Pump

When it comes to portable bicycle tire-inflating devices, hand pumps require a lot of effort, while CO2 cartridges are single-use only. That's where the aluminum Choka bike frame comes in, as it doubles as a compressed air tank.

Invented by siblings Joe and Christine Edell, the AirLock is both a tire pump and a cable lock.

Portable, cordless air-compressors aren't new, but they're often bulky, limited in scope and ugly. In response to these issues, a team of engineers and product designers fro Hong Kong has come up with the Norshire Mini. A compact, minimalist, multi-function pump/compressor for the iPhone generation.

​While people are fairly fussy about things like bicycle tire pressure, they tend to be a lot more blasé when it comes to inflating basketballs – even though a ball's pressure can greatly affect its performance. The Innoflate Perfect Pressure Needle is designed to help … by whistling.

​Founded in Italy in 1917, Silca was the first company to put an air gauge on a bicycle tire pump. Now based out of Indianapolis, the manufacturer has sort of come full circle with its Viaggio Bluetooth-equipped floor pump – it's taken the gauge back off, and put it on the user's smartphone.

​For nursing mothers who don't wish to be tied down to a non-portable breast pump, there are already wearable versions that can be slipped under a bra. Women's tech company Elvie is taking things a step further, by announcing what it claims is the world's first silent wearable breast pump.

​Serious cyclists typically carry compact hand pumps with them on long rides. Using such a pump to inflate a completely flat tire from scratch, however, can be an arduous process. That's why the foot-operated Stompump was created.

When a cyclist has to change a high-pressure tire at the side of the road, pumping it back up using a compact hand pump can be quite the hassle. An alternative was unveiled at Interbike this week, however – the pocketable miniFumpa battery electric pump.

Thanks to gravity, fluids flow downwards following the path of least resistance. Now researchers at Brandeis University have mixed biological molecules into a substance that marks the first steps towards developing a self-propelling liquid, that could flow free of human or gravitational influence.

Most breast pumps require secluded privacy to use, oftentimes leashing women to wall outlets and/or bulky tote bags. The Willow wearable breast pump, showcased at CES 2017​, promises freedom with a wireless ​hands-free design that slips right under one's clothing.

​Instead of bothering with a hand pump for refilling flat tires, many cyclists instead just use a compressed air cartridge. That said, they still need a set of tire levers. With that in mind, Bar Fly has created a lever that doubles as a CO2 inflator.

​Although you certainly can inflate a bike's tires using a hand pump, doing so typically involves some time and effort. Production Functional Factory is attempting to address that situation with Bimp Air, a refillable compressed air system that's charged by the spinning of the bike's front wheel. ​
