Quality and Versatility: We don't like wimpy components. Our dovetail seat rail and mating mount are examples of our attitude toward proper design. No light duty parts which could slip and cause an accident. A lot more work on our parts, like the nice little corner radii on our machined parts, but the Longbikes philosophy dictates that extra effort!
Standard drive train (below on the red bike) uses conventional tandem cranks with the timing chain on the left. Independent pedaling (shown above on the green bike) moves the drive train completely to the right side and moves the steering to the left.
