Maintaining your bike well is essential to ensure you are safe on the road when you’re cycling. It’s surprisingly easy to learn how to do the essentials yourself. The London Cycling campaign offers lots of good advice. Alternatively, or if you have a more complex problem to resolve, you may feel more comfortable taking your bike to your local bike shop.
Transport for Greater Manchester also often run free bike checking sessions at cycling events around Greater Manchester. Check the upcoming events for details.
