You will have a very hard time getting this thing started,it is my guess around 100cc or more.I did an approximate calculation of how much continuous force it would take at the pedals and came up with something like 150 lbs plus to overcome the compression of the engine, and that was assuming a 6" roller .It would require a down force of at least 80 lbs on the roller to keep it from slipping.Does not look practical to me.With that 6 roller size you would be doing 33mph at 3000rpm.
