Want Better Performance From Your E-Bike?
San Diego E-Bike offers high performance at a fair price. 52 Tooth Center Chainring Assembly
Don’t let the motor do all the work. Add longer distances because you can work with the motor. Faster Speeds to your E-Bike. Faster Speeds downhill (with no motor). Works good with 36 volts, but this is A MUST with 48 volts. Although this has no effect going up hills, your motor will last longer because of the decreased wattage (heat) in the motor, & increased wattage produced by you…yes this also means that you get more exercise at higher speeds because you can keep up with the motor.
