The Independent Coasting Advantage
da Vinci Designs’ Independent Coasting System (ICS) offers you a riding experience both on and off road that equals or surpasses the best you’ve had on a single or tandem bike. The ICS makes for a far more intuitive, comfortable and efficient ride. This newfound ability to independently or collectively coast, pedal and position your cranks at will offers these advantages:
Starting, stopping and going through corners are as easy as on a single bike.
Captain and stoker can independently relax, take a drink, adjust seat position, stand for a few seconds to relieve weary sit bones, even take a moment to gaze at scenery, while the other keeps pedaling.
Traversing obstacles is easier and more efficient because the captain and stoker can coordinate avoiding the obstacles while maintaining forward momentum.
Asynchronous pedaling decreases strain on the final drive train.
