What goes up, loves coming down

The Bullit is an electric mountain bike designed for tackling the steepest and deepest of trails in both directions. Imagine the kinds of rooty, rocky, horror fests usually reserved for our biggest hitting bikes like the Nomad and Megatower. Then imagine what lies beyond that.

Where the Heckler's priority is agility and playful handling, the Bullit takes a more no limits approach. 170mm travel, a 38mm fork and DoubleDown tires reflect the smashability of this platform. This is a bike for riders who seek V10 level terrain that's out of range of any chairlift or shuttle road.

It was actually the Santa Cruz Syndicate team's success on their mixed wheel DH race bikes that made us consider the same format for the Bullit. We learned from them that mixed wheels provide the confidence at speed of a 29er with the more spritely handling characteristics and maneuverability of a 27.5-inch rear wheel. And for an e-bike, it also means we can dictate exactly how long (or short) we want to make the chainstays to balance climbing traction and handling. The added butt clearance on super steep stuff is just another bonus.

The biggest trails take a bigger commitment to reach them. Thankfully Shimano's commitment to the STEPS EP8 motor means we have a lighter, more powerful (85nm), more compact and more efficient way of reaching them. The EP8 is also tuned to give more power in Trail mode without affecting range. So paired with Shimano’s biggest 630wh battery it ensures the Bullit is fully equipped for long, tough climbs to the longest, toughest descents.

Frame Sizing

If you're on the cusp between the recommended height range of two sizes, the absolute best thing is to try to ride them both. At a minimum, check the stack/reach measurements on your current bike and compare it to the new model you are looking at to get an idea of a fit you are already comfortable with. If riding the bike is not an option, consider the following.

Personal Preference

A larger size frame will be more stable, and will give you more room to move without upsetting the weight-balance of the bike. The larger size will put the front wheel further in front of you, which gives the feeling of security and conversely, it will require more significant body movements when you WANT to shift the weight-bias of the bike. Think hard about your riding style and how active/intuitive you want it to be vs stable and speedy. You'll need to work a bit harder to muscle the larger bike around.

Body Dimension

Not all bodies at a given height are the same. If you have longer legs and a shorter torso than the average person your height, that may push you towards the smaller of the recommended sizes. If you're all torso and arms, most likely you'll want to size up.

Mix of Both Worlds

The mixed wheel configuration of a 29-inch wheel up front provides traction and stability, while the 27.5" rear wheel keeps agility at hand and the chainstay length in-check.

170mm VPP Travel

170mm travel front and rear, a burly 38mm diameter fork and DoubleDown tires reflect the smashability of this platform.

Full CC Carbon Frame

Other bikes in this category rarely adopt carbon because few companies have mastered carbon manufacturing. Our carbon frames are designed in our Carbon Lab in California, made in our own facility by our team and have a lifetime warranty.

Santa Cruz Carbon Di2 Bar

There's nothing worse than an untidy cockpit. Our own bar hides the extra cables of the Shimano STEPS system away, keeping things clean and hassle free.

Shimano STEPS EP8 Motor and 630wh Battery

More power, less weight, even more efficient and the biggest battery Shimano offer.

Quality, Strength, Reliability

The legendary Santa Cruz fit, finish and quality construction make this long-range hauler tough enough to handle anything. The frame, linkages and optional Reserve wheels come with a lifetime warranty.

Can I run a dual crown fork on the Bullit?

No, this is not compatible. Full stop.

For even more information, visit the ebike FAQ's page.

Can you run the Bullit full 27.5"?

You can, but definitely not recommended. It would reduce BB height, pedal to ground clearance and negatively affect handling characteristics.

What rear shock can I run?

Shock size is 230mm x 62.5mm, but we tune the OE rear shock specifically for the Bullit model

Where can I find additional technical information for my Bullit?
