Colnago E64 Ultegra Di2 Disc Electric Road Bike
Inspired by Colnago's C64 premium race bike, the Italian brand brings e-bike technology to their line-up with the E64 Ultegra Di2 Disc Electric Road Bike. There's no mistaking the traditional Colnago style and quality, and at a glance you'd be hard pushed to tell the difference from a non-assisted bike. This is down to the hub-based motor and downtube battery that not only keep things discreet but also make this one of the lightest e-bikes currently available. A button moulded into the top tube is used to control the 250-watt motor, turning it on and off and adjusting the power level. The Ebikemotion system can also be app controlled and linked to your heart rate for enhanced control over the motor's functioning.
With the motor and battery coming in at around 3.7kg, together with the monocoque carbon fibre frame and fork weight is kept to a minimum. The frameset has been built up with Shimano's Ultegra Di2 groupset for smooth, reliable and fast shifting performance. Hydraulic disc brakes provide powerful stopping in all weather conditions. The Mavic Aksium Elite Evo UST EBM wheelset is strong, durable and can be set up tubeless for faster rolling and reduced punctures.
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 Di2 groupset
- Mavic Aksium Elite Evo tubeless ready wheelset
