The Red Bike was actually built in less than 5 days, from the Sunday morning to the Thursday evening just before the Tour.
It started with a steel frame that was modified to take the battery holders and mounting points for the controller.
Of course, there was a lot of design work and calculations before the 5 days of assembly. The goal was to create a machine that would have exceptional handling qualities, and be able to blend the power from both man and motor. Neither the conventional wisdom for electric bikes nor the conventional wisdon for road bikes was appropriate.
