Overview
A 14-inch folding electric bike with a 350W motor and 36V 7.8Ah battery, offering up to 20 mph and dual disc brakes for adults and teens.
DYU rates range at 15.5 miles on throttle alone and 25 miles with pedal assist, and the frame folds down for storage or car transport. Reviewers who bought it as a commuting or gift bike found it easy to assemble, though a few hit customer service snags over parts and warranty.
- 350W motor, 36V 7.8Ah battery
- Up to 20 mph, 15.5-25 mile range
- Folds to 50.2 x 8.66 x 24.02 inches, 47 lb
- UL2849 certified
Who it's for
Commuters or gift buyers wanting a compact, foldable e-bike for short city trips, including older riders who don't drive. Less suited to anyone expecting fast, hassle-free warranty support if something breaks.
What buyers say
From Amazon customer reviews.
Buyers commuting or gifting the bike to older relatives or teens liked how easy it was to assemble and fold for storage. Complaints centered on a slow warranty and parts-replacement process for at least one broken unit, a few missing screws on arrival, and confusion over how the 3 assist levels are supposed to work.
Strengths and trade-offs
Drawn from this product's published specifications.
- Folds compact for apartment or trunk storage
- Easy to assemble out of the box per multiple reviewers
- Dual disc brakes for reliable stopping power
- Good option for riders who don't drive, including seniors
- Warranty and replacement parts process reported as slow
- Some units missing screws on arrival
- Assist level switching not clearly explained in instructions
Performance notes
The 350W motor and dual disc brakes give it enough power and stopping ability for city streets, with an LCD display for battery status and 3 assist levels, though several riders found the difference between throttle-only and pedal-assist modes wasn't clearly explained in the manual. Folding takes the bike down to about 50 by 8.7 by 24 inches at 47 lb for storage or a car trunk.
