Santa Cruz Bicycles Vala C Eagle 90 E-Bike

Power through tech with the Vala C MX 90 Mountain Bike and Bosch Performance CX drive

What Our Gearhead® Experts Are Saying:

"I’ve taken the Vala C MX 90 out for big elevation days, and it’s made every ride more fun. The Bosch Performance CX motor delivers smooth power with tons of torque for punchy climbs, and the mixed wheels keep it agile in the tight stuff. The Float X shock feels great under load, and the Reserve wheels bring peace of mind when things get rowdy."

We ride the Vala C MX 90 when we want to explore deeper, climb farther, and stay out longer. This mixed-wheel eMTB uses a carbon frame, 150mm of rear travel, and Bosch’s Performance CX drive system to bring punchy acceleration and precise trail handling together in one package. Whether we´re cleaning steep climbs or dropping into rugged descents, the Vala keeps us energized and in control.

The FOX 38 fork and Float X rear shock deliver a smooth, planted ride feel at speed and across loose terrain. SRAM’s T-Type 12-speed drivetrain with e-bike-specific Single Click shifter helps us stay dialed even under max torque, while the 600Wh Bosch PowerTube battery keeps the juice flowing. A mixed set of Reserve alloy wheels and Maxxis tires—with DoubleDown protection in the rear—deliver grip and reliability for long trail missions. This build is ready for serious pedal-assisted adventures.

Heads up — We do our best to keep bike specs and images current, but occasional component changes can happen without warning—and sometimes the photos might not show the exact build you’ll receive. If you want to double-check the details, our Gearheads are always here to help.
