Hey i jsut bought some chinese chopper so its time to trick it out haha.. that frame seems solid so it should be fun to build on also, im kinda confused about the laws on these things, im 20 and have a drivers license. Im pretty sure you dont need a motorcycle license for a little 49cc but what about helmet, and how old do you have to be? for street riding.. or can you even ride them on the streets? haha thanks in advance
