An affordable power meter worth a look

Just self installed one on my Canyon, only had a smart trainer to compare it against but the average figures for a 30 min ride with ERG off were within a few watts.

The numbers are baffling, A crank source versus wheel on trainer source complicate it for a start. Everyone has their variations, who’s is the benchmark :man_shrugging:t2:

Figured £225 and install it myself was a good call for me as a leisure cyclist who certainly can’t justify paying 2 or 3 times that for the big names, who may or may not be any more accurate or last any longer.

Online chat was quick to respond, and they were available on the phone too.

No more disqualifications on zwiftpower for me for using ZP :blush: and can use it in the real world too - unlike a smart trainer (although a smart trainer with resistance control is also ideal for zwift).

Give them a look.

Did you have any trouble the power meter pairing with Zwit?
Tried to use my Vector 3 power pedals with Zwift today. The pedals paired ok and registered power but the Zwift speed sensor would not pair?

You don’t need a speed sensor if you’re using a power meter. It says on the pairing screen “Power Source” OR “ Speed Sensor”

Did you have trouble pairing the Avio Powersense sensor to zwift? I just got mine installed and calibrated, but after multiple tries it won’t connect to zwift. I’ve reached out to avio but they haven’t replied. Did you do anything in particular to get it connected? Thanks

Not that I recall. You have to tap it to get it to turn on, but once it’s on it should be found. I’ve not used my bike for a while, but from memory out on the road it was slow to connect to garmin - my “taps” as per the instructions maybe weren’t “sharp” enough.

Thanks for the quick reply. I tap to wake every time before I connect so I don’t think thats the issue. Did you by chance use a laptop as your platform for Zwift?

Yeah, my Zwift is usually on a laptop.

When I’m home tonight I’ll try it on the iPad/iPhone with the power meter (assuming my battery hasn’t corroded with lack of use or changing). Sure I’ve got some free Zwift miles.


Hi again,

I can’t tell you regarding the computer as I have a tacx, my new laptop doesn’t appear to have a driver for the m-usb ant+ stick I used before with the dumb trainer and I can’t find one online.

In device manager it’s got a :warning: and on Zwift it was only searching Bluetooth.

It wouldn’t connect to my garmin. Changed the battery, no joy, pulled the battery and put it back in and farming found both the tacx and powersense - I couldn’t connect as the bike is on the trainer and the two devices are too close to each other.

I’d check the ant+ stick on the laptop is functioning.


Update - searching the wiggle questions for my lifeline ant+ m-usb, someone suggested installing garmin express which will install drivers. It worked. Zwift was searching for ant+ and Bluetooth and found the power meter.

Hey Alan,

Ahh I see, so basically it would only connect to ANT+?
I have a macbook pro (no ANT+ installed) so I guess I’d have to buy the ANT+m-usb then?

Thanks again

Yeah it’s ant+

Also, to calibrate it (although it was pretty spot on) you need an android phone as there’s not an apple app. It involves hanging a 10kg weight off the pedal.

I’ve just got the lifeline ant+ mini stick from wiggle £20, worked fine, even with laptop on a worktop in front of the bike wheel (couldn’t put wheel under it as there were cupboards). It’s range was fine, never had any dropouts.

I see, this clarified a lot for me and saved some headaches. Thanks for all the help, Alan!



No problem :+1:t2:

Enjoy comparing single sided power v total power and the discrepancies between devices.
