With my last bike, as I said nobody wanted to touch it anyway, and I didn't have a clue.. Even after having it for over 3 months. and replacing a spoke about every 10 days, and watching YouTube videos on how to fix a spoke because I didn't have a clue. I got so pissed off thinking about it, I called Amazon and complained, so they said they'll request a return from the seller, but there was no guarantee they'd accept now. I said OK. A few hours later, even more pissed off I call again, just to let off steam, then they said they'll refer it to the team who can decided whether to refund me, if they think the bike was not fit for purpose. So I said OK. Then after walking 4 miles back from town, I called Amazon again and gave them a proper ear full, and demanded my money back, and 48 hours later I got a full refund, and still kept the bike, which I sold on... My current bike has Magnesium Alloy cast wheels, so no chance of them breaking .... Just a couple of things I want to modify, and I've pretty much found solutions on here reading a few past threads.. But there is a huge gap in the market for Pedelec repair shops, and someone is gonna end up a rich man out of this..
