60 mph :117_running_dog:
Helmet & seat belts mandatory and a
Hurst shifter to change speeds.
Should be interesting. What size belt do you to jump up to?
Do you really grind at that speed? that's over 5000 feet per minute, or 57MPH. If it flies off, you'll get a speeding ticket :les:.
Put another way, that speed would create about 220-g's of force - each pound of rubber on that rim would be pulling away from the center with about 220lbs of force.
