The device described in the manual is an electrically-assisted bicycle, specifically the B'TWIN TILT 500E model. It is designed for leisure travel, urban commuting, and fitness, offering both practicality and an economical mode of transport.
Function Description:
The B'TWIN TILT 500E is an electrically-assisted bicycle that provides pedal assistance to the rider. It can be used with or without electrical assistance, activated by an ON/OFF button. The electrical assistance only engages when the rider pedals and automatically switches off if either brake lever is depressed or the speed exceeds 25 km/h. It will restart automatically when the speed drops below 23 km/h. To preserve battery life, the bike incorporates a "power" limiter that reduces assistance when the motor is under heavy strain. In extreme conditions or intensive use, the assistance may temporarily switch off to protect the system. The bike is heavier than classic pushbikes, and pedaling without assistance can be more challenging. Users are advised to ensure they can complete their journey without assistance in case the battery runs flat.
Important Technical Specifications:

- Age Recommendation: Designed for persons aged 14 and over.
Usage Features:
- Assistance Modes: The bike offers four assistance modes: Off, Eco, Normal, and Sport, each corresponding to a different maximum assistance speed. These modes are selected via a "MODE" button on the control screen.
- ON/OFF Functionality: The bike is switched on and off with a short press of the ON/OFF button.
- Lighting Control: A dedicated "light" button allows the user to switch the bike's front and rear LED lights on and off.
- Battery Level Indicator: The control screen displays the battery level with four indicators. When the battery level is too low, the indicator will flash. The battery level indicator is more accurate when the bike is at a complete stop.
- Battery Security: The battery must always be locked with a key when in use.
- Battery Insertion/Removal: To insert the battery, unlock the slot with the key and ensure no foreign objects are present. To remove, unlock the slot and lift the battery loop. It is crucial not to attempt insertion or removal when the loop is lowered (vertical position) to avoid damaging the security lock.
- First Use: The battery must be fully charged to 100% before its first use.
- Charging Recommendation: Recharging the battery after each use is recommended.
- Charging Indicator: The LED on the charger is red when charging starts and turns green when charging is complete. A flashing red LED indicates a charging problem, requiring contact with after-sales service.
- Environmental Considerations: Cold weather reduces battery life. Overloading the bicycle or cycling uphill will also reduce battery life.
- Safety: Users are advised to learn how to use the bike in an open area to get accustomed to the motor's feel. Only use sport mode initially if confident in controlling the bike. Always wear a helmet. Be aware that in rain, frost, or snow, tyre traction may be reduced.
Maintenance Features:
- Battery Storage: Store the battery charged and in a dry, cool place (between +10°C and +25°C), out of direct sunlight. Do not store a discharged battery to prevent deep discharge and malfunction. For extended storage, recharge the battery once every 3 months.
- Battery Charging Environment: Charge the battery in a dry environment at a temperature between +10°C and 40°C. Only charge indoors.
- Battery Lifespan: The battery is guaranteed for 2 years or 500 charging and discharging cycles (1 cycle = 1 charge from 0% to 100% + 1 discharge from 100% to 0%), provided proper use and storage conditions are met. After 500 cycles, the capacity and autonomy of the battery are reduced.
- General Maintenance:
- Always carry out maintenance operations in sufficient light.
- Before each use, ensure brakes and the electric system are working properly.
- All cleaning and electrical or mechanical maintenance must be performed with the power switched off and the battery removed from the bike.
- Maintenance operations specific to the electric system must be performed by trained, qualified staff.
- If the chain comes off, turn the power off before attempting repairs.
- Prohibited cleaning methods: high-pressure jet.
- Not recommended cleaning methods: running water.
- Recommended cleaning methods: damp sponge.
- Wheel Removal: If a wheel is removed, ensure the direction of rotation is correct upon reinstallation.
- Rims and Motorised Wheel: Rims are subject to wear and must be checked for integrity. The motorised wheel is reinforced but subject to higher stress; if a spoke breaks, contact a DECATHLON store.
- Impact Check: If the bike or battery falls, check the battery for integrity. The watertightness of the battery may no longer be guaranteed after a fall.
- Professional Service: It is advisable to bring the electrically-assisted bike to a DECATHLON store for its 6-month service.
- Electrical Component Maintenance: Maintenance of electrical components requires special skills and is carried out in Decathlon regional workshops, which may take several days.
- Battery Handling Precautions:
- Do not expose to temperatures exceeding 50°C.
- Never dismantle the battery.
- Do not immerse in water.
- Do not clean with a high-pressure washer.
- Do not dispose of the battery in non-suitable containers; return used batteries to a Decathlon store for recycling.
- Risk of fire and electrocution.
- Handle with care; the product is sensitive to impacts.
- Never short-circuit the battery by connecting positive and negative terminals.
- Never permit children to play with or handle the battery.
- Ensure the battery and charger are compatible.
- Ensure the charger is compatible with the local electrical grid (100 V, 240 V maximum) and frequency (50 Hz minimum, 60 Hz maximum).
- Transport by aeroplane is prohibited.
- Failure to comply with precautions will void the manufacturer's warranty.
The bicycle has a lifelong guarantee on structural components (frame, handlebar stem, handlebar, and saddle-pillar). Other parts are guaranteed for 2 years against normal wear and tear. The warranty does not cover damage from misuse, failure to respect precautions, accidents, improper use, or commercial use. It also does not cover damage from unauthorized repairs or cracked/broken screens. Opening or modifying sealed electronic components voids the warranty. To validate the lifetime warranty, the buyer must either have a DECATHLON loyalty card with the purchase registered or complete an online warranty certificate within one month of purchase, providing personal and bicycle tracking information. Travel and transportation costs for warranty repairs are the customer's responsibility. The warranty does not apply in cases of poor maintenance or misuse.
