Cairn E-Adventure 650B review

Oct 2021 · Guy Kesteven

Cairn has rebooted its Fazua-powered E-Adventure bike to make it more user-friendly and added a carbon-wheel-fatter-tire option. Guy Kesteven has been finding out how all that adds up.

Highs
  • Boisterously playful character

  • 650b tires add to the fun

  • Precise and balanced handling

  • Carbon wheel upgrade boosts responsiveness

  • Great price for the package

  • Fazua motor is smooth, silent but usefully powerful

  • Tons of tire space

  • Discreet top tube motor switch/indicator

  • Neater cable routing including dropper post

  • Optional ‘motor out’ storage

Lows
  • Needs low tire pressures for comfort

  • Motor rattle when freewheeling

  • Limited on bike motor/battery info

  • Less range and power than a full-fat e-bike

  • Mixed transmission is noisy when dirty

Cairn E-Adventure 1.0 electric gravel bike review

Aug 2020 · Nick Odantzis

Cairn has taken the already somewhat niche electric gravel bike concept, sprinkled a little adventure dust on it and come up with one of the most versatile e-bikes around

Highs
  • Good for longer rides thanks to additional batteries

  • Removable battery and drive pack allow you to ride with less weight

  • Comfortable cockpit

  • Lots of mounts for adding bags

  • Good tyre clearance

  • Good value - less than £3k isn't a huge amount considering the spec

Lows
  • Relatively heavy with or without battery

  • Quite a firm ride

  • Looks might not be to everyone's taste

  • Battery charging has to be done off the bike

  • Not many bottle cage mounts
