How is the FlexLink/FlexLink Pro suspension different from the original 2017 M-Series?

Since the original M-Series release, we’ve improved upon our mid-wheel drive stability with an optimized linear spring design to enable even greater freedom of movement and more power driving positions. FlexLink and FlexLink Pro suspension is factory optimized for user weight range, while still allowing field adjustability to accommodate user environment, preferences, and changes over time.
