Schwinn 15-Function Wireless Bike Computer
The Schwinn 13-Function Wireless Computer provides speed, time, distance, and training functions without difficult to install wires--or--wheel interference. The computer's friction-free sensor measures the turns of the wheel without contact the rim or tire. The large LCD screen, meanwhile, provides the rider with a clear view of all speed and distance measurements. The computer sensor, transmitter, and receptor mount directly onto the bicycle frame with the included straps.
