Riding Instructions

This guide assumes you know how to ride a standard bicycle. If you do not have cycling experience, an e-bike is too dangerous to ride. Do not begin learning to ride a bicycle using an e-bike.

Important Notes

• Ebikes are Fast! E-bikes travel at higher speeds than many riders are accustomed to. Use caution, especially in mixed traffic. 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.
• 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. Let faster vehicles overtake you and give ample room for slower vehicles.

Items to Carry with the Electric Bike

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

Inspecting your Electric Bike

Always inspect your e-bike before riding to ensure safety features are operating properly. Many accidents can be avoided with routine inspections. Listen for changes in sounds your e-bike makes, as mechanical or power issues can affect them.

Holding the Handlebars

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

Turning your E-bike On and Off

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

Accelerating and Decelerating

The throttle ? is on the right-hand grip. Rotate the grip counterclockwise (away from you) to accelerate. Release the grip (turn it towards you) to decelerate. Do not over-rotate the accelerator, as this could damage the battery and electrical components.

Warning: Do not activate the accelerator until you are seated on the bicycle and ready to accelerate. The e-bike can easily escape 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 activate them. Using both brakes stops you more quickly; using one brake allows for a gentle stop. When brakes ? are activated, power to the motor is automatically turned off until you release the brakes, allowing for safe stopping.

Safety Tips for Stopping

• In wet weather, water can reduce brake efficiency due to less friction between brake pads and wheels. Slow down and allow more stopping room.
• Have your brakes and brake pads checked regularly. Brake pads wear down and require replacement after significant use.
• Engage the rear brakes first before the front brakes to avoid flipping the unit.

Signalling and Lights

The Horn ?

The e-bike has a horn. The horn button is on the left handlebar. Simply press it to activate the horn.

Turn Signal Lights ➡️⬅️

Your e-bike has turn signal lights. The activator is on the left handlebar. Push it left or right to indicate turning. Press it to the middle to cancel the signal.

Lights ?

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

Pedaling

This e-bike is designed for motor-assisted pedaling. Using the motor alone is possible, but pedaling with the motor increases travel distance by assisting the motor and reducing battery draw.

Riding in Wet or Cold Weather

Riding in Wet Weather

Your e-bike is designed for wet conditions, but the motor on the rear wheel can cause slips at high speeds. Avoid high speeds in very wet conditions. Water can also reduce brake effectiveness.

The Motor and Water

Your e-bike is not designed to be immersed in water. Ensure water levels do not go above 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 is designed for year-round operation. However, in very cold conditions (below 10°C), motor performance and brake effectiveness can be reduced. Batteries (Lithium-Ion and Lead-Acid) experience reduced performance in cold temperatures. Riding in cold may require earlier battery replacement.

Maximum Load

Do not exceed the maximum load capabilities listed in the technical specifications. Exceeding the maximum load can reduce performance, damage shocks, mechanisms, or the frame, and potentially cause the motor to burn out.

Disconnecting the Circuit Breaker

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

Long-Term Storage of your E-bike

If storing for a long period, disconnect the circuit breaker to prevent accidental activation. Refer to "The Battery" section for battery maintenance during storage.

The Battery

Treat your e-bike's electrical systems with respect. The dashboard has a battery charge indicator ?.

Battery Power

The battery charge indicator on the dashboard shows available power. If power has dropped significantly, recharge your e-bike.

Distance and Power

Your battery can provide a range of 35+ km per charge. Range depends on rider weight, wind resistance, driving habits, hills, and tire pressure.

Saving Power

To save electricity on long distances:

• Coasting: Use momentum downhill or on flat surfaces without drawing motor power.
• Stopping and Starting: Avoid frequent stop-and-go movements, as the motor draws more power when starting from a stop.
• Weight: Remove unnecessary weight from the bike.
• 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 safe to do so (reduces range by ~5%).
• Pedaling: Pedal to assist acceleration from a full stop.

Understanding Your Voltage

Electric scooter power is displayed as voltage. Lower voltage indicates reduced performance. The voltage level, battery type (Lithium vs. Lead Acid), and battery composition affect the range between full charge and the low voltage threshold.

Low Voltage Threshold

Your unit protects the battery by preventing the motor from drawing power below the Low Voltage Threshold, increasing the unit's life expectancy. If the motor starts cutting off or not engaging, the voltage may be dropping past the threshold and the unit needs charging.

Voltage Chart

Lithium batteries have varying full/low voltage readings based on composition and series count. Contact your local Daymak dealer for exact series information.

Charging your E-Bike

You will need the charger supplied with your e-bike and a 110V household electrical outlet.

Charger Warning

Only use chargers with identical specifications to the original. Using incorrect chargers can 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 a 110V wall socket or a portable generator providing 110V current.
4. Allow the battery to charge for 6-12 hours.
5. Disconnect the charger when the LED light turns green ✅. The batteries are fully charged.

If the charger's LED status light remains red ? for over 14 hours and the battery is very hot, the battery or charger may need replacement. Stop charging and bring both to your Daymak dealer immediately. Do not charge the battery.

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.

The charger will glow red ? while charging and green ? when fully charged.

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

Accessing your Circuit Breaker

To prevent surges, a circuit breaker is installed. If you have no power, the circuit breaker may have been triggered. To access it, look under the seat by unlocking the seat lock ?.

Battery Care

Follow these suggestions for optimal battery performance:

• Charge it: Charge your battery immediately after riding.
• Full Charge: Do not let the battery run down completely before storage. This reduces lifespan and can cause damage.
• Keep it Charged: When stored, charge the battery occasionally (e.g., once every 21 days) to maintain its power supply.
• Storage Conditions: Store the battery on a flat, cool, dry surface. Avoid temperatures below 10°C for extended periods.

Warning: DO NOT place your Lead-Acid battery on concrete. Concrete drains battery power and neutralizes lead-acid, potentially causing the battery to lose its ability to store electricity.

Cold Weather and your Battery

Below 10°C, battery performance is reduced for both Lithium-Ion and Lead-Acid batteries. Riding in cold temperatures may necessitate earlier battery replacement.

Replacement and Disposal

Lead-acid batteries typically need replacement after ~300 charges; Lithium-ion batteries after ~1000 charges. Reduced charge capacity indicates replacement is needed. Contact your local Daymak dealer for new batteries. Dispose of old batteries at a proper municipal battery recycling facility or contact your Daymak dealer.
