The new Giyo GP84ST telescopic high volume mini bike pump adds to our 2025 lineup of compact bike pumps with excellent functionality. Small enough to fit inside the bike frame, but with a telescopic CNC machined aluminum alloy barrel that gives you high volume when you need it. That’s not all, because concealed in the barrel is a pull-out-and-swivel hose with dual function flip twin valve for Schrader and Presta compatibility.
For our new 2025 design, the GP84ST builds on our established experience of building high quality mini bike pumps, and brings together some of the most popular features of existing designs with the addition of a telescopic barrel for higher volume. By packing a host of customer favorites into a high quality, small footprint design we’ve created a mini bike pump that ticks all the boxes for the biking community.
The new GP84ST builds on the success of our GP84S by adding a telescopic pump for high volume. A perceived issue with micro bike pumps is the low volume that results from the compact design. By making a telescopic micro bike pump we are able to increase the pump volume to 50cc per stroke, reducing pumping time and making it easier to pump up higher pressure bike tires.
The slim, CNC machined telescopic body of the Giyo GP84ST can be fitted inside a bike frame, making it an easy choice to take on a ride. With the unique pull-out hose and high volume design it also gives you the flexibility of a floor pump to fill tires at any angle: upright, lying on the ground, or anywhere in-between when you’re out on the track.
Our telescopic mini bike pump retains the sleek format of our mini bike pump range, which makes it fit easily into most bike frames, as well as coming with an on-frame mounting kit which includes a molded tab to keep the pump closed while clipped to the frame. The extending hose is neatly retained in the tube when not in use but is easily extended when needed.
Simply unscrew the alloy barrel of the twin valve head from the flexible hose, flip it end for end and screw it back on to change between Presta and Schrader valve types. There are no fiddly inserts to lose, just set it for your bike and forget it!
At only 74g, this is a very lightweight pump, but with high capacity and capable of 120psi it challenges the performance of pumps that are twice the size. Add the flexibility of the built-in extension hose and you have a full size, full performance bike pump in a mini-pump package.
The ergonomics of the GP84ST are exceptional, with a soft comfort grip and CNC machined texture to the pump head. This combination makes this mini bike pump secure and easy in the hand without slipping or requiring additional force to keep it stable in use.
