The perfect all-round adventure gravel bike featuring the award winning Fazua evation drive system

The E-Substance is built around a truly versatile aluminium frame, with integrated electric drive system from Fazua - the lightest and most compact drive system in the industry. Based on the award winning Substance, with the addition of a mid-position motor results in a bike that handles every bit as well as a traditional adventure gravel bike, but with the added benefit of a little assistance.

Fazua evation is the most compact drive system around, thanks to it's slim integrated design, meaning the E-Substance retains a classic look. A unique natural riding feel with no mechanical resistance above the legal speed limit makes the E-Substance perfect for anyone looking to enjoy a fun ride at any speed, on any terrain. 3 levels of assistance up to 250 watts allow you to tailor the ride to suit. Featuring the latest generation evation with integrated Top Tube controller.

The frame features internal cable routing, and is paired to a full carbon fork with tapered steerer. Both frame and fork include mounts for mudguards, with the frame featuring rack mounts. Alongside the drive system is a SRAM Apex 1x11 speed hydraulic disc groupset with FSA chainset, with 'go-anywhere' gearing. WTB Venture TCS tubeless tyres come fitted to a gravel specific set of Prime Kanza 650b wheels
