The cover of the latest issue of Bicycle magazine is set to go for a bid on the internet for up to £5,000 ($6,200) on eBay, according to a listing on the site.
The cover was made from a fabric made from the keratin fibres found in the inner lining of a bicycle frame, but is not currently being used for anything.
It is made of plastic, and it is likely that it will be sold on eBay for around £2,000.
The bicycle covers are made of a variety of materials, including leather and rubber.
The original cover is on sale for £15,000 at Bikes UK, a UK-based online auction site, with a reserve price of £3,000, or around £500 (about $6,400) less than the current price.
