Lezyne Tech Drive HV Hand Pump

This is a great design fits in the bottle shaped bag and will pump 100+ road tires. I cant think of anywat to make this better. I guess if it had the aspect where you could pump less air but more easily as in some pumps it would be even better but it is not supper hard to get in the less 20-40 strokes to reach 100

I purchased this pump for my Surly Troll with 2.5 x 26-inch tires. They run 60 PSI on the road. I continue to use tubes on that bike, and this pump has worked well for me. For mostly environmental reasons I resist using CO2, so with some patches, an extra tube (or two), and this pump, I'm confident that I'll get myself home from almost anywhere, under almost any circumstance. No flying on a wing and a prayer.I've used this pump in the dark without a problem. It takes approximately 100 to 150 strokes to get my tires to 50 or 55 PSI. It's well built out of quality materials and attachs under the water bottle cage, well out of the way.This pump worked so well for me that I've purchased a second. This one is a life-saver of sorts: in case one of the (tubeless) tires on my Surly Pugsley rolls off a rim in the middle of nowhere. I carry an extra tube and this pump. I don't look forward to inflating a 4.3 x 26-inch fat tire with any hand-pump, but I have every confidence that this little pump will be up to the task when duty calls.You can find lighter pumps no doubt, but none better made or more attractive, IMO.Happy customer here.

I haven't (fortunately) had a chance to use this pump, but it looks like a quality product. The purpose of this review is to comment on the mount, and Lezyne customer service. The mount is plastic, and broke after a few weeks. Probably not the fault of the mount as I hit a branch, but it was very easy to break. So I went online to Lezyne and ordered an aluminum mount. The one I ordered was listed as an accessory right under the listing of the pump I have on their site. So I sent them an email on July 6th, requesting a return and replace or whatever BUT now it is July 18th and I did not receive a response to my email. So I went back to their site and tried to send a second email, but the stupid "Capcha" provided me with a blank screen so I could not send the email. Very frustrating. I will next try a phone call, but too much went wrong here. I would rate the pump itself as good, but the mount and customer service poor. AND their website is misleading. Why list an accessory under a pump when it doesn't fit the pump? So far $18 wasted on a mount that doesn't fit.

This pump has a variety of characteristics that all add up to be the best trail pump I’ve ever used for mountain biking. #1: the pump produces a very high volume making it extremely efficient for its size, #2 the presta end of the hose is threaded vs press fit making the connection very secure, #3: it has a flexible hose to alleviate damage to valve stems, #4: the hose storage yields the pump compact enough to store in a pack.

This little pump is fantastic. I bought it last year to have in case I flatted and didn't have any CO2. That happened this morning. I really didn't expect much from a pump that small, but I thought however hard it was to use it would be better than walking. What I discovered was that the pump works so well it is almost as easy to use as my floor pump. I pumped my 29"x2.3" MTB tire up to about 30 pounds pressure in just a few minutes. I was just blown away by it. I've used several different small pumps in the past and had came to view them as a "last resort only." This little pump is definitely a "Keeper".

I ride a hybrid bike with my tires at at least 80 psi. This is rated as high as 120 psi according to the website, but getting it past 70 psi required far too much effort for this pump to be used consistently. Now don't get me wrong, Lezyne makes great pumps, but this one just didn't cut it for my needs on my hybrid. If you need to get your psi above 80 i would just get their line of road bike pumps which i had ordered in the past. I have the road drive pump for my road bike. That pump is legit and still made by Lezyne. The reason i wanted another pump was because the one i have is white and my bike was black and i wanted something to complement the color scheme. I'll either just get a bracket to hold my other pump or just get another road drive in black instead. But don't be dissuaded by Lezyne pumps, they are still top quality pumps.

Lots of small innovations and well-thought-out features in a functional design.Pros:-Easy to switch between Presta and Schrader valves with dedicated connectors for each.-Positive threaded connection (no leaky lever-operated connectors).-Flexible hose protects valve stem.-Fairly light weight.-Moves a lot of air.-Pumping is still practical at 50 psi (I didn't try it above that level).-Rubber caps that protect threaded connections are attached to the pump, so one needn't worry about loosing them.-Pressure relief button reduces friction when disconnecting from Presta valves. Seems unnecessary with Schrader valves.Cons:-Barrel gets uncomfortably warm. Can be cooled with water or just by waiting.Comments:-frame attachment bracket seems secure, but I've not tested it hard yet.

A quality product. Does the job but with great difficulty. Years ago, as a young person in England, pumps came with bikes. They were easy to use and had a long stroke. Modern pumps have short 4" strokes which is ridiculous (but this one is better than the two I bought at the bike shop.) Still, it takes a body builder to use it. I bought it for my fat bike because it's high volume but haven't tried it on a flat fat tire, yet. I tried it on a regular bike tire and was shocked at how much effort is needed to bring the tire up to pressure. I may have to go to CO2 inflators because Florida summers would be a disaster if I had to deal with a flat miles from home.

I haven't had to use the pump yet but seems good quality, nice and small and compact.

Excellent quality product really well made will last for many years of that I'm sure very and quality engineering highly recommended.

Wonderful small thing, easy and comfortable to use.

I have always struggled with presta valves. This pump works like magic.

Its a good enough product, but its VERY expensive for what it is. I was expecting something extraordinary from Lezyne but its just nicely made and not anything special. Glad it wasn't for me but ordered for a friend. Probaly worth ten or 12 quid. These guys might make some special stuff, but as a first Lezyne purchase this left me feeling underwhelmed and slightly ripped off. Meh.
