What size pedals do I need for a muddy fox Neptune boys mountain bike?
There are 2 sizes of pedals, they are based on the shaft size,thats the part that connects to the crank. The two size are 1/2 and 9/16ths. To determine your pedal size, take a ruler to the back side of the crank arm and measure the shaft size. If you have problems, take your bike to the local bike shop

im certain that model has a 3 piece crank set up. the inner crank bearing jam nut has loosened up or the bearings themselves have gone bad.first check to see if its tight, if it is then it will require a replacement set of bearing that are a pretty standard size to all bikes and can be purchased at nearly every bike shop.
