The attached flier gives details of the pop-up bike market that is coming to school this Friday. As set out on the flier, if you have a bike that your child has grown out of and you would like to sell it, please bring it along to school on Friday morning. The bike market people will then service the bike and contact you about a suggested sale price (and profit price for you. If you agree then they will put it up for sale after school on Friday.
So dust off those unwanted bikes as they could be given a new home (with you getting some cash in return).
