Pivot Shuttle SL/AM Pro X0 Eagle Transmission

The motor is a Bosch Performance Line SX, which Bosch positions as its lightest and most compact e-bike motor, putting out up to 600 watts of peak power and 55Nm of torque from a compact 400Wh in-frame battery. That's a smaller battery and lower peak output than a full-size Bosch Performance CX system, and it's a deliberate tradeoff: less weight and a more natural, bike-like feel underfoot rather than maximum range or maximum assist. Riders who want more range can add Bosch's optional PowerMore 250 range extender, a bottle-shaped 250Wh unit that mounts to the frame and weighs about 3.3 pounds. The Pivot x Bosch Flow app controls the system and offers seven ride modes, including Turbo, an eMTB-shortcrank mode, Sport, and Tour+, along with maintenance reminders and real-time range estimates.

The frame itself borrows its all-mountain DNA from Pivot's non-motorized Switchblade, carried over into a carbon chassis with 150mm of rear travel and Pivot's dw-link suspension design, paired with a Fox Factory 36 fork running 160mm of travel up front. Pivot builds this XS size with mixed 27.5/29-inch wheels, a first for this platform, specifically aimed at giving smaller riders proper handling and confidence rather than a scaled-down version of a bike built for a taller rider. Suspension tuning is aimed at quick, efficient climbing without giving up composure on rough, technical descents, which is the balance a lighter e-MTB has to strike since it can't lean on raw power to make up for a soft, wallowy chassis.
