Body Rocket AI-powered, real-time wind tunnel substitute available for pre-order

Body Rocket, the world’s first ‘real-time’ aerodynamic direct drag force measurement system, has surpassed its goal on the funding platform Kickstarter. It reached the $28,500 target less than two days after the Brighton-based tech startup announced that pre-orders for Body Rocket were live.

Cycling Weekly first covered the system two years ago, when the initial wave of crowdfunding began. After further development, the system is now offered in a range of packages that start at £2,950. For an extra £2,000, you can receive personal training from Alex Dowsett and other ‘bonuses’ featured in the Dream Team bundle. Dowsett, arguably one of the finest TT riders of his generation, was an early investor in Body Rocket.

Body Rocket’s USP is that it offers cyclists of all levels real-time CdA (coefficient of aerodynamic drag) rather than using estimates to calculate this number. It achieves this via a system that uses four sensors on the bike, located between the handlebar and stem, between the seat post and saddle and at both pedals. Combined they capture 47 measurements and 28,000 data points every minute. The dual-sided power pedals, which have a claimed accuracy of 0.1%, are currently being used at the Silverstone Sports Engineering Hub.

“Every single day is like being in a wind tunnel,” says Kristian Blummenfelt, Olympic and Ironman champion and Body Rocket investor, of the system. He credits Body Rocket with ​​saving him 35 watts over 40km on his road bike, as well as 30 Watts in his TT position.

And here is another of the system’s key selling points. Most amateur cyclists don’t have the luxury of being able to visit a wind tunnel. But by having the sensor fitted to the bike at all times, users are collecting aero data every time they ride. And, unlike a wind tunnel, the numbers are delivered straight to the cyclist’s head unit, rather than having to be first interpreted by a professional.

To aid this, Body Rocket has developed its own AI-driven software, called BRIAN (Body Rocket Individualised Ai Network), which it says “ guides users through the process and helps them track their progress over time, without them…
