Clip. Lock. Ride.

Compatibility first: round seatpost only, 25–35 mm diameter, with at least 50 mm of straight mounting space.
Natural pedal support
Power That Responds as You Pedal
Smart sensing adjusts assistance to your riding movement, helping reduce effort while keeping the familiar feel of your own bicycle.
Powerful Edition
Four Modes for Four Different Rides
Each mode changes how the motor responds. Select modes through the app or controller on the Powerful Edition.
01 · Assist Mode
A Natural Push When You Pedal
Assistance responds to cadence and riding conditions. Pedal faster or meet a slope and the system adds support, helping starts and climbs feel easier without taking away the familiar cycling feel.
02 · Cruise Mode
Hold a Comfortable Pace
After pedaling to the activation speed, Cruise Mode maintains steady assistance while you continue riding. Adjust the target level from the controller for relaxed commuting on open routes.
Cruise availability and maximum assisted speed depend on local regulations. Use only where permitted.
03 · Workout Mode
Turn the Road into Your Training Session
The motor adds controlled resistance, creating a more demanding workout. During suitable riding conditions, regenerative resistance can return a small amount of energy to the battery.
04 · Standby Mode
Your Bicycle Still Rides Like a Bicycle
Pause powered assistance whenever you want and continue riding normally without removing the unit—useful when conserving battery or riding through restricted areas.
Lite Edition includes Assist Mode and Standby. Cruise Mode and Workout Mode require the Powerful Edition.
Daily commuting
Ride Farther Without Arriving Exhausted
The 158Wh Lite battery delivers up to 50 km of assistance under ideal test conditions. The 220Wh Powerful Edition extends ideal range up to 70 km.
Actual range changes with rider weight, terrain, temperature, tire type, speed and assistance level.
USB-C PD3.0
Fast Charging—and Power for Your Gear
Recharge in about 3 hours for the 158Wh battery with a compatible 65W USB-C PD charger. The Type-C port can also output up to 100W to compatible phones, lights and portable devices.
65W USB-C wall charger is not included. A Type-C charging cable is included.
BMS protection
Built for Safer Everyday Power
The removable lithium battery uses multi-layer management against overcharge, overheating, excessive discharge and short circuit. It is designed to retain around 80% capacity after 1,000 cycles.
IPX5 splash resistance
Ready for Changing Commutes
Splash-resistant construction handles light rain and wet-road spray. The anti-slip drive roller helps maintain contact when the road surface changes.
Do not submerge the unit or charge it while wet.
Powerful Edition safety
Smart Protection When a Ride Goes Wrong
Assistance cuts when excessive tilt is detected. The Powerful Edition can use fall detection and send an SOS location alert through a connected phone.
SOS requires the Powerful Edition, compatible app setup, phone connection and an emergency contact.
Check before ordering
Will It Fit Your Bicycle?
Designed for many 14–29 inch road, hybrid, mountain and folding bicycles—but frame and tire clearance matter more than wheel size alone.
Not suitable for children’s bicycles, carbon-fiber seatposts, D-shaped seatposts, rear-suspension bicycles, tricycles or wheelchairs. No rear rack or fender may block the unit. The roller must align with the center of the rear tire.
250W rated · 500W peak
Compact Power for Starts, Hills and Headwinds
The friction-drive motor delivers smooth daily assistance with up to 500W peak output when extra help is needed. The adaptive control changes support instead of forcing one fixed power level.
Remote + App
Control the Ride Without Guesswork
The Powerful Edition controller lets you raise or lower assistance, pause power, switch modes, operate turn signals and connect the intelligent e-brake. The app adds guided calibration, mode selection, firmware updates and fault checks.
App availability, road-mode settings and some functions can vary by phone and region.
Regenerative workout
Pedal Against Resistance—and Recover Energy
Workout Mode uses motor resistance for training and can recover approximately 1–3% battery per kilometre under suitable conditions. Results vary with terrain, bicycle and riding habits.
V-shaped drive roller
Reliable Contact, Replaceable Wear Part
The textured V-shaped roller is designed for grip across common road and mountain tires and is rated for approximately 3,000–5,000 km of use before replacement, depending on setup and conditions.
Intelligent e-brake
Motor Power Cuts When You Brake
With the Powerful Edition brake sensor connected, squeezing the brake lever immediately interrupts motor assistance for more predictable control in traffic and on descents.
Rear safety light
Be Easier to See and Understand
The built-in rear light improves visibility after dark. On the Powerful Edition it can brighten during braking and provide left/right turn indications from the controller.
App-enabled convenience
Setup, Updates and Diagnostics in One Place
Automatic installation calibration helps align the system. The app can adapt available settings to local traffic rules, switch riding modes, install OTA updates, create riding groups and run remote fault detection.
CalibrationGuided setup for correct power delivery.
Local RulesAdjust supported limits by region.
OTA UpdatesKeep system firmware current.
DiagnosticsCheck faults before the next ride.

Frequently asked
Before Your First Ride
Is this a complete electric bicycle?

Can I ride without assistance?
Yes. Switch to Standby to ride like a normal bicycle without removing the unit.
Does the 65W charger come in the box?
No. A charging cable is included, but the compatible 65W USB-C PD wall charger is sold separately.

No. Those advanced controls are available on the Powerful Edition. Lite provides Assist Mode and Standby.
