The Bontrager Flash Charger is an unique pump: this pump combines the convenience of a compressor and the handling of an ordinary floor pump. For those who try to get their tyre 'Tubeless', this pump is a godsend.

Of course you can use a 'normal' bicycle pump, but the biggest difference is in the air reservoir, which you bring up to pressure, before inflating the tyre. After about 45 pump strokes your air chamber is fully up to pressure, and the air flows rapidly into your tyre when you push the lever down. This allows the tyre bead to be pushed into the sides of the rim, which creates an airtight connection. Thus, even a stiff, wide or narrow tyre placing is childsplay.

This fantastic pump / compressor belongs in the equipment of every avid tinkerer.

Does what it says

Ideal for seating tubeless tires, good construction and so easy to use. Any reviews that say it doesn't work will have been doing something wrong.

Premium pump for regular use and tubeless initial fill up

I wanted to buy similar pump from Topeak but the price was much higher. I found the cheaper pump from Bontrager and decided to give it a try. The pumping works like a dream as you can feel that the components are well designed and manufactured with great quality and fitting tolerance. Though the filling rate is not as fast as my conventional pumps, it allows me to accurately get the pressure that i need accurately. In case you overfill it, a bleed valve allows you to release the air slowly until the pressure is right. For initial filling of my Schwalbe Pro One, the red lever was easy to use and the air from the presurized chamber was immidiately released to settle the tire to the rim. Very easy to use and i managed to assemble 2 tubeless tires quickly to my Dt swiss RR21 wheels without taking too much time. Right after the tires settled to the rim, using the pump for regular refill is also addictive and fun. looks like christmas came early for me and i highly recommend others to buy it.


  • Very easy to use
  • The connector can be used for both types of valves
  • Connector fit well to the valve without leaking
  • Good desigb, quality and part tolerance
  • Value for money

Not as good as expected

Might work better with Bontrager TLR wheels and tyres. Total failure with Zipp Corsa 30 wheels and Schwalbe 1 Pro tyres. Has to resort to CO2 canisters.
