Overview
A 20 inch fat tire electric bike with a 1500W peak motor, a 48V battery available in 15Ah or 25Ah, and a top speed regulated at 28 mph in the US, built with full suspension and dual mechanical disc brakes.
The battery is tested to the UL 2849 safety standard, and the bike offers three ride modes: pure electric, pedal assist and pedal only. A step-through frame option comes up repeatedly in reviews as a good fit for shorter riders, and the claimed 60 to 110 mile range depends on which battery is fitted.

- 48V battery available in 15Ah or 25Ah
- 20 by 4.0 inch tires with full suspension

Who it's for
Commuters and shorter or average-height riders, several of whom describe a comfortable fit around 5 feet 2 inches. Taller riders note sustained pedaling is less comfortable on this frame.
What buyers say
