I have I bike I purchased new from my local bike store back in 1996. The bike needs some work so I was toying around with the purchase of an e-bike. Since finding Johnny's content on YouTube, I'd so much rather upgrade my existing bike. I was wanting to do something like the Bafang 750 mid drive. Prior to any unfitting, my current bike needs some repairs (Brakes, gears are worn/shift levers). The frame is solid and has never been damaged/repaired.
Option 2 would be to find a newer used bike and perform the upgrade.
