Body Rocket, the UK-based startup and creator of the self-titled Body Rocket System, has at present launched a pair of energy meter pedals which it claims to be probably the most correct energy meter on the planet.
They declare an accuracy of +/- 0.1%, run through ANT+, and boast a pattern price of 20Hz.
They have been designed as a part of the simply-titled Body Rocket System, which is a quartet of parts that mix to offer real-time drag information, or CdA, when driving on the street or monitor.
That System includes an air-speed sensor on the entrance of the bike, two weight sensors beneath the saddle and the bottom bar (it is presently designed for time trial bikes, though a roadgoing prototype does exist), in addition to the facility meter pedals. And collectively, they calculate real-time CdA, which will be despatched to your head unit, or captured for later evaluation within the Body Rocket app.
The crew had initially supposed to make use of an aftermarket energy meter, however realized it wanted one with a better studying frequency (the hertz, or how typically it measures your energy output per second) and extra accuracy than was presently obtainable in the marketplace.
The greatest energy meter pedals obtainable common at round an accuracy of +/- 1%, with a hertz studying of round one (1hz). And so, within the model’s personal phrases: “We designed probably the most correct energy meter on the planet.”
That declare is backed up by the engineers at Silverstone Sports Engineering Hub, a cycling-specific testing facility within the UK which homes a wind tunnel, rolling resistance rig, and a pedalling effectivity rig – as utilized in our street tyre lab check – which depends on the Body Rocket pedals for its information.

The model did not initially plan to launch the pedals as a standalone product, however following vital client curiosity proven in them through the launch of the general System, the model pivoted its strategy.
They will likely be priced at £1,500 (International pricing tbc), and delivery will start in June 2025. They can then be upgraded to the entire System at a later date, ought to the person want.
They weigh in at 185g per pedal – 68g greater than a normal Shimano Dura-Ace pedal – and are Shimano SPD-SL suitable solely. They have an in-built rechargeable battery, and declare a 40-hour life between fees.
The ‘pod’ which homes the electronics and sensors is positioned consistent with the crank arm reasonably than towards it, and so the Body Rocket energy meter pedals function a normal 53mm spindle, which means Q-factor is unaffected.
