Grin electric motor

 The Grin electric motor is built into the right rear wheel. The Grin electric motor is a powerful hub motor. The display is located centrally and clearly visible between the arm cranks. With the Grin electric motor you can turn your Varibike Trike into a 2-Wheel-Drive-Trike. You drive the front wheel with muscle power and the right rear wheel with the Grin electric motor. This two-wheel drive gives you enough grip. Thus you can also climb very steep climbs.
