...advancing the bike.? My bike is fixed gear. I can ride it fine, but when i try to skid (pedaling backwards while going forwards) or when im going up a hill (Basically when a lot of pressure is used on the pedals), it would do this also. I went to the bike shop and the guy said he isn't the mechanic but it may have something to do with the bottom bracket. But I want your opinion. What is wrong and I would like to fix it myself so how would i do that.
I have a "fixie" btw.
