Lezyne HV Drive High Volume Hand Pump, Medium: Silver

I have not had the chance to use the pump (medium version) to fix a flat in the field but I did test it in my garage. The schrader and presta connections seem solid. Of course such a small device is going to require LOTS of pumping to fill a tire depending on 1) the tire volume and 2) the final pressure you desire. I have 406 (20") and 559 (26") tires on my trike and I will accept the occasional workout given its small size weight and solid connection to my tubes. Time will tell if I am correct in my assessment.

This pump appears to be the earlier version of the "Drive HV" series. The newer is the "Grip Drive HV" which has knurling on the handle. This model is cheaper and I would think works just as well.;

Sure you can buy the grip drive HV and get cool knurling and more aluminum but this one is exactly the same size and seems to have the same capability.;

I bought this to use as an air pump for a squirt gun. It pumps strong and with a little tweaking on the hose it worked perfectly for the air supply.;

Die Pumpe macht einen soliden Eindruck. Mit dem Schlauch lässt sie sich einfach mit dem Ventil verbinden. Je nach dem wie man den Schlauch einschraubt kann man verschieden Ventiltypen bedienen.
Die Halterung mit dem Klettband ist stabil. Leider passt sie nicht an EMTB die den Akku im Unterrohr habe weil die beiden Anschraubpunkte zu kurz sind für ein breites Unterrohr. Hierfür ein Stern Abzug.;

Compact and light weight. Easy to use and connect onto ebike.;
