"Ultimate Portability. Uncompromised Ride."
The Cyrusher Sonder is the ultimate solution for urban mobility and travel. It combines a lightweight, quick-folding frame with the premium features of a full-sized e-bike, including a surprisingly plush suspension system and an intuitive torque sensor. Whether you're commuting to work, exploring a new city on vacation, or simply need a bike that fits your life (and your trunk), the Sonder delivers a smooth, powerful, and convenient ride without compromise.
This Is The Tool For You If...
- You are a city commuter who needs a bike that's easy to store at home or the office.
- You love to travel and want a capable e-bike that can fit in your car or RV.
- You have limited storage space but don't want to sacrifice ride quality.
- You appreciate a bike that is lightweight, nimble, and easy to manage.
Folds in Seconds
Compact & Portable Design
The Sonder's greatest strength is its ability to shrink. With a few simple steps, the frame folds neatly in half, the handlebar stem collapses, and the pedals fold up. This transforms the bike into a compact package that can be easily carried, stored in a closet, placed under a desk, or loaded into the trunk of a car. It's the perfect companion for a life on the move.
Smooth, Natural Power
Intuitive Torque Sensor
Unlike basic cadence sensors that just detect if you're pedaling, the Sonder's advanced torque sensor measures how hard you're pedaling. This allows the motor to deliver power that's perfectly proportional to your effort. The result is an incredibly smooth and natural-feeling ride, as if your own strength is being amplified. It makes for seamless acceleration and intuitive control.
