Cadence Speed Flow Sensor

From pumps to lights to multi-tools, Lezyne built its reputation on an industry-leading meticulousness that has never disappointed us. Now, it brings that obsession to detail to the numbers game, letting you supplement your data-gathering with the Cadence Speed Flow Sensor regardless of what brand of head unit you're running.

As its name suggest, the Flow combines cadence and speed in one lightweight, well-articulated unit. Like virtually every head unit, it speaks Bluetooth, so it's all but guaranteed to work with your current computer. Its use of a rare earth magnet helps extend the range of engagement, eliminating the will it/won't it anxiety of the millimeter spacing between sensor arm and spokes required by other sensor suites. This lets you take full advantage of the versatile mounting and adjustable swing arm, and an LED power indicator warns when the unit needs a nap.

  • A speed and cadence sensor for smart cycling
  • Rare earth magnet increases engagement range
  • Bluetooth connectivity works with most head units
  • LED power level indicator

Does the Lezyne Cadence Speed Flow Sensor work with the Lezyne Macro Easy GPS unit? The description says the bluetooth connectivity works with most head units, but does not list or describe which units it works / does not work with. Same question relative to speed and cadence sensors. Do those work with Lezyne Macro Easy GPS unit? Thanks, Rob

Nothing but trouble

I've put it through the wringer

Set up was a pain and it would not pair even when within distance specs. The computer also had issues and had to be sent back which resulted in better pairing, however, it appears that water got into the battery (it's on my MTB) and now it only pairs the cadence but not speed. Lezyene got 5 stars for customer service on replacing the computer, which I am now having issues with connecting to my computer, but says that they are out of the sensor and will not replace. UPDATE. Lezyne customer service came through and replaced the unit which is working great.

Works great, built like a tank

True to size

Solid magnet based sensor. Works great after three years, the only occasional problem I have is that my head unit seems to 'forget' the sensor after a while and needs to be re-paired. I use a wahoo sensor on my other bike and the lezyne is a more robust build.

See my review on the Flow HR sensor. These Lezyne sensors are the worst in what is, IMO, a terrible product category all around. For speed, cadence, and HR - the old $25 Cateye computers and such just dust all this junk on durability measures. I get the planned obsolescence thing, but this is out of hand.
