A tilting, narrow-track, recumbent trike with user-controllable stability.



The UWM Research Foundation presents a tilting, narrow-track, recumbent tricycle with variable stability combines the best of upright bikes, recumbent bikes, and recumbent trikes to eliminate the drawbacks of each and avoid the pitfalls of other existing tilting trikes.


Intellectual Property

A US provisional patent application was filed in winter of 2019.

This award-winning technology (“Innovation Award” at ASME’s HPVC hosted by Michigan State University, April 5-7, 2019 and First Place, Undergraduate at UWM’s CEAS Engineering Research Poster Competition, April 27, 2019) is part of an active and ongoing research program and is seeking partners to develop more of the final product. It is available for developmental research support/licensing under either exclusive or non-exclusive terms.
