TRIWHEEL 14-Inch Mini Electric Bike

UL 2271 tests the lithium battery pack. UL 2849 tests the complete electrical system: battery, charger, controller and motor working together. The TRIWHEEL listing claims both and names TÜV Rheinland for each. That puts it with the RPINT Mini 14 and the Askmy Mini 14, which both name SGS, among the few bikes near this price whose UL claim comes with a lab attached. A claim that names a lab is one you can ask about. A bare "UL certified" is not.

What we could not do is confirm it. TRIWHEEL publishes no certificate number, we found no brand website, and a search on November 1, 2026 turned up no certificate that names this bike. Our reading: UL 2849 and UL 2271 are stated on the listing with the lab named, and not independently documented. If your building or city asks for proof before you charge indoors, ask the seller for the TÜV Rheinland certificate that names this model while you are still inside the return window. New York City requires UL 2849 or an equivalent for every e-bike sold, leased or rented there (NYC rules), and our battery fire safety guide explains what each test covers.

On speed, yes; on power, the listing leaves the answer open. The US three-class system caps Class 1 (pedal assist) and Class 2 (pedal assist plus a throttle) at 20 mph, and the federal definition of a low-speed electric bicycle in 15 U.S.C. 2085 is written around a 750 W motor. The TRIWHEEL states 20 mph and has a pure-electric mode, which means a throttle, so its speed fits Class 2.

The motor figure is the gap. TRIWHEEL quotes 1000 W peak. Peak is the short burst a controller allows on a hill start, while the statutes are written around rated (continuous) output, and the listing gives no rated figure. Plenty of 1000 W peak motors are rated well under 750 W (the Funhang City Cruiser 26 is 500 W rated and 1000 W peak), so this may be a Class 2 bike. A peak figure above 750 W cannot show it, though, so we leave the class blank on this page rather than guess.

Two checks are worth doing when it arrives. Look for the label many states require, stating the class, top assisted speed and motor wattage. And hold full throttle once on flat ground to confirm the display stops at 20 mph. New Jersey requires a license and registration for every e-bike, and Hawaii a one-time registration. Check your own state on the street-legal-by-state guide, and read the class explainer for why rated and peak are different numbers.

This listing's bullets give a 36 V 7.8 Ah pack, which is 280.8 Wh. That is the same size as the Gotrax Nano's and smaller than the 360 to 576 Wh most other 14-inch minis we cover state. TRIWHEEL claims 15 miles in pure electric mode and 25 miles with pedal assist.

• 281 Wh / 15 miles = 18.7 Wh per mile on the throttle, inside the 15 to 30 Wh per mile real e-bikes use. That claim holds.
• 281 Wh / 25 miles = 11.2 Wh per mile with pedal assist, below what an e-bike achieves in normal riding. That claim is too generous.

Plan on 12 to 15 miles on the throttle, and up to about 18 miles if you pedal steadily on a low assist level. That suits a round trip of 5 to 7 miles with some margin, on mostly flat ground. The title also mentions a 9 Ah battery and 30 miles: those figures belong to other listings in the same family, sold with a rear rack and a storage bag for more money, and 30 miles from 324 Wh needs 10.8 Wh per mile, so the same caution applies. If range matters more to you than weight, the Askmy Mini 14 carries 480 Wh for $183.99. Our range guide works through the arithmetic.

TRIWHEEL states a rider range of 4 ft 11 in to 5 ft 7 in (149 to 170 cm), a seat height of 28.7 to 35.4 inches, and a handlebar height of 33.5 to 40.2 inches from a folding, height-adjustable stem. That is more fit detail than most listings give, and the range is narrow. Inseam runs at roughly 45% of height, so a rider at the 4 ft 11 in minimum has an inseam of about 26.5 inches, two inches below the lowest saddle setting. Seated, that rider reaches the ground on their toes, which is normal with a saddle set for pedaling; to stand flat at a stop, slide forward off the seat. The seat post goes higher than a 5 ft 7 in rider needs, but the stated range stops there, and a rider near six feet should expect a cramped cockpit on 14-inch wheels.

At 43.9 lb it is lighter than most minis that publish a weight (the RPINT Mini 14 states 55 lb) and heavier than the 31 lb Gotrax Nano. The stem folds down for a car boot or a cupboard. The listing also calls it a "folding e-bike" under a "Compact Folding Design" heading but describes no frame hinge, so check the photos or ask the seller whether the frame folds before you count on a half-length bike. The 264 lb maximum load includes the rider and anything carried.

• Brakes: front and rear disc brakes. The listing does not say mechanical or hydraulic; at this price, expect mechanical.
• Tires: 14-inch pneumatic. No suspension is mentioned anywhere on the listing.
• Modes: pure electric, pedal assist and pedal only, with a claimed ability to climb 15% grades.
• Gears: none mentioned, so plan on a single speed.
• Lights: a front headlight and a rear reflector, with no powered tail light. Add a rear light before riding at dusk.
• Weather: IPX4, which covers splashes from any direction. It does not cover riding through deep water or hosing the bike down.
• Warranty and support: one year, with online customer support. We found no TRIWHEEL website, so treat it as a new brand and keep Amazon's return window in mind.
• Assembly: mostly pre-assembled, with tools and instructions in the box.

Buy it if you are between about 4 ft 11 in and 5 ft 7 in, your trips are a few miles each way on mostly flat ground, and you want a cheap e-bike whose UL claim names a lab. At $199.99 and 43.9 lb, with a stated rider range, it is a candidate for a shorter adult or an older teenager where state age rules allow (see e-bike age limits by state).

Skip it if you need more than about 15 miles a charge, if you are taller than 5 ft 7 in, or if you need the class settled before you buy. The RPINT Mini 14 at $199 quotes a 740 W peak, so its rated output is under the 750 W line, and pairs a 20 mph Class 2 cap with a 480 Wh battery and both UL standards via SGS, at 55 lb.
