Santa Cruz Bullit CC X0 AXS RSV 2027
The Santa Cruz Bullit CC X0 AXS RSV brings together a full carbon EMTB chassis, long-travel suspension, and a top-tier component package, all centred around Bosch’s latest Performance CX drive system. Built using Santa Cruz’s CC-grade carbon frame, this model is designed around a mixed wheel (MX) platform with 170mm of front and rear travel, delivering a setup that’s clearly focused on capability, control, and durability on demanding terrain.
At the heart of the bike is the Carbon CC MX 170mm 4-bar frame, paired with a FOX Float X2 Factory rear shock (205x65) and a FOX 38 Float Factory fork with GRIP X2 damper. This combination represents FOX’s highest-level suspension offering, with Kashima-coated internals and a wide range of adjustment, giving riders the ability to fine-tune the bike to suit different trails and riding styles. The 170mm travel front and rear places the Bullit firmly in the long-travel e-MTB category based on the figures alone.

Bullit 2027 Update
For the 2027 model year, the power delivery remains centered on the field-proven Bosch Gen 5 Performance Line CX motor and the lightweight, integrated 600Wh PowerTube battery. While the drive system stays consistent, the Carbon CC frames have undergone a critical evolution.
Every 2027 CC-tier frame now features a specialized internal routing architecture specifically engineered to support a shift toward a fully hardwired ecosystem. This major update ensures that all electronic rear derailleurs are powered directly by the bike’s main drive unit, providing a seamless, "always-on" ride experience. By drawing energy straight from the 600Wh battery, this integrated setup sheds unnecessary weight and completely eliminates the need for peripheral batteries, ensuring your bike is as streamlined as it is powerfu

Bosch Performance Line CX Gen 5
The Bosch Performance Line CX is powerful, reliable and quiet. The power on tap and how it delivers it makes going up trails feel like descending. Or just gets you to where you can actually ride a real downhill trail. Now delivering up to 100Nm.
UNCOMPROMISED HANDLING & RANGE VERSATILITY
Reliability, powerful, wireless, the right size battery, and range extender.

Santa Cruz Quality
Santa Cruz Bicycles has built its reputation on producing high-performance mountain bikes with a strong focus on engineering, durability, and rider-focused design, and the Bullit sits firmly within that identity. As part of their e-MTB range, the Bullit represents a long-travel platform built around modern electric drive systems, while still following the same design principles seen across the brand’s wider lineup. Known for its use of advanced carbon frame construction and refined suspension layouts, Santa Cruz applies that same approach here, pairing a full-power e-bike platform with a specification that reflects the brand’s emphasis on quality and consistency across every component.

MIXED WHEELS RIGHT FOR EBIKES
Better handling for ebikes - counteracts the extra weight of battery by providing rearward bias for best handling
Provides more freedom in chainstay length - size specific chainstay lengths, especially good for shorter riders.
