Ordered a bike chain in August for an e bike that I purchased from the company. Since I live in Michigan I didn't install the chain until March due to season. Now the chain doesn't fit and they won't allow me to return or exchange the chain the chain cost me $40 and after looking at the exact same chain on Amazon only cost $15. This is not the first time that I've been screwed by this company with bad business practices. My buddy built an ebike which is far more superior than the one I bought from them for far more money.
