1. How much does the assembly weigh?
2. How much is the drop center?

4. What is the diameter of you wheels?
5. What is the thickness of your sheet metal?

Thanks in advance!
Based upon our CAD, our drivetrain is at 66.5lbs with battery, electronics, transmissions, etc., 39.3lbs without electronics but with transmissions, and 13.6lbs with only the sheetmetal (belly pan, battery box, and the two siderails).

We have a theoretical free speed of 16.4fps high gear and 8.8 fps low gear.
