Evolve GT - Top speed of 38mph (theoretical).

Hey all, I did a quick calculation of motor gear / wheel gear / and wheel size ratio and the possible speed to achieve on an Evolve GT skateboard. I saw on the forum 'tequilaman' verified that the motor gear of 20 teeth, with 97 mm wheel size achieves 33mph (that's slower than the calculated 34mph but probably due to increase wind resistance). The 107mm requires shaving 10mm off the width of the wheel to accommodate the rear wheel install.

Is it possible to achieve the theoretical 38mph? (or does the increase wind resistance at high speed make this not possible). Of course, throw the acceleration factor out completely if you want to achieve the top speed.

What is everyone's sweet spot on torque and speed and wheel size. It a balance game between distance, ride comfort, torque, and speed.

 

lol, I may have a similar spreadsheet for different gearing and wheel size for AT wheels I'm working on adding street wheels to it now. . .

Why'd you choose 20 tooth for a drive gear? Also, I still haven't figured out how gearing plays with range, so, maybe it doesn't really? It definitely affects top speed/acceleration(and climbing).
