36V/48V 25A Sondors Motor Controller - FREE SHIPPING

Upgrade your Sondors ebike!  20A, 25A, and 35A options for Sondors Bikes.  All controllers feature an extra headlight and horn output.

This controller features the bullet connectors as found on Sondors fat bikes with the bottle style batteries.

IMPORTANT!  Please make sure to select the correction version for your bike.

  • Sondors Ebikes from Indiegogo of 2015 are compatible with all parts.
  • Sondors Ebikes from later campaigns require BOTH the controller and LCD to function properly.  The controller will NOT work with a Sondors branded LCD, and the LCD we offer will NOT work with the stock controller.
  • Sondors Thin - Make sure to select the "25a triangle" option.  This is plug and play for the single speed bikes.
  • If you have a 7 speed bike, Sondors has changed the throttle connection.  We recommend one of our replacement throttles available here:  Note that the twist throttles would require changing the stock shifter on the bike.
  • Sondors Fold - Compatible with the 20A controller and LCD listed here.  The LCD cable requires an extension, some have also reported that the PAS requires an extension as well.
  • If you have a 7 speed bike, a throttle will also be required as Sondors has changed the connector.
  • Sondors with triangle battery - The battery connector is different from the original bottle batteries.  Make sure to select the appropriate version, as well as a throttle if you have a 7 speed bike.
  • 2019 Sondors FOLD bikes have changed wiring again!  Note that extensions for throttle, pedal assist, brakes, and LCD may be required, along with a new pedal assist sensor.  Unfortunately Sondors changes connectionss randomly with models, so it's difficult to make controllers 100% plug and play with all bikes.

25A - This 25A controller is a plug and play* upgrade to increase the acceleration and hill climbing ability of your Sondors ebike.  By changing to this controller, maximum power is increased to 900 watts with a stock battery, or 1200 watts with a 48v battery.  (Larger battery to handle the current draw is recommended)

48V:  This controller can also accept 48v batteries.  If you want to increase your speed, an aftermarket 48v battery combined with this controller can increase top speed, as well as acceleration and hill climbing ability.

*The controller is slightly longer than stock and will require a different mounting position.  Bolton Ebikes makes NO GUARANTEE to the longevity of the stock motor with this upgrade.

Motor compatibility:  This controller is compatible with both 350 and 500 watt Bafang motors.  It does NOT have the same plug as 750 watt motors.
