The Main9 Superharness is far more than a breakout cable: it features an integrated PCBA that overcomes many limitations of the stock ASI controllers and adds unique regen braking functionality previously available only with a Cycle Analyst — including support for bidirectional throttles, digital ebrake with throttle modulation, and proportional analog regen ebrake levers.

Specs:

• 5-pin Female HiGo: connects to ebike displays using the KM5s protocol
• 4-pin Female HiGo: ebrake plug (5V, Gnd, Digital, Analog); supports 1-4V proportional brake levers or throttles as a regen source, plus digital brake cutoffs
• 3-pin Female HiGo: throttle plug; conventional 1-4V hall throttles and bidirectional throttles with a 0-1V regen range
• 5.5x2.1mm DC front light: up to 2A, controlled from the display
• 5.5x2.1mm DC rear light: blinks normally, steady while braking
