About this category

Sports accessories are impulse buys and add-ons: they sell next to the bike, the shoes or the racket. This collection includes a compact bicycle bell driven by a torsion spring and a ventilated toe-box shield that sits inside basketball shoes, a skateboard truck built from a baseplate, one swivel pin and a rubber sleeve, and a BMX-style helmet whose chin bar clips off at magnetic, latching connectors.

Each patent was filed only in China, so they do not restrict these designs in the US. Each product page explains the mechanism, the realistic uses, and how to describe the product honestly - for example, a toe-box shield is a comfort and shape-keeping insert, not certified safety footwear.

What to look for in this category: light weight, simple fitting without tools, and clear sizing.

Also here: a handlebar mount that carries a phone cradle on top and a flashlight clamp underneath, and a competition-style kettlebell made from two pressed steel hemispheres that are welded together and filled to weight instead of being sand cast.
