Really sorry to be a new poster asking for help but in spite of the rudeness of it I hope someone can still answer my problem.
I've recently moved abroad and so the only bike I've got here is a crappy old hand me down from a friend.
I've managed to fix most of the problems with it but quite a critical one remains- the pedals are out of line.
At first I thought the sprocket was warped but on closer examination the entire crank (I think this is the right English word) is loose. Sometimes its perfectly fine and in line and works but as you pedal it makes its way out of line and locks up.
How (is there any way?) would I go about setting the pedals in place?
The bike is just a standard Dutch cycle (which is odd to find when I leave Holland...), no gears or anything and pedal backwards to break.
