The Lezyne Micro Floor Digital Drive delivers the pumping power of a full-size floor pump with the portability of a mini-pump. It fits comfortably into a hydration pack, features an accurate digital pressure gauge, and can bring a 27.5 x 2.2-inch mountain bike tire to 24 psi in only 100 pumps. It can also inflate your road bike tire in a pinch. While it can't mount on a frame or fit in a jersey pocket as well as the Blackburn Mammoth CO2'fer or the Birzman Velocity Apogee MTB, the Micro Floor Digital Drive is far more powerful and can still fit into a moderate size hydration pack.

Our Analysis and Test Results
The Micro Floor's pumping performance is exceptional, by far the best of all the mini-pumps we tested. It only took 200 pumps to get a 27.5 x 2.2-inch mountain bike tire to 40 psi, which is far higher than mountain bike tires typically need to be. Its high score reflects this.
At only 100 pumps, this Lezyne still produced 24 psi, making it the most powerful mini-pump in the test. Unlike most other mini-pumps, the Micro Floor Digital Drive was also able to bring a 700C x 25mm road tire up to 94 psi in only 100 pumps, making this an ideal pump for both road and mountain bike use. The digital gauge is accurate to within one psi, as verified by a Topeak Smart Gauge.
Ease of Use
The Micro Floor Digital Drive is intuitive and very easy to use. As its name suggests, it's a miniature version of a floor pump. Just thread the head onto the tire valve (Presta or Schrader), swing out the handy foot brace bar, put the pump on the ground, press the digital pressure gauge button and start pumping.
When you're done, the Lezyne Air Bleed System (ABS) lets you depressurize the pump line with the press of a button, preventing air loss from the tire valve when disconnecting. The long hose is handy, as is its 360-degree swiveling base, which eliminates binding or twisting.
If you think of theMicro Floor Digital Drive as a floor pump, it is quite portable, fitting easily into a hydration pack. From a mini-pump perspective, the 30.5cm length is bulky. Especially when compared to the Birzman Velocity Apogee MTB or Blackburn Mammoth CO2'fer. It looks rather awkward when mounted on a bike frame or put in a jersey pocket, which we don't recommend.
At 242 grams the Micro Floor Digital Drive isn't very heavy for how powerful it is. It's an ideal pump for someone who rides with a hydration pack and wants a super powerful pump that can get a mountain bike tire up to adequate pressure in 100 pumps or less.
Looks and Design
Lezyne has perfected the art of making a bike pump look as good as it performs. The CNC machined aluminum construction with a polished finish is exceptionally high quality. And the digital readout gauge is low-profile and nicely integrated into the hose. The Micro Floor Digital Drive is also available in black anodized finish with gold accents, making it look even sleeker and more high-quality.
The gold anodized valve head threads nicely into the pump body, keeping the hose secured tightly. The swing-out brace on the base allows the pump to be placed on the ground and secured by foot just like a traditional floor pump. Overall, the design execution of the Micro Floor Digital Drive is outstanding.
Thanks to all-metal construction, Lezyne pumps have a reputation for durability.
The pump stanchion is not protected by a body cover, potentially exposing it to grit, grime and water. But, so long as the pump is carried in a pack when riding, this should be a non-issue. The digital gauge readout is housed in a plastic body, so a little extra care is needed there. For those who treat their equipment a little on the rough side, the Micro Floor Drive can be ordered without the digital gauge.
The Micro Floor Drive is best suited for mountain bikers who ride with a hydration pack. If you don't mind carrying a little extra bulk in exchange for class-leading pumping performance, this may be the pump for you. Thanks to its high-pressure road tire capabilities, the Micro Floor Drive can serve as a very portable floor pump for your car. It can even serve as a capable hand pump in dirt bike motorcycle applications.
With an $84.99 MSRP, the Micro Floor Digital Drive is on the expensive end of the mini-pump spectrum. But its high performance, road or trail versatility, and compact package make it worth the extra money if you carry a backpack.
The Micro Floor Drive is an outstanding mini-pump for a wide range of applications. It is the most powerful mini-pump in the test and is rather compact and lightweight given its capability. The accurate digital readout ensures proper tire pressure and saves time when pumping. The fact that it can serve for both road and mountain bike tire duty is a nice bonus. For those who wear hydration packs and want the most powerful portable mountain bike pump, the Micro Floor Digital Drive is our top choice.
