The Motor

Rayvolt hubs are a very complex brushless 3 phase dc motor comprising of 48 different copper coils and magnets that are placed on the outermost perimeter of the motor for the best possible torque.

The built-in controller receives heat and position data from the coils and within one millisecond computes where to put the next load.

Such accuracy produces a Pure Sine Wave (PSW) current, offering unmatched ride comfort:

  • More Acceleration
  • More Response
  • More Torque
  • Less Noise
  • Less Vibration
  • Less Consumption

At the core of any electric vehicle, its performance and life expectancy are directly linked to the type of cell used. The capacity of the battery pack also depends on the amount of cells used.

Rayvolt uses 13 cells in a series to reach a nominal voltage of 48V. At peak voltage, a full charge of 54.6V gives incredible power. We use a minimum of 4 cells in parallel (52 cells in total) or 8 cells in parallel (104 Cells in total).

This gives an unmatched capacity of 550Wh and 1100Wh – most of the industry uses 300 to 360Wh.Battery quality is linked to the cells used and also the way it is packed. Using a state-of-the-art battery management system in our packs, each cell is connected to it before delivering the charge. This high-tech design balances the charge between each individual cell and can cut the connection in case of a short circuit. This ensures best possible performance while making the battery safer.

Intelligent Pedal Assist

With multiple choices power assistance with gyroscope hill detection Motor aid self adjusts.

Dual Sensor Crank Set

The Electronic Crank comes fitted with a Load Cell, which measures both the Torque applied to the pedal and the crank rotary speed. A Controller then computes these two values, and with a smart algorithm, provides perfectly smooth power based on muscle activity.
