We publish another paper by Osman Isvan. He uses a simplified model with only 3 degrees of freedom and simulates system frequency response under steady-state and transient conditions. He investigates the effects on vibration isolation of several key parameters including tire pressure, frame compliance and riding position. The graph below from his paper, one of several, shows results when tire pressure is changed.
Osman analyzes data from over 1000 of his own bicycle rides to see what they show, and describes what might be discovered by mining the huge troves of data held by Strava, RidewithGPS and other GPS-based mapping services. Osman makes a particularly trenchant suggestion for e-bike design based on his analysis, and discusses issues of data privacy. Find this along with Osman’s other articles at https://www.sheldonbrown.com/isvan.html
Sheldonbrown.com has compiled links to more cyclecomputer and bicycle GPS manuals, old and new, than you will find anywhere else on the Internet. We have once again added information on new models and re-linked when a brand has discontinued support, left the cyclecomputer business (Blackburn, Cannondale, Pro, Topeak…), or gone out of business entirely (Avocet, Vetta…). And … if you have a manual which is not in our database, please feel free to scan it for us , or send it to us!
