“You’re used to changing your shoes and jacket to match the location or weather. Why shouldn’t you be able to do the same with your bike?” reTyre’s zippable tire-tread system gives your city bicycle the versatility to work off the road too. A simple zipping mechanism allows you to add a secondary, tougher tread on your tires, letting you go from riding on smooth asphalt to traversing through tough terrain. No matter the speed, the distance, or the condition, reTyre’s selection of treads make it the only set of wheels your bicycle needs… and in turn making your bicycle the only bicycle you’ll need too. reTyre’s special bicycle tire comes with a zipper lining and a selection of treads or skins that you can clad on your existing tire. The original tire works great on asphalt, and the wide variety of skins allow you to ride your bicycle on mud, gravel, rocks, or even snow. Working on straight roads, curved paths, and even on tough downhill trails, the tire treads give you exactly the grip you need, and the industrial-strength zipper system perseveres through rain, snow, or even rocky terrain… every single time. And when not in use, the treads easily fold up and go right into your backpack! Designer: reTyre Click here for YD’s .
