Overview
The Windhorse W2B is a 16-inch folding ebike with a 630W peak (350W rated) motor and a UL2849-certified battery management system, aimed at shorter riders and campus or urban commuting. Windhorse lists a 19-35 mile pedal-assist range and a 20 MPH top speed.
Windhorse pitches the small 16-inch wheel size and adjustable fit for a 5'2 to 6'2 range, which reviewers under 5 feet tall confirm works well for them; at least one taller reviewer suggests the wheels feel small for adult use and recommends a 20-inch wheel model instead. A key-based ignition doubles as a basic anti-theft measure.
- 630W peak (350W rated) motor, 20 MPH top speed
- UL2849 certified BMS, removable battery
- 19-35 mile pedal-assist range
- Adjustable fit for 5'2 inch to 6'2 inch riders
Who it's for
Good fit for a shorter rider or student who wants a light, quick-folding commuter bike with certified battery safety. Taller riders may find the 16-inch wheels feel undersized compared to standard adult ebikes.
What buyers say
From Amazon customer reviews.
Shorter riders call the fit and speed a strong match, with one longtime cyclist calling it a favorite first ebike and appreciating the three riding modes for a workout option. A taller reviewer suggests the 16 inch wheels run small for adults, and one owner reports the bike stopped accelerating after about 3 months with the issue unresolved.
Strengths and trade-offs
Drawn from this product's published specifications.
- Fits shorter riders well, per multiple reviewers under 5 feet tall
- UL2849 certified battery management system
- Quick 4-step folding design at 52.8 lbs
Performance notes
The 350W rated motor with 630W peak output is built for city inclines rather than steep climbs, with three speed profiles and three riding modes covering throttle, pedal assist and manual pedaling. The dual suspension, front fork and saddle, is meant to smooth out uneven city pavement.
