Questions people ask
How much does it weigh?
The Coswheel Y20L weighs 28 kg. That is slightly below the median for folding e-bikes. You will still feel it when carrying. Plan for a sturdy rack or a ramp if you lift it often.
How much torque does it have?
Torque is 75 Nm. That is 50% above the class median. This motor is a hub type. It should handle moderate hills without strain. Strong torque helps if you are a heavier rider or carry cargo.
What speed class is it?
It is a standard pedelec class. Top speed is 25 km/h. There is no throttle. You pedal to get assistance. That keeps it legal in many places without registration.
How far does it really go?
The manufacturer claims 150 km. MathBikes estimates 52 km. That estimate is 65% below the claim. The estimate comes from a formula, not a test. Use the range calculator to adjust for your own conditions.
What does it cost to run?
The price is 1014 USD. That is 5% below the median for its type. Running costs depend on electricity and maintenance. The battery is 720 Wh, which is larger than average. A larger battery may cost more to replace. Use the cost calculator to compare long-term costs.
Where it falls short
The biggest gap is between claimed and estimated range. The claim is 150 km, but the estimate is 52 km. That is a 65% difference. You should not expect to ride 150 km on a single charge. The estimate is based on a standard ride, not a test.
Who should buy it
This bike fits riders who value torque and battery capacity in a folding package. It is priced below the median for its class. It is not for everyone, though.
- You commute under 50 km per day and want strong hill assistance.
- You need a folding bike for mixed commutes, like train and road.
- You want a larger battery than most folding bikes offer.
Look elsewhere if you need a true long-range bike. The estimated range is 52 km. Also, there is no throttle and no step-through frame. Check the warranty, as it is not published.
