CrankTank4 is a different and very easy, simple way to carry and access a larger quantity of water on your bike.

Conceived with the more remote traveller in mind, we have come to realise that it is also a great piece of kit to have even when just heading off on a big day out. No more detours to find water.

When designing the Cranktank4, we had these objectives.

  • Enough capacity for 24 hours in mild conditions (or all day when hot) so 4 litres
  • Easy and safe access for drinking while on the move
  • Space efficiency
  • Minimal impact on handling when full, so positioned low and central on the bike
  • Securely mounted but still quick and easy to remove
  • Robust and lightweight
  • Able to fit as many conventional double triangle frames as possible

We reckon we did what we set out to do.
