BAFANG BBS01: Which Equipment to Choose?
There are different chainring models for electric bikes, with a varying number of teeth. This number of teeth affects the torque you transmit to your bike. The fewer the teeth, the greater the torque transmitted, making the bike more responsive and dynamic. This configuration is particularly useful in mountainous terrains where the slopes are steep and require quick ascents.
It’s important to note that this configuration also protects the motor. It will operate within an optimal range without overexerting, even at low speeds. Conversely, a higher number of teeth will make the bike slightly slower at low speeds, but its top speed will be higher. However, it’s essential to be cautious not to overheat the system during starts or on steep inclines, as a large amount of energy generates heat under these conditions.
It’s crucial to check the compatibility of the chainrings with your bike to avoid setting an unsightly chain line. In summary, the choice of the number of teeth will depend on your usage and the type of terrain you ride on.
