Abstract
A system for sensing velocity of a wheeled vehicle has a flexible arm connected to a speed sensor and wireless transmitter at one end and to an adjustable strap or clamp at the other end. The strap is attached near the wheel to be measured. The sensor can then be positioned via the flexible arm to a location immediately adjacent the wheel. There is also a display unit connected to another strap or clamp. The display unit contains a wireless receiver that receives the data transmitted by the transmitter on the sensor, and a microprocessor that calculates the data and displays it for the user to view. A magnetic strip is attached directly to one of the wheels of the device. As the wheel rotates, the magnetic strip passes by the sensor positioned adjacent the wheel, and this passage is recorded by the sensor.
