Very simple: Because Schwalbe considers this as the only safe option to cycle in snow and ice.
Of course it would be nice to cycle without the permanent noise of the spikes. On a car, winter tyres with sipe technology and a compound which provides grip are a good idea. However, the situation on a bicycle is completely different.
You only ride on two tyres and when you start slipping on an icy road, you fall directly on your face.
Our product range comprises plenty of tyres with grip and coarse tread which offer good services on wet and cold roads, muddy forest tracks and even on firm snow. Whoever looks for such a tyre makes a good choice with tyres, such as Smart Sam or Marathon Mondial. But whoever wants to ride safely on an icy road, will have to choose tyres with spikes.
Can you ride with spikes also on normal roads? No problem at all. If, however, snow is rather seldom and the roads are mainly free, the running noises will soon become irritating.
And you don’t slip away? No. The spikes dig themselves very well into normal asphalt roads. Even fast curves are unproblematic.
Are spikes forbidden? On bicycle tyres spikes are no problem. In some countries, spikes are forbidden only for automotive vehicles, as they damage the roads. However, speed e-bikes are considered as automotive vehicles.
Is it necessary to run in tyres? To ensure the durable hold of the spikes, the tyres should be run in approx. 40 km on asphalt roads. Avoid forceful acceleration and braking during this period of time.
How long is the service life of spikes? All Schwalbe spikes have a core made of extremely wear resistant carbide (tungsten carbide). With these spikes you can ride a few thousand kilometers. The fact that the corners are rounded by grinding and the spikes are pressed deeper into the material is normal.
Individual spikes got lost. Can they be replaced? Yes, replacement spike kits incl. tools can be ordered from Schwalbe.
When do tyres reach their limits? In deep snow even tyres with spikes are no longer a help
In my region, snow is seldom. How can I make good use of tyres with spikes? The best option is to fit the tyres on a second bicycle. In the morning you decide which bicycle is suitable for the respective weather. On icy roads it is a great feeling to have full control on tyres with spikes, even when the cars drive very slowly.
