Understanding the motor and battery in 30 seconds
250 W
Power
This is the legal power limit in Europe: all approved electric bikes are rated at 250 W. So it is not what makes the difference between two bikes.
Nm
Torque, in newton-metres
The motor’s real strength: what pushes you when setting off and on hills, with the bike loaded. For a family cargo bike, aim for 60 Nm or more; 80 Nm or more climbs anything, even loaded.
Wh
The tank, in watt-hours
The size of the energy tank: the more watt-hours, the further you go. Actual distance depends on terrain and load — see the gauge below.
How far does the battery go? Choose your route
This model’s exact capacity is to be confirmed: choose a capacity to see the order of magnitude.
Fine-tune with the slider: the load carried, the assistance used and the weather matter as much as the gradient.
Everyday city use
≈ 45 km
with 500 Wh
City with a few hills, intermediate assistance, one child or the shopping.
Why from green to red? The closer to red, the harder the motor works: hills, the weight carried, strong assistance, wind and cold all use more energy. The same battery that covers about 65 km in the green covers noticeably less in the red.
Indicative, rounded estimate for comparison: actual range also depends on the bike, the motor, the rider and maintenance. Describe your route to us and we will advise you on the battery and torque you need.
What do I need for my daily use?
Tell us about your use: the motor and battery you need take shape. The higher the gauges climb towards red, the more strength and range your use requires.

Indicative estimate, with a 30% reserve so you do not finish the day with a flat battery and to allow for the cold. Describe your route to us: we will confirm the right choice.
The battery = the tank
Its capacity is measured in watt-hours (Wh): voltage (V) multiplied by amp-hours (Ah). More Wh means more kilometres between charges, but neither more speed nor more power.
The motor = the strength
What matters is torque, in newton-metres (Nm): it makes the difference when setting off, on hills and with children or a load. For an electrically assisted bicycle, European law limits power to 250 W and cuts assistance at 25 km/h: maximum assisted speed is therefore the same for all; a higher-torque motor reaches it more easily, even when loaded.
Range = your use
With the same battery, range varies a lot depending on the assistance level chosen (from Eco to Turbo), hills, the weight carried, average speed, wind, tyre pressure and cold weather, which reduces capacity.
