Questions people ask about the Duotts S26
How much does it weigh?
The Duotts S26 weighs 39.8 kg. That is 16% above the median weight for its type. It is a heavy e-bike. You will feel the weight when lifting it or maneuvering it without power.
How much torque does it have?
The motor delivers 65 Nm of torque. That is 19% below the median torque of 80 Nm. It is a hub motor, not a mid-drive. Expect adequate acceleration, but not class-leading hill-climbing power.
What speed class is it?
It is a standard pedelec class. The top speed is 25 km/h. There is no throttle. You pedal to get assistance, and the motor stops helping at that speed.
How far does it really go?
The manufacturer claims a range of 120 km. MathBikes estimates a real-world range of 54 km, with a band of 48 to 61 km. That estimate is 55% below the claim. The estimate comes from a formula, not a test. You can adjust the inputs with the range calculator.
What does it cost to run?
The purchase price is 1284 USD. Running costs depend on electricity and maintenance. The battery is large, so charging costs more than a smaller battery. Use the cost calculator to estimate yearly expenses. The warranty is not listed, so factor that into your decision.
Where it falls short
The Duotts S26 is heavy and has below-average torque. At 39.8 kg, it is 16% heavier than the median bike. The 65 Nm motor is 19% weaker than the median. These two factors make it less agile and less capable on steep climbs.
Who should buy it
This bike fits riders who value battery capacity and upfront cost over weight and power. It is a sensible choice for flat or rolling terrain where torque matters less. If you want a light bike for technical trails, look elsewhere.
- You want a large 960 Wh battery for long rides without recharging.
- You are on a budget and want a price below the median for its class.
- You ride mostly flat routes and do not need maximum torque.
Skip this bike if you need to carry it upstairs or load it on a car rack. Also skip it if you ride steep hills regularly. The weight and torque numbers work against you in those situations.
