Inspecting your Electric Bike

Inspect your e-bike before each ride to ensure safety features are operational. Listen for changes in sounds, as these can indicate mechanical or power issues.

Holding the Handlebars

Place fingers over brake levers and wrap palms and thumbs around grips for easy brake activation in emergencies.

Turning your E-bike On and Off

Press and hold the round button in the middle of the keypad on the left handlebar to turn the e-bike on or off.

Accelerating and Decelerating

The throttle is on the right handlebar grip. Rotate the grip counterclockwise to accelerate and release (turn away) to decelerate. Avoid over-rotating the throttle to prevent damage.

Warning: Do not activate the accelerator until seated and ready. The e-bike can escape control, causing injury or damage.

Stopping

The e-bike has front and rear brakes, activated by levers on the handlebars. Pull levers towards you. Using both brakes stops faster; one brake provides a gentler stop. Power to the motor automatically turns off when brakes are activated.

Safety Tips for Braking

• Wet weather reduces brake efficiency due to reduced friction. Slow down and allow more stopping room.
• Have brakes and pads checked regularly; pads wear down and need replacement.
• Engage the rear brake before the front brake to avoid flipping.

Signalling

Use appropriate hand signals when riding.

Lights

Headlight and tail light improve safety in dark conditions. They consume electricity, potentially reducing range by about 5%.

Pedaling

The e-bike is motor-assisted. Pedaling with the motor increases travel distance and reduces battery draw.

Riding in Wet Weather

The e-bike is designed for wet conditions, but the rear motor can cause slips at high speeds. Avoid high speeds in wet weather. Brakes may be less effective due to reduced friction.

The Motor and Water

Do not immerse the e-bike in water. Ensure water level stays below the middle of the tire to prevent water ingress into the motor, which can cause short-circuits and damage.

Riding in Cold Weather

The e-bike operates year-round, but cold conditions (below 10°C) reduce battery performance for both Lithium-Ion and Lead-Acid types. Cold weather may also necessitate earlier battery replacement.

Maximum Load

Do not exceed the maximum load capacity specified in the technical specifications. Exceeding it degrades performance, can damage components (shocks, mechanism, frame), and may cause motor burnout.

Disconnecting the Circuit Breaker

Disconnecting the circuit breaker blocks battery power. This is useful for storage or servicing. Note: The alarm system requires the circuit breaker to be on. Do not leave it 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 and secure the bike. Refer to "The Battery" section for battery maintenance during storage.

The Battery

This section details the battery powering your e-bike. Treat electrical systems with respect.

Battery Power

The dashboard has a battery charge indicator. When activated, the gauge shows available power. Recharge if the power has dropped significantly.

Distance and Power

The battery offers a range of 35+ km per charge. Actual range depends on rider weight, wind resistance, riding habits, terrain (hills), and tire pressure.

Saving Power

To save electricity on long distances:

• Coasting: Utilize momentum downhill or on flat surfaces without drawing power.
• Stopping and Starting: Avoid frequent stop-and-go; starting from a stop draws more power.
• Weight: Remove unnecessary weight.
• Air Pressure: Ensure proper tire pressure to reduce drag and increase efficiency.
• Head and Tail Lights: Turn off lights to conserve power if safe; they reduce range by about 5%.
• Pedalling: Pedal when accelerating from a stop to assist the motor.

Charging your E-Bike

You need the supplied charger and a 110V household electrical outlet.

Charger Warning

Only use supplied chargers. Using incompatible chargers can irreparably damage the battery and electrical systems, and may cause injury.

Charging Steps:

1. Turn off the e-bike.
2. Plug the female end of the charger cable into the e-bike's charging slot.
3. Plug the male end of the charger power cable into a 110V wall socket or a compatible portable generator.
4. Allow the battery to charge for the appropriate time.
5. Disconnect the charger when the LED light turns green, indicating the battery is fully charged.

If the LED stays red for over 6 hours and the battery becomes very hot, the battery or charger may need replacement. Stop charging and contact a Daymak dealer immediately.

Understanding your Voltage

Voltage indicates the unit's power. As voltage drops, performance decreases. The Low Voltage Threshold protects the battery by preventing the motor from drawing power below a certain point, extending battery life.

If the motor cuts off or fails to engage, voltage may be below the threshold and require charging. Voltage thresholds can be checked via a Bluetooth app (if applicable) or using the provided chart.

Voltage Chart

LITHIUM Full/Low Voltage Reading: The exact low voltage and full charge readings for lithium batteries depend on their composition. The numbers followed by "S" indicate the number of series in the battery pack. Contact your local Daymak dealer for exact series information.

Technical Data

The Motor and Wheel Assembly

The Max S uses a magnetic DC brushless motor in the rear wheel hub, offering good low-end torque and efficiency. It is quiet but produces some noise. The rear hub also contains speed reduction gears and a speed free clutch.

The Freewheel

Wheels have freewheels, meaning the drivetrain is not fixed. This allows coasting or turning off the engine downhill without slowing, enabling higher speeds and power conservation.

The Controller

Daymak Drive technology, developed by Daymak, controls e-bike components, enabling faster acceleration, better hill climbing, and energy saving.

The Brakes

Hydraulic disc brakes provide fine stopping and control. They require periodic servicing and tension adjustment. Brake activation increases tension, engaging clamps for effective stopping.

The Chain and Pedals

Pedals connect to the rear wheel via the chain, forming a human-powered drivetrain. Pedals are not removable.

Vehicle Identification Number (VIN)

Your unit has a VIN, which should be recorded for theft protection and warranty registration on Daymak.com. The VIN is located on the front of the bike, under the Daymak logo.

Maintenance and Troubleshooting

This section addresses common problems and solutions. Many parts are not user-serviceable; alterations void the warranty. Contact a Daymak dealer for repairs on electrical or mechanical components.

Tire Pressure

Maintain proper tire pressure as indicated on the tire sidewall. Low pressure reduces performance and increases damage risk. Cold weather lowers pressure; warm weather increases it.

Procedure:

1. Identify required pressure on the tire sidewall.
2. Locate the air valve.
3. Remove and secure the valve cap.
4. Place pump nozzle over the valve.
5. Inflate carefully, avoiding over-pressurization.
6. Remove pump nozzle, minimizing air loss.
7. Replace the valve cap.

Proper pressure improves range by reducing motor workload.

Replacing Flat Tires

Replacing flat tubes on e-bikes is more complex than on regular bicycles, requiring specific tools, skill, and patience. The front wheel is easier to service. The rear wheel is connected to the hub motor and other parts; attempting replacement without expertise may cause serious problems. Contact your Daymak dealer for safe wheel/tire removal and tube replacement procedures, or have them perform the service.

The Motor

Do not service the motor yourself. Bring the e-bike to your Daymak dealer. Motor repair requires significant expertise. Maintenance is suggested every 100 running hours.

The Chain

Ensure the chain is well-oiled and lubricated for optimal function. Regular maintenance is crucial.

Bringing in your E-bike for Service

Do not service electronic or mechanical parts unless you are certain of your actions and possess electrical/mechanical knowledge. If the e-bike malfunctions, disconnect the circuit breaker and take it to your local Daymak dealer.

Liability
