I am loosing patience here, this is really bad since I weigh less than 120 lbs and I cannot understand what is wrong with the bike.
I am not riding hard at all, I ride mostly on the road and sidewalk, not even bike paths !
When I bought the bikes last month I was quite happy but since then I am having all kind of issues with both bikes. Overall I have spent more than 30 hours in total trying to solve this issue, I think I had enough.
