Everything that other e-road bikes arent: The Roadmachine 01 AMP ONE is uniquely engineered for high mileage with hidden power. Innovative and researched were continuing the Roadmachines lineage by allying a technically refined design with the exceptionally light and quiet class 3 TQ-HPR50 drive unit. Seamlessly integrated into the Premium Carbon frame everything adds up to make this a favorite for endurance: note the Shimano Ultegra Di2 groupset ICS2 stem and CRD-400 SL wheels. In short its an elevated BMC design amplified to meet the timeless needs of the Roadmachine rider.
