electrail offers the most flexible, economical and environment-friendly solution for motorized cargo transport. The system is based on the same principle as e-bikes: drive support depends on pushing the pedals. The support decreases with increasing speed. At 25 km/h, the motor switches off. However, the motor is not attached to the bicycle but to the trailer. A wireless transmitter sends the pedal movement to the trailer. Therefore, electrail does not require wiring on the bicycle. Neither is the motorized trailer dependant on a special bicycle. It can also be used with many different trailers.
The components
A pedal stick (1) records the pedal movement. It is a bit bigger than a USB stick and is attached to the pedal crank with an easy pinch.
The signal goes to the receiver that is located together with the engine control and the rechargeable battery in the e-box (2), a case in the trailer. A cable leads from the case to the motor (3). Some trailer models require an additional motor crank for the fixing the drive.
The components 1-3 are the three standard components and together are called electrail "Kit Standard". If a specific motor crank is added, the entire set is called "Kit X".
