LezynePressure Drive Hand Pump(Return to Product Page)

This pump,fits my bike. My only issue is it's size. Any larger would not fit my bike. So the issue is my limited space on my bike not the pump. The pump works well. No complaints.

The pump is light and fairly efficient for a bike pump. The nozzle is connected to a hose and the hose screws into the pump. The hose then screws onto either presta or schraeder valves. Ive used it once and it worked well.

Had to only used it one time so far, it has a advertising of pumping up to 120PSI but could only get 80 from it. Just a typical back pocket pump.

The pump manual comes with the following instruction

On presta valves with a removable valve core: Before use with pump, remove valve core and apply small amount of LOCTITE thread locker to valve core threads. Reinstall valve core and securely tighten.

My experience

To use this pump, you screw on one end of a flexible hose to your tire valve stem and the other end to the pump. After pumping when you remove the hose it rotates the same direction as unscrewing a removable presta valve core. Your valve cores will want to unscrew with the flexible hose instead of staying in the stem. You may need to use pliers to unscrew the core from the hose and it is easy to damage the small rubber seals on the valve core.

Even if you LOCTITE your own valve core stems it could be disastrous to loan this pump on the trail because another rider's valve core stem could get jammed in your hose, which leaves them without a valve core, and renders your hose and pump unusable until you can unscrew their valve stem.

The pump has unscrewed valve cores in several my Kenda and Q-Tubes brand presta tubes, I can't trust taking it out on the trails with my MTB.

I don't know of any problems using this pump with schrader valves but that's not what I bought it for.

I use the pump to inflate tires on the road. I don't normally check pressure after repairing a flat but the pump does seem to be able to achieve high pressure as advertised. I like the small size and efficiency of the pump and I'm completely satisfied except for a couple of minor points 1)the rubber dust cover gets in the way when when inflating the tire and 2)the pump tends to rattle a bit if it's not fastened down snugly.

Great bike pump, light, compact, and very functional.

I really like this pump and wish I had bought it before the others. It's light and extremely easy to use. The hose screws into the pump and doesn't rattle, then unscrews and attaches outside for easy use. It came with a frame bracket which I put on one bike, and I keep it in my jersey pocket when I ride the other.

I've had other pumps snap my valve stem because they connect right onto it and they heat the stem up when trying to get to 100psi. I've had to use this pump several times and it works well, though as other reviewers mention, it does take some physical effort to get your tire to a point where you can ride.

I'm a recreational rider and use my bike for short commutes and for fun. It's nice to have a light, easy-to-use pump to take along for topping up tires or contending with possible flats. I often lock and leave my bike where something like a pump should definitely not be left on the frame. One thing I especially like about the design of this pump is that it is easy to slip from the frame and carry along with me when I've arrived at my destination.

I ride with a Lezyne on both of my road bikes and my timetrial bike. Great tool...

The pump is light, easy to use and pumps up a tire easily. It does take some effort to get the tire up to 100 psi.

Absolutely one of the lightest and functional pumps on the market. Low profile

that fits just above your front deraileur perfectly. Operates just as designed.

What can I say? It gets the job done in a very small and lightweight package. Small enough to easily fit in a back pocket with risk of falling out.

There are two shortcomings. First, the detachable rubber tube can rattle around a bit. This can be noticeable if you use the frame mounting kit. However, I never hear it when I put the pump in a rear jersey pocket.

Second, you have to be careful when using this kind of pump (i.e. one that screws onto inner tubes) with tubes that have removable valve cores. I found myself in a jam out in the middle of nowhere when the pump kept removing the valve core when I was done pumping the tire up. Now i carry a little tool that allows me to really tighten the valve core down before using the pump.

Fits in my handlebar bag. Used it once so far, to reinflate a slow leak on a 30 mm tire. Worked well and got me home.

This pump work fine. Unfortunately the velcro piece is so short it will not got around frame of bike. Really? for a 40 dollar hand pump could they have spent another 10 cents and given us more than a 4inch piece of velcro? Did they test the attachment with any road bike to see what would happen? I actually took it to a bike shop to see if I was missing something, but no they could not figure it out either. They ended up selling me a bigger piece of velcro. Ridiculous.

Compact and light, but it rattles.

Ive been able to repair my tires and use this pump to fill back yo 100psi

This is great little light weight pump that is able Pump to road bike tire pressure .

The Lyzene Hand Pump is solid and user friendly and is small enough to put in a medium seat bag. It takes up about the same space as 2 CO2's. The flexable tube and quality are what sets this pump apart.

wish it had presure gauge

These pumps are small, light and very well-made. Look nice, too. I like the bottle cage mount, too.
