Colnago E64 Ultegra Disc Electric Road Bike
Italian brand Colnago have released their first e-bike, the E64 Ultegra Disc Electric Road Bike, so you can retain the traditional style and top performance, with a little extra help for faster climbing and longer, easier riding. The 250-watt motor is discreetly hidden inside the rear hub, and the battery inside the down tube so you have to look fairly closely to spot the difference from a non-assisted model. The system weight is kept to a minimum at around just 3.7kg so at around 12 - 13kg for the build, this is one of the lightest e-bikes out there.
It's not all about the extra power, though, this bike boasts a stiff carbon monocoque frame and fork and has been built up with a full Shimano Ultegra groupset for smooth shifting and powerful hydraulic disc braking. Rolling on Mavic's Aksium Elite Evo tubeless ready wheels and wide Continental Ultra Sport II 28c tyres, you can be sure of a comfortable, responsive ride and reliable performance.
Features
- Light and stiff monocoque carbon fibre frame and fork
- Ebikemotion motor can deliver up to 250 watts of assistance
- An additional external auxiliary battery can be added to boost range
- Shimano Ultegra groupset
- Mavic Aksium Elite Evo tubeless ready wheelset
Please note: This is the Shimano Ultegra mechanical specced bike. Images are representative of colourway only. Please see images for sizing.
