We're now making a 3-speed handlebar switch preconfigured for the V3 Cycle Analyst with internal resistors to switch between 1.6, 2.5, and 3.3V. This plugs into the Auxiliary input of the CA, and can be configured for low, medium, and high power modes, or it can be set up to automatically change between any preconfigured mode presets. It's a super handy way to quickly customize your ebike's behavior.
