Great kids pedals. Perfect replacement for kids bike pedals which easily break from frequent dropping. They are for Small feet and have no sharp edges that can scrape kids up when pedals catch them in the leg.
There are two pedal sizes on bikes, 1/2” and 9/16”. The 9/16” size is the more common option, found on most bikes. These 1/2” sized pedals are only used on basic bikes with a one-piece crank, such as some kid’s bikes. A one-piece crank is a solid, forged crank which is bent to run from one pedal through the frame to the other pedal, if you are unsure of the pedal size for your bike please check to see if the crank is welded into one solid piece or bolted.
