Built eBikes is proud to offer the best direct drop-in replacement motor for the Surron and Segway Platforms. We had begun testing and tuning with the KO Moto team as soon as they were available, and are proud to say the ability is here! You can now run higher power levels with a greatly reduced risk of motor over-temp settings being a factor.

Many Riders with BAC controllers and stock motors experience over-temp shutdowns and throttled power with even light trail riding in higher power levels. This greatly throttles the potential of the Surron Frame, but no more. We have personally not hit overtemp shutdown on any of our bikes and are very pleased with the amount of tunability and performance these new motors and controllers offer.

Be one of the first to receive the KO Moto Surron upgrade motor and controller. Designed from the ground up to give unmatched torque and power, without suffering from all of the issues that plague the stock Surron motor & controller offering.

Both the motor and controller are designed to be a plug and play option in the Surron and are easy to fit, using the same cabling and also the same default Surron display unit. Gone is the need to upgrade your display unit and run additional extra cabling across your bike.
