PowerTap PowerCal

This is the best hundred dollars that you can spend to make you a better cyclist in my opinion. I mean, it's You know, it's a little bit more expensiv...

OK but beware... I have used these power meters for a couple years now and I have found some issues. The Powercal works fine for AVERAGE power readings but it's not quite good enough for power based interval training. Another problem is that as your heart rate drops you suddenly make less power. The...

For the money, this is a good power ‘estimator’. Unfortunately every few bike trips, the PowerCal produced a spike value (e.g. 900 Watts) any this totally mucked up my peak values and TSS scores in Training Peaks. If the designers could filter out the random ‘off the scale’ power outputs then it wou...

I use it solely for Zwift when using a dumb stationary bike at work or when traveling. I paired this with a Wahoo Cadence sensor connected to my shoe. I also use Zwift at home using a Wahoo Kickr, so have a good sense of what the full experience is like. Pros: -- Heart rate monitor works well. Compa...

I like having power on ALL of my bike rides (not just my one bike with the power meter), but the power reading from the PowerCal HR strap is overstated by 25-30% compared to my PowerTap G3 rear hub power meter. I wish there was a way to put boundaries on the power readings -- to help manually make t...

I am a less-than-ambitious cyclist, but indoor cycling with CompuTrainers got me somewhat addicted to power read-out. For my level of cycling skill and drive, spending a minimum of $500 for a power meter seemed as ridiculous as giving a Stradivarius to a 6th-grade music student. So I went for the Po...

The accuracy is fair after calibration but unless you spend a lot of time and thought calibrating with a regular power meter and an Excel spreadsheet it will struggle when used with interval training. More steady rides it can be accurate. I use it to better estimate my TSS when I am on a spin bike a...

It works on my Garmin 500 (ant+) and with Cyclemeter app (bluetooth). It does not work with MapMyRide though it connects but no data captured. I'm 60 years old and avid casual cyclist. I use the power data (ftp, power avg 3s 10s 30s, stress score, etc) as point of reference and keep updating FTP set...

I ordered a power tap as shown in my order in order to the power calculation during my cycling activities, but slI receive an item with description power cal which I use it to see if I could get the power calculation therefore the VoMax and did not work

Pretty neat concept. See DC Rainmaker for the full review. For me, it grossly underestimates wattage by 20%-40%. But great to give a ball park figure on my MTB that does not have power.
