Last week the gears wouldn't shift. I fixed that by adjusting the barrel. I'm a 400 lb 6"5 rider on a 25" frame.
Now I've got two more issues...
1. A "click" noise down by the pedals. It only makes the noise when I'm on it and spinning. The noise occurs at certain locations on the rotation, and will not happen if I'm coasting or spinning the pedals by hand if I'm off the bike. It has gotten progressively worse over the last week, and there are no cables or anything I can tell getting in the way.
2. An issue I first realized today, it seems like my front wheel is wobbling. About once a second, I feel like the bike "pulses" and sways to the side a tiny bit. It's not noticeable when I'm spinning, but is obvious when I'm coasting. My untrained eye doesn't see any obvious damage to the wheel tire or spokes. I'm not positive it's the front tire since I can't see the rear, but feel it more up there.
Any ideas whats going on? Is it likely they are related?
