New guy with no mechanical experience and no DIY experience hopping into the forum to ask this:
All mentions of cheap DIY electric bikes have said to use a power drill as your motor, which makes sense.
But there's a very similar power tool that is much more powerful while still using roughly the same amount of energy: Impact Drivers.
Why not use one of those as your motive force? What damage could it do? Is there some mechanical reason that it simply would not work anywhere near as efficiently?
If you just read the above and wondered "Is this guy ********", don't worry, that's the sort reaction I usually get. Just try to get past it and assume I just don't know any better. Be elitists.
