Our bike bump works through the operation of air pressure with a piston inside a cylinder. When we pulled the lever, the air will save into the cylinder. When the lever is pushed down, the air is expelled in the tire. Mini bike pump has a gauge to note the air pressure within the tire and avoid blowouts happening during the journey. Riders should keep a mini pump attached to the bicycle frame to fill the tire easily while cycling.

• √ High-Pressure Capacity: The portable bike air bump can pump up to 260 PSI and needs less force to pump that's why airing the bike tires super fast, and you can save a lot of energy for cycling.
• √ Durable & Lightweight: Bike pump is made of T6 aircraft grade aluminium making it extremely lightweight （160g） and durable. It can also fit in a small tool case and attached to your bike or in your backpack.
• √ No valve changing needed at all: Both for presta and schrader valves.You can use our portable bike pump for any bike like BMX's, kids bikes, etc. without having to change the valve.
• √ No Leak!!!: The bike pump has completely sealed hose onto the valve thanks to the screws so that's why no leak of air from the pump. That hose can be attached to the bike pump, and you don't need to worry about it.
