re: 60 MPH...achieveable? Who cares?!? Let blueprint an engine!
this is a pretty silly thread guys. bicycles are not made to do 60 mph. its that simple. anyone that has modified one of these motors on a bicycle to do over 35 mph know what happens. things loosen and things break. vibration on a one cylinder is way to much turning those kinds of rpms for a bicycle that is made to ride around at 6 mph average. i modified a cruiser and could get 37 out of it but things would fall apart and cruising at around 30 was max you wanted to do unless you wanted to get home and fix things. i have to say the virtual ice cream cone sounds pretty darn good though weekend-fun lol. seriously guys. if you want to do 60mph buy a motorcycle that has the shocks, the wheels,. the frame, the breaks ect ect that are designed for those kinds of speeds. the motorized bicycle is designed to have fun and enjoy things you are missing cruising around in a car or on a motorcycle at 60 mhp plus
