Ribble claims its new e-road bike is the lightest on the market

The Endurance SLe is an e-bike that doesn't look like an e-bike

The Ribble Endurance SLe is an e-road bike that doesn't look like many of its chunky predecessors, and with a claimed weight of 11kg / 24.2lb it is, claims Ribble, the world's lightest e-road bike — based, we assume, on the top-end SRAM eTap model.

With the tag line 'make it possible', it's clearly designed with accessibility in mind. Ribble says it "makes previously unimaginable mountain passes" possible, and that "not keeping up on hilly group rides" will become a thing of the past.

Ribble Endurance SLe frame

The Endurance SLe is based on Ribble's non-electric Endurance SL road bike, another of its new crop of 2019 bikes.

The SL has a lightweight carbon frame and is designed for endurance riding and racing with an aero fork blade profile, aerofoil seat tube and seatpost, with comfort-giving compliance built in and power-transferring stiffness where it's required.

The SLe frame is understandably a little different, but is still designed to produce comfort and stability.

To provide the strength to support the power transfer and motor needed on the SLe, as well as battery weight (while still looking like it doesn't actually have either), Ribble has opted for a carbon layup with an monocoque mould plus EPS inner core.

According to Ribble this ensures the structural integrity of the frame and minimises excess material on the frame's internal spaces — and, consequently, excess weight.

Power up

The electric motor system provides up to 40Nm of power with three settings, controlled directly from the handlebars rather than any additional handlebar attachment or control. All of the cables are routed internally.

The bike comes with a 250w battery, which can be upgraded to 750w, and drives a rear hub motor that looks similar to the hub-based motor we've seen on Orbea's Gain. The battery can be charged externally and has a claimed 3.5-hour charging time.
