Your First Ride

Important Note

⚠️ VERY CAREFUL: Your e-bike moves significantly faster than a regular bicycle in active power-assisted mode. For your first ride, take the e-bike to an area with plenty of open space. It is recommended to start with the pedal assist off to familiarize yourself with braking and gear shifting. Gradually test pedal assist levels to find optimal settings for your riding style.

Safety Checks Before Every Ride

• The battery pack must be charged and installed correctly.
• The display must be on and functioning properly.
• The brakes must be working properly.
• Tires must be inflated to the proper psi.
• The front and rear lights must be working properly.
• Cable connections must be secure.

Operating Your New E-Bike

1. Power On: Press the power button on the left handlebar until the display lights up.
2. Start Riding: Ride the bike and twist the throttle bar or pedal. The bike will move. You can change the power level with the control buttons (Level 1 is the slowest, Level 5 is the fastest, Level 0 is human model).

Other Functions

Hand Throttle Control

In hand throttle mode, power assist is determined by the throttle. Twist the throttle away from its resting position for more power to accelerate. Release the throttle to slow down and apply brakes if necessary. You do not need to pedal when using the hand throttle. Pedaling while using power assist conserves energy and extends battery life.

Security and Warnings

Before Riding the E-BIKE

Always perform a mechanical inspection before riding:

• Hardware is properly secured.
• Tires are properly inflated.
• Brakes are working properly.
• Handlebars are adjusted and fixed.
• Front wheels are secure and properly locked.

When Riding the E-Bike

• Obey all road rules and local traffic laws.
• Respect motorists, pedestrians, and other cyclists. Do not race or taunt others.
• Ride cautiously; others may not see you. Maintain a safe distance from other cyclists or vehicles.
• Ride on bike lanes and trails where available.
• Obey traffic stop signs and signals.
• Use appropriate gestures when turning and parking.
• Do not wear headphones.
• Do not carry adult passengers unless the bike is designed for it.
• Do not carry anything that obstructs your view or control of your e-bike.

Avoid Riding in Certain Situations

• Visibility is poor (dawn, dusk, dark).
• Bad weather.
• Extreme rider fatigue.
• When e-bike maintenance is required.

Off-road Riding

• Obey local laws regarding off-road riding.
• Practice riding on easier terrain to enhance skills.
• Always wear proper safety gear.
• Ride with a companion in the backcountry.

Riding in the Rain

• Avoid riding in wet weather as much as possible.
• Reduce your speed if you must ride in wet weather.
• Wet weather affects visibility, braking, and traction.
• Accidents increase in wet weather conditions.

Riding at Night

• Riding at night is more dangerous than during the day.
• Be sure to wear reflective clothing.
• Obey local laws regarding night riding.
• Reflectors supplement, but do not replace, required lights. Ensure reflectors are in good condition. Do not remove them.
• Always use an adequate lighting system when riding at night or in poor visibility. Inadequate lighting can result in serious injury. Equip your e-bike with aftermarket batteries or a generator lighting system if necessary.

Extreme and Aggressive Riding

Electric bike designs have limitations. Extreme, stunt, and competition riding may exceed these limits. The manufacturer does not recommend these types of rides, as they increase the risk of death and serious injury.

Battery and Maintenance

Charging Your E-Bike Battery

1. Open the cover of the charging port and fold the bicycle.
2. Insert the key into the battery and hold it down until it is screwed clockwise to the end. Ensure the lock lever is fully retracted.
3. Slide off the battery (handle with care as it is heavy).

Battery Charging Information

• You can charge the battery while installed or removed from the e-bike.
• Turn off the battery before charging.
• Charging time is approximately 6 hours for a fully discharged battery. The charger's LED changes from red to green when fully charged. Disconnect the charger at this point.
• Do not leave the charger connected for extended periods after charging is complete.
• It is normal for the charger and battery to heat up slightly during charging. If unusual activity occurs, stop charging and contact Engwe Bikes Product Support.

Tips for Increasing Range

The bike's range varies based on rider, terrain, wind, user input, and cargo weight. To maximize range per charge:

• Ride at a lower PAS level.
• Use lower PAS levels and pedals when climbing hills.
• Pedal when starting from a standstill.

Battery Recycling

When your battery is no longer usable, dispose of it according to state and federal regulations. Lithium-ion batteries cannot be placed in standard trash cans.

Recommended Maintenance Interval

Regular inspection and maintenance are crucial for your ENGWE bike's performance and longevity. The suggested intervals are for guidance; actual needs may vary. Inspections, service, and replacements are recommended at the following intervals:

Weekly / 100-200 miles (160-321 km)
