You can use it to pump your car tires too. I've tried to pump my car tires with a regular floor pump before and it's a pain in the a--. I'm assuming you can use it to pump up inflatable pools. I had to inflate my daughter's inflatable pool the other weekend and I just about passed out (it's really large). If you buy it to use only on your bikes, that's kind of lazy. But it has a lot of other legitimate applications as well.
