Trek launch their first e-road bike, the Domane+

Trek have ventured into e-road with an electrified version of their popular Domane endurance bike, the Domane+. They say its Bosch drive system "sustains Tour de France speeds at cycling-around-the-block efforts."  

Stealthy assisted speed: e-bikes that look like road bikes

The Domane+ is equipped with a 500 Wh battery and a Bosch Performance Speed motor, and Trek say it can go up to 100km on a single charge. The one-piece Removable Integrated Battery system is fully concealed within the frame, and can be removed or installed without any tools. Trek also make an odd statement about group rides being unable to 'hold the wheel' when the bike gets up to the rip-roaring 25kph that you're limited to in the UK... we'll assume they're referring to going uphill.

Sram's 1x11 Force 1 drivetrain provides shifting duties, and you also get Sram Force hydraulic disc brakes. The frame has full internal cable routing, hidden mudguard mounts and there's also a built-in kickstand. The wheels are Bontrager's Paradigm Disc Tubeless Ready dressed with Schwalbe G-One Allround 35mm tyres. 

The Bosch battery also has another advantage, in that it powers the built-in Supernova integrated light system. Trek have kept many features of the non-assisted Domane, such as the IsoSpeed decoupler at the rear that's designed to absorb road buzz, thus improving comfort. The whole bike weighs in at a claimed 17.19kg, and costs £5,000 (there are no other specs listed as of yet). You can buy it directly from Trek or from numerous dealers countrywide.
