3COINS Foot-Powered Bike Carry Bag A convenient bag for carrying foot-powered bikes. The length of the handle is adjustable. ■Specifications■ Storage: Compatible with 12-inch bikes I think it can be used for Strider bikes. Convenient for preventing dirt and moving around! I think it's rare because you don't often see it in stores. I'm selling it because the size didn't seem right for me. I opened it once, but it's completely unused.
