Senior technical writer

Simon von Bromley is a senior technical writer for BikeRadar, and a regular contributor on BikeRadar’s podcast and YouTube channel. Simon joined BikeRadar in 2020, but has been riding bikes all his life, and racing road and time trial bikes for more than a decade. He’s also developed a keen interest in gravel bikes and riding off-road in recent years. As well as covering news and trending topics in road and gravel cycling, Simon writes in-depth reviews and features on power meters, smart trainers, aero tech, and nerdy topics such as chain lubricants, tyres and pro-bike tech from races such as the Tour de France. He has a keen interest in any tech that can help him (or you) ride faster and is obsessed with the tiniest details. Before joining BikeRadar, Simon worked on the picture desk at BBC Studios and as a freelance writer and photographer. He has had work published on Cyclingnews.com and in Cycling Plus magazine.
