Questions people ask about the Coswheel M20
How much does the Coswheel M20 weigh?
The Coswheel M20 weighs 32 kg. That is 7% below the median weight for its type, which is 34.5 kg. So it is lighter than the typical mountain e-bike in this database. But 32 kg is still a heavy bike to lift or carry.
How much torque does the Coswheel M20 have?
The motor torque is 50 Nm. That is 37% below the median for its type, which is 80 Nm. Lower torque means less climbing power on steep trails. If you ride mostly flat ground, this may not matter much.
What speed class is the Coswheel M20?
The speed class is not listed. The top speed is 45 km/h. That is the highest speed figure given for this bike. Without a speed class, you cannot know how it is legally classified in your area. Check local rules before you buy.
How far does the Coswheel M20 really go?
The manufacturer claims 84 km. The MathBikes estimate is 41 km, with a band of 36 to 46 km. That estimate is 51% below the claim. The estimate uses one reference ride for every bike on the site: Tour assist, rolling terrain, mild weather, brisk pace, an 80 kg rider. It is not a measurement. Use the range calculator to see how your own weight and route might change it.
What does the Coswheel M20 cost to run?
The price is 949 USD. That is 37% below the median price for its type, which is 1499 USD. The battery is 720 Wh, which is 14% below the median battery of 840 Wh. Running costs depend on your electricity price and how often you charge. The warranty is not listed, so you cannot know what repairs might cost after purchase. Use the cost calculator to work out your own running costs.
Where it falls short
The Coswheel M20 gives up torque to hit its price. At 50 Nm, it has 37% less torque than the median for its type. That means it will struggle more on steep climbs than a typical mountain e-bike. Its estimated range is also 15% below the median. And the manufacturer claimed range of 84 km is 51% above the MathBikes estimate of 41 km. That is a big gap between claim and estimate.
Who should buy it
The Coswheel M20 suits riders who want a mountain e-bike at a low price and do not need strong climbing torque. It has a 750 W rated motor and a throttle, which helps on hills without pedaling. Its 32 kg weight is below the median for its type. But it is not a light bike, and its estimated range is below the median.
- You ride mostly flat or rolling terrain and do not need high torque for steep climbs.
- You want a full-size mountain e-bike and your budget is below the median price of 1499 USD.
- You use a throttle to help on hills and do not mind pedaling with less motor assistance.
Look elsewhere if you need strong climbing torque, because 50 Nm is 37% below the median. Look elsewhere if you need a long estimated range, because 41 km is 15% below the median. And look elsewhere if you need a published warranty or a known speed class, because neither is listed for this bike.
