Review on Compact and Lightweight Mini Bike Pump - Fits Presta and Schrader Valves - 160 PSI - Includes Mount Kit - Ideal Bicycle Tire Pump for Road, Mountain, and BMX Bikes - Only 2.9 oz by Djuan Thompson

The ICOCOPRO mini bike pump is a well built, lightweight pump. It doesn't take up much space (5" long, 3/4" diameter) and shares the mounting holes with the bottle cage. I used this on the trail. I was able to inflate a flat MTB tire. However, it's a real workout to do with this mini pump. I didn't count the number of pumps, but it was a workout. I keep this on my bike as a backup for my CO2 pump and keep 2 pieces of Gorilla Tape for JIC wrapped around it. For that I would say it's a good buy. If you use it as your primary trail pump, I hope you don't have flat feet or don't like training your arms on the trail.
