I love riding my bike. It's still breaking in, but I can easily push it up to about 23 MPH, but at that speed, I feel uncomfortable. Not because it's going too fast, but because of the vibration, and noise. I put in the cardboard, like we talked about a bit ago, and it made a difference, which helped. Loud noises scare me!! Hahaha. I don't like it, but I would love to feel comfortable at 22, 23 MPH. I rode my friend's 49.3cc 4 stroke moped today. Obviously it's not the same, but I was impressed with the speed and power. I was hitting 30 with no problem, and feeling extremely comfortable doing it. I'd love to be able to do that on my bike. Any ideas? I know the difference in motors is huge, and I know there's a reason why he paid $2500, and I paid $170. lol.... just curious if you guys have any ideas or tips. I've been looking around the forum and have seen some things. I've almost finished riding 1 tank of gas.
