Bests & Worsts Reviews from Amazon

I really want to love this bike because it is very light, quiet, small and doesn’t require to be plugged in. However, there are two problems with it - one of the pedals keeps falling off no matter how many times we screw it back on. It seems the thread is bad so that’s why it doesn’t stay in place. Another issue is the bike is shedding black powder so the spot it usually sits on is completely black. It’s probably my own fault for putting it on the carpet but I’ve never had an issue like that with any other workout equipment. I am guessing this is from the magnets but I’m not sure.
