| Sixfinity is a 6-bar linkage suspension platform that allows kinematics and chassis structure to be tuned for the specific demands, and packaging constraints of an E bike. At its core, Sixfinity exhibits many underlying behaviors of Switch Infinity, but with intentional variations to account for the fundamental dynamic differences that come with the addition of a drive unit and battery. Like Switch Infinity, Sixfinity’s lower Switch link first moves upward, and then switches directions and travels downward as the suspension moves from the extended to compressed states. As a result, Sixfinity has a similar anti-squat profile proven with Switch Infinity. However, due to the drive unit assist, the magnitude of the profile is reduced to bias the acceleration response towards increased traction. The Sixfinity anti-rise profile is consistent across the entire travel range, similar to Switch Infinity. However, the magnitude is reduced to bias the deceleration response towards increased traction for a composed and predictable performance and chassis geometry while braking, even with the added mass of a drive unit and battery. Sixfinity's leverage rate curve is linear and progressive. However, the progressivity is both increased and adjustable to be tailored to one’s specific riding style, trail conditions or shock preference. |
