Motors, Controllers and Batteries

  • Can I get higher top speed from the same motor by getting a higher voltage battery (48V vs. 52V on Hydra Black)?

    Speed is primarily a function of gear ratio. If you have sustained power being delivered continuously, the top speed will depend on the gear you are in. Top speed is not exactly dictated by voltage of the battery IF your battery’s power delivery is sufficient for the power rating of the motor. Yo...

  • What is the Archon X1 controller?

    Advanced motors need controllers that can smartly adapt to different conditions like current torque, speed, effort on the pedals, as well as battery capacity and drainage level. Archon X1 is our advanced creation to enhance the stock functioning of Bafang Ultra motor. It is a breakthrough in mid-...
  • What is the difference between hub-drive and mid-drive e-bikes?

    Typical e-bike motors are either hub based or mid-drive. Just like a car can be front wheel, rear wheel or mid-drive, so can electric bikes. Typical hub drive placements are in the rear wheels of electric bikes while mid-drive motors are typically placed in the middle of the e-bike also known as ...
