Santa Cruz Bullit 4 - Bosch CX - Carbon C - GX AXS - Gloss Purple

The Downhill Bike with a Built-in Chairlift

If you feel the pull of gravity riding but want an extra push to get to the top, the Bullit is for you. It features a Bosch Performance Line CX motor to get you to the drop-in of the wildest trails. Built tough for the toughest terrain, the Bullit is the closest you can get to owning both a downhill bike and a chairlift.

Job #1: Exceptional Handling

Every chassis engineering decision was to make this bike handle like few other bikes do. It’s the obvious things like bombproof, lightweight carbon frame, superior ebike suspension performance and tailored geometry. But it’s also the little details, things like having a seatstay bridge and one-piece link to keep it tracking straight, enclosed downtube instead of removable battery cover to allow us to tune the material mass in the frame.

The Most Travel

With 170mm travel front and rear it’s the closest thing to a downhill bike without strapping a dual-crown fork on. The Bullit takes a no-limits approach to ebikes. 

The Mighty Bosch

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.

Range Versatility & Uncompromised Handling

It’s got 850 Wh…kinda. 600 Wh under the hood and an optional 250 Wh PowerMore range extender provides the freedom to go far. But on the regular days where the main battery is enough (you know, 1400-1800m of vert) you don’t have to carry around extra heft. Handling excellence was at the heart of every design decision, so finding that weight sweet spot was a primary parameter.

System Control

The entire Bosch system is beautifully integrated, simple, yet advanced. Tiny, ergonomic, wireless remote control, wireless speed sensor, and a dialed display make living easy. The Bosch app allows you to fully customize modes, upload routes, track rides, and even let the Range Control select modes for you.

Made To Last Many Lifetimes

Strength is prioritized over skimping on bearings, layup, or inadequate parts. We save weight through streamlined design instead, with all builds sub-50lb. Like all Santa Cruz bikes, the pivots and links are tough, reliable, and easy to maintain. Plus, owners get lifetime replacement bearings. Bikes aren't throwaway items, but they get thrown around. That’s why ours are made to last many lifetimes. 

Independent Tuneability

There’s two flipchips, one for progression and one for geo. The geo chip raises or lowers the BB 4mm, and adjusts the headtube angle 0.3-degrees. The progression chip changes the progression, which allows you to fully dial in your ride. 

Why Four-Bar? Why Not VPP?

The four-bar suspension system has already been 'Vala-dated'. To recap – the VP-Free approach allows packaging of the motor, greater seat post insertion, and, most importantly, gets the suspension characteristics we want. That last bit is important, because when you’re heels down, head up hauling down a truly exciting trail, you’ll appreciate how well the Bullit handles. 

Proportional Geo

The steepest seattube and slackest headangle (63-degrees) we’ve put on any bike made to be pedaled. That means you can sit up when climbing, but hunker down when it comes to the return journey. Chainstay length set to frame size, ensuring balanced geometry for every rider, regardless of height.

First Small Bullit (And Still Available in XXL)

Yup, the first time we’ve made a small one. And it comes with MX wheels setup like every size. There’s no compromise for the smaller riders. And the tallest folk are looked after because it goes up to a massive XXL.
