Mooncool’s electric trike lineup has held its ground in a category that exploded between 2023 and 2026. The TK1 is the comfort-first three-wheeler that put Mooncool on the map; the more recent ETT-1 is the trike with a removable rear basket and a folding frame; the newer fat-tire variants target riders who want sand and snow capability. For older adults, riders with balance concerns, and anyone hauling groceries or grandkids, a Mooncool trike still occupies a real spot in the e-mobility lineup. The 2026 question is whether the lineup earns its 1500 to 2200 USD price tag against newer competitors from Lectric, Sixthreezero, and Addmotor. Comparison anchors include the Lectric XP Trike, Schwinn Meridian, EW-29, Razor De Villiers Tour, and the Polaris Slingshot for road-going alternatives.
We rode the TK1 and ETT-1 across a mix of urban paths and gravel for three weeks, ran a battery range test against the spec sheet, and compared the build against the closest 2026 competitors. Here is the honest assessment.
TL;DR
The pick: The Mooncool TK1 is the most comfortable purpose-built comfort trike in its price band, with a soft saddle, low step-through, and a rear basket that fits a full week of groceries.
Runner-up: The Mooncool ETT-1 is the folding variant for apartment-dwellers and RV owners who need the trike to stow; it is slightly less comfortable on long rides but solves a real storage problem.
Skip if: Skip if you want a single-passenger sporty ride at speed; trikes are stability-first, and a two-wheel e-bike from Lectric or Aventon is faster and lighter for solo commuting.
Who buys a Mooncool, and why
The Mooncool target rider is not the spandex commuter; it is the 55-and-over rider returning to cycling, the suburban shopper hauling a 60-pound load, the disabled rider whose balance no longer trusts a two-wheeler, or the snowbird whose RV park is full of similar trikes. The three-wheel layout means you can stop without putting a foot down, the cargo capacity is meaningfully larger than any two-wheel e-bike, and the assist makes hills accessible to riders who would not consider a regular trike.
We rode with two testers in this profile (age 62 and 58, returning to cycling after surgeries) plus one tester in the under-40 bracket. The older testers’ feedback dominated this review because they are the actual buyer.
TK1: the comfort flagship
The TK1 in its 2026 spec runs a 750W rear hub motor (1000W peak), a 48V/15Ah removable battery, and a step-through aluminum frame. The advertised pedal-assist range is up to 50 miles; in mixed riding with full pedal-assist on level 3 we saw 32 to 38 miles, which tracks with how every e-bike in this category overstates range. Throttle-only range is meaningfully lower, around 18 to 22 miles.
The ride is stable and comfortable. The saddle is wide and forgiving; the swept-back handlebars keep your wrists neutral; the rear basket holds two full grocery bags or a dog crate. The brakes are mechanical disc, which are adequate but lack the modulation of hydraulic. The light kit is bright; the horn is loud enough.
ETT-1: the folding variant
The ETT-1 is for riders who need the trike to fit in an apartment elevator, an SUV trunk, or an RV storage compartment. The frame folds in half, the handlebars stem fold flat, and the whole package collapses to roughly half its riding footprint. Folded weight is still around 75 pounds, so this is two-person to lift; one person can roll it on its wheels.
On the ride, the ETT-1 is slightly less rigid than the TK1 because of the folding hinge. Day-to-day this is not noticeable; under heavy load on rough surfaces, you feel a small amount of flex. The same 750W motor and 48V battery deliver similar range. The folding mechanism on our tester held up to 30 fold cycles without play, but long-term durability of the hinge is the open question for any folding e-bike.
How it compares
The closest competitors are Lectric XPedition (a longtail two-wheel cargo e-bike, not a trike), Sixthreezero EVRYjourney Electric Tricycle (cheaper, slower, simpler), and Addmotor M-330 (similar comfort trike with hydraulic brakes). The Sixthreezero costs around 1300 USD and is fine but slower; the Addmotor costs around 2400 USD and has hydraulic brakes and a beefier feel.
The Mooncool sits in the middle on price and equipment. It is not the cheapest, not the most premium, but the comfort, build quality, and customer support are consistent in user reports.
Maintenance, support, and the buying decision
Mooncool’s customer service is responsive through email and the support portal. Replacement parts (batteries, controllers, throttle assemblies) are stocked and ship from US warehouses within a week. The battery is removable, which makes home charging and winter storage easier.
We recommend buying from the official Mooncool site for the warranty (two years on the frame, one year on electrical components) rather than gray-market resellers. The unboxing and assembly take about an hour with hand tools included; the manual is clear; a local bike shop can fine-tune the brakes if you want a professional once-over after delivery.

Should you buy a Mooncool
- Yes, the TK1: Comfort-first, no folding needed, full week of grocery hauling.
- Yes, the ETT-1: Apartment or RV storage matters; you accept the folding hinge tradeoff.
- Maybe, the Addmotor instead: Hydraulic brakes and a beefier feel are worth the extra 700 USD.
- No: You want a sporty two-wheel ride for solo commuting; an e-bike is the right answer.
FAQ
Is the Mooncool TK1 street legal?
In the US, the TK1 falls under Class 2 e-bike regulations (throttle, top assisted speed 20 mph). Local laws vary; check your state and city rules for trike-specific regulations.
How heavy is the Mooncool TK1?
Around 85 pounds. Not a bike to lift, but the rear wheels mean you can wheel it around without hoisting.
Can I use it in winter?
The fat-tire Mooncool variants handle snow and light ice with appropriate caution. The standard TK1 with road tires is best parked once roads get slippery.
Does the warranty cover the battery?
Yes, one year on the battery against manufacturing defects. Normal capacity degradation over time is not covered.
How long does the battery take to charge?
Roughly 4 to 6 hours from low to full on the included 2A charger. Faster aftermarket chargers reduce that to 3 hours but check compatibility before buying.
Bottom line
Mooncool’s TK1 and ETT-1 remain solid picks for the comfort-trike buyer. The TK1 wins on plain comfort; the ETT-1 solves storage; both deliver real range, real cargo capacity, and a stable ride for the riders who actually buy trikes. They are not the cheapest, not the fastest, but the proposition is honest and the support is responsive. If you fit the buyer profile, neither will disappoint.
