Battery
The 252Wh (36V/7Ah) battery is integrated into the rear luggage rack. It is removable for easy transport.
It can be locked with a key to prevent theft.
Lifespan: 500 complete cycles (1 cycle = recharge from 0 to 100%). Beyond 500 recharge cycles, the battery still works but not at the maximum of its initial capacities.
Warranty: 2 years. The battery and charger are supplied with the bike.
Battery can be ordered for more autonomy (ref: 8669826).
Autonomy: 3 assistance modes.
- ''Eco'' mode: up to 50km of autonomy. It compensates for the weight of the bike and allows you to go further.
- ''Normal'' mode: up to 40km of autonomy. It allows you to easily pass false flats and helps you against the wind.
- ''Boost'' mode: up to 30km of autonomy to go faster at 25km/h and cope with bridge climbs.
The autonomy varies according to the tire pressure, the relief, the conditions of use and the weight of the user and their load.
Display
LED control screen.
3 assistance modes: eco, normal, boost.
Indication of the remaining autonomy level via a 5-bar gauge.
Different buttons allow you to control essential functions:
- ''on/off'' button to turn the screen on and off.
- button with the lighting logo to turn the front and rear lights on and off simultaneously.
- a ''+'' and a ''-'' button to change the assistance modes.
Connected via Bluetooth.
Connectivity
Download the app and unleash the full potential of your bike!
The app is compatible with:
-For Apple devices: iOS 8 and higher
-For Android phones: Android 7 and higher.
To add autonomy with an additional battery
You can of course buy an additional battery if you are going to do long rides with a lot of kilometers and/or over several days.
/!\ to know:
The 36V 11.6 Ah battery (capacity 417Wh) is completely compatible and gives you between 45 and 70 km of autonomy.
Engine
The Brushless motor is located in the rear wheel and offers 35 Nm of torque for a maximum power of 250W.
By pedaling, the motor takes you to 25 km/h more or less quickly, with more or less force depending on the mode selected on the control screen.
This assistance is triggered by pedaling thanks to a system of pedaling frequency sensors.
Folded bicycle support system
We have chosen a strap to keep the bike in the folded position for storage. This also allows you to roll the bike in folded mode whenever you want.
This system is simple and effective.
This rubber strap (= elastomer) is attached to the rear luggage rack and will then clip onto the stem to hold the assembly.
We have carried out resistance tests on the strap: 2,400 cycles (1200 plugs/1200 unplugs) with a pulling force of 13Nm.
Frame
Hi-Ten steel frame for comfort.
The side folding system allows for a small footprint: at home, in a car trunk, camper van... your bike knows how to be forgotten.
In order to improve the stability of the bike once folded, the frame is equipped, under its base, with a bike rest.
Fork
Rigid Hi-Ten steel fork for added strength.
Transmission
* Equipped with a Shimano Tourney 6-speed derailleur, it will help you overcome the few difficulties you will encounter on your journey (climbing bridges, starting at a red light with an easier speed). Changing gears is very simple thanks to the rotating handle.
* 52-tooth chainring.
* Shimano 6-speed freewheel (14/28).
- smallest development: 2.96 m per pedal revolution, 28 teeth
- largest development: 5.90 m per pedal revolution, 14 teeth.
Pedals / Crankset
* Folding pedals to reduce the size of the folded bike.
Once the pedals are folded and the stem folded down, the bike can be stored along a wall with reduced space requirements.
* Aluminum crankset with 170mm cranks
* Double chainring guard to prevent derailments and protect against dirt.
Brakes
Aluminum V-brake calipers provide efficient and progressive braking.
Aluminum brake levers.
Good to know:
Electrically assisted bicycles use more brake pads than a conventional bicycle due to the weight and power of the motor.
It is necessary to adjust your brakes regularly for good braking quality.
Stem / Hanger
- Stem: made of aluminum, it is adjustable in height to adapt to everyone and have more comfort while riding.
This adjustment allows you to manage the inclination of your back and the position of your arms.
- Handlebar: made of steel. Diameter 22.2mm.
The handles have an ergonomic shape for more comfort. You can change the inclination according to your height.
Saddle/Seat post
Saddle: wide and comfortable in seamless foam.
Seat post: aluminum.
Diameter 31.6 mm.
It is graduated to facilitate adjustment, a groove guides you during handling and ensures that your saddle is always straight.
An "anti-theft" stop exists to prevent the saddle from being easily removed without tools.
Wheels
20 inch.
Double wall rims for added strength and machined sidewalls for improved braking performance.
Steel hub with ball bearings.
Tires
* 20 x 1.75.
* Skinwall technology for more resistance, efficiency and grip.
* Tire sides:
- reflective strips to be visible at night
- brown for the vintage look
To limit the risk of punctures, have better performance and optimal autonomy, we recommend inflating your tires to a pressure of 4.5 BAR.
This corresponds to the maximum inflation pressure of your bike.
We advise you to check the pressure of your tires every 3 weeks.
Lighting
The lights are powered by the bike's battery.
- Front light power: 15 Lux
- Rear light power: 5.4 Lumen
You can choose to turn them on or off by pressing the button on the control screen.
Please note:
They comply with the French and German standards, which are the most demanding.
For your safety, even if your battery has no more autonomy, the front and rear lights will remain on for another 2 hours.
Accessories and equipment
- Integrated rear luggage rack + tensioner included.
- Integrated front carrying interface to accommodate the 25L folding bike specific bag (ref: 8735484 / release date March 2023).
- Height-adjustable kickstand to adapt to the inclination of the ground and your transported loads (front bag, panniers, etc.).
- Front and rear mudguards.
- Bell.
Compatibility
COMPATIBLE with:
- the 25L front bag that clips in 1 second. It is specific to Btwin folding bikes. The specific carrying interface is directly integrated at the front on the bike frame (ref: 8735484 / release date March 2023).
- the city bike bags on the rear luggage rack.
- the metal basket (ref: 8365778) on the rear luggage rack.
- the 20" protective cover (ref: 8271631).
/!\ NOT COMPATIBLE with:
- baby seat.
- child trailer.
Bike weight
The bike weighs 21.4 kg (battery + motor included).
Its steel structure and its equipment provide a lot of comfort at the expense of the weight which is a little more important.
This bike is not designed to be worn frequently and for a long time.
Wear it only to go up a few steps or to put it in a car trunk and in the hold of the camper.
The rest of the time the bike can be rolled in folded mode; the handle under the saddle provides you with comfort.
User height and maximum load
The geometry of this bike offers optimal comfort for cyclists measuring between 1.45 m and 1.95 m.
This bike meets the requirements of the ISO 4210 standard.
The maximum weight is 110 kg (cyclist + bike + luggage).
Compactness
Folded (L/H/W): 84 x 73.5 x 46 cm.
Unfolded (L/H/W): 145 x 113 x 64 cm.
Maintenance tips
The pressure in your tyres decreases over time. On average, the loss is 1 BAR/week.
Remember to re-inflate your tyres regularly: riding with a low air pressure reduces your battery life, increases your pedalling effort and encourages punctures.
Before carrying out any work on your electric bicycle (cleaning, electrical or mechanical maintenance), remove your battery and switch off your EAB.
If you are wintering, charge your battery at least every 3 months.
Battery care and storage tips
/Store/charge your battery in a cool (between +10°C and +25°C), dry place away from direct sunlight.
Do not store the battery discharged (1 LED flashing) to avoid any deep discharge that could impair its capacity.
Remember to recharge the battery (even when not in use) at least every 3 months to avoid deep discharge.
If you can't charge your battery regularly, switch it to standby mode, even if 1 automatic standby occurs after 2 hours.
