In order to perform trailside repairs, mountain and gravel bikers need two things: a multitool and a compact pump. That's where the Daysaver Incredible Pump comes in, as it's a little pump that accommodates a tool (or two!) within its hollow handle.

German manufacturer Schwalbe has revealed what it says will become the industry standard in bicycle tire valve systems. Known as Clik Valve, the setup is claimed to be much easier to use than existing systems, and to boost air flow by up to 50%.

Flextail has made it a mission to design battery-powered pumps tiny enough for even the most ultralight of camping trips. All those efforts have led to the new Zero, a pump so small it clips to a keychain and brings automated inflation everywhere.

Pumping up deflated tires has to be one of the most cumbersome tasks on two wheels. The electronic Mini Pump, pitched as the world’s lightest tire inflator, is just the kind of handy gadget that you’ll want to take along for the ride.

While there are already garments which cool or warm their wearer via circulating liquids, those garments tend to be equipped with cumbersome, noisy pumps. An experimental new system, on the other hand, uses interwoven tubular fibers as pumps.

Researchers have developed an implantable pump that can deliver chemotherapy drugs directly into the brain to fight hard-to-treat cancer. In a phase 1b trial, patients were able to undergo the therapy while going about their day-to-day activities.

How exactly kidney cells transport blood through the organ's tubes has remained a mystery. Now researchers at Johns Hopkins University have investigated the mechanical forces at work and found a previously unobserved pumping action by kidney cells.

Among other items, serious canoeists are advised to carry an extra paddle (in case they lose one) and a bilge pump (in case their boat gets swamped). The Paddle Pump is designed to make things simpler, by combining both tools in one device.

Soft-bodied robots move via pneumatic "muscles" that are selectively inflated or deflated. And while the muscles themselves may be soft and squishy, they're usually hooked up to hard, unwieldy pumps. A new pump, however, is both small and flexible.

When it comes to portable bicycle tire-inflating devices, hand pumps require a lot of effort, while CO2 cartridges are single-use only. The aluminum Choka bike frame offers an alternative, by doubling as a compressed air tank.

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