Huron Cycling presents at BMD Conference
Huron Cycling participated in the biannual Bicycle and Motorcycle Dynamics conference in Delft, The Netherlands, from October 17 to 21, 2023. Cofounder and inventor Willem den Boer presented a paper with the title "Improvement of Cycling Efficiency for Drivetrains with Elasticity". The presentation and the peer-reviewed full paper from the Proceedings are in the download section below.
Patent granted on IMPACT crank set with Spring Action
A US patent was granted for the bicycle drivetrain component with improved efficiency developed by Huron Cycling LLC. US Patent 11,142,281 describes the IMPACT crank set which has spring action comparable to recent record-breaking running shoes. Contrary to conventional crank sets, the crank arms are not directly attached to the crank spindle, but can rotate by up to a few degrees, counteracted by fiber-composite springs inside the hollow crank arms.
Depending on riding style, the IMPACT crank set improves cycling efficiency, especially when going uphill or accelerating, by reducing the effect of the dead spot during the pedal stroke.
The corresponding European patent has been granted as well.
The IMPACT crank set can be combined with the IMPACT two-sided power meter based on inexpensive sensors rather than strain gauges.
Earlier US Patents 9,403,576 and 9,809,275 described prototype, proof of concept versions of the crank set and power meter.
Huron Cycling partners with bicycle and component manufacturers to bring its technology to the market.
Huron Cycling issues a White paper on measurements with their unique power meter using inexpensive rotary sensors rather than strain gauges
The paper by Eastern Michigan University entitled: "Novel Crank with Elastomer Spring Improves Effective Power in Trained Cyclists and Triathletes" is published in the Journal: Medicine & Science in Sports & Exercise. It shows test results of the improved cycling efficiency in an earlier prototype of Huron Cycling's IMPACT crank set.
Huron Cycling issues a White paper with results on the testing of their lightweight IMPACT drivetrain. More than 4 % improvement in cycling efficiency is measured for a range of power and cadence levels.
Eastern Michigan University completes testing of Huron Cycling proof of concept drivetrain. Results demonstrating improved cycling efficiency will be published and presented at conferences during 2018 and 2019
