A regenerative braking system on electric bikes works by converting the bike’s kinetic energy back into electrical energy during braking. Here’s how it works:

1. Braking: When you apply the brakes, the motor runs in reverse.
2. Energy Conversion: The reversed motor acts as a generator, converting kinetic energy into electrical energy.
3. Battery Recharge: This electrical energy is sent back to the battery, recharging it slightly.

Effectiveness:

• Energy Recovery: It helps recover a small amount of energy, extending the battery range.
• Efficiency: More effective in hilly areas where frequent braking is required.

Overall, while it’s a useful feature, the energy recovered is usually not very large but it does contribute to improved battery life and efficiency.
