Yes, Sidekick hubs are compatible with all Class-1 e-bikes; there are additional benefits for e-bike riders! 

E-bikes experience the same kickback effect as any full-suspension bike, the difference being that spikes in chain tension will be loaded into the motor, rather than feeding directly into the cranks and pedals. While this chain force typically wouldn’t be felt by the rider at the pedals, the negative effects on suspension performance are the same. 

Since e-bike motors operate with a torque sensor, the rider can use the highest deadband setting and still experience quick engagement of the rear hub. The motor will turn the chainring faster than the rider turns the cranks, more quickly taking up any slack in the chain. 

As an added benefit, chain vibration can cause a significant amount of noise with certain ebike motors, such as Shimano EP8 or Bosch CX motors with internal counter-acting clutches. On these bikes, Sidekick can significantly reduce or even eliminate this noise.
