If you're looking for a lightweight and low profile mountain bike mini-pump with functional good looks, then the Birzman Velocity Apogee MTB is an excellent pick. It delivers impressive pumping performance for its small size and has the added benefit of doubling as a front shock pump in a pinch, a unique feature in the mini-pump segment.
For those in search of top-notch performance, check out the Lezyne Gauge Drive HV, our Editor's Choice. It's a similar looking mini-pump that offers more volume. It's a few inches longer and a little bit heavier.
