Bullit C Eagle 90 E-Bike

What Our Gearhead® Experts Are Saying:

"I’ve never felt so confident charging downhill at full speed. The FOX 38 fork paired with Reserve wheels and double casing tires is perfect for sending it big. Bosch’s Performance CX motor makes climbing fun again, and SRAM's Maven brakes blew me away with their modulation and sheer power. This build is next-level dialed."

The Bullit C MX 90 is a purpose-built e-MTB for riders who blur the line between big-mountain freeride and self-supported exploration. Designed around Santa Cruz’s Carbon C frame with 170mm of travel, its 4-bar suspension design delivers efficient pedaling on the way up and incredible composure when bombing down. Mixed wheels—a 29" front and 27.5" rear—optimize rollover and responsiveness, while Reserve 30|HD AL rims with Maxxis DoubleDown tires offer pro-level durability.

At the heart of this build is the Bosch Performance CX drive unit paired with a 600Wh PowerTube battery. It delivers instant torque and natural power delivery whether you’re winching up techy climbs or cruising fire roads. The FOX 38 Float Performance fork and Float X shock soak up everything from braking bumps to big hits, while SRAM's T-Type drivetrain ensures confident gear shifts across demanding terrain.

This “Kit 90” version upgrades the stopping power with SRAM Maven Base brakes and includes a OneUp dropper, OneUp alloy bar, and E13 Helix cranks. The drivetrain uses a SRAM GX Eagle T-Type chain for increased longevity under high-torque loads. Whether you're racing enduro, pushing your limits at the bike park, or exploring backcountry trails, the Bullit C MX 90 is your go-to e-MTB for big moves and bigger days.
