it has every thing you need

Note:

to get distance traveled you need to tape mesure your outside wheel
example: 10" tire has a 34" foot plant every rotation
13/65 = 4to1 gear ratio
Rear tire is 10" tall = 34" each turn
motor rpm:3000rpm (devided by) 13/65gears(4 to one) = 750 rear tire RPM
750 x 34" = 25500inch per minute(devide that by 12 will give you feet per minute)
25500"pm = 2125' pm
total = 24.147mph @3000rpm usable power
28mph@3500rpm (top end)
