clean and greese your freewheel. There may be something in there that is causing your cranks to keep spinning.

Bottom bracket

get a new one or get a qualified mechanic to service yours and inspect the entire crankset

this happenned to my friend and basically whats wrong isd that ur chain is way too tight...this stops the hub from racheting.

From the video it looks like you tried to make the chain tight for your SS but since you have vertyical drop outs you need to add a couple links and get a chain tensioner for the rear( like a derraler but just adds tension to the chain)

hope that helps

I dont mean vertical what I meant is that it isnt adjustable like a horizontal drop out on some higher end DJ/street frames. It has on place for the rear wheel....hope u get what I mean

it cant be ur bb cause there is no force on it when you take your feet off ur pedals therefore it will not move unless acted on by an outside force. Get a chain tensioner and add a few links to your chain and that should do it.

try shortening the chain first and see if the noise stops....the BB might be making the noise but it isnt causing the bike to pedal itself
