A new power meter looks to hit the market soon. Invented by British cyclist, Ken Norton, “Limits” power meter promises to be one of the cheapest power meters available, selling for a mere $385 (260 GBP), ridiculously cheap compared to most power meters available.
Limits is specifically designed to be affordable and within reach of most cyclists; and it’s designed to be easily interchangeable, so you can switch it between any bike easily, including your mountain bike.
How It Works
Installation is quick and easy.
Limits is attached to the bike between the pedal and the crank, and uses 4 strain gauges to measure the power being applied by the rider.
The power meter also houses an inclinometer (with a resolution of 1 degree), so it can tell when a pedal revolution has completed, so you get cadence as well. Torque data is also included.
Currently Limits only measures power on the left side, but a future release will measure power on both sides.
Limits uses Ant+ so will work with any Ant+ head unit or device. Limits is waterproof and has a battery life of 1 year, so you won’t be switching batteries out every week.
At sub $400, this power meter should bring power training within reach of most cyclists, and with the flexibility of easily moving it from bike to bike, it should be especially attractive to cyclists who ride and race across disciplines.
Limits is a crowdfunded project launching April 20, 2015.
