After a recommendation from a person I know who has better bikes than mine I recently purchased some Schwalbe Marathon Plus Smartguard Rigid tyres for my bike. It hurt a little bit spending around £25 per tire when I paid it but seeing as the previous tyres I had lasted about 150 miles and I had been using the bus for a couple of weeks before hand I realised I had to do it.

However, on the way to work this morning, I did some quick maths… slowly. Because I don’t do anything quickly when I’m cycling to work. With the bus journeys costing me at least £4.30 per day, having used the bike with the new tyres for two weeks I have already saved £43 in bus fares. Which means as of Tuesday next week I will be making a profit from cycling to work.

That’s how money works, right?
