Go Ebikes '36V Controller - Fold Sport' $99, sold out; page gives no amps, brand or connectors. Community context: Dragonfly LCD-mount page (round 1) names the stock Fold/Fold X LCD as KT-LCD3, and ebikesforum users say stock SONDORS controllers use proprietary SONDORS-specific plugs ('you will not find controllers with Sondors-compatible plugs anywhere else besides Sondors'); ebikesforum Fold XS thread claims 'Sondors controllers, and display's are protocol protected'. None of this is an official statement.

Electro Bike World product '25amp 36 - 48v KT Controller with HIGO connectors', $88.99, InStock, listed in the 'Sondors Ebike Upgrades' category; page does not name Sondors models, motor-plug pin count, sine/square or display pins. EBW 'KT-LCD8H USB Color Display Sondors' page states it works with this 25 A controller; round-1 EBW KT-LCD3 USB page states it works with 20/25/35 A KT controllers with a 5-pin green HIGO plug. ebikesforum thread 'Need New Controller for Customized Sondors Dirt Machine': 'Electrobikeworld sells KT controllers specifically for Sondors Original fatties... The one you want is the 25a controller'; 'EBW controllers will... have the almost-unique black HIGO connector for the throttle'. ebikesforum thread 'Controller or motor malfunctioning': EBW 25 A controller 'required their proprietary display to complete the circuit' (i.e. display must be replaced together with controller). Voltage 36–48 V range; spec_voltage set to 36 for the bullet-battery bikes.

Same reasoning as Original/Thin; stock Fold display is KT-LCD3 which this controller supports, but no explicit fit statement.
