Hi all,
I'm trying to get some prebuild questions answered. I'm building a gt2-a frame with a 66cc engine and would like to avoid the sbp shift kit. The problem is I do live in a hilly area and part of my commute is also flats.
My approach will be to get a rear nuvinci hub and use a disc sprocket adapter and run it straight from the engine to take advantage of the gearing.
If say my rear sprocket is 20t and the engine one is 10t what would be my range of speeds? I wanna try and keep the engine below 5000rpm for longevity.
Thanks in advance for any help!
