    Hello my 70cc HT is coming in the mail, but Im trying to find out if I need a new bike. I'm not sure if the engine will fit inside my frame, but It looks like it will. Exactly how much room do I need?

    (I searched but couldn't find anything)

    Edit: I measured from the top inside of the crank and to the bottom of where the frame connects under the seatpost and it was 14 inches. I think i remember reading that was enough for the motor to fit in, but please correct me if I'm wrong.

    Thanks! I would like to put the motor on a cruiser though, I think it will be more comfortable for long rides.
