CYCPLUS Tiny Electric Bike Pump AS2Pro — Black, 120g Aluminum Alloy, 120 PSI & LED Auto Stop

The CYCPLUS Tiny Electric Bike Pump AS2Pro is a pocket-sized, 120g cordless inflator that quickly fills bicycle tires up to 120 PSI with an auto shut-off LED gauge for accurate, hands-free inflation.

Compact enough to carry on every ride, the AS2Pro blends lightweight engineering with enough power to service road, mountain, city, and e-bike tires. Its aluminum-alloy shell keeps the unit durable while weighing only 120 g (4.23 oz), and the built-in LED display and automatic stop let you set a target pressure and walk away. With fast 30-minute charging and compatibility with both Presta and Schrader valves, this little pump reduces roadside downtime and fits neatly into a pocket, saddlebag, or backpack.

How fast will the AS2Pro get my tire back on the road?

The AS2Pro is optimized for speed and efficiency: it reaches up to 120 PSI and refills a 700x25C road tire from 0–80 PSI in about 52 seconds. A full charge can inflate at least two 700x25C tires from 0–110 PSI, making it practical for quick ride recoveries.

• Maximum pressure: 120 PSI for high-pressure road and e-bike needs.
• 700x25C tire: ~52 seconds to 0–80 PSI.
• Road tire series: ~120 seconds to 0–120 PSI for heavier inflation.
• Battery endurance: two full 700x25C inflations on a single charge.

Will it work with my bike’s valve and fit in my pack?

This mini pump supports both Presta and Schrader valves through a 2-in-1 head and includes an extra air hose to reach awkward valve angles. Its pocket-friendly dimensions make it simple to carry whether mounted to a backpack, tucked in a jersey pocket, or stored in a saddle bag.

• Valve compatibility: built-in Presta and Schrader support.
• Accessory: flexible air hose for tight or angled valves.
• Size: 2.75 x 1.10 x 1.92 inches — fits most storage spaces.
• Weight: 120 g (4.23 oz) for minimal carry burden.

How do I use the pump and read pressure accurately?

Attach the head to the valve (or use the included hose), set the target PSI on the large LED screen, and press start. The AS2Pro measures pressure with ±1 PSI accuracy and will stop automatically when the preset pressure is reached, so you avoid over-inflation.

• LED display shows real-time pressure and set target.
• Auto shut-off when target PSI is hit for hands-free use.
• Measurement accuracy: approximately ±1 PSI for reliable readings.
• Simple controls: set, start, and disconnect when finished.

What about charging and overall reliability?

Fast-charge capability brings the AS2Pro to full capacity in roughly 30 minutes. The robust aluminum-alloy casing offers impact resistance for everyday riding, and the compact design minimizes moving parts, improving durability on trail or commute.

• Charging time: ~30 minutes to full battery.
• Durable materials: aluminum alloy shell for lightweight toughness.
• Ready for multiple inflations per charge for longer outings.
• Minimal maintenance—keep valves clean and charge periodically.

Who is this for: The CYCPLUS AS2Pro is designed for cyclists who want a dependable, ultra-portable inflator that fits in a pocket but performs like a full-sized pump. It suits road cyclists, commuters, mountain bikers, and e-bike riders who prioritize quick roadside repairs, accurate pressure control, and low carry weight. If you need a compact emergency inflator that delivers fast, precise fills and supports both Presta and Schrader valves, the AS2Pro is a practical choice.
