BAFANG BBS02: Which Equipment to Choose?
Chainrings are available in different models with varying numbers of teeth. This choice significantly impacts the torque transmitted to your electric bike. If you opt for a small chainring, your bike will be more dynamic and responsive. This option is particularly recommended if you ride on mountainous or hilly terrains and want to quickly climb steep slopes.
It’s important to note that this configuration also protects your motor. It will operate within more efficient torque ranges even at low riding speeds without overexertion. Conversely, if you choose a chainring with a high number of teeth, your bike will be slightly harder to start but will achieve a much higher top speed. 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.
Be careful with larger chainrings. The motor can overheat during the start phase on steep inclines. If this exercise is repeated frequently, we advise you to stay vigilant. It is also advisable to check the compatibility of the chainrings with your bike’s chain line to avoid creating an unsightly chain line shape.
