Battery
The 252 Wh battery (36V / 7Ah) is built into the rear pannier rack. It is removable for easy transport.
It can be locked with a key to prevent it from being stolen.
The battery has a 2-year warranty.
The bike is sold with its battery, charger, and 2 keys.
Battery life: 3 assistance modes.
- Eco mode: up to 50 km of battery range. It compensates for the bike's weight and allows you to go further.
- Normal mode: up to 40 km of battery range. It helps you easily deal with false flats and gives you an extra push when riding into the wind.
- Boost mode: up to 30 km of battery range for travelling faster at 25 km/h and dealing with steep bridges.
The battery life varies depending on the tyre pressure, gradient, conditions, and weight of the user and their bags.

Connectivity
Download the Decathlon Mobility app and turn your smartphone into a smart dashboard with live tracking and Auto Mode.Review the history and battery usage of your rides after you’ve finished, and manage your bike’s maintenance with ease (tutorials, workshop appointments, updates and insurance).
For a greater range with an extra battery
You can of course buy an extra battery if you are going to be doing long rides with a lot of kilometres and/or over several days.
/!\ note:
The 36 V, 11.6 Ah battery (417 Wh capacity) is also compatible and provides between 45 and 70 km of battery life. It is available from after-sales service (ref: 8669826).
Motor
The brushless motor is located in the rear hub and provides 35 Nm of torque with a maximum power of 250 W.
The speed at which the motor will accelerate you up to 25 km/h depends on how hard you pedal and the mode that you have selected on the control screen.
A cadence sensor triggers this assistance when you pedal.
System to keep the bike folded
We've chosen to use a strap to hold the bike in position when folded. It also means that you can push the bike along in its folded position if you need to.
This system is simple and effective.
This rubber strap (elastomer) is fixed to the rear pannier rack and can be clipped to the stem to hold everything together.
We have performed durability tests on this strap: 2400 cycles (1200 plugs / 1200 unplugs) with a pulling force of 13 Nm.
Frame
Hi-Ten steel frame to keep you comfortable. The easy lateral-fold system means the bike takes up little space and fits anywhere: at home, at the office, in the boot of a car or in a campervan. In fact, you'll forget your bike is even there.
In order to improve your bike's stability once folded, the frame is equipped with a bike stand under its base.
Fork
Hi-ten rigid steel fork for greater durability.
TRANSMISSION
* Equipped with a Shimano Tourney 6-speed derailleur to help you overcome any little difficulties you encounter on your ride (steep bridges, pushing off at red lights at a low speed). Changing gears is very easy using the grip shifter.
* 52T chainring.
* Shimano 6-speed freewheel (14/28). - smallest development: 2.96 m per turn of the pedals, 28 teeth
- largest development: 5.90 m for every pedal turn, 14 teeth.
Pedals / Chainset
* Fold-up pedals to reduce bulk when the bike is folded. Once the pedals are folded up and the stem folded down, the bike can be stored against a wall and takes up very little space.
* Aluminium chainring with 170 mm cranks
* Double chainring guard to stop the chain jumping and to protect it from dirt.
BRAKES
The aluminium V-Brake calipers guarantee effective and progressive braking.Aluminium brake levers.
Remember: The brake pads on electrically-assisted bikes wear down more quickly than a classic bike due to the weight and power of the motor.You will need to adjust your brakes regularly to keep them working reliably.
Stem / Handlebar
- Stem: aluminium, and the height can be adjusted to suit the rider and keep them comfortable as they ride.
Adjusting the height of the stem changes the angle of your back and position of your arms.
- Handlebar: steel. 22.2 mm diameter.
The grips have an ergonomic shape for greater comfort. You can change the incline based on your height.
Saddle / Seat post
Saddle wide, comfortable, seamless foam saddle.
Seatpost: aluminium. 31.6 mm diameter. It is marked to make it easier to adjust, with grooves to guide it and ensure that the saddle is always straight.
There is also a special "theft-proof" device so that the saddle can't be easily lifted off without tools.
WHEELSET
20 inches.
Double-walled rims for greater durability and machined walls for better braking performance.
Steel hub with ball bearings.
TYRE
* 20 x 1.75.
* Skinwall technology for better durability, efficiency and grip.
* Tyre sidewalls:
- reflective bands to make you visible at night
- brown for a vintage look
To reduce the risk of getting a puncture, optimise your battery range and enjoy a more efficient ride, we recommend inflating your tyres to 4.5 bar.
This is the maximum pressure for your tyres.
We recommend checking your tyre pressure every three weeks.

The lights are powered by the bike's battery.
- Front light power: 15 lux
- Rear light power: 5.4 lumens
You can turn them on and off by pressing the button on the control screen.

Care advice
Tyres lose pressure over time. On average, they lose 1 bar/week.
So remember to regularly pump up your tyres:Riding with under-inflated tyres reduces your battery range, requires more pedalling effort, and increases the risk of punctures.
Before performing any work on your electric bike (cleaning, electrical or mechanical maintenance), you must turn off your electric bike and remove the battery.
If you are not using your bike over the winter, charge it at least every 3 months.
Battery care and storage advice
/!\ Store / charge your battery in a dark, dry, cool place (+10°C to +25°C).
Do not store your battery when low on charge (1 flashing LED) as this could lead to a deep discharge which could affect its capacity.
Remember to charge the battery (even when you're not using it) at least every 3 months to prevent it going into a deep discharge.
If you can't charge your battery regularly, switch it to sleep mode, even though it goes into sleep mode automatically after two hours.
GUARANTEE
B'Twin offers a lifetime warranty on the frame (excl. hinge), stem and handlebar.Parts: 2 years, excluding wear and tear.
