... It is putting out that much?... When it will never, ever put that much tq. out on practical application?
Its not. There are two systems at play. The friction force on the tire, and force that accelerates the wheel. Those two and only those two.. So... IF
You have a mid drive, with a first gear final drive that reduces tho motors tq. from say 100ft/lbs to 600ft/lbs...
You are NOT putting out 600 foot pounds. You will only put out to the maximum of the vehicles load needed to accelerate the vehicle, or break loose with the acceleration OF THE WHEEL... with no regard to the vehicles travel speed...
So if you have a powerful mid drive, or a center hub motor driven mid drive, YOU ARE NOT putting out 600 foot pounds even if that is what you calculated based on gearing and motor tq. ALl torque transferred through the friction will accelerate the vehicle to the point the tire can take. That is all.
Show me a tire on a Hayabusa that takes "600 foot pounds", and I'll show you HOW a 500lb Hayabusa rider/bike combo will NEVER put out that much load. With 200+ year old proven standardized engineering.
No bicycle tire takes 600 foot pounds. Period.
No 190/55/ZR17 takes that much Tq.
My ZX #1 made 90Ftlbs @ 8K and 600+ ftlbs wheel tq at the rear wheel. Theoretically. NEVER ever put that down, even in a sub 10-secong quarter mile past 140..
ZX #2 has 81 foot lbs at 8K rpm.
The Suzooki I had made 78 Ft/lbs.
The Bandit my dad had made 80 Ft lbs.
All calculate through the ration to over "600" ft/lbs on paper. Only on paper, though, not in practice.
Someone told me a Busa makes 600ftlbs+ in first on a launch. NOPE. WRONG. NOOOOOPe
No rice rocket tire takes 600 footlbs. Why do you think you are putting that through a bicycle tire. Lol.
You can calculate the tq your 1000ftlb Hemi Dodge Charger makes through the final drive and the gearing, with the 800Hp engine .. at 10,000 foot pounds.. Fact of the matter is a 5000lb car will never put out "10,000" footpounds.. Unless drag slicks. Then maybe,
Fun to brag about that though. Lolz. Quit braggin.
If it dont wheelie you aint making max tq. Even then its not the Tq you thin it is based on the motor rating.
Prove me wrong.
