Eunorau SPECTER-ST 2.0: The Ultimate Full-Suspension Step-Thru

Elite Mid-Drive Performance Meets Accessible Design

The Eunorau SPECTER-ST 2.0 is the pinnacle of high-performance e-biking, combined with the accessibility of a step-thru frame. At its heart lies the legendary Bafang G510 (M620) motor, widely considered the "king" of mid-drives. Delivering a massive 1000W of power and a staggering 160 Nm of torque, this bike provides the raw strength to conquer the steepest mountain peaks while maintaining the refined, intuitive feel that only a true torque sensor can provide.

Master Any Terrain with Full Suspension

The SPECTER-ST 2.0 is built for riders who refuse to compromise on comfort or control.

• Trail-Ready Suspension: Equipped with a massive 140mm travel front suspension fork and a DNM AO-38RC rear shock, this bike creates a "cloud-like" ride over rocks, roots, and urban potholes.

• Smart Torque Sensing: The integrated torque sensor measures your pedaling force 1,000 times per second, delivering power that feels like an extension of your own legs. No more jerky starts—just smooth, predictable, and instantaneous acceleration.

• High-Speed Versatility: With a top speed of 28 MPH and 27.5" x 3.0" plus-sized tires, you get the perfect balance of agility for technical trails and stability for high-speed road commutes.

Enthusiast-Grade Components

• SRAM NX 11-Speed Drivetrain: Navigate any grade with precision. The SRAM NX 11-42T wide-range cassette is paired with motor shift detection, which momentarily cuts power during gear changes to protect your chain and ensure buttery-smooth shifts.

• 4-Piston Hydraulic Braking: To manage its high-speed capabilities, the bike features a sensitive 4-piston hydraulic disc brake system. This provides significantly more stopping power and heat dissipation than standard 2-piston brakes.

• Dual Battery Capability: Conquer long-distance missions with up to an 80-mile range. The SPECTER-ST 2.0 supports a secondary battery setup, allowing you to stay out on the trails longer than ever before.

• Custom Fit: The adjustable handlebar stem allows you to fine-tune the height and angle of your cockpit, ensuring an ergonomic and fatigue-free riding position for every journey.

Frequently Asked Questions

Why is the Bafang M620 (G510) motor so highly rated?

The M620 is a "heavy-duty" mid-drive motor. Unlike smaller motors that might overheat on long climbs, the G510 is built with a massive internal core and a true torque sensor. It produces 160 Nm of torque—more than some small car engines—allowing it to power up 45-degree inclines with ease.

How does "Shift Detection" protect the bike?

Mid-drive motors pull directly on the bike's chain. Without shift detection, the 1000W motor could potentially snap a chain during a gear change. The SPECTER-ST 2.0 includes a sensor that tells the motor to "pause" for a fraction of a second when you click the SRAM shifter, ensuring your gears transition smoothly and your drivetrain lasts longer.

What is the advantage of 27.5" x 3.0" tires?

These are known as "plus-sized" tires. They are wider than a standard mountain bike tire but more agile than a 4-inch fat tire. They offer incredible traction and bump absorption while allowing the bike to remain responsive and easy to lean into corners at high speeds.

Can I adjust the bike's performance for street versus trail?

Yes. The Bafang DPC18 Color Display allows you to toggle through 5 levels of pedal assist. You can use lower levels for a natural, calorie-burning workout on paved paths, or crank it to level 5 for maximum power when tackling technical off-road climbs.

Is the step-thru frame strong enough for off-roading?

Absolutely. The SPECTER-ST 2.0 frame is constructed from reinforced 6061 aluminum alloy specifically engineered to handle the high torque of the M620 motor and the rigors of trail riding. The step-thru design simply makes it easier to mount and dismount, which is especially helpful on uneven terrain.
