9 reasons not to buy

- Experts say the Thunder struggles on steep climbs.
- A buyer says many of the specs on the website are exaggerated or inconsistent.
- The Thunder lacks UL certification.

- Pedal assist power delivery is delayed by one revolution, according to testers.

Bottom line
The Qronge Thunder is a budget fat-tire e-bike with a 400lb payload capacity that offers a generally comfortable ride, especially on pavement and dirt roads. Reviewers enjoy the responsive throttle's gradual acceleration and high PAS top speed when unlocked. However, the cadence sensor feels crude, resulting in a choppy riding experience. While the bike is marketed as having strong power and brakes, testing shows it struggles on inclines, and its brakes are too weak. Reviewers are happy to overlook these drawbacks for the low price, but the lack of UL safety certification should be given serious consideration.Expert Reviews
