Power Drive Alber EMotion M25 with ECS 24'' 652 You can combine the e-motion drive wheels with almost* any wheelchair using two discrete adapters. While moving, sensors built into the push rims measure your drive movement and provide you with the desired motor power. This allows you to move, steer and brake your wheelchair with very little effort. With a weight of only 7.8 kg per drive wheel, the e-motion is one of the lightest active add-on drives available. *Can be fitted to most manual custom/scripted wheelchairs.
