To control the power mode on the STEPS drive unit, use this Firebolt left hand shifter like the XT/XTR Di 2 version. This shifter feels the same as the Di 2 version for a consistent & familiar feel. Should you get to a part of the trail where riding is not possible, you can active walk mode but pressing & holding the shifter down for assist up to 6kph. Easy to reach without having to move your hand from the grip with adjustable paddles.
