Query: Worked well for about a week..

The bike came mostly assembled, after full assembly I rode it for about a week every day on some average forest trails (rocks, roots, etc.) nothing too hardcore and the bike held up well against abuse. But about all on the same day the bike started to fall apart, front wheel comes loose very easily, front brakes lock regularly. Rear wheel got wobbly for some reason, and worst of all the front fork suspension is stiff and won't absorb any more shock. The chain continues to fall off and the pedals broke almost day 1. This is a walmart quality bike, I didn't get what I thought I was getting. Put in an extra 100 bucks and get something that will last for more than a handful of rides.
