A road bike that looks like the same thing, a road bike, and yet hides inside an electric assistance system that provides up to 40 Nm of torque through three assistance modes accessible by pressing a simple button integrated into the frame. This is the Ribble Endurance SLe, an e-Bike for asphalt with a carbon frame and a weight of 11 kg in its lightest set-up.
The Ribble Endurance SLe is an electric road bike with a monocoque frame made of Toray T1000 and T800 carbon fibers. The chassis, in addition to holding a completely hidden 250W battery inside, is designed to reduce the vibrations of the asphalt thanks to the studied shapes of its tubes, just as in the case of high-performance road bikes from many manufacturers.
The most striking aspect of the Ribble Endurance SLe is that it has an engine integrated into the rear hub, totally unnoticed, achieving an aesthetic very similar to a conventional bicycle. It is the same system used in the Orbea Gain-Road (another road bike with electric assistance), consisting of a motor coupled to the wheel axle instead of the bottom bracket to eliminate any kind of resistance when not working, a battery perfectly integrated in the frame and a control unit also integrated in the upper tube.
The Ribble Cycles Endurance SLe is available in five sizes (XS, S, M, L and XL) and four road-oriented configurations, all with hydraulic disc brakes and components that can be customized by the user at the time of purchase. The range comprises Endurance SLe with Shimano 105 group (€3,365), Shimano Ultegra group (€3,814), Shimano Ultegra Di2 group (€4,487) and SRAM Red eTap group (€5,834).
