Question 1

What was Body Rocket?

Accepted Answer

Body Rocket was a Brighton-based British cycling technology start-up, founded in 2018 by engineer and former Paralympic athlete Eric DeGolier. The company developed what it described as the world&#8217;s first real-time, direct drag-force aero measurement system for cyclists and triathletes. Unlike competing aero sensors, which estimate CdA by back-calculating from power and wind-speed data, Body Rocket measured aerodynamic drag directly via sensors on the handlebars, seatpost, and pedals. The approach was validated against wind tunnel measurements at the University of Southampton, with an average variation of 0.3%. The company never reached full commercial availability and is heading for liquidation in June 2026.

Question 2

What products did Body Rocket make?

Accepted Answer

Body Rocket developed two main products. The first was the Body Rocket System: a set of sensors at the handlebar, seatpost and pedals paired with an out-front airspeed sensor, delivering live CdA data to a Garmin head unit via the company&#8217;s AI platform, BRIAiN. Pre-orders opened in late 2024 at around £3,000. The second was a standalone, dual-sided power-meter pedal, announced in January 2025 and priced at £1,500. The pedals claimed ±0.1% accuracy at a 20Hz sample rate, validated at the Silverstone Sports Engineering Hub, which adopted them into its own pedalling-efficiency rig. SPD-SL compatible only, 185g per pedal, 40-hour battery life. Neither product shipped to consumers.

Question 3

Why did Body Rocket fail?

Accepted Answer

DeGolier told Cycling Weekly the company simply ran out of funding during the commercialisation process, between finalising the technology and bringing it to market as a consumer product. The company was £312,379 in deficit in its accounts to August 2025. Beyond the funding gap, the addressable market for on-bike aero sensors has proven consistently narrow: professional teams have the budgets but their own testing infrastructure. At the same time, consumer demand has not materialised at scale. Competing products, including the AeroPod, Notio and Aerosensor, have occupied the same niche for years without achieving mainstream adoption. Body Rocket&#8217;s system was more technically sophisticated and, correspondingly, harder to manufacture and price affordably.
