Bike maintenance quiz answers

Below are the answers to our bike maintenance quiz.

1. How often should you clean and lubricate your chain?

Monthly, and also when it’s visibly dirty or you’ve been cycling in mud or heavy rain.

The chain is the thing that converts the muscle power of your legs, into mechanical power to make the bike move. Making sure it is properly cleaned and lubricated is worthwhile because it makes for less hard work by your lungs.

If you attend one of our adults’ or children’s bike maintenance classes, you will learn how to harness the magical powers of the Chain Bath, as seen in the video below:


2. Under normal road conditions, if you test the air pressure in your tyre by squeezing it with your thumb, then it should be as firm as:

The skin of an apple.

If your tyre pressure is too low, you will have to work harder to make your bike go. We find that most people forget to pump up their tyres properly. A foot pump is a good investment because it makes it easier to inflate your tyres. We have several at Northfield Ecocentre that you can use, including an all-weather foot pump outside the Ecocentre.  There is also an outside pump at Birmingham Friends of the Earth.
