This is a unique wall clock made from recycled bicycle sprockets & a very eye-catching bike brakes rotor. This bicycle clock is made with several kinds of sprockets, in different sizes. The clock measures around 6.3'' ( around 16cm ) in diameter. Made with a brand new, non-ticking clock mechanism. All my bicycle clocks are made from real, used bike parts. They are thoroughly cleaned but might show some signs of previous usage like small nicks, scratches or small spots. in my opinion that adds to the item's charm. It will make a great gift for any bicycle lover or someone who already has everything. It also looks great & will make a great conversation starter in your home or work place. & of course, it tells time! :) Check out my other stuff: clocklight.etsy.com Thank you for looking, & if you have additional questions don't hesitate to ask, I'm here to help.
