An interactive app for designing and testing virtual bicycle wheels. Choose your wheel parameters, add forces like rider wight and pedaling torque, and plot deformation and spoke tensions.

Sophisticated stress analysis

Results are based on a mathematical model of the wheel that takes into account the effects of spoke tension and rim compression. The model properly predicts the "softening" effect of excessive spoke tension: the lateral stiffness of the wheel is reduced due to the compression in the rim.

Library of rim properties

The stiffness properties of a number of rims have been measured using the acoustic method developed by Matt Ford and Patrick Peng. You can select one of these pre-defined rims, or define your own by setting the bending and torsion stiffness manually.
