Issues and Assistance with Wuxing HT-268 Electric Bike Please

[Yellow Saddle]

Actually, weight could have some effect on maximum speed, couldn't it? Extra weight could affect the amount of friction in various bearings etc, which would therefore increase the resistive forces acting on the moving bike and thus reduce the maximum speed slightly?

Bearing friction in well-adjusted and lubricated bearings working within their load rating don't show enough increase in friction with load variances to make any difference. It is negligible. Wind speed is a far bigger factor as is incline. However, at zero incline, and for a given wind condition/aerodynamic condition, the maximum speed would be the same. Accelerating to maximum would be different for different weights of the vehicle but the end point, the same.
