Lewisham Cyclists’ bike maintenance and repair sessions
Whether you’re looking for a qualified mechanic to check over your bike or want to learn the skills needed to maintain your own bike, Lewisham Cyclists will likely have a session that is right for you. 
The different types of sessions they run:

• Mend and Ride Bike Workshop
• Dr Bike sessions
• Maintenance classes
• General advice

All of their maintenance sessions are run on a donation – “pay what you can afford” – basis

Greenwich’s Cycle Confident initiative offers training and courses, free bike loan for training, and free maintentance and repair at a Royal Greenwich Dr Bike session. Professional mechanics from Cycle Confident will check your bike to make sure it’s roadworthy, and make small adjustments and repairs if necessary, such as tuning your gears, adjusting your brakes or pumping your tyres. They will also be able to advise and refer you to a bike shop for anything more serious that cannot be fixed there and then.
