|The Axis intelligent bike crank uses some clever electronics and load cells to cyclically measure various loads on a bicycle crank. Software then converts this data into information allowing trainers to monitor and adjust the riders' technique for improved performance. It effectively turns a cycle or ergo into a dynamometer.
Creative CAD continues to assist with the ongoing development of this product, and has developed a test rig which applies a constant force to the crank as it rotates and includes in the computation the crank drive flex. The force is applied with a fluidic muscle which allows a large force to be applied using low pressure air, ideal for safety in the sports laboratory.
