Bike Yellow Telescope Mini Pump, Compact and Portable, Fits Presta, Schrader and Dunlop Air Valves - AI-AP-87Y

It's tiny and portable like a mini pump should be. It does have some flaws. The design is sleek, but there is no good handle for either hand. The hand holding the top will be in danger of slipping or getting pinched between the top and bottom portion while you pump. The top portion is less than half the width of my fairly small hands. The bottom portion is longer, but it is also smooth with no good grip that gives you the leverage (not the right term but you get the idea) to push it in especially when your tires are at a higher pressure (even struggles to push it in easily at 60psi). Finally, the hose idea at the end is a good idea but still too short to avoid wiggling the stem since you have to work so hard to pump it since it has no good handholds. It's also a very slow pump. Slower than the others I have owned previously. Clearly it's a mini pump meant for emergency flats on a trip, but plan on pumping for 30 minutes to get a road bike tire to half pressure.

Well built, compact and works perfectly. This is a great little pump.

The idea was good, and it looks very very cool, but unfortunately it doesn't work. It does not work with shrader valves, and with the presta, although it fits easy, every time you pump air the head moves slightly which causes the presta valve to lose air again.Don't buy, waste of money

Good pressure and reinforced structure . A good pump for MTB

The adapter for the presta valve is not as good as it could be.

Fancy yellow bike pump that bolts to your water bottle holder. Find another place to put your water bottle, and be able to inflate your flat tire out in the middle of no where. Build quality is nice, very light.

Doesn't work. Gave as a gift to a friend last year, they finally had a low tire and were unable to use it.

Light, compact, sustainable and efficient
