How easy is it to do bicycle conversion?

Question

Help I am looking at buying a gas powered conversion kit to put on my mountain bike. Can anybody tell me how easy/hard is it. What tools I need any advice in general is appreciated.

Answer 1

I just saw a kid with one the other day, it looked easy to me, like they installed the little motor and everything themselves.  You can probably find out at the shop that sells the kit, but I imagine you just need hand tools.
