Great value

Got it at very affordable price. Easy to install, calibrate. Did few outdoor ride and Zwift session, it work just great! Highly recommended.

Great product

Everything works well, Data are precise, no drops out, Extremly fast shiping to Slovakia (2days) 100% recomended


Easy to fit easy to setup. Works very well. Data collection seems to be nice and stable to both Strava and Garmin. Great product and great service would recommend both probikekit and 4iiii power meter crank to anyone


I have no problems with 4iiii after 2 months of use. Highly recommended.

great PM for the money

got on offer a few months back. great PM and very easily swappable if you run Shimano cranksets on all bikes as i do. never misses a "watt" and is comparable in power output to my Vector S. we'll see what its like in the next few months with lower temps, etc but all is good so far. had a question for support re calibration and they reverted very quickly.

My 4iii

Nice piece of kit, delivered promptly as always from "pbk" . Very easy to install and set up - very clear instructions. Still getting used to the results and numbers - it's going to take awhile to figure it all out!! A very good value power meter with which to start training with power!

Perfectly sensitive and precise!

Tested on various strava segments and impressive to see how accurate it is. Without doubt my best purchase of 2016!

Excellent. Accurate and simple to install

Very impressed. My first power meter and I was a little weary it'd take some time to fix/install and pair up with my garmin 820 which I bought also with probikekit. It was simple, literally attached the left crank arm, searched devices to pair and found the power meter, then rode!
