"It has the motor and battery of a $2,000 bike, wrapped in the frame and suspension of a $600 one."
The '2600W peak motor' provides the burst of power needed to hit 40 MPH, but it cannot sustain that output. This is a system designed for short sprints, not for maintaining high speed up a long, continuous-grade hill.
This is for a tinkerer who wants a cheap entry point into the light electric motorcycle category and is willing to upgrade and repair components. The battery and motor are a good value; the rest of the bike is a starter kit you will inevitably need to improve.
Anyone expecting a reliable, turn-key off-road machine should avoid this. The low price ensures compromises on structural and suspension components, and its legal status as a motorcycle makes it unsuitable for riders who just want a Class 2 or 3 e-bike.
