Favero Electronics manufactures the bePRO power meter pedals, a pedal-based power meter. The bePRO is a dual-sided system with a power meter located on each pedal and takes power from both legs in order to determine total power. The bePRO S is a single-sided pedal and takes the force that is applied to the left pedal only and doubles it to get total power. Note that you have the option to buy a right side pedal with power at a later date, in order to have a dual-sided power meter system.The power meter provides power from 0 to 2,000 watts and cadence from 30-180 RPM.
Admittedly, installation of the bePRO power meter isn’t as simple as PowerTap’s P1 pedals (which can be installed with just a hex wrench), however once you give the instructions a glance and have the parts laid out in front of you, it’s really not very hard. In fact, many report being able to install the pedals in under 5 minutes with a little practice.
The sensor weighs in at only 16 grams, while the total weight of each pedal is 156 grams. This makes the power meter one of the lightest pedals on the market.
Left/Right Power Measurement
Since the bePRO power meter locates a power meter on each pedal, it can measure true left and right power. While some power meters provide an estimated left/right power figure, only a few can provide independent left/right data.
The power meter uses rechargeable lithium-ion batteries.
Battery life is right around the 30-hour mark. 4 to 6 hours before the battery is completely discharged, the bePRO will send a ‘Low Battery Message’ to the head unit.
Difficulty to Change
The battery is guaranteed for the life of the power meter and does not need to be changed.
The pedals transmit data via the ANT+ wireless protocol which means they are compatible with the majority of head units on the market, including Gamin units. Note that in order to get left/right data, you will need a head unit that supports this functionality. The majority of head units produced in the last few years do so.
The pedals are accurate to within +/-2%. This is on par with the majority of power meters on the market.
To measure cadence, most power meters use either a magnet (which is attached to the bike frame) and a reed switch, or an accelerometer (a device housed inside the power meter which measures proper acceleration). In the case of the bePRO, an accelerometer is used.
The bePRO power meter features both static as well as dynamic (moving) calibration. Favero suggests you perform a static calibration before each training session or after pedaling for a few minutes so as to adjust the pedals (mechanically and thermally). Dynamic calibration allows bePRO to precisely check the mechanical alignment of the pedals. It should be performed after each new installation and can be periodically repeated to ensure maximum precision.
The bePRO comes with a standard 2 year warranty which covers conformity and factory defects which already exist on delivery to the customer and does not include defects caused by incorrect installation or improper use.
The Q-factor for the pedals is 54 mm. This is the same Q-factor as LOOK Kèo pedals so you don’t have to worry about your Q-factor changing.
