The only pack you need is the Bike One.

From its integrated rain cover to the super-ventilating back panel and straps, there's no doubt that the Deuter Bike One 20 Backpack is designed for the biking and hiking enthusiast. Even after dropping in a hydration bladder, this pack still leaves you with 20 liters of space so you can bring along some extra clothes, food, and on-trail supplies.

  • Airstripes System features two separate foam back panels that flex separately and allow air to channel upward and out at the neck
  • AirMesh lining on the back panel, contoured shoulder straps, and mesh wings provide maximum breathability
  • Removable foam back panel lets you vary the amount of padding to handle different load sizes and works as a sitting pad
  • Stowaway mesh helmet keeps your biking lid handy
  • Double-sewn, bound seams offer lasting durability and eliminate fraying
  • Hydration pocket compatible with a 3L bladder (bladder not included)
  • Integrated rain cover features a sewn-in reflector for increased visibility

Gold Standard bike pack

  • Familiarity: I've put it through the wringer

I replaced this bag's predecessor only after its colors had faded from 10 years of UV exposure. Like the previous "SuperBike L" this bag has a integrated rain cover and a hydration bag. It also has a helmet carrier which unlike the prior model is in a small zip pocket. The old external helmet straps degraded with UV exposure after 10years... A nice improvement is that the small personal pocket for your keys, snacks, glasses is now on the outside and top of the bag making access easier. The bag is optimal size for both biking and day hikes. The workmanship seems superlative. Really a gold standard product

just too big

  • Gender: Female
  • Familiarity: I returned this product before using it

great features in a well made pack but ultimately I returned this pack and the Deuter Trans Alpine as well...just too big for mountain biking (for me). I wish I could find out about 3/4 that size. Seems like there are a lot of crappy hydration systems on market, would love a Deuter pack in more compact size.I wish packs in general were better organized with its pockets for bike stuff, and larger liquid bladders.
