The electric folding mountain bike I have I assume has tyres with no special puncture resistance, and it seems sensible to change the tyres to some with some puncture resistance, the tyres are rather big, which likely translates to heavy, and with high rolling resistance, and the worst track I ride on is likely the canal tow path, tyre size ISO 50 - 559 (26 x 1.95) Circumference in mm 2050 at moment, the motor setting are 06 = 026.0 which I suspect sets the speed readout correctly, so would like to fit smaller tyres which I hope will increase my road speed without using the motor.
Also looking at changing the front sprocket, as around 12 MPH at moment is about my limit as simply can't pedal much faster, can just about pedal at 16 MPH, above that I simply can't turn pedals fast enough.
The rear sprocket goes onto the motor, so not sure if I can change that, but front one seems a standard sprocket, my intention it to take it to bike shop to get tyres fitted, but I weigh 22 stone plus, and bike is 24 kg, so question is should I fit smaller tyres, or would doing that put too much strain on the wheel.
