Review: Lezyne Digital Pressure Drive

The Lezyne Digital Pressure Drive is a compact and precise pump to dial in your pressure. Unfortunately, the head design risks taking the core out of your valve, and going over 80 psi requires Herculean effort – so best suited for gravel or mountain bikes.

It’s a pretty feature-rich pocket pump, with that built-in digital gauge allowing you to get precise pressure, with readings in either psi or bar.

The set looks and feels like quality with its anodized finish and CNC machined metal parts. At 128g it’s not exactly light, with the gauge adding around 50g over the small standard 170mm Pressure Drive pump.

If you want to hang it on your bike, there’s a bottle cage mount with a Velcro strap and a metal buckle that keeps the pump sturdy.

pipe and head

The flexible hose to connect to your valve has a Presta head on one end and a Schrader on the other. The Presta end has a button that can be used to remove pressure from the hose before unwinding from a valve after inflation – although I didn’t really notice much of a difference when removing the head, pressurized or not .


When inflating Schrader valves, the button can also be used to bleed air if you are over the target. It is also possible to bleed a small amount during Presta inflation if you press it lightly.

The hose stores neatly in the handle and each end has its own little rubber stopper. These have been known to go missing, but luckily a spares kit including all rubber o-rings is available.

The Lezyne’s head is threaded, unlike the Snap-It Apogee used by competitor Birzman which shoots straight, so there’s no risk of unscrewing a Presta valve core – a very real possibility with the Lezyne. To reduce the risk, Lezyne has machined core-sized notches into the sides of the Presta end of the hose, so you can tighten your valve core before threading the hose. I found the easiest way to install was to first thread the hose onto the Presta valve body and then attach the pump – you can’t do this with Schrader valves because the Hose head installation reduces air release.

Gauge

Turning the gauge on and changing the scale from psi to bar is done by pressing the button, as is turning it off. If you forget, it automatically shuts off after three minutes.

If you think the gauge is reading, you can reset it by pressing and holding the button for 10 seconds – probably a good idea after major weather changes, flying or climbing or descending from a mountain, 1000m equals about 3 psi difference.

I found the accuracy of the gauge to be within a few psi of my other digital gauges, so good enough for roadside use, and certainly much more accurate than the Mk I Human Thumb-O-Meter.

The replaceable CR1220 battery is accessible via a threaded cover with an O-ring to keep moisture out.

Pump action

Holding the pump body is fairly easy, with the volume of the gauge adding to the grip. Eventually the end of the metal hose gets hot, so the gloves may be more comfortable when looking for higher pressures.

On a fairly common 28mm 700C tire, it took 100 easy hits to hit 40 psi. Another 50 hits reached 60 psi, and the strain was becoming noticeable. Getting to a fairly typical 80 psi took another 50 – so 200 total – and by then the effort required was pretty darn hard. I definitely wouldn’t want to go above 80 psi, so the pump rating of 120 must be for Olympic lifters.

This leads me to believe that the Digital Pressure Drive is better suited for mountain or gravel bike applications, and indeed Lezyne offers a 160 psi Digital Road Drive which is longer and narrower, reducing the effort required to move less air over a longer stroke.

When it comes to inflating ATVs, probably the most common use would be to refill a soft tire. On a fairly common 2.8-inch 650B tire, going from a spongy 16 psi to 25 took an easy 160 strokes. On a 3-inch 29er monster, I went from 15 to 20 psi in 90 strokes—again, it’s all easy to do, and the digital gauge made it easy to shut off when needed. While pumping, the gauge dances over a few psi, but you still have a pretty good idea of ​​where you are. Once you stop, it installs in seconds.

Value and conclusion

As far as I know, Lezyne is the only company that makes a digital gauge pocket pump. Steve wasn’t too impressed with the cheaper analogue Crank Bros Sterling Pumpdifficult to use and difficult to put under pressure.

In comparison, I really liked (and still do) Birzman Mini Apogee which has both a hose and an analog pressure gauge, as well as the superb risk-free Snap-It Apogee head. While an analog pressure gauge will be harder to read and arguably less accurate, the pump costs just over a third of the price and won’t take your valve core with it. (Read my review here.)

Overall, I like the Lezyne Digital Pressure Drive Pump. It’s easy to see where you’re at mid-pump without stopping to check, and the CNC-machined and anodized hardware is very well made. Just be aware of the need to keep your valve cores tight, and that 80 psi is about your limit.

Verdict

Good for hitting precise pressures on your gravel or mountain bikes, but hard work for road pressures

This is a great pump for ATV and gravel users, who want precise pressures under 60 psi.

Lezyne says, “Portable precision is the name of the game with the Digital Pressure Drive. has never been so easy. .

“Optimized for rapid inflation at medium to high pressures, the Digital Pressure Drive is rated at 120 PSI. Its flexible ABS hose is compatible with Presta and Schrader valves and features an integrated valve core tool.”

The build quality is excellent.

Rate the product for its performance:

7/10

Works well up to a point. It is quite difficult to go higher than 80 psi, which is a disappointment in a pump advertised at 120.

Rate the product for durability:

8/10

Always looking new, but questionable rubber cap retention over time.

Rate the product by weight (if applicable)

It’s not that light, but hey, digital.

Rate the product for comfort (if applicable)

6/10

When pumping, you really want to wear gloves, but it’s hard to see how they circumvent heat issues.

Evaluate the product for its value:

5/10

For accurate, pocket-sized digital measurement, it’s pretty much the only game. Analog options cost a third of the price, though.

Tell us how the product performed overall when used as intended

Excellent up to about 60 psi, which sorts mountain bike and gravel well. Beyond that, not so much.

Tell us what you particularly liked about the product

Speed ​​and accuracy of measurement.

Tell us what you particularly disliked about the product

The threaded pipe head.

How does the price compare to similar products on the market, including those recently tested on road.cc?

There’s no digital pocket comparison, and it’s three times the price, or more, of analog alternatives.

All in all, I’d say it’s good – I’d prefer a header to pull off, and it’s also a good old money shot, and not light, but it works well in anger.
