The Cyrusher Sonder is a folding e-bike with a 480 Wh battery and a 22.2 kg weight. It is 22% lighter than the median folding bike, which weighs 28.6 kg. That makes it one of the lighter options in its class. It suits riders who need a portable bike for mixed commutes or storage in tight spaces.

The Sonder has a hub motor and a top speed of 24 km/h. It is a standard pedelec, so it assists only while you pedal. The manufacturer claims a range of 85 km, but MathBikes estimates 35 km. You can see how that estimate is made with the range calculator.

Questions people ask about the Cyrusher Sonder

How much does it weigh?

The Sonder weighs 22.2 kg. That is 22% below the median for folding bikes. It is a practical weight for lifting onto a train or into a car boot.

How much torque does it have?

The motor torque is not listed. Most folding bikes have around 50 Nm, but the Sonder does not publish a figure. Without that number, you cannot compare its hill-climbing ability directly.

What speed class is it?

It is a standard pedelec class, with a top speed of 24 km/h. That means the motor assists up to that speed, and you must pedal to get assistance. There is no throttle.

How far does it really go?

The manufacturer claims 85 km, but MathBikes estimates 35 km. That estimate is 59% below the claim. The estimate comes from a formula using a reference ride, not a real test. The actual range depends on your weight, terrain, and assist level.

What does it cost to run?

The price is 1122 USD, which is 5% above the median for folding bikes. Running costs include electricity and maintenance, but the warranty is not listed. You can estimate your own costs with the cost calculator.

Where it falls short

The Sonder's battery is 29% below the median capacity for its class. That directly affects range, which is 27% below the class median. If you need a long-distance commuter, this bike may not be enough.

Who should buy it

The Sonder fits riders who value portability over range. It is a practical choice for city dwellers with limited storage or for mixed-mode commutes.

  • You need a bike that folds for a bus or train ride.
  • Your daily trip is under 35 km and you can charge at work.
  • You want a lighter bike to carry up stairs.

Look elsewhere if you need a long range or a throttle. The Sonder is not built for those needs.
