Output Examples

Recommended E-Bike Motor Setup

For a rider weighing 250-300 lbs who primarily rides on flat streets and desires a max speed of 20 mph (Class 1) with the option for throttle assistance (Class 2), I recommend the following motor specifications and model:

1. Motor Power and Torque Rating

  • Motor Power: 500W
  • Torque Rating: 85Nm

Rationale:

  • 500W provides sufficient power to support a heavier rider, ensuring that you won't feel underpowered, especially when reaching maximum speed.
  • 85Nm torque helps with acceleration and maintaining speed, particularly beneficial when using throttle mode.

2. Recommended Motor Model

Bafang BBSHD Mid-Drive Motor

  • Why Bafang BBSHD?
    • The Bafang BBSHD is a mid-drive motor known for its robust performance and high torque output, making it ideal for heavier riders.
    • Its 500W power rating and 85Nm torque ensure that you can achieve and maintain your desired speed without straining the motor.

3. Alternatives

a. Bosch Performance Line Mid-Drive Motor (250W)

  • Torque: 63Nm
  • Rationale: While slightly lower in power, Bosch motors are known for their reliability and smooth pedaling assistance on flat terrain. This motor is suitable if you prefer a brand with a strong service network.

b. Bafang Ultra Mid-Drive Motor (1000W)

  • Torque: 160Nm
  • Rationale: This is an over-spec choice that offers exceptional performance. It provides more power than necessary but ensures that you won't encounter any performance issues, especially if you decide to ride in varied conditions in the future.

Conclusion

Choosing the Bafang BBSHD (500W, 85Nm) will provide you with the necessary power and torque to comfortably enjoy your rides on flat streets without the risk of underpowering.
