- CBv2 with 5063 motor = 0.65kg
- Full bike = 12.1kg !
Okay I upgraded the old CBv1 that had the small 5063 motor, to the CBv2 design.

The club I'm participating in is new at Purdue University, and you can check it out at electricvehicleclub.org, which was only put up couple of months ago. Many of the senior members are affliated with Purdue's evGP electric go-cart racing, so I suspect my future prototypes will come together well after having gaining access to machinery and guidance in the engineering building.
Actually, the brand new machinery rooms at purdue are very sophisticated, and they even have job openings. I plan on applying soon so I can learn to use their cnc and maybe even their water jet machines someday. Pretty cool oppurtunity, and, if I major in Mechanical Engineering, it will look really good on resume .
LUCKILY, my frame is pretty big at 59cm, not to mention they're 1" 1/8" tubes, also giving me extra room. I will try out the template today and get back to you, but I still haven't ordered a motor or esc yet. Waiting to see what club thinks. Btw, could/did you experiment with different tire widths?
