Eunorau Specter-ST 2.0 Step-Through Electric Mountain Bike

The EUNORAU SPECTER-ST 2.0 is a full-suspension step-through electric mountain bike designed for trail riding, mixed terrain, and riders who want easier mounting without giving up powerful mid-drive assistance. Its 18.5-inch 6061 aluminum-alloy frame is paired with a 140mm-travel suspension fork and DNM rear shock.

Powered by a Bafang G510/M620 48V 1,000W mid-drive motor producing up to 160 Nm of torque, the SPECTER-ST 2.0 uses a torque sensor to provide assistance based on pedaling input. Its 48V 17.5Ah main battery can be supplemented by a compatible optional second battery for extended riding range.

The SPECTER-ST 2.0 features 27.5 x 3-inch tires, an SRAM NX 11-speed drivetrain, 180mm hydraulic disc brakes, a thumb throttle, adjustable stem, Bafang DPC18 color display, and integrated front and rear lights. It supports a maximum payload capacity of 300 lb and is recommended for riders from 5'3" to 6'4".
