Important Notes

• Ebikes are Fast! E-bikes can travel at higher speeds than many bicycle riders are accustomed to. Use caution at all times, especially in mixed traffic. Always consider driving and traveling conditions.
• Obey the Law. Follow all provincial and city traffic laws, including obeying stop signs, checking carefully when turning, and riding defensively. An e-bike is a motorized vehicle and must be operated according to the law.
• Stay Sober. Never ride your bicycle while intoxicated. An e-bike is capable of traveling faster than a normal bicycle, and you must always be in control.
• Share the Road. Be careful in mixed traffic. Allow vehicles faster than you to overtake, and give ample room for vehicles traveling slower.

Items to Carry with the Electric Bike

It is advisable to carry the following items when riding your e-bike:

• The charger, to charge the bike if the battery power runs out.
• 30 Amp Fuse, as spares for the batteries, in case the fuses blow (if applicable).
• A lock, to secure your e-bike when parked.
• A helmet, as required by safety laws.

Inspecting your Electric Bike

Always inspect your e-bike before riding to ensure its safety features are operating properly. Many accidents can be avoided with routine inspections. Pay attention to small changes in the bike's feel or sounds, as these may indicate mechanical or power issues.

Holding the Handlebars

Place your fingers over the brake levers, using your palms and thumbs to wrap around the handlegrips. This allows for easy activation of the brakes by squeezing your hand, enabling quick stops.

Turning your E-bike On and Off

To turn on your e-bike, insert the key into the ignition, located below the dashboard, and turn the key to the right. The power indicator will light up, and the battery charge indicator will show the available power. To turn off the e-bike, turn the key to the left and remove it.

Warning: When the e-bike is activated, the electrical system becomes live. Do not attempt to make changes to the e-bike (such as removing the battery or repairing electrical components) while it is activated. Turn the e-bike off and remove the key before accessing any electrical components. The battery carries a significant electric charge and must be treated with respect.

Accelerating and Decelerating

The throttle is located on the right-side hand grip. Rotate the grip counterclockwise (away from you) to accelerate. To decelerate, release the grip (turn it towards you). Avoid over-rotating the accelerator, as this could damage the throttle and electrical components.

Warning: Do not activate the accelerator until you are seated on the bicycle and are ready to accelerate. The e-bike can easily escape your control, potentially causing injury or damage.

Stopping

Your e-bike has two sets of brakes, front and rear. The levers on the handlebars activate the brakes. Pull the levers toward you to engage them. You can use both brakes for a quicker stop or one brake for a gentler stop. When the brakes are activated, the motor power is automatically turned off until the brakes are released, ensuring safe stopping.

Safety Tips (Brakes)

• When traveling in wet weather, water can reduce brake efficiency due to decreased friction. Slow down and allow more stopping distance.
• It is advisable to have your brakes and brake pads checked regularly, as brake pads wear down over time and require replacement.
• Engage the rear brakes first before the front brakes to avoid flipping the unit.

Operation and Features

Signalling

The Horn: The horn button is located on the left handlebar. Press it to activate the horn.

Turn Signal Lights: The turn signal activator is on the left handlebar. Push it left or right to indicate your turning direction. Push it to the middle to cancel the signal.

Lights

The headlight and tail light improve safety at night or in dark areas. They consume electricity, potentially reducing the maximum travel distance by approximately 5% per charge.

Pedaling

This e-bike is designed for motor assistance. While the motor can be used alone, pedaling in conjunction with the motor increases travel distance and reduces battery draw.

Riding in Wet Weather

Your e-bike is designed to function in wet conditions. However, the motor on the rear wheel can cause slips at high speeds. Avoid high speeds in wet conditions. Water can also reduce brake effectiveness. Slow down and allow more stopping distance.

The Motor and Water

The e-bike is not designed for immersion in water. Ensure water levels do not exceed the middle of the tire to prevent water from entering the motor, which can cause short-circuits and damage electrical systems.

Riding in Cold Weather

The e-bike operates year-round. In very cold conditions or with snow/slush, the motor may get wet, and brakes may function less effectively. Below 10 degrees Celsius, battery performance is reduced (Lithium-Ion batteries perform better than Lead-Acid in temperature extremes, but both are affected). Riding in cold temperatures may require earlier battery replacement.

Maximum Load

Do not exceed the e-bike's maximum load capacity, as listed in the technical specifications. Exceeding the maximum load can reduce performance, damage components like shocks and the frame, or cause the motor to overheat.

Disconnecting the Circuit Breaker

Disconnecting the circuit breaker blocks all power from the battery. This is useful for storage or servicing. Note: The alarm system requires the circuit breaker to be ON. Do not leave the circuit breaker off in an unsafe location if concerned about theft.

Long-Term Storage of your E-bike

For long-term storage, disconnect the circuit breaker to prevent accidental activation. Refer to "The Battery" section for battery maintenance during storage.

The Battery

This section details information about the battery powering your e-bike. Always treat the electrical systems with respect.

Battery Power

The dashboard features a battery charge indicator. When the e-bike is activated, the gauge displays the available battery power. Charge the e-bike if the power has dropped significantly.

Distance and Power

Your battery has a capacity to travel over 35 km on a single charge. The actual range depends on variables such as rider weight, wind resistance, riding habits, terrain (hills), and tire pressure.

Saving Power

To conserve electricity on long distances, adopt better driving habits:

• Coasting: Utilize momentum when going downhill or on flat surfaces without drawing power from the motor.
• Stopping and Starting: Avoid frequent stop-and-go movements, as the motor draws more power when starting from a standstill.
• Weight: Remove unnecessary weight from the bike to reduce motor power draw.
• Air Pressure: Ensure tires have proper air pressure to reduce drag and increase efficiency.
• Head and Tail Lights: Turn off lights to conserve power if it is safe to do so (may reduce range by about 5%).
• Pedalling: Assist acceleration from a full stop by pedaling.

Understanding Your Voltage

Electric scooters display primary power as voltage. This indicates the unit's power level, which drops as performance is limited. The range between a full charge and the low voltage threshold varies based on voltage and battery type (Lithium vs. Lead Acid).

Low Voltage Threshold

The unit protects the battery by preventing the motor from drawing power below the Low Voltage Threshold, significantly increasing the unit's life expectancy. If the motor starts cutting off or fails to engage, it may be due to the voltage dropping below this threshold, indicating a need for charging.

Voltage Chart

The chart (not displayed here) shows Lithium Full/Low Voltage Readings, with numbers and "S" representing series in the battery pack. Contact your local Daymak dealer to know the exact series of your battery.

Charging Your E-Bike

Charging Process

To charge your e-bike, you will need the charger supplied with your e-bike and a 110V household electrical outlet.

Charger Warning: Only use chargers supplied with your e-bike. Using chargers with different specifications could irreparably damage the battery and electrical systems, and may cause injury.

Charging Steps:

1. Turn off the e-bike and remove the key from the ignition.
2. Plug the female end of the charger cable into the charging slot on the e-bike.
3. Plug the male end of the charger power cable into your wall socket (a 110V household electricity supply) or a portable generator providing 110V current.
4. Allow the e-bike's battery to charge for the appropriate amount of time, typically 6-12 hours.
5. Disconnect the charger when the LED light on the charger turns green, indicating the batteries are fully charged.

If the charger's LED status light does not change from red to green after an extended period (e.g., more than 14 hours) and the battery is very hot, the battery or charger may need replacing. Stop charging and contact your Daymak dealer immediately. Do not attempt to charge the battery further.

Charging the Berlin

The Berlin comes with either a lead-acid or Lithium Ion battery pack. To charge the Berlin directly, locate the charge port on the center column where you sit. Lift the protective flap and plug in the female end of the charger cable. The charger will glow red while charging and turn green when the unit is fully charged.

Warning: Do not leave the Berlin charging for extended periods after it is fully charged. Unplug the charger as soon as the bike is charged.

Accessing your Circuit Breaker

A circuit breaker is installed to prevent surges. If you are unable to get power to your bike, the circuit breaker may have been triggered and needs to be switched to the ON position. Access it under the seat by using the seat lock.

Battery Care

Follow these suggestions to maintain your battery's optimal performance and lifespan:

• Charge it: Charge your battery immediately after riding.
• Full Charge: Do not allow the battery to run down completely and then sit in storage without a charge, as this significantly reduces its lifespan and may cause damage.
• Keep it Charged: When storing the bike, charge the battery occasionally to ensure its power supply does not deplete. Charging it once every 21 days should be sufficient.
• Storage Conditions: Store the battery on a flat, cool, dry surface. Avoid letting the battery temperature drop below 10 degrees Celsius for extended periods.

Cold Weather and your Battery

Below 10 degrees Celsius, battery performance is reduced. While Lithium-Ion batteries perform better than Lead-Acid batteries in temperature extremes, both will experience reduced performance in cold temperatures. Repeatedly riding the e-bike in cold temperatures may also cause your battery to need replacement sooner.

Replacement and Disposal

A lead-acid battery typically needs replacement after approximately 300 charges, while a lithium-ion battery lasts for about 1000 charges. When the battery needs replacement, you will notice a reduced charge capacity. Contact your local Daymak dealer to purchase a new battery. Dispose of old batteries at a proper municipal battery recycling facility or contact your local Daymak dealer if none is available.

The Berlin comes with a rear storage trunk that can be securely locked. To access it, remove the security clips on either side of the trunk, insert the trunk key, and turn it to open the case.

Technical Data

The Motor and Wheel Assembly

The Berlin is equipped with a 500 Watt magnetic DC brushless motor on the rear wheel hub, providing excellent low-end torque and high efficiency within its operating range. While quiet, the motor does produce some noise. The rear hub also houses the speed reduction gear and the speed free clutch.

The Freewheel

The wheels have freewheels, meaning the drive train is not fixedly geared. This allows you to turn off the engine when coasting or traveling downhill, enabling the e-bike to continue moving without slowing. This feature allows for faster coasting speeds and conserves electrical power by allowing the motor to rest.

The Controller

Daymak pioneered intelligent component control in e-bikes with its Daymak Drive technology, which acts as the brain of your e-bike. This technology enables faster acceleration, improved hill climbing, and energy saving. The electronic controller is located under the seat assembly and efficiently regulates the speed and electronic functions. It supports stepless speed adjustment, motor shut-off when brakes are activated, low voltage protection, and fuses to prevent system damage. Control may also be available via a Bluetooth app.

The Brakes

The e-bike's brakes are disc-brakes, similar to those found on gas scooters and motorcycles, offering fine stopping power and control. This is a well-tested technology, but the brakes will require periodic servicing and tension adjustments. Unlike traditional friction-grip bicycle brakes that clamp from the outside, drum brakes clamp from the inside. When brakes are activated, tension increases, engaging the clamps, which is an effective stopping method.

Vehicle Identification Number (VIN)

Your unit comes with a Vehicle Identification Number (VIN). It is important to write this down and keep it in a safe place in case of theft. The VIN is also required for registering your warranty on the Daymak.com website. To find the VIN on your Berlin, look on the center steering column. You will find a plastic cover marked "VIN"; pry this off with a flat screwdriver or similar item to reveal the VIN.

Maintenance and Troubleshooting

This section outlines potential problems and solutions. Many parts are not user-serviceable and require repair by trained professionals, especially electrical and mechanical components. Altering these components voids the warranty.

Tire Pressure

Maintain the correct air pressure in your tires. Low air pressure reduces performance and makes the e-bike more susceptible to damage. Cold weather lowers tire pressure, while warmer weather increases it, even without leaks. To refill tires:

1. Identify the required pressure on the tire rim sidewall.
2. Locate the air valve on the inner surface of the tire rim.
3. Remove the valve cap and store it securely.
4. Place the nozzle end of an air pump over the valve.
5. Pump air into the tire, ensuring not to exceed the recommended pressure.
6. Remove the pump nozzle carefully to minimize air loss.
7. Replace the valve cap.

Maintaining proper tire pressure allows for greater travel distance on a single charge, as the motor works less.

Replacing Flat Tires

Replacing flat tire tubes on e-bikes is more complex than on regular bicycles, requiring proper tools, skill, and patience. The front wheel is easier to service than the rear wheel, which is connected to the hub motor and other mechanical parts. Attempting to change a flat rear tire without expertise may cause serious problems. Contact your Daymak dealer for specific instructions on wheel and tire removal, or for assistance with tube replacement.

The Motor

Do not attempt to service the motor yourself. Bring the e-bike to your Daymak dealer. The motor is a complex, fine-tuned mechanism requiring significant expertise for repair. Maintenance is suggested approximately every 100 running hours.

The Chain

Ensure the chain is well-oiled and lubricated. It is an important component that requires maintenance for proper function.

Shock Absorbers and Comfort

If your riding experience feels unusually bumpy, first check the air pressure in your tires. Low tire pressure can affect comfort and may be mistaken for shock absorber issues. If the problem persists, take your e-bike to your Daymak dealer for servicing.

Bringing in your E-bike for Service

Do not attempt to service electronic or mechanical parts unless you are certain of your actions and possess a solid understanding of electrical and mechanical equipment. If your e-bike is not performing correctly, disconnect the circuit breaker and bring it to your local Daymak dealer. Do not store the e-bike without disconnecting the circuit breaker.

Daymak will not be held responsible for damage or injuries resulting from errors due to improperly serviced parts.

Ebike Maintenance

Cleaning

Regular cleaning is crucial for your e-bike's longevity, saving you money and time on repairs. Clean your e-bike weekly.

• Avoid aggressive power jets or water sprays when washing the e-bike, and keep water away from the battery as much as possible.
• Clean gently but thoroughly, ensuring all outer casings of electric parts are dry and clean.
• Remove any dirt, debris, sand, mud, grit, or grime caught on the bike and dry it off.
• While cleaning, inspect for worn, loose, cracked, rusted, torn, or damaged parts. Buckled paint can also indicate parts needing closer inspection.

Lubricating

It is recommended to lubricate the chain, levers, derailleur, and cables. A clean, lubricated e-bike tends to be faster, smoother, and quieter. Apply lubricant to parts, let it sit for a few minutes, then wipe off excess with a rag. Periodically clean parts with a degreaser to remove collected dirt.

Weather Considerations

• Do not leave the bike out in the rain or snow. Store it in a dry place, out of direct sunlight, as overheating batteries can cause problems.
• Do not open casings or chargers, as they are difficult to reseal effectively, making them more susceptible to water damage and extreme weather conditions.
• Batteries should be removed from the e-bike if not used and charged once a month, regardless of usage.

Maintenance Schedule

The frequency of maintenance depends on usage and conditions. Recreational riders require less maintenance than off-road riders. The harder you ride, the more care your bike needs to last. Maintenance intervals are as follows:
