Keep the pressure up (in your bike tires, that is) with a unique device that doesn't take up any valuable space on your frame.
Cue the Air Supply soundtrack: "I'm all out of air, and I'm so lost without it..."
For the recreational cyclist, especially those who don't carry a tire pump with them, dealing with a flat or low tire while out on the road can be a real challenge, but this new pump design could be a potentially effective solution. The AIRSUPPLY, from re.mo.bic, is the result of a seven-year journey to develop a convenient and efficient device for keeping bike tires aired up, no matter if you're at home or out spinning.
The AIRSUPPLY replaces your bike's seat post, and includes not just the pump, but also an inline air pressure gauge and a pouch for holding the air hose, along with an LED taillight. A twist lock on the device keeps it out of the action until needed, and then quickly allows riders to unlock the pump and unfurl the air hose (which can reach both tires without removing it from the bike), after which they can inflate their tires by pumping the seat (which is connected to the top of the pump) up and down. The device adds about a pound to the weight of the bike (480g / 16.9oz), but is said to be capable of producing pressures up to 116 PSI, which is plenty for most casual cyclists.
Here's the video intro:
According to the Kickstarter campaign page, the development of the AIRSUPPLY came about because Alexander Haager, then 15-years old, was frustrated about the current options for bike pumps.
"Alexander envisioned a bicycle with an air pump integrated within, and, despite having no money, technical training or specialized knowledge, quit school to devote his life to the development of AIRSUPPLY™, an integrated pump to fit every bicycle and saddle. In 2013, after conducting experiments and tests with fifteen successive versions of the product and nearly 300 prototype models, AIRSUPPLY™ was finally ready. The product was tested and approved under the European Union’s EN-M standard, the world’s most stringent standard for bicycle parts."
If this sounds like a great fit for your bike, get more info at the re.mo.bic website, or if you're ready to pony up some cash, a pledge of $50 will net you an AIRSUPPLY. The only caveat is that the crowdfunding goal for this campaign is set at $70,000, of which only about $4,200 has been pledged with a little less than two weeks to go, so it's possible that this device may not make it to market as soon as the company thinks.
As an interesting side note on the AIRSUPPLY pump, the project director for it is none other than Michael Lang, who is credited with creating the Woodstock Music and Arts Fair in 1969 (yes, that Woodstock), and the device has received compliments from Wim Ouboter, who invented the original Razor Scooter.
