I'm planning my first e-bike build, but I have some questions before I start. I think I understand the electronics behind everything, but I'm having trouble with the mechanical side of things. First, I'm deciding on whether I should do a 500W or a 1000W build on the front or rear wheel. The two host bikes I can choose to convert are a Specialized Sirrus aluminum frame or an All Gt Terra Outpost steel frame. Both bikes are relatively old, but they work (might need a tune-up). I was wondering what precautions I should take before building and while building to make sure the bike doesn't tear itself apart while riding.
Would a 1000W motor be able to be a front-wheel hub? It would be nice because it would be easier to convert and manage without having to deal with the gears and such of the rear wheel. How exactly would I go about putting the hub motor on to make sure it doesn't ruin anything?
Here are the parts I was thinking of buying. If anyone happens to know if these are good or not, I would greatly appreciate some feedback!
One last question: Is it worth it? I don't really need the bike too much for travel right now, mostly for fun, so is it worth stressing about it and spending 500 or so dollars to build my own e-bike?
Thank you very much for reading!
