The initial design planned to feature a double suspension swing arm at the rear, while the motor sits on the chassis driving the wheel through a chain drive. Due to problems with the chain tension, it was suggested to mount the motor directly onto the swing arm. At the same time, the whole structure is planned to move "inside the chassis". This would shorten the structure and allow a more favorable load path from the suspension into the space frame.
The new design is pictured below. The battery to be used is still under discussion. As major component in terms of both, investment and performance it plays a crucial role in the outcome of the project. We are currently looking for possible sponsorship agreements in order to purchase a suitable battery pack.
