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 Plus 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

Cadence Sensor
- Only detects whether the pedals are turning
- Power kicks in abruptly — sudden surges
- Less refined at low speeds, turns, or in traffic
- Drains the battery faster
- Feels like "the bike is dragging you along"

Ride in Ultimate Comfort
From your wrists to your arms, back, hips, spine and knees—designed to reduce pressure while you ride. An upright riding position means better posture, less pain, more confidence, and lasting comfort.
Go Farther with a 48V 12Ah Removable Battery
With a 48V 12Ah removable battery, the Core ST 2.0 Plus is designed to take you farther on every ride, delivering up to 100 miles of range on a full charge. From daily commutes to weekend rides and everyday errands, you can enjoy extended riding time with fewer charging stops.
The battery is integrated into the frame for a clean, modern look and can be easily removed for convenient charging at home, at work, or on the go. Combined with the energy-efficient torque sensor, it helps make every charge go farther by delivering power based on your actual pedaling effort.
Range & Riding Time Note
Actual range and riding time may vary depending on rider weight, terrain, temperature, cargo load, tire pressure, assist level, speed, riding mode, stop-and-go traffic, wind conditions, and throttle use.
1200W Peak Power for Hills, Starts, and City Speed
The 1200W peak motor delivers up to 80N·m of torque, providing extra support for quick starts, headwinds, and hills with up to 35% climbing capability. Whether you're leaving an intersection or heading uphill on your commute, the motor gives you the power to keep moving with less effort.
Paired with the torque sensor, motor assistance responds to how hard you pedal, creating a more natural connection between your effort and the power you receive. With a top speed of up to 28 MPH, the Core ST 2.0 Plus is built for everyday commuting and longer city rides.
Smooth Out Rough Roads with Adjustable Front Suspension
City roads are not always smooth. That is why the Core ST 2.0 Plus 27.5" is equipped with adjustable front suspension to help absorb bumps, cracks, and rough pavement.
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.
Easy Boarding with an Ergonomic Step-Through Frame
The low-step, step-through frame makes getting on and off the bike simple and comfortable, especially when commuting in work clothes, running errands, or carrying cargo on the rear rack.
A swept-back curved handlebar helps create a more upright riding posture, bringing your upper body closer to a natural 90° position. This ergonomic setup helps reduce pressure on your back, shoulders, and wrists, so you can stay comfortable and feel less tired during longer daily rides.
Built for accessibility, comfort, and everyday utility, the Core ST 2.0 Plus is ideal for riders who want a commuter eBike that feels easy to mount, stable to ride, and comfortable for extended use.

FAQs

What makes the Core ST 2.0 Plus different from the original Core ST 2.0?
The Core ST 2.0 Plus upgrades the everyday commuting experience with a torque sensor, larger 27.5" × 2.1" tires, and a 48V 12Ah removable battery. The torque sensor adjusts motor assistance based on how much force you apply to the pedals, creating a more responsive and natural pedal-assist feel.
How does the torque sensor change the riding experience?
The torque sensor measures how much force you apply to the pedals and adjusts motor assistance accordingly. Pedal lightly and the motor provides lighter support; pedal harder and the system responds with more assistance. This makes power delivery feel more closely connected to your own pedaling effort, especially during starts, hills, and stop-and-go city riding.
How far can the Core ST 2.0 Plus travel on one charge?
The Core ST 2.0 Plus can provide up to 100 miles of range with pedal assist under ideal riding conditions. Actual range varies with assist level, speed, rider and cargo weight, terrain, temperature, tire pressure, wind, stop-and-go riding, and throttle use.
How fast can the Core ST 2.0 Plus go?
The Core ST 2.0 Plus supports pedal-assisted speeds of up to 28 MPH. Actual riding speed may vary with rider weight, terrain, battery level, and riding conditions. Always follow applicable state and local eBike regulations.
Can the Core ST 2.0 Plus handle hills?
Yes. The 1200W peak motor and 80N·m of torque provide additional support for everyday hills, quick starts, and riding with cargo. For climbing, shift into a lighter mechanical gear and increase pedal assist as needed to keep your pedaling effort manageable.
How long does it take to charge?
Charging takes approximately 6–7 hours with the included 54.6V / 2A charger. The removable battery can be charged separately from the bike, making it convenient to recharge at home, at work, or wherever a suitable outlet is available.
Who is this eBike best for?
The Core ST 2.0 27.5" is ideal for riders who want a comfortable step-through commuter eBike with smoother pedal assist, longer range, and better stability for daily city riding.
Can I ride the Core ST 2.0 Plus in light rain?
The Core ST 2.0 Plus has an IPX5 water-resistance rating and is designed to handle splashes and light rain. Avoid prolonged exposure to heavy rain, deep water, or high-pressure washing, and make sure the battery, charging port, and electrical connections are dry before charging.
Does the Core ST 2.0 Plus arrive fully assembled?
The bike arrives partially assembled. Basic setup is required, including installing components such as the front wheel, handlebars, pedals, and accessories. Tools and a user manual are included to help with assembly.
