That’s one nice install. A few years back I put 66cc motor on an old 21 speed mountain bike. It was a hoot to scream around the neighborhood on. One day there was a radar board put up to encourage people to slow down in the area. Big mistake, I couldn’t go by it enough times to check my speed. Managed to hit 22mph for a top speed. Was a lot of fun.
I hope you get to enjoy your bike as much as I did mine.
