CENTURION Backfire Fit E R811i DualBatt EQ in Review

Sep 2020 · Jonas Müssig

The CENTURION Backfire Fit E R811i DualBatt EQ has a complicated name and isn't the best looking bike on test either. It makes up for it in other ways. Read on to find out how the € 4,499 trekking ebike with its 1125 Wh battery capacity and a powerful Bosch Performance Line CX motor fares against the competition.

Highs
  • Good-natured and intuitive handling

  • 1125 Wh battery capacity

  • Good handling with luggage

  • Price

Lows
  • Underpowered brakes

  • Lack of comfort at the rear

  • Lack of attention to detail

Feb 2019 · Benjamin Suhr

Yes you're right, the CENTURION Backfire Carbon 4000 is a hardtail MTB. And yet it has more in common with modern gravel bikes than you might think.
