Rose Bikes Backroad+ GRX RX810 Di2



The BACKROAD + GRX RX810 Di2 delivers high-end gravel performance. The modern frame design of this ROSE e-bike platform integrates the battery, motor and cables. Power from the first step, in the city, in the country and in the mountains – the BACKROAD + has everything you would expect from a modern high-end gravel bike of the next generation.

This e-gravel bike is equipped with high-quality Ritchey WCS Venture Max carbon dropbar handlebars and a clean ROSE Square stem as well as high-end Shimano SC-EM800 color display – you get full control and easy handling in any terrain through intuitive control of the three support modes of the Shimano EP8 via the STI switches of the Shimano GRX RX810 Di2.

9.2Expert Score
Top-flight gravel e-bike with Di2 from Rose Bikes
The Rose Bikes Backroad+ GRX RX810 Di2 is the lightest e-bike (that I'm aware of) that uses the Shimano EP8 motor. Weighing in at a claimed 14.3kg it's an absolute featherweight when you compare it to similar mid-drive e-bikes. Fazua-powered gravel e-bikes generally weigh around the 15kg mark, but that motor only produces 60Nm of torque. This bike must be an absolute blast to ride with 85Nm of torque available from the EP8 motor. To top it all of the Backroad+ has Shimano GRX Di2 with the left shifter also controlling the e-assist. This looks like a cracking electric gravel bike and it's a shame Rose Bikes no longer ship to the UK, as I'd love to get my hands on one for a full review.
  • Shimano EP8 motor
  • 360Wh battery
  • Shimano GRX Di2
  • Lightest Shimano EP8 e-bike (that I'm aware of)
  • Not currently available for UK shipping
