Answers to common questions
How much does it weigh?

How much torque does it have?
It has 80 Nm of torque from a hub motor. That is exactly the median for its class. It should handle hills reasonably, but hub motors have limits on steep climbs.
What speed class is it?
It is a standard pedelec class. That means pedal assist up to 25 km/h. There is no throttle. You must pedal to get assistance.
How far does it really go?
The manufacturer claims 80 km. Our estimate is 68 km, based on a reference ride. That estimate is 15% below the claim. Use the range calculator to adjust for your own conditions.
What does it cost to run?
The price is 2148 USD, which is 38% above the class median. Running costs depend on electricity and maintenance. The battery is large, so charging may cost more than smaller batteries. Use the cost calculator to estimate yearly costs.
Where it falls short
The main trade-off is weight. At 40 kg, it is 17% heavier than the class median. That extra weight comes from the large 1200 Wh battery. It makes the bike harder to carry, lift, or ride without power.
Who should buy it
The Coswheel CT20S is for riders who prioritize range and torque over portability. It fits long commutes or trail rides where charging is not easy. It is not for anyone who needs a light bike or a compact one.
- Riders who want a large battery for long trips without recharging.
- Riders who need strong torque for hilly terrain.
- Riders who do not need to lift the bike often.
Look elsewhere if you need a light e-bike for carrying or a foldable model for storage. The 40 kg weight and lack of folding make it impractical for those uses. Also, if 2148 USD is above your budget, consider a bike closer to the 1554 USD median.
