DIYing is for anyone but not Everyone has the skillset Do it for others professionally for $

Anything done improperly can work for the moment but It's just like cheap parts cheap labor don't last long. In order to do things professionally means you need to be able to do things correctly and that involves more than it looking ok to your eyes especially if you don't know what your looking at. I always encourage DIY so that means just that Do it yourself. The only thing I won't recommend just trying is battery building, it's allot more to than you think and it's the one thing that you can't cheap out on not just because it affects the overall performance of your bike but it could be about life or death, DON'T LET JUST ANYONE be responsible for the safety of you and your family.
