I built this bike in 2010 and ride it off and on since then. It operates flawlessly and only issue since 2010 has been new chain. You can ride it with engine running or engine off doesn't make much difference other then weight of motor system. I am getting up in age and don't ride much anymore due to health issues. My question is would anyone have any interest in a turn key moterized shifter bike for about 750. I hate to just hang it from the ceiling and not be used. I am located near Seattle Washington.
