36V/48V Motor Controllers - FREE SHIPPING

  • 5499


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

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 Thin" option from the drop down.  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:  https://sierraebike.com/products/throttles
  • Sondors Fold - Compatible with the 20A controller and LCD listed here.  The LCD cable requires an extension:  https://sierraebike.com/collections/sondors-ebike-power-upgrades/products/sondors-lcd-extension-cable.  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.  

 

20A - The stock controller will typically run at a maximum of 450 watts.  By changing to this controller, maximum power is increased to 720 watts.  Top speed is not increased, but acceleration and hill climbing will improve.

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.

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.  Velomobile Shop makes NO GUARANTEE to the longevity of the stock motor with this upgrade.

35A - The 35A controller is significantly larger than stock and external mounting may be required depending your battery choice.  Note that this controller has a heavy duty motor plug which is NOT compatible with stock 350 watt motors!  Recommended for aftermarket 750 watt to 1500 watt motors.

 ONLY COMPATIBLE WITH AFTERMARKET LCDS OR 2015 SONDORS INDIEGOGO LCDS!
