The Bullit 4 is Santa Cruz’s most capable eMTB yet — a full-power enduro machine that rides like a downhill bike and climbs like it’s got something to prove. With 170mm of travel, mixed wheels, and SC’s most aggressive geometry to date, it’s built to handle steep, technical descents with composure and control. And thanks to the Bosch Performance Line CX system, it gets back to the top without missing a beat.
Every detail of the Bullit 4 has been engineered for abuse, precision, and repeat sendability — from the oversized bearings and enclosed downtube to the size-specific geometry and dialed 4-bar suspension. It's the bike for riders who want it all: big travel, big power, and the freedom to ride more trails, more often.
FEATURES:
-
170mm Front & Rear Travel: Maximum suspension travel delivers true downhill performance — plush on the hits, planted in the chunk.
-
Bosch Performance Line CX Motor: With 85 Nm torque and 600 watts peak power (Now user upgradeable to 120 Nm torque & 750 watts peak power), this system delivers a smooth, powerful ride with quiet, responsive performance, smart display, wireless controls, seamless Bosch Flow App integration, and proven reliability.
-
Aggressive, Adjustable Geometry: Slackest HTA (63.3°) and steepest STA (up to 78.7°) of any SC eBike, with flip chips for both geometry and progression tuning.
-
Durable Carbon Frame: Available in C and CC options under 50 lbs, with oversized bearings, one-piece link, and reinforced frame details.
-
Mixed-Wheel Setup: 29" front / 27.5" rear for playful, nimble handling that counterbalances the battery’s weight for confident descents.
-
Ride-Ready Details: Tool mount under the toptube, long dropper compatibility, and no-special-tools serviceability.
