Hey guys,
I bought one of these kits recently for my 12 year old nephew whose been struggling with depression. I wanted to get him out of the house and teach him a thing or two about mechanics and two strokes in the process. I bought the Goplus 80cc motorized bicycle kit with a few other upgrades based on what I read would be good ideas to improve performance and safety. I bought an aftermarket carb with the offset intake manifold, a CNC sprocket adapter, an aftermarket chain tensioner, 2 shimano caliper brakes with a dual brake lever, a double leg kickstand, and an aftermarket NGK sparkplug.
The CNC sprocket adapter came with a 36 tooth sprocket which I definitely DO NOT want to use right off the bat. This is a build for my 12 year old nephew. He has a good head on his shoulders and at this point in his life I want him to start getting out into the world and enjoying what life has to offer. His father (my uncle-in-law) is all for the idea, but since I'm primary the one doing all the research on this project I'm responsible for making sure the build is safe.
I'm thinking of getting a higher tooth sprocket that will further decrease the top end speed, the 36 tooth sprocket increases top end speed past what the stock sprocket already allows for, but I'm not sure the stock sprocket is compatible with the CNC sprocket adapter. Can anyone recommend any mods I can do to limit the top speed to 15-20mph MAX? Any other suggestions for a young rider like this?
Kids need to get out and live more and experience the world! If the kid gets a few scrapes falling off his bike but has a smile on his face doing it, he'd be way better off then he is now! I just don't want him to get seriously hurt and I didn't realize how fast these bikes can go even without any serious mods right out of the box.
