CYCPLUS AS2Ultra Electric Bike Pump — Ultra-Light 90g Magnesium Alloy, 120 PSI, LED Auto Shut-Off

The CYCPLUS AS2Ultra is an ultra-light, pocket-sized electric bike pump that delivers fast, accurate inflation up to 120 PSI with an auto shut-off and a durable magnesium-alloy shell.

Designed for cyclists who want a reliable, compact inflator without adding bulk, the AS2Ultra balances low weight and high performance. At just 90 grams and roughly the size of a small flashlight, it slips into a jersey pocket, backpack, or saddle bag. Despite its tiny footprint, it provides road-bike pressure ranges, supports both Presta and Schrader valves, and displays pressure on a clear LED screen so you can preset and forget while it fills.

How quickly will this pump inflate my bike tire?

The AS2Ultra achieves impressive fill speeds for its size: it can take a 700x25c tire from 0 to 80 PSI in about 52 seconds, and reach 0–120 PSI for high-pressure road tires in around 120 seconds. Expect slightly longer times on larger volume tires like fat-bike or some e-bike casings.

• 700x25c: ~52 seconds to 0–80 PSI
• Road tire 0–120 PSI: ~120 seconds
• Max pressure: 120 PSI (suitable for road, city, mountain, and many e-bikes)

Will the pump fit my valves and riding setup?

The AS2Ultra ships with a 2-in-1 valve head compatible with Presta and Schrader valves and includes an extra flexible hose to reach awkward valve locations. Its small size makes single-handed operation possible and the hose prevents stress on valve stems or rim-mounted pumps.

• 2-in-1 valve head: Presta and Schrader compatible
• Extra hose included to avoid tight angles
• Single-handed use thanks to compact, ergonomic body

How accurate and convenient is the pressure control?

A bright LED display shows real-time pressure and allows you to set a target; the AS2Ultra will stop automatically when that pressure is reached with ±1 PSI accuracy. This prevents overinflation and removes the need to watch the gauge during inflation.

• LED screen with live pressure readout
• Auto shut-off when preset pressure is reached
• Measurement accuracy: ±1 PSI

How long does the battery last and how fast does it recharge?

The AS2Ultra charges rapidly — a full charge takes about 25 minutes — and provides enough power to inflate at least two 700x25c tires from 0 to 110 PSI per full charge. Fast recharge time means it’s easy to top up between rides or during a weekend outing.

• Full charge: ~25 minutes
• Per-charge capacity: at least two 700x25c tires to 110 PSI
• Lightweight battery optimized for quick, short bursts of high pressure

Who this is for: The CYCPLUS AS2Ultra is ideal for cyclists who value minimal weight and maximum portability without sacrificing pressure capability — road riders, commuting cyclists, and mountain bikers who need quick mid-ride inflation. It’s also a strong option for e-bike owners who require higher pressures in a compact tool. If you want a pump that stashes easily, charges fast, and gives an accurate automatic stop, the AS2Ultra is built for you.
