Bikes which were found abandoned in Brighton and were never claimed by their owners are to be sold on an internet auction site.
The city council has teamed up with the YMCA to sell the bikes and raise money for charity.
Highways enforcement officers collected 48 abandoned bikes this year.
They will be repaired and made roadworthy at the Sussex Central YMCA, before being sold on Ebay and at the YMCA centre next spring.
Some of the money from the sale of the bikes will go back into the scheme to cover running costs, the council said.
Councillor Geoffrey Theobald, environment spokesman, said: "This is an excellent scheme which not only provides reliable second-hand bikes at affordable prices but provides new job opportunities for young people and helps reduce the amount of waste destined for landfill."
Another aim of the scheme was to encourage residents to return to cycling without "spending a fortune" on a new bike, he added.
The project is running on a trial basis for six months.
