Seven of the eight adult trikes fold

We compare eight adult electric trikes; the Mooncool CD1 is a youth model and is left out of everything below. By their makers’ spec pages (checked October 2026), seven of the eight fold. The one with the fold in its name is the Mooncool TK2, at $1,500 with a 720 Wh battery, a 500 W motor and a 15.5 mph top speed, but Mooncool marks the TK Pro, TK2 PRO and FT1 as foldable too. Lectric lists the XP Trike2 with folding hinges at the stem and frame, and Emojo lists a foldable frame on the Dexter and Dexter Jr. Only the Emojo Bull has no fold on its spec page. With nearly every trike here folding, the useful questions are what each one weighs and how big it is once folded.

Here is how the eight divide, with each maker’s folded size (length x width x height):

• Folding: Mooncool TK2 and TK2 PRO (39.4 x 28.7 x 26.8 in each), Mooncool TK Pro (39.9 x 29.9 x 30.7 in), Mooncool FT1 (41.3 x 33.5 x 50.4 in), Lectric XP Trike2 (36.5 x 38 x 26 in, or 30 in wide with the front wheel off) and Emojo Dexter and Dexter Jr. (42 x 31 x 27 in each).
• No fold on the spec page: Emojo Bull.

Specs for every adult trike side by side are in the 3-wheel e-bike guide, and picks by rider need are in best electric tricycles for adults. This page stays on the fold itself.

Folded is not light: the weight problem

A hinge changes a trike’s shape, not its mass. Mooncool lists the TK2 at 41 kg, or 90.4 lb. Lectric lists the XP Trike2 at 79 lb without its battery and its standard battery at 7 lb, so about 86 lb with it, the lightest of the folding trikes. Among the folding Mooncool and Emojo models the TK2 is the lightest, though not by much: 2.6 lb under the Emojo Dexter and Dexter Jr. (93 lb each), 6.6 lb under the TK Pro (97.02 lb), 8.8 lb under the TK2 PRO (99.2 lb) and 15.4 lb under the FT1, which Mooncool lists at 48 kg, about 105.8 lb. Emojo’s 93 lb includes the battery; Mooncool gives a net weight and does not say whether the battery is in it.

The more telling comparison is with folding two-wheelers. The folding e-bikes we compare that have a published weight run from 60.6 lb (Himiway B3) to 79.4 lb (Heybike Horizon). The heaviest of them is 11 lb lighter than the TK2 and the lightest is 29.8 lb lighter; against the XP Trike2 with its battery (about 86 lb), the gap is about 7 to 25 lb. A folding trike sits at the heavy end of “folding”; it is not a trike-sized folding bike. If carrying it is the problem you are trying to solve, the folding e-bike guide is the better starting point.

Lifting is where the number bites. The NIOSH lifting equation starts from a 51 lb limit for a compact load held close to the body under ideal conditions. The TK2 is about 1.8 times that (90.4 / 51 = 1.77), and the XP Trike2 is about 1.5 times that even with its battery out (79 / 51 = 1.55). An awkward frame is harder to keep close to the body than a box, which pushes the practical limit lower still. For most people, getting it into a vehicle is a two-person or ramp job.

Choosing between folding trikes

All seven trikes in the table below fold, so the choice between them is not about the hinge. The TK2 is neither the lightest nor the cheapest of them: the Lectric XP Trike2 weighs at least 4.4 lb less with its battery fitted, and the Mooncool FT1 and Emojo Dexter Jr. list for less. Against the Lectric it offers more battery for the money; against the TK Pro and TK2 PRO it trails on battery and motor.

Against the TK Pro. The TK2 lists $200 lower but gives up 240 Wh of battery and 250 W of motor. Per watt-hour it costs more, $2.08 against $1.77, about 18% more (2.083 / 1.771 = 1.18). At 30 Wh per mile that is 24 planning miles against 32, a quarter less range.

Against the TK2 PRO. The price per watt-hour is identical at $2.08, so the extra $500 for the PRO buys exactly the same 240 Wh and 250 W, and adds 8.8 lb of weight.

Against the Lectric XP Trike2. This is the closest match on price: the Lectric XP Trike2 lists at $1,499 (maker list price, October 2026), a dollar under the TK2. For the same money the TK2 has 96 Wh more battery, 1.5 mph more top speed and a 35 lb higher load rating, which works out at $2.08 per Wh against $2.40. The Lectric is at least 4.4 lb lighter, and Lectric lists UL 2849 certification for the trike and a UL 2271 battery (Lectric’s product page, checked October 2026).

Against the Dexter, Dexter Jr. and FT1. The TK2 lists $99 under the Dexter with 48 Wh more battery and a 150 lb higher load rating, but tops out at 15.5 mph against 20 mph for both Emojos. The two Emojos also carry the lowest load rating here, 300 lb. The Dexter Jr. lists $200 under the Dexter with the same battery, motor and folded size, on 16 in wheels with mechanical disc brakes and a single speed instead of 20 in wheels, hydraulic brakes and 7 speeds. The FT1 is the cheapest at $1,350 (maker list price, October 2026) and $1.94 per Wh, but has the highest published weight at about 105.8 lb, and it folds to 50.4 in tall against 26.8 in for the TK2, so check your cargo opening first.

The cost no spec sheet prices is the hinge itself: one more joint that has to stay tight and one more latch to engage every time you unfold. None of these makers’ spec pages gives durability or frame-stiffness figures, so there is nothing to compare. Mooncool’s warranty terms are worth reading with that in mind: the frame is covered for life, but the stem and other parts for one year.

Storage: measure before you pay for the fold

Each maker’s folded size is in the list near the top of this page: the Mooncool TK2, for example, folds to 39.4 x 28.7 x 26.8 in (length, width and height) and the Lectric XP Trike2 to 36.5 x 38 x 26 in. Hold the folded size against four measurements of your own:

1. The narrowest opening on the route. Measure the clear gap between door stops or gate posts, not the door leaf. A standard US exterior door is commonly 36 inches wide and interior doors often 30 to 32, and the clear gap is usually a little less once hinges and the door itself are counted.
2. The parking spot. Folded length and width, plus room to unfold without moving anything else.
3. Every step on the route. At 90.4 lb a single curb or stair is a lift. A flight of stairs is the case where the fold helps least.
4. The charging socket. The battery has to charge somewhere. Lectric and Mooncool describe the XP Trike2, TK Pro and TK2 PRO batteries as removable; for the other models, ask. A pack that comes out can be carried indoors; one that does not needs a socket beside the trike.

The fold can change width and length. It cannot change items 3 and 4. If your obstacle is a doorway or a tight corner, the fold may fix it; if it is a staircase, it will not. And if one narrow gate is the whole problem, widening it may cost less than choosing a model for its hinge.

Transport: three routes and where 90 lb bites

We do not compare racks, carriers or ramps, so these are checks to make rather than recommendations.

• Inside a car or van. Compare the folded size with the cargo opening, not the cargo floor, and with the height under the open tailgate. Then decide who lifts 90.4 lb and from what height. A low sill or a ramp decides this more than the hinge does.
• On a hitch carrier. Check the carrier’s rated load against the trike’s weight, and the receiver’s tongue-weight rating against the trike plus the carrier’s own weight. Carriers built for two wheels may not suit a trike’s wide rear axle, so confirm the tray width with the carrier maker.
• Not at all. If the trike lives where you ride it, you would be paying for transport you never do. Judge it on battery and motor instead.

Certification and charging

Every maker here states a safety certification (last row of the table). UL 2849 examines an e-bike’s electrical drive train, battery and charger together; UL 2271 covers the battery pack. Labs other than UL can certify to these standards, and Mooncool names SGS as its lab, though the FT1’s page says SGS tested it to UL 2849 rather than certified it. Lectric and Emojo do not name a lab on these pages; ask for the certificate if it matters to you.

Wherever the pack charges, follow CPSC’s micromobility safety advice: be present while it charges, never charge it while you are asleep or away from home, and unplug it when done. Use only the charger supplied with the trike or one its maker recommends, and only a spare or replacement pack the maker has approved for that trike. The makers quote 5 to 7 hours (Lectric’s standard charger), 7 to 8 hours (Emojo) and 7 to 9 hours (Mooncool FT1) for a full charge, so plan it for a stretch of the day when you are home.

Five questions to put to the maker

1. Is the published folded size measured with the front wheel, seat and baskets fitted? Lectric gives two sizes, with and without the front wheel.
2. What does it weigh with and without the battery, if the pack comes out?
3. Does the fold need tools or a second person, and how long does it take?
4. How is the frame joint warranted, and how do you confirm the lock is engaged?
5. Does a rear basket or cargo box stay fitted when folded?

Folding trike questions

Do the TK Pro and TK2 PRO fold too?

Yes. Mooncool’s spec pages mark the TK Pro, the TK2 PRO and the FT1 as foldable, not only the TK2. The TK2 PRO folds to the same 39.4 x 28.7 x 26.8 in as the TK2, and the TK Pro to 39.9 x 29.9 x 30.7 in. Only the TK2 carries the fold in its product name, so the naming tells you nothing either way.

Is a folding trike as stable as a rigid one?

The standing-still stability that comes from three wheels is there whether or not the frame folds. What no spec sheet here tells you is how a hinged frame holds up over time or in hard cornering: none of these makers publishes stiffness, durability or tip-over data.

Should I buy a folding trike or a folding e-bike?

Choose by the problem. If balance is the reason you are looking at three wheels, a two-wheeler does not solve it, and seven of the eight adult trikes here fold. If weight is the problem, the folding e-bikes with a published weight are 11 to 30 lb lighter than the TK2 and about 7 to 25 lb lighter than the XP Trike2 with its battery fitted. If you are still deciding between a trike and a bike at all, the trike versus bike guide works through that.

Everything above comes from the makers’ published specifications, checked October 2026 on Mooncool’s TK2, TK2 PRO, TK Pro and FT1 pages, Lectric’s XP Trike2 page and Emojo’s Dexter, Dexter Jr. and Bull pages. We have not handled or folded any of these trikes, which is why this page tells you what to measure rather than how a fold feels.
