that measurement, so no published figure settles which side of it this trike lands on.

Second, and more usefully: that section is about how a product is regulated and sold rather than about where you may ride. Road use is set by your state's vehicle code.

None of that is peculiar to this machine. Nearly every 750 W e-bike sold in the United States is in the same position, because makers build to the number the states publish rather than the number the federal text uses.

States write that limb two different ways, and the wording decides the answer for a machine rated at exactly 750 W. Where the code is inclusive, this trike is inside it: Georgia and North Carolina both write "no more than 750 watts", and Nevada and Wisconsin write theirs the same way.

Four states we have read write it the other way. Maine's § 101(22-B) is the one to read, because it is written for three wheels: an electric bicycle there is "a 2-wheel or 3-wheel bicycle with fully operable pedals and an electric motor of less than 750 watts". New York's § 102-c says "less than seven hundred fifty watts" and Illinois says "less than 750 watts".

Florida spells out what follows. Section 316.003(23) reads "less than 750 watts", and a machine at 750 or more falls outside the electric-bicycle definition entirely and becomes a motor vehicle or a motorcycle — with the registration, license and insurance requirements that real e-bikes are exempt from. If your state writes the limb that way, that paperwork is yours to carry before the first ride.

Read your own state's page before the first ride rather than after. In the states running the three-class system, a throttle that stops assisting at 20 mph is the Class 2 description.

What varies, and what to check locally:

• Whether a trike may use a bike lane or a multi-use path. Width is the usual constraint, set by the trail operator rather than the state.
• Minimum age for a throttle class. Two of the states we have read set one that reaches Class 2. Hawaii bars anyone under 16 from a Class 2 unless a parent or guardian is supervising, and Illinois sets 15 for Class 1 and Class 2 from January 1, 2027. Both pages quote the section.
• Passengers. The trike is rated for one rider plus 80 lb of cargo. A cargo rating is not a passenger rating.

Our state-by-state e-bike law pages carry the current rule for each state with the statute quoted. It is worth reading before the first ride rather than after.

Green flags / Who it is wrong for

The case for this trike is the fold, the differential and the certified pack. The case against it is the weight, the single gear and one missing control — and each of those points at a machine of ours that answers it.

Riding with somebody who needs to be on the same machine rather than a second one? That asks for a different shape of trike, and our Addmotor M-380 Tandem review covers the two-seat version with its own published payload and fit range.

Buy it if / Buy something else if

Buy it if you want the stability of three wheels and you have a storage or transport problem a rigid trike cannot solve — an apartment, an RV bay, a hatchback, a shared garage. That combination is the entire case, and at $1,699 with a 960 Wh certified pack, a differential and a parking brake, it is the folding trike we would put a buyer on.

The value case, in numbers. Addmotor sells the Standard at $1,699 and the Plus at $1,799, both read the same day. We charge $1,699 for either, so the Standard matches the maker and the Plus saves you $100 — and the list prices those discount from are $1,999 and $2,099.

Shop Pay on our listing shows two payments of $849.50 at checkout, subject to its eligibility check — the figure the listing's own payment terms carry today. Spread across the two-year warranty on frame, motor and battery, that is roughly $71 a month of covered ownership, before you count the years after it.

Buy something else if any one of these is true: you are over 6'1" or over 280 lb, you intend to pedal for exercise at speed, or you must carry the folded trike up stairs by yourself.

Each of those has somewhere to go. Over 280 lb, Eunorau publishes a 440 lb total payload for the NEW-TRIKE 2.0, $2,499. To pedal for exercise, take the geared folders in our folding e-bike picks; to carry it alone, the Eunorau META20 at 63.4 lb.

Above 6'1", our trikes guide shows you every height range we carry.

And buy something else if you need reverse. This is the one real omission, and it matters to a specific rider: a reverse gear is what gets you out of a bad stop. The Citytri has none. The Addmotor SpytanX Reverse is the trike we stock that does, at $2,599 — buy the SpytanX if that is you.

Before you buy: the checklist

Seven things to settle before you order, roughly in the order they bite: the setup week, the space you are folding into, the frame size, the payload, who lifts it, your local path rules and — today — your shipping address.

1. Give it a setup week. Assemble it, then ride it for a week and keep adjusting as you go — the saddle height, the handlebar angle, and the brakes if they need it. Every trike wants this, and it is the step easiest to skip; a week of small adjustments is the difference between a trike that fits you and one you tolerate.
2. Measure the space. Folded is 45.3 × 33.9 × 28.7 in on the Standard, 49 × 34.5 × 37.3 in on the Plus. Measure the bay, the trunk or the doorway before you order.
3. Pick the frame by your height, not by the color you like. Standard 5'1"–5'9", Plus 5'3"–6'1".
4. Add up rider plus cargo against 280 lb + 80 lb.
5. Decide who lifts it. If the answer is "me, alone, up steps", change the plan or change the trike.
6. Check your local path rules for trike width, and the minimum age if a young rider will use it — our law pages carry both.
7. Do not order to a New York City address yet. Addmotor's suspension covers all five boroughs, so we cannot ship this model there at present. Ask us and we will tell you when it lifts.

Why buy the Citytri E-310 from us

What our own service record on this model looks like. We have sold this trike for two years and have not had a warranty claim on one yet. One customer bought one for delivery work and has used it for a year with nothing failing on him.

The single complaint we have had was transit damage from the carrier: the packaging did its job and the freight handling did not, and we handled the claim — which is what the row above commits us to on your order.

Those are our sales and support records on this model rather than a laboratory durability result, and the numbers behind them are small.

Change of mind is covered too: unopened orders inside three days of delivery return at a flat 15% restocking fee — a number you know before you pay rather than a grade handed down after.

Frequently asked questions

Are electric trikes street legal?

Generally yes, but your state decides it. The federal statute that names three-wheeled machines, 15 U.S.C. § 2085, governs how they are regulated as consumer products rather than where they may be ridden; road use sits in state vehicle codes, and those commonly cover two- and three-wheeled machines alike.

What varies is where you may ride: bike-lane and path access for a trike is usually a width question set by the trail operator. Check your state's page.

Are electric trikes safe for seniors?

The stability argument is real: a trike does not need to be balanced, so it stands up at a stop, on a hill and while you get on and off. It removes the fall that happens at walking pace, when a foot does not reach the ground in time.

The risks that remain are cornering speed and traffic visibility, and both are managed by choosing a lower assist level and riding routes you know. Our guide for riders over 60 covers the fit numbers.

Do electric trikes tip over?

They can, in a fast corner, because a trike does not bank into a turn the way a bicycle does. A wide rear track and a low center of gravity reduce it, and slowing before the corner rather than during it removes almost all of it. This is the single riding habit to build in the first week.

What is the difference between the Citytri E-310 Standard and Plus?

Rider height and folded size, at the same $1,699. Standard fits 5'1"–5'9" with a 13.8-inch standover and folds to 45.3 × 33.9 × 28.7 in; Plus fits 5'3"–6'1" on larger wheels and folds to 49 × 34.5 × 37.3 in.

How much is the Addmotor Citytri E-310?

$1,699 here, whichever frame you take. Addmotor sells the Standard at the same $1,699 and the Plus at $1,799, against list prices of $1,999 and $2,099, all read September 19, 2026. Shipping is free in the lower 48.

What is the real range of the Citytri E-310?

Addmotor claims up to 90 miles at assist level 1, which works out to about 10.7 Wh per mile from the 960 Wh pack. A loaded trike on rolling ground draws more like 25 to 35 Wh per mile, which puts realistic planning in the 27 to 38 mile band. Treat 90 as the ceiling.

Does the Citytri E-310 have a throttle?

Yes, a half-twist throttle, alongside seven levels of cadence-sensed pedal assist. Both stop at the 20 mph cap, which is what keeps it inside the Class 2 definition in states that use one.

Where is the Addmotor Citytri E-310 manual?

Addmotor supplies it with the trike, and its product page is where the maker publishes support material. If you cannot find what you need, email the support desk with your frame and we will send you our copy.

Is the Citytri E-310 battery UL certified?

Yes — Addmotor states UL 2271 for the battery pack and UL 2849 for the whole electrical system. UL 2849 is the standard New York City's Local Law 39 turns on for the machine, with UL 2271 for the pack.

Can I buy an Addmotor trike near me?

We ship it free to your door anywhere in the lower 48, which for an 86 lb freight item is usually better than collecting it. One exception: Addmotor's suspension means we cannot ship this model to the five boroughs of New York City at present. Ask us and we will tell you when it lifts.

Where every figure came from

Limitations of this review

1. No instrumented measurements. The trike was ridden and filmed, but no range, speed, gradient or battery figure here was measured on that ride. Every performance number is Addmotor's published figure or arithmetic from it, and every road-tested figure belongs to the outlet named beside it. The ride tells you the hinge held, the trike reached its cap and it did not bog down; it does not tell you a mile figure.
2. The service record is ours rather than an audit. "No warranty claim in two years" and the delivery rider's year are our own sales and support records for this model. They are our own order and support figures, counted from our records, the sample is small, and not every unit behind them was sold into the US market.
3. The power cut-off is the maker's word; the switch is ours. Addmotor publishes the cut-off capability in its own product-page answer, read September 19, 2026. The physical on/off switch is what we found on our unit, and how it is presented may vary by build.
4. The torque figure is Addmotor's 90 N·m. A higher figure of 92 N·m circulates; the maker's published number is the one printed here.
5. The Plus height ceiling is contested. Our listing publishes 5'3"–6'1" for the Plus and this page uses it, including to turn away a 6'2" rider. Ebike Escape publishes 5'3"–6'3" for the same frame. If you are between 6'1" and 6'3", ask us before you rule it out.
6. Two Addmotor pages carry different motor ratings for the same SKU — 750 W on the US page and its two canonical siblings, 500 W on an export page quoting kilometers. This page follows the US page.
7. Peak output, torque and warranty term come from Addmotor's technical post rather than its specification table.
8. Stock is not asserted. Inventory tracking is off on this listing, so the storefront reports availability regardless of quantity. Ask us and we will confirm before you order.
9. Shop Pay figures are the listing's payment-terms data rather than a rendered sample plan. The plan you are offered depends on the eligibility check.
10. No recall was on file on September 19, 2026, and the CPSC's separate public-warnings view would not return results to us that day — for Addmotor or for a control term — so that list is unread rather than clear. Check both before you buy.

Expiry conditions — when this review goes stale. This page has no sunset date. It expires on events, and any one of these is the trigger to re-verify it:

• Addmotor changes the US product page's motor, battery or payload rows.
• The export page is retired or reconciled with the US page.
• A CPSC recall or warning naming Addmotor is published.
• Our price moves off $1,699, or Addmotor's own $1,699 Standard and $1,799 Plus move.
• Addmotor lifts or extends the New York City delivery suspension.
• The UL certification claim changes on the product page.

The bottom line

The Addmotor Citytri E-310 is the folding trike to buy if the fold is why you are buying a trike.

Pay $1,699 for either frame: two Shop Pay payments of $849.50, and $100 under Addmotor's own price if you take the Plus. You get three wheels that stand up by themselves, a 960 Wh pack certified to both UL 2271 and UL 2849, a real rear differential, a parking brake and a 360 lb payload.

Then it folds to roughly 45 by 34 by 29 inches and goes in the bay. The fold is what the money buys.

We have ridden it hard off pavement and sold it for two years, and the folding joint — the part everyone worries about — stayed tight under a 220 lb rider.

It is a single-speed cruiser with mechanical brakes weighing 86 lb, so it is wrong for a fitness rider, wrong for anyone over 6'1" or 280 lb, wrong for a third-floor walk-up, and wrong for a rider who needs a reverse gear. If none of those is you, this is the trike we would hand you.

Buy Red Standard — $1,699 · Buy Purple Plus — $1,699 — free shipping in the lower 48, Shop Pay from two payments of $849.50, and we file any warranty claim with Addmotor for you.
