The gap between the seat and the cargo box has been filled in, seat lowered, padded with new foam which it really needs, wrapped with Naugahyde, and held together with hockey tape.
This is a modification of the existing seat, not an entirely new seat, although all new material was used.
More like a motorcycle, lower, further back, and the handlebars had to be adjusted to compensate. This ebike only has a 500 watt hub motor but it goes 28MPH. I pedal uphill and when accelerating. If I want to pedal I set it to 20MPH mode, and if I want to pedal harder I set it to 16MPH
