– Take a firm grip on the cranks (arms that the pedals attach onto) and wiggle from side to side: if there is any movement, the bearings may be loose or your cranks may need tightening.

– Spin your pedals and check they are in good condition.

– Is the chain clean and lubricated, not heavily rusted or particularly long?

– Check that the cogs where the chain sits are not overly worn with flat teeth.

How to: Clean your bike… properly
