The Lezyne Alloy High Volume Digital Drive floor pump is a very well-constructed, high-quality item which is a joy to use. It’s not the highest volume pump, but it does strike a good balance between covering a reasonable maximum pressure whilst being able to inflate tyres quickly. The pump head is a little fiddly to use, and there is no way to release pressure using the pump, but the gauge is a great size, and the stability is excellent.

Lezyne Alloy HV Digital Drive floor pump – Technical Details

The Alloy Digital Drive floor pump is designed for precise, high-volume inflation using a host of high-quality features.

Starting with the body of the pump, the oversized high volume barrel is constructed from aluminium, whilst the piston is made from steel for increased durability. The handle is made from a varnished wood handle with an aluminium T-junction and uses a slightly tapered shape for ergonomic comfort.

A three-pronged footplate keeps the pump stable, providing space for a foot to secure it during use. The middle prong mounts a large 3.5” digital pressure gauge with switchable measuring units between PSI and BAR. This gauge utilises a readily available CR2032 battery, which is easily replaceable when needed.

At the business end, an extra-long 125cm nylon reinforced braided hose leads to Lezyne’s ABS-1 tubeless pump head. This head is designed for Presta valve inflation and features an adaptor to inflate a Presta valve with or without the valve core fitted. This is intended to help seat tubeless tyres with the valve core removed for maximum flow.

The pump is available in two colourways with the barrel in a satin black or raw aluminium finish.

Lezyne Alloy HV Digital Drive floor pump – Performance

Using the pump head is a little fiddly, requiring it to be screwed on to the valve rather than other designs that use a lever to lock it on the valve. With some valves, I’ve found unscrewing the pump head after use brings the valve core out with it, resulting in the tyre losing all its air, which is frustrating. This issue is lessened by remembering to use the air release button on the pump head before unscrewing it.

This button releases the pressure from the pump head/hose but not from the tyre and helps ensure the pump head separates from the valve core correctly. A point to note, there is no way of adjusting tyre pressures down, or releasing pressure, with the pump connected, so make sure you don’t overinflate.

The pump itself is very well made, it’s a lovely thing to use with a tactile wooden handle and a very solid feel. It’s not heavy, but it has enough weight for it to feel like it’s a durable and sturdy build.

The large gauge is accurate and precise to 1psi, however, the placement does mean it’s quite far away during use, and some people may find it hard to read. In glaring sun, it can be a little difficult to read the screen, but under normal conditions, indoors or in the shade, it’s a clear and crisp read-out.

This pump is marketed as a high-volume pump, however, in this class, although the pump action feels efficient and effective, I’d say it's not a big blower. As a metric for the airflow, a 29” 2.5 tyre was inflated from 0 PSI to 22 PSI in 24 pumps, so it's by no means slow. I've had mixed luck trying to seat tubeless tyres with this pump. It requires a very fast pumping action to get the tyres' beads up enough to start sealing, with some tyre/rim combinations, this works, and others it doesn't. The pump would benefit from more volume to be able to reliably seat tubeless tyres. 

With a max pressure of 100psi, it strikes a good balance between being useful for all bicycle tyres whilst retaining a decent air flow.

It's not a bulky item, so it's easy to stow away in the garage/shed, and for me, it lives in the van, not taking up any notable room.

Lezyne Alloy HV Digital Drive floor pump - Verdict

Retailing at £120, this pump feels like a top-quality product, but it is on the expensive side when considering other offerings on the market.

A favourite of mine is the Specialized Air Tool MTB floor pump that retails at £85. This is a cheaper build than the Lezyne and has a max pressure of 75psi (gauge reads to 40psi), however, it’s a true high volume pump, which is fuss-free to use.  

At the other end of the market, for £37, the Topeak Joe Blow Sport track pump is worth considering. It doesn’t have the high volume capability to seat tubeless tyres, and it’s a much cheaper, plastic-based construction, but it received praise for its value for money.

The Lezyne Alloy High Volume Digital Drive floor pump proves to be a smooth operator, as a beautifully constructed pump. Although the head is a little fiddly and it's not the highest volume pump, it does strike a good balance between a useful maximum pressure whilst inflating tyres quickly. The gauge is clear and crisp in all but the sunniest of conditions, and it’s slim enough to be stored in the shed/car without taking up too much room. It’s not cheap, but it’s a solid performer, and I have no concerns it’ll last.
