My cruiser bike with a 2 stroke motor on it doesn't go that fast, maybe 25 mph on a flat surface. but i live where there are lots and lots of hills, and this bike can't get up lots of them. i want to put the motor on my racing bike because it's super light, but it has very thin racing bike tires. it also rains a lot in oregon and the ground is almost always wet is this dangerous? i want some detailed thoughts so i can make an informed decision about what I wanna do.
