How to choose your bike parts?

First, check the standards of your bike. Pedals are chosen based on type (flat or clipless), threading (common 9/16 inch), material (CNC aluminum) and bearings. The stem depends on diameter (31.8 mm most common) and length. Brakes (V-brake or disc) require compatible pads and levers. The saddle is judged by comfort, padding and rails. For the electric bike, the controller must match the motor and voltage. Always compare with the original part before ordering.
