General information

Security & Warranty

Warranty
The standard warranty is covered by the attached Terms and Conditions. It expires in the event of damage caused by actions that contradict these operating instructions.

Usage
Black Tea Motorbikes motorcycles have been homologated to the highest standards for road use by TÜV Süd in Munich. It is therefore prohibited to remove any equipment or tamper with the wiring outside of an authorized service center. The Bonfire is not designed for off-road use or racing. Important: Although the Bonfire has a fuel cap, the tank is not intended to be filled with any type of liquid. In particular, please do not fill the tank with gasoline. The Bonfire is an
all-electric motorcycle.

Driving
When you ride the Bonfire for the first time, there are a few things to keep in mind. The bike has an electric motor with instant torque and a primary drive without gears, which means that you have all the power available at all times through the throttle. It is very sensitive and it is highly recommended to ride in the first driving mode to get used to this type of vehicle.
Important: You have two keys. The larger key is for the ignition and steering wheel lock. The small key is for the battery box. Be sure to use the correct key, otherwise you can damage the lock or the key. There is no clutch; instead, the rear brake is located on the left side of the handlebar. This can feel very unnatural for experienced combustion motorcyclists. Remember that electric vehicles are quiet. Be aware of people or other cyclists who may be near the lanes you are using.

• Never drive under the influence of alcohol or drugs
•  Always check local laws and regulations where you plan to drive

During the ride

Brakes
Please note that unlike a normal gasoline motorcycle, both the rear and front brakes are on the handlebars and there is no foot brake. The combined rear and front brakes are on the left side of the handlebars and the front brake is on the right side of the handlebars.

Driving mode switch
You can change the driving mode with the 1,2,3 key. There are 3 different performance modes to choose from when driving. Never ride beyond your comfort level and always ride according to your personal riding abilities. We always recommend new riders start with the first mode to get used to the bike and the differences between an electric and internal combustion engine. The 3 different power modes have different characteristics in terms of top speed, acceleration and torque to suit riders of all levels, from beginners to professionals.

• Power mode 1 – Eco
  This mode is always recommended when you ride a Bonfire for the first time. It has a limited top speed of 35 km/h and smooth acceleration.

• Power mode 2 – Normal
  With a top speed of 40 km/h and good acceleration, this mode is perfect for slow roads or passages.

• Performance mode 3 – Sport
  There are no power restrictions here. This mode is perfect when you need all the power available. 45 km/h top speed and a good acceleration.

• Regenerative braking
  When the throttle is released, your bike starts regenerative braking. This allows the bike to stop without using the brakes and recharges the battery.
  Important: Regenerative braking can be unreliable, especially when the battery is fully charged. Therefore, always use the regenerative braking function with  caution.

Good to know

Side stand
The side stand can be conveniently folded out even when you are sitting on your bike and activates a switch that cuts the power to the motor for safety reasons. As long as the side stand is folded out, the bike does not move.

Mirror
You can easily adjust the alignment of the mirrors. The joint works with a counter-rotating screw system. Place the mirrors in the thread on the handlebars & turn them clockwise. Align the mirrors and then tighten the nut.

Display
On the display you can read the SOC (state of charge), your riding mode, speed, odometer and time.
Important: It’s best to check out our “Battery 101” for more information regarding reading the display.

Display operation
The lower left key is the selection key and the upper left key is the setting key. Clear odometer With the display on, simply hold down the settings button for 3 seconds. This will clear the trip meter.

Emergency operation

Battery under voltage
If the voltage is outside the normal range of the battery, e.g. in the case of an empty battery, the power is restricted so as not to damage the battery or other components of the drive train. The controller outputs the following error code (under voltage): ¤ ¤¤¤¤

Overheating of the controller
If the controller gets too hot, performance is gradually reduced. When the temperature reaches 100 °C, the bike will stop running until the temperature drops below 80 °C. It is best to take a short break to allow the controller to cool down. The controller outputs the following error code: ¤¤ ¤¤¤.

Motor overtemperature
When the engine gets too hot, the power is gradually reduced. When the temperature reaches 150°C, the bike stops running until the temperature drops below 130°C. It is best to take a short break to allow the engine to cool down. The controller issues the following error code: ¤¤¤¤ ¤¤¤

Battery overtemperature and battery under temperature
The battery does not tolerate extremely warm or cold temperatures. To avoid damage to the battery, it is recommended to leave the bike inside when the outside temperature is below 2°C or above 35°C.

•  Check if the axle of the rear wheel is adjusted correctly.

Brakes

Inspect the front and rear brake calipers to make sure they or the brake mounts are not damaged. Check the front and rear brake pads to make sure they are not worn. Look through the window into the brake fluid reservoir to see if there is enough brake fluid left. Do a brake test to make sure the front and rear brakes are working properly.

Removing and charging the r battery

Removing the battery

For safety reasons, you cannot ride the bike while charging. Make sure the bike is secure before removing the battery. Use your key to open the battery box. If your bike is on a level surface, the door should remain open. Please turn off the battery. You will find the on/off switch on top of the battery. Now disconnect the battery from the bike. Slide the fuse of the battery upwards. Use the handle of the battery to take it out of the bike.
Important: Always be careful when handling the battery. If it is dropped, visually inspect it and contact a Black Tea Motorbikes representative if it is damaged.

Charging de r Battery

Plug the charger into the wall socket and then connect the battery. You should be able to hear the charger while it is charging. The charger light will change from green to red when the battery is connected. When the battery is finished charging, the light will turn green.
Important: It’s best to check out our “Battery 101” for more information.

Reinstalling the battery

Make sure that the battery switch is in the “OFF” position. Now put the battery back into the bike. Connect it. Slide the fuse down and turn the battery on. Close and lock the battery box. Make sure that there is no dirt on the floor. This can damage the battery and block the closing of the door.
Note: Don’t worry if you ever forget to disconnect the battery and the plugs spark on contact. This is fine, but can wear out the plug over time.

Ownership and operation

 Maintenance and Cleaning

It is important to keep your Bonfire in good condition to prolong its life. Clean the bike after riding and follow the “Regular Inspection” checklist. Charge the bike to a state of charge of at least 30%. Switch off the bike and the battery if it is not used for more than one week. Otherwise, it will be in standby mode and discharge the battery to an unhealthy level, shortening battery life. You must always be careful when cleaning the Bonfire. The electrical components of the bike can be damaged if not cleaned properly. Make sure the motorcycle is stationary and turned off before washing. Never use a pressure washer or a water hose to clean the motorcycle. It is recommended to use compressed air and a bucket of water together with a cloth and a brush.

Storage

Follow these steps to ensure that your Bonfire is always in good condition and to extend the life of the motorcycle. We recommend that you ride the bike at least once a month, as some components of the bike need to be used to keep them in the best condition. Store the bike in a closed space and protect it from sunlight to avoid unnecessary aging or discoloration. Make sure your Bonfire is completely turned off by disconnecting the battery. Never store your Bonfire with an empty battery. If the bike is stored for an extended period of time, charge it to at least 50% to extend the life of the battery. Never store your Bonfire below 10° C. If you cannot store the motorcycle at higher temperatures, remove the battery and bring it to your home.
Important: It’s best to check out our “Battery 101” for more information regarding battery storage.

 Interlock

It is recommended to use an additional external lock, which is recommended for motorcycles. When you park your Bonfire on the road, always turn it off, remove the batteries, lock your handlebars and take your key with you. The steering lock is located under the triple clamp between the forks. Lock the steering lock by turning the handlebars all the way to the left, inserting the key into the steering lock on the right side and turning the key. You will feel the handlebars lock in this position, preventing you from riding your Bonfire.
Caution: Note that the key is fragile and turning the steering while the key is in the lock may damage the mechanism and/or the key.

Accident

In the event of an accident, please inspect your Bonfire for visual or structural damage. If you notice damage that affects the handling of the vehicle, stop driving to avoid further damage to the vehicle, yourself, or the surrounding area. If your Bonfire needs repair, please contact us at [email protected]. To check, please go through the procedures in Chapter 3 “Periodic Inspection and Maintenance”. In case of a broken or damaged part, visit www.blackteamotorbikes.com to order replacement parts. If you cannot find what you need or have any questions, please contact Black Tea Motorbikes directly.

Troubleshooting

If your motorcycle is not working properly, please read through the following use cases to find a solution. If you can’t find your problem or a working solution, contact Black Tea Motorbikes directly. My motorcycle does not turn on First check if the battery, ignition lock and kill switch are properly turned on. Open the
battery box to check that the battery is properly connected to the motorcycle. Make sure that the side stand is up. If your motorcycle still does not turn on, your ignition switch may be defective. Please contact our customer service. My motorcycle does not give full power The motorcycle protects itself and may limit performance under certain circumstances. This happens when one of the components of the drivetrain is overheated, under- or over tensioned, etc. First, make sure the motorcycle is properly charged by checking the gauge. When the battery is almost empty, the battery cells inside lose the ability to achieve a high discharge (full power). Please be careful when checking if the controller or the engine are overheated, as you can easily get burned. Please allow the vehicle to cool down sufficiently to avoid permanent damage to the engine, controller or battery. My engine makes strange noises or does not turn over If the engine makes strange noises when you step on the gas and does not run properly, please turn off the motorcycle and do not step on the gas, as the engine can still overheat
from the battery current. This could happen if the sensors in the engine get wet. The problem is temporary, please put the motorcycle indoors for 24 hours to dry.
My motorcycle does not turn on after a long period of inactivity Turn on the main switch of the battery and measure the voltage with a multimeter. If the voltage is below 43 V, please charge your battery.

 Tools

To properly maintain your Bonfire and keep it in good condition, we recommend that you always use quality tools and treat the motorcycle with care. If you are unable or unwilling to perform maintenance yourself, please contact someone who has the appropriate experience. For the Bonfire, Black Tea Motorbikes recommends the purchase and use of the following tools.

• Hexagon wrench set, 1-10 mm
• Screwdriver
•  Rubber mallet
• Wrench set 8 – 24 mm
