For most riders there are two main limitations to getting started with a power meter: cost and compatibility. Step forward the F aptly named Limits BIA, which sits between your pedal and crank and can therefore be fitted to any bike regardless of crank, bottom bracket and pedal type. And at £229 it's also one of the cheapest power meters if not the cheapest - on the market.
With a claimed power accuracy of +/-2%, the BIA is a small, circular plastic and carbon-fibre device with metal pedal/ crank threads. It is single-sided only.
Measuring 42mm in diameter and 18mm thick, an 18mm spacer is included to add between the right pedal and crank to balance out the increased Q-factor between each side for a total increase of 36mm on a typical 150mm-wide road bike.
Total weight is 97g including two SR44 coincell batteries (included) and the driveside pedal spacer - close to the extra weight of some pedal power meters. Battery life is a claimed 80 hours. Waterproof rating is IP54, meaning it has protection from "water splashes" so it's unlikely to stand up well to winter or off-road riding.
Set-up
Fitting the plastic battery covers using a coin is a little tricky as it's not that easy to see or feel how well lined up they are and there's not a firm end point.
Limits says it has designed the cover to break if it's overtightened and two spare covers are included.
