Re: Got problems, please help!!
Nylock nuts are more resistant to loosening from engine vibration. They are good insurance on any motorized bicycle build.
Keep in mind, for items that get taken apart a lot, Nylocks will wear out if used too often. But for a permanent place like a motor mount bolt, it's a good idea.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
