electrail Kit 20
The electrail kit is available with wheel sizes of 16 and 20 inches. Everything you need to convert a trailer is included (see below, scope of delivery). Prerequisite: the wheel mount of the trailer is not a quick-release axle. The rear wheel must be mounted between two dropouts. A nut is tightened to the left and right of the wheel to secure it. The e-box fits in any trailer and the pedal radio is attached to the inside of the left pedal crank. The team is now ready for operation.
The following trailer models can be motorized with the Kit 20:
Roland Der Roland (Tiefdeichsel), Jumbo, Profi, Big Boy (jeweils mit Tiefdeichsel)
Do you want to retrofit another model? We are happy to check the feasibility. A photo of the wheel on the drawbar is sufficient, alternatively the model name of the trailer. We do not recommend our drive for models with a high drawbar and attachment to the saddle tube or luggage rack.
