Man, yesterday I took the bike out and went down the California Incline which takes you from Santa Monica to PCH, and forgetting to stop at the first bridge, like an idiot I take the bike all the way down the incline. Mind you, I have a Diamondback and it's a pretty chill bike. Anyway, as I go down I hit a little slide of dirt on the ground and lose some control of the bike. I don't fall, thank god, so then I just walk and make my way back up to the bridge that takes you to the beach. So, as I take the bike path to Malibu, I'm just cruising along PCH when all of a sudden I get to the Getty Villa and there is a little area that has no sidewalk at all, and the land just protrudes out. You know, right next to that production studio place. Anyway, I lose control of the bike, but don't fall yet again. But now the back tire is acting sluggish. When I walked it, I saw that is was moving a little odd. Like wobbling from side to side.So, I turn back and then just coast it back to Santa Monica. I guess my question is, 1.) What would be the best place to take my bike: Helen's Cycles, Active, Bicycle Ambulance and 2.) What do you think is wrong with it? Is the axle messed up?
