I have been slowly collecting parts for the rear 3 wheel conversion. The motorcycle donor I will be using comes from a Triumph Speedmaster. They use a 15x4 wheel which will allow me to mount a Continental ContiEcoContact EP. These cars are used on the Smart car fortwo =
Continental*ContiEcoContact EP
I really liked the idea of going with the Triumph Speedmaster to keep an all Triumph parts bin. Over the next few weeks I will be purchasing the rest of the parts needed from the Speedmaster to complete the transformation.
