We have a decent selection of new 16" to 24" wheel kids bikes in stock starting at just $195, but if you're looking to save a bit of money on a used 20" wheel bike we have the one pictured above recently taken in on trade, that's selling for just $100.
It's a single speed with a coaster brake and a hand brake and it's in great shape, with the usual cosmetic scratches.
