The Upgraded Core 2.0 for Smoother, Longer City Rides
Meet the Core 2.0 27.5" — the smarter evolution of the classic Core 2.0 commuter eBike. Built for riders who prefer a traditional step-over frame, this upgraded model adds torque-sensor assist, a larger 48V 12Ah battery, and smooth-rolling 27.5" wheels to deliver a more natural and capable city ride.
Compared with basic cadence-style assist, the torque sensor responds to how hard you pedal, giving you smoother starts, better control in traffic, and more efficient power use on longer commutes. Paired with a 1200W peak motor, 80Nm of torque, and up to 100 miles of PAS range, the Core 2.0 27.5" is made for riders who want more from every daily ride.

Torque Sensor Technology
Natural Power That Responds to You
Smooth, controlled assist that matches your pedaling effort in real time.
The Core ST 2.0 27.5" uses an advanced torque sensor to measure how hard you pedal and adjust motor assistance to match your effort.
Instead of the sudden on-off push common with basic cadence sensors, torque-sensor assist feels smooth, natural, and easy to control. It helps you start more confidently from stoplights, ride more steadily through traffic, and climb hills with less effort.
Because power is delivered only when your pedaling calls for it, the system also helps improve energy efficiency — making it ideal for longer commutes, grocery runs, and everyday city riding.
- Smooth, natural pedal assist
- Better low-speed control
- Easier stoplight starts
- More efficient power use
Torque Sensor vs. Cadence Sensor — Feel the Difference

- Less refined at low speeds, turns, or in traffic
- Drains the battery faster
- Feels like "the bike is dragging you along"

Range Disclaimer
Range may vary based on rider weight, terrain, temperature, assist level, speed, cargo load, tire pressure, and throttle use.
Classic Step-Over Frame for Confident Control
The Core 2.0 27.5" keeps the classic step-over frame design that many riders prefer for its familiar feel, balanced control, and strong commuting posture. This frame style gives the bike a more traditional ride character, making it a great choice for riders who want efficient city travel with a sportier edge.
With balanced geometry, a 65.1 lbs frame, and a comfortable riding position, it is designed for daily commuters who want stability, control, and confidence on busy streets.
Suitable for riders from 5'3" to 6'2"
1200W Peak Motor for City Speed and Hill Support
The 1200W peak motor gives the Core 2.0 27.5" the power needed for quick starts, steady cruising, and confident hill climbing. With up to 80Nm of torque and a Class 3 top speed of up to 28 mph, it helps reduce effort on demanding city routes.
Whether you are climbing moderate hills, carrying daily essentials, or moving through stop-and-go traffic, the motor delivers smooth and reliable support when you need it.
Smoother Rolling with 27.5" Wheels and Front Suspension
The upgraded 27.5" x 2.1" tires help the Core 2.0 27.5" roll more smoothly and maintain momentum better than smaller city wheels. They provide a stable, efficient feel for commuting speeds while helping absorb everyday road texture.
An adjustable front suspension fork adds another layer of comfort by softening bumps, cracks, and uneven pavement. Lock it out for efficient riding on smoother roads, or open it up when the route gets rough.
