2026 Santa Cruz Bullit 4 C GX AXS

The 2026 Santa Cruz Bullit 4 C GX AXS is made for riders who want to get deep into technical trails, charge big descents, and tackle serious mountain terrain with confidence. This bike blends Santa Cruz’s sharp geometry and aggressive stance with a well-thought-out Bosch motor system and next-level electronic shifting. The result feels precise and powerful in every situation.

Suspension

Up front, a Fox 38 Float Performance Elite fork with Grip X2 damping and 170mm travel smooths out rough, rocky terrain and big hitswith ease. At the rear, the Fox Float X Performance Elite shock keeps traction where you want it. This makes long, steep descents and technical climbs easier to manage.

Drive System

The SRAM GX Eagle AXS T-Type drivetrain makes gear changes crisp and instant. The wireless derailleur never hesitates, even when you’re powering hard uphill. Using a short 155mm crankset means more ground clearance, which is perfect for an e-bike on gnarly trails. The flattop chain and wide 10-52 tooth cassette give you a huge gear range to handle whatever the mountain throws your way. The SRAM AXS Pod shifter keeps your cockpit clean and your shifting right under your thumb.

Brakes

You'll also find a set of SRAM Maven Bronze brakes paired with 200mm rotors front and rear. Expect strong, controlled braking that you can trust during fast descents or technical scrambles.

Wheels and Tires

Reserve 30 HD aluminum rims stand up to serious abuse on rough terrain. E13 SL hubs designed for e-bikes keep your wheels turning smooth and reliable. Tires feature a smart mixed setup. A Maxxis Assegai 29x2.5 with 3C MaxxGrip compound on the front provides fantastic grip. The rear rolls on a 27.5x2.5 Maxxis Minion DHRII with 3C MaxxTerra. It's a bit narrower but tough and traction-rich where it counts.

Cockpit

The OneUp aluminum bar is wide (800mm) and rises 35mm, tipping the scales in favor of control on steep, tricky descents. A 42mm OneUp stem tightens handling without feeling twitchy. The OneUp dropper post drops low when you need it on the fly and climbs smoothly. The saddle is an SDG Bel-Air V3 Max Lux-Alloy Atmos, made with a balance of comfort and trail feel. Cane Creek 50 IS headset keeps the front end tracking clean and precise.

Motor and Battery

Powered by a Bosch Performance Line CX motor, the Bullit offers 85Nm of torque. The motor’s assist feels smooth and natural. It's never too aggressive but always there when you need it. The battery is a 600Wh Bosch PowerTube integrated cleanly inside the downtube. You get solid range without bulky battery weight or awkward placement.

If you want a bike that dives into rough terrain and climbs back up with the same hunger, this Bullit is ready. Do not expect compromises. Expect precision, power, and confidence all the way through.
