My new Mojo has five hearty rides so far with no issues until now. The Pro Pedal lever will not stay set to "on", it just springs back to off. The damping circuit works as it should, the control lever just won't stay put. This started just after I adjusted the Pro Pedal setting. What should I do? Have other's had a similar problem? Is there an easy fix or does the thing need to go back to the shop?
