Graduation project
Bike Spikes
Cesar van Rongen
Snow and ice are no fun at all in traffic. Cars have had winter tyres and skid chains for years; from now on, these are also available for bicycles! With Cesar van Rongen’s Bike Spikes wintry slips and slides are a thing of the past, without having to change tyres. A rubber casing with iron spikes to cover the bicycle tyre gives you grip on icy stretches, and on ordinary asphalt they will still be comfortable. The special winter bike tyre can easily be fixed to any city bike with the little key that comes with it. And when it thaws, the Bike Spikes can be taken off in an instant and folded into a compact little package.
