now If you take the Design to one of the eager to please manufacturers at the next Taipei Trade show, with a big bank loan letter of credit
I imagine they will give you a batch quote to manufacture a few thousand of them , and once the CAD CAM program is sorted out.
when you sell through the 1st batch .. the next thousand will cost less,
Which one is better. and make the bike go faster
an electric Motor.
