I'm riding a dynatech maximum(Walmart I think). Anyways, I took a hit on the trails when I went riding with my friend the other day. Bent my flatbar. Now, I love riding this bike, its strong and light and handles every single damn thing I throw at it. But I'm worried to spend money on handlebars and upgrade the bike a little. I'm scared that it is a walmart bike and my money will be wasted. I need help.
