Personalized Virtual Non-round Bicycle Chain-rings using Live Optimization While Pedaling


The TrueBike, a cycling trainer that mimics the forces felt when accelerating, grade changes, and wind drag.

Overall objective: Personalized non-round chainrings based on real-time optimization of the shape of a (virtual) chainring

Research options:

  • Collect, review, discuss available research of non-round chainrings
  • Establish a penalty function that would have to be minimized during the optimization. Penalty function can be related to muscle activation, speed variations, multibody analysis, etc
  • Develop an optimization algorithm that modifies the chainrings whilst cycling
  • Develop a measurement protocol to find the optimal chainring for an individual. The form of the chainring will influence fatigue and muscle contraction speed, leading to new optimal chainrings

How to Apply

Send an email to j.k.moore@tudelft.nl with the title of the project in the subject line. Include an approximately half-page motivation letter explaining why you want to work in the Bicycle Lab on this project along with your current resume or C.V.
