Ridstar Q50 2000W 25Ah Fat Tire E-Bike
The biggest battery Ridstar sells, at the lowest cost per watt-hour.



Ridstar Q50 2000W 25Ah Fat Tire E-Bike
The Q50 25Ah pairs Ridstar's 2000W brushless motor with a 48V 25Ah battery, about 1,200 watt-hours. At $759 that works out to roughly $0.63 per Wh, the lowest of any bike in our Ridstar guide, which makes it the default pick if range matters most. Ridstar claims up to 65 miles, a top speed of 28+ mph and a 330 lb load capacity. Treat the range as a best case, since throttle-only riding, hills and rider weight cut it sharply. The $60 step up from the 20Ah version buys 25% more battery, which is the better deal. Like every current Ridstar, its power and speed exceed the federal low-speed e-bike definition (750 W, 20 mph), so check local rules. This model is not named in the 2026 CPSC warnings, which cover the Q20, Q20 Pro and Q20 Lite. That does not mean CPSC has reviewed it. Specs and price are from ridstar.net on Oct 16, 2026.
