Product Details
The Santa Cruz Bullit C 90 is built for riders who want maximum capability when the trail points steeply downhill and the terrain becomes unforgiving. Designed as a high performance enduro eMTB, it pairs 170mm of front and rear travel with a robust carbon frame platform to deliver a bike that is equally comfortable charging technical descents, riding rough alpine terrain, or handling high speed shuttle laps. It is engineered to provide confidence, control, and durability in the most demanding riding environments.
At its core, the Bullit C 90 features a lightweight yet highly durable C Carbon frame that is purpose built for aggressive eMTB riding. The frame is paired with a Bosch Performance CX motor system that delivers powerful, natural feeling pedal assistance for steep climbs and sustained efforts on long, technical ascents. A Bosch PowerTube 600Wh battery is seamlessly integrated into the frame, providing a balanced ride feel and dependable range for big mountain missions.
Suspension performance is handled by a FOX 38 Float Performance fork with Grip damper and 170mm of travel, matched with a FOX Float X Performance rear shock. This combination is tuned to absorb heavy impacts while maintaining composure through repeated hits and high speed chatter. The result is a planted, controlled feel that keeps the bike stable and predictable even when the terrain gets unpredictable.
The SRAM 90 Eagle T-Type 12 speed drivetrain provides smooth, precise shifting under load, ensuring reliable gear changes whether climbing steep fire roads or pedaling out of technical corners. Stopping power comes from SRAM Maven Base brakes paired with large 200mm HS2 rotors front and rear, delivering consistent braking performance and strong modulation on long descents. A OneUp V3 dropper post allows quick saddle height adjustment for improved control on descents and efficiency on climbs.
Rolling on Reserve 30|HD AL rims with e13 SL E-Spec hubs, the Bullit C 90 is built for durability and impact resistance. It is paired with a mixed wheel setup using a Maxxis Assegai 29x2.5 front tire and a Maxxis Minion DHRII 27.5x2.5 rear tire, delivering a balance of traction, stability, and maneuverability across varied terrain.
Purpose built for speed, control, and rugged reliability, the Bullit C 90 is a full power eMTB designed to handle the most demanding trails with confidence.
