Trek has released the Domane+ SLR, its first true performance e-road bike.
The Wisconsin-based brand says it delivers “an unprecedented speed to weight ratio”, with the top-tier model weighing 11.8kg/26lb and providing a maximum assist of 28mph in the US and 15.5mph/25km/h in Europe.
If the holy grail for the best electric road bikes (opens in new tab), or at least the path to greater acceptance, is to appear largely indistinguishable from regular road bikes, then Trek has seemingly made up serious ground with the Domane+ SLR.

First impressions are that it looks a lot like, well, the new Domane SLR (opens in new tab), released just last month. Taking a cursory glance perhaps the only give away is a beefier downtube – where the 360Wh battery is stored – and even then it has the appearance of a tube shaped for aerodynamic advantage rather than one made bigger so it can hide a battery.
If it closely resembles the latest Domane, that’s because it shares many of its attributes. Trek deemed the Domane “the perfect chassis” for a performance e-road bike thanks to its versatility and “rider-friendly” features. The Domane+ SLR is made using Trek’s premium 8000 Series OCLV carbon, as is the regular SLR, which contributes to the bike’s impressively low weight; even in its heaviest configuration (based on 56cm frame size) the Domane only weighs 12.6kg or just a shade under 28lb.
It features Trek’s endurance geometry, which means a taller head tube and a longer wheelbase, just like on the regular Domane. The updated rear IsoSpeed technology, here to help reduce road chatter and make for a smoother ride over longer distances, remains as does the RCS integrated stem system. Likewise, the electric Domane has mudguard mounts, making it winter-ready and commuter-friendly.

Making the Domane+ SLR feel like a regular road bike is another part of the puzzle, which if solved will likely lead to yet more converts. Alongside the frame material and design attributes ‘borrowed’ from the ‘acoustic’ Domane, Trek have also managed to equip the electric version with what it describes as a “close to standard Q factor” – the distance between the pedals attachment points on the crank arms. It measures 163mm and is possible to the compact nature of the Domane+ SLR’s chosen motor.
And it’s this motor which is likely to garner much attention and draw many plaudits. While there are plenty of roadies who will…
