Before you consider passing on or disposing of a bike which is in need of repair and replacing it with a new one, why not try and mend the one you have? Help is available in the form of free bike repair and maintenance resources such as https://www.bikeride.com/ which offers online repair guides and tutorials for the amateur bike enthusiast.
Advertise locally in free papers, bike shops, supermarket notice boards, jumble sales or car boots sales.
If your bike is in good cosmetic condition you can donate it to the Smugglers Way Household Waste and Recycling Centre, SW18 where it will be passed on to a local business to clean them up and replace any parts that need replacing. Your bike can then be reused by another.
If your bike is beyond repair, take it to your local reuse and recycling centre and put it in the scrap metal bin and then it can be recycled.
