Pump

​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. ​

​While there are various ways of stowing a compact tire pump within a bicycle, a full-size model is almost always going to make the pumping easier. That's why Alexander Haager created the AirSupply pump, which doubles as a seatpost.​

It was three years ago that we first heard about the PumpTire – it was a prototype bicycle tire that used wheel motion to keep itself inflated. Well, its designer has now come up what sounds like a better alternative: the PumpTube.

When most of us think of a cycling multi-tool, we picture something that goes in a jersey pocket. The Kickstand Pump, however, mounts on the bike and serves not only as a kickstand and pump, but also a tire lever and tail light.

Tubeless mountain bike tires definitely have their good points. In order to seat the things securely on the rim, however, it's often necessary to use a compressor or a CO2 cartridge to deliver a shot of air. That said, there's now another option, in the form of the Airshot.

When it comes to inflating bike tires on the road, there are two options: a compact hand pump, or a CO2 cartridge. DesignAir Innovations, however, has created another one. It's called RideAir, and it's refillable portable compressed air pump.

Dutch startup aQysta, a Delft University of Technology spin-off company, manufactures what's known as the Barsha irrigation pump. It can reportedly boost crop yields in developing nations by up to five times, yet requires no fuel or electricity to operate.

If you own a higher-end bike with a Shimano drivetrain, then chances are it's got a "secret" storage compartment: the hollow space in the axle, that connects the Shimano Hollowtech cranks. While you're not going to be able to fit your wallet in there, you can pop in the new CrankPump CO2 tire pump.

Start with a Vauxhall/Opel/Chevrolet/Saturn Astra VXR, shed 100 kg by replacing metal with carbon fiber, then pump its 2.0-liter turbo engine to 297 hp, upgrade the suspension wheels, tires, gearbox and brakes to cope with the stresses, and you have the Astra VXR Extreme ... and it's street legal.

Need to pump up a ball, bike tire or whatnot, but don't feel like doing a lot of manual pumping? You could take the item up to your local gas station and use its compressor, but Airman is hoping that you'll use its Airgun instead.

Three DARPA-sponsored research teams have developed the world's smallest vacuum pumps.

The BioLogic PostPump 2.0 is a full floor pump integrated right into your bike.
