The Santa Cruz Bullit Carbon C 90 is engineered for riders who crave big days on the most demanding trails. At its heart is a Carbon C MX chassis, meticulously crafted for strength, lightness, and confidence at speed. Santa Cruz’s 4-bar suspension layout delivers exceptional traction, bump absorption and control, helped along by 170mm of travel front and rear.
The Bullit’s power comes from a Bosch Performance Line CX motor, offering a class-leading 85Nm of torque to boost you up the steepest trails with ease. The 600Wh integrated battery gives solid range out of the box, and if you're hungry for more, the frame is compatible with Bosch’s 250Wh range extender.
The suspension package is fully trail-ready with a FOX 38 Float Performance fork and a FOX Float X Performance shock, tuned for e-MTB needs. Together they offer big-hit capability without sacrificing agility. Complementing this, the Bullit’s flip-chip system lets you fine-tune both the bike’s geometry and suspension progression, adapting the bike to your riding style and terrain.
Shifting is handled by the precise and robust SRAM GX Eagle T-Type 12-speed drivetrain, built for the rigours of e-bike torque. Stopping power is guaranteed with SRAM Maven Base 4-piston brakes, giving superb control even on steep, technical descents.
Wheels are no compromise either, with Reserve 30|HD AL rims wrapped in Maxxis Assegai 29x2.5" up front and Minion DHRII 27.5x2.5" at the rear offers the ideal mix of grip, support and manoeuvrability for aggressive riding.
This bike isn’t just about raw power either. The OneUp V3 dropper post offers massive drop, perfectly paired with the Bullit’s improved insertion and sizing. Meanwhile, Bosch’s user interface keeps things simple and clutter-free, with wireless control and a clean cockpit.
If you want a high-performance e-MTB that climbs effortlessly, descends like a beast, and feels absolutely bombproof doing it, the Santa Cruz Bullit Carbon C 90 is ready for your wildest rides.
