The keirin event was definitely lacking something at the UCI Track World Cup round in London at the weekend: the hum of the derny pace bike's motor and accompanying smell of exhaust fumes.

To the upset of many track purists, the UCI unveiled its new electric derny bike in the Lee Valley velodrome over the weekend. The virtually silent, zero-emissions bike marks a break in a decades-old tradition of petrol-engined pace bikes, and some detractors have said its absence in London changed the atmosphere of the keirin races completely.

Nigel Wynn
Former Associate Editor

Nigel Wynn worked as associate editor on CyclingWeekly.com, he worked almost single-handedly on the Cycling Weekly website in its early days. His passion for cycling, his writing and his creativity, as well as his hard work and dedication, were the original driving force behind the website’s success. Without him, CyclingWeekly.com would certainly not exist on the size and scale that it enjoys today. Nigel sadly passed away, following a brave battle with a cancer-related illness, in 2018. He was a highly valued colleague, and more importantly, an exceptional person to work with - his presence is sorely missed.
