Vala C Eagle 90 E-Bike

What Our Gearhead® Experts Are Saying:

"I was blown away by how natural the Bosch Performance CX motor feels on the Vala C MX 90. It’s super intuitive—especially in eMTB mode—and when paired with the Float X and Reserve wheels, it rides like a regular bike with bonus legs. It's fast, fun, and actually makes me want to ride longer days."

The Vala C MX 90 Mountain Bike brings a new level of capability to the e-MTB category with a balanced 4-bar suspension design and Bosch Performance CX power system. Delivering 150mm of rear travel, this carbon-framed machine keeps us in control on the descent and energized for every climb. The 29-inch front wheel adds stability and confidence at speed, while the 27.5-inch rear wheel keeps handling tight and responsive in tech.

The Bosch Performance CX BDU38 motor generates up to 85Nm of torque and integrates seamlessly with the 600Wh PowerTube battery, giving riders smooth, reliable power for long, rugged rides. Suspension duties are handled by a FOX 38 Float fork and Float X Performance rear shock, offering mid-stroke support and big-hit absorption. SRAM’s 90-series Eagle T-Type drivetrain and Single Click shifter give us eMTB-specific shifting that holds up under serious force, while the E13 Helix eSpec crankset keeps everything dialed and strong.

This build rolls on Reserve 30|HD alloy wheels with Maxxis tires—EXO+ up front, Double Down in the rear—giving us confidence in rocky terrain and hard corners. Add in a OneUp dropper, bash guard, and SRAM Maven Base brakes with 200mm HS2 rotors, and you get a fully capable, trail-devouring eMTB that rides like a bike and climbs like a machine.

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.
