4 reasons not to buy

- An expert is disappointed by the lack of a rear rack.

Bottom line
The Retrospec Koa Rev 3 appears to be a decent option in the fat-tire e-bike segment. The hydraulic disc brakes are the notable upgrade over the previous version. The bike rides comfortably over light off-road terrain, and reviewers praise the range, responsive throttle, and stable handling. However, the motor struggles on steep hills, and, frustratingly, the brand doesn't provide a fit range. The limited testing and incomplete info make Retrospec's Koa Rev 3 difficult to assess conclusively, but competing models like Aventon's Aventure 3 and Velotric's Nomad 2 appear to offer a lot more at a similar price.Expert Reviews
