We have snow again in York. I thought I had seen the last of that for this year. The tyres on my bikes are a bit too narrow and slippery for snow. But look at this! This would get me about.
It is a kit called the Ktrak that can be added to a normal bike. Typical, it has been around for a few years and I have only just discovered it!
Looks hard work though. Bet it works up a sweat.
