Measure Power with 1-Degree Precision Bluetooth Bicycle Wheel & Pedal Sensor

Share Article

The new VeloComputer Sensor version 3.6 is on the cutting edge of precision in cycling sports performance measurement. It continues its history of innovation, combining accuracy in wheel rotation measurement with integrated cadence sensor. The revolutionary VeloComputer dual sensor accurately measures distance, spot speed, acceleration and cadence allowing VeloComputer mobile application to calculate propelled power and other performance data.

SoundOfMotion released version 3.6 of its series of 1-degree precision VeloComputer Bluetooth bicycle sensors. The sensor uses classic Bluetooth available in most mobile phones, transmitting performance cycling data to the VeloComputer mobile application. The sensor is designed for mounting on a rear wheel along the chainstay of a bicycle and combines wheel and pedal strokes sensors in one unit. The sensor accurately measures wheel rotation within 1-degree accuracy and cadence from the pedal motion.

SoundOfMotion's innovative wheel sensing technology is at least 360 times more accurate than traditional cycling computers. The VeloComputer wheel sensor detects a magnetic field from a magnet attached to the wheel and determines the angle of a rotation with 1-degree accuracy. A pair of smaller magnets can be mounted on opposite sides of a wheel, amplifying the magnetic field and also balancing the wheel. This 1-degree accuracy reduces speed latency from 7 seconds in traditional bicycle computers to less than one second. This low latency allows VeloComputer to accurately determine a spot speed and acceleration, which is used to calculate torque and propelled power on the wheel. Spot speed, acceleration, cadence, propelled and applied power are critical for cyclists to improve their training and race technique.

The VeloComputer Sensor version 3.6 is compatible with most Bluetooth 2.0 mobile devices supporting serial port protocol - SPP. It uses a rechargeable battery, charged via micro USB adapter. The sensor was originally designed for road and trek bicycles for its high accuracy and simplicity but can also be mounted on other types of bicycles with customized mounting brackets.

Orders can be placed directly at http://www.velocomputer.com with the first batch delivery scheduled in July 2010. The price for the sensor is $199.
