Torque Sensor Technology
Ride Naturally with an Advanced Torque Sensor
Smooth power that feels like an extension of your own legs.
The Core ST 2.0 27.5" features an advanced torque sensor that measures the force you apply to the pedals and instantly delivers matching motor assistance.
Instead of the sudden, on-off feeling common with basic cadence sensors, torque-sensor assist feels smooth, controlled, and natural. It gives you better handling in traffic, easier starts from stoplights, and a more confident ride on hills.
Because power is delivered only when you need it, the system also helps improve battery efficiency — making it ideal for longer commutes and everyday riding.
- Smooth, natural feel
- Better handling in traffic
- Effortless stoplight starts
- Longer battery range

Easy Boarding with a Comfortable Step-Through Frame
The step-through frame makes getting on and off the bike simple and comfortable. Whether you are commuting in work clothes, running errands, or carrying cargo on the rear rack, the low-step design helps make every ride easier.
It is especially practical for riders who want a more accessible, confidence-inspiring commuter eBike without sacrificing strength, style, or daily utility.
Go Farther with a 48V 12Ah Removable Battery
Powered by a 48V 12Ah removable battery, the Core ST 2.0 27.5" is built to support longer commutes, weekend rides, and daily errands without constant recharging.
The battery is integrated into the frame for a clean look and can be easily removed for convenient charging at home, in the office, or on the go. Paired with the energy-efficient torque sensor, it helps stretch every charge farther by delivering power only when your pedaling effort calls for it.
Range Note
Range may vary based on rider weight, terrain, temperature, cargo load, tire pressure, assist level, speed, and throttle use.
1200W Peak Power for Hills, Starts, and City Speed
A powerful 1200W peak motor gives the Core ST 2.0 27.5" the muscle to handle steep city hills, quick starts from traffic lights, and everyday stop-and-go riding.
With up to 80Nm of torque and a Class 3 top speed of up to 28 mph, this commuter eBike helps you move through the city with confidence while reducing the effort needed to reach your destination.
Whether you are climbing hills, carrying groceries, or cruising through your daily route, the motor delivers reliable support when you need it most.
Smooth Out Rough Roads with Adjustable Front Suspension

Lock it out for efficient riding on smooth roads, or open it up for extra comfort on uneven surfaces. The result is a smoother, more controlled ride that helps reduce fatigue on longer commutes.
