If you think that your old aluminum bike wheels have no use at all and planed to discard it, then you must think a million times first before sending it to your local landfills. A clock master from Charlottesville will turn your old bike wheel into a trendy and useful clock. One of his great work is the recycled bike wheel clock. An old aluminum bike wheel is directly mounted into the wall. The hub with a hollow wall anchor makes the clock looks like hanging on the wall. The maker of this clock is proud to say that the clock movement is a high torque German quartz movement. With a measurement of 22 ¾ inches in diameter, the clock runs on a single AA battery.
