IoT
Why can't I unlock my bike?
To unlock the bike, the main battery must be correctly installed. Without the battery, the motor cannot receive power, and therefore the bike cannot be unlocked.
Please also note that the battery cannot be charged at temperatures around freezing point – this can affect both unlocking and operation.
How do I install an IoT device on my bike?
Our IoT devices are installed as standard at the factory during production. If you already have a bike in use, the device can also be retrofitted at an authorized dealer.
To ensure proper installation and high quality, an IoT device should always be installed by a dealer.
How do I keep my IoT device up to date?
Updates with new features and services are automatically installed via wireless updates (OTA).
You will receive regular push notifications in the app when new features are available, allowing you to easily improve and upgrade your bike—without ever leaving home.
Where in the world does the tracker work?
Comodules Connectivity Solution tracks your e-bike via satellite positioning, 4G networks, and—where coverage is limited—2G as well. This means you can locate your bike globally, whether you are in Copenhagen or New York.
Unlike Bluetooth® trackers, which only work over short distances, Comodule's technology provides global coverage and increases the chance of getting your e-bike back if it is stolen.
How long can I track my bike if it gets stolen?
The device is automatically powered by the bike's main battery and has very low energy consumption.
If the bike is stolen, the tracker will continue to charge as long as the main battery is in the bike and is charged.
If the main battery is removed or runs out of power, the tracker can continue to operate on its own backup battery:
- Up to4 weeks if the bike is stationary.
- Up to1 week if the bike is in constant motion.
Note: This functionality only applies to the integrated IoT device.
How does the IoT device work?
The IoT solution consists of three elements: an IoT device, Christiania Bikes , and a connection subscription.
The device is either integrated directly at the factory or retrofitted at the dealer. When you receive your bike, download the app to your phone and connect to the bike via Bluetooth.
When you connect for the first time, a unique code is automatically created between the IoT device and the motor system. This code ensures that the bike can only be unlocked via the app or through our support service.
In the app, you can activate your subscription, which gives you access to tracking and other anti-theft features. When your subscription period expires, you can easily renew it directly in the app.
Designed in collaboration with Comodule
In collaboration with Comodule, we have developed an IoT device that is tailor-made for our bikes. It ensures optimal signal reception, high quality, and long durability.
The device is water- and dust-resistant, discreetly integrated into the bike, and difficult to remove. At the same time, it offers one of the most advanced feature sets on the market.
Connected by Comodule
Comodule is a pioneer and market leader in connectivity solutions for e-bikes and has connected more than 750,000 vehicles worldwide in just 10 years.
Christiania BikesIoT devices and app are developed, designed, and manufactured by Comodule—all internally in Estonia, EU.
Why is my Gurdian IoT device not functioning?
The Guardian IoT device is automatically charged through your bike's headlights. The headlights on your bike must therefore be turned on first for your Guardian device to work.
Materials
Front brakes
The type of front brake to be fitted to your Christiania bike varies according to your needs. We offer either mechanical or hydraulic disc brakes with a 203 mm rotor. Both the mechanical and hydraulic disc brakes have direct and extremely powerful braking performance. Alternatively, it is also possible to install mechanical roller brakes as front brakes. Roller brakes require minimal maintenance, do not tend to make noise, and provide a smoother braking experience.
Lights
All cargo bikes with electric assist motors are equipped with two integrated headlights under the box. Each headlight is StvZO, CE, and RoHS certified, has a power output of 1.2 watts, provides 40 lux with a visibility range of 150 meters.
Tires
We fit black CST tires with reflectors on all our cargo bikes. The tires are 24×2.15 (55-507) and can carry loads of up to 145 kg. They have a TPI of 60 and are manufactured with the highest possible anti-puncture properties, including a double-woven carcass, a thin layer of aramid fiber, and a 3 mm anti-puncture layer. The tires are designed for cargo bikes with anti-puncture level 7 and are ECE-R75 approved.
Theft
Prevent your Christiania bike from being stolen
Purchase an approved lock that is permanently attached to the bicycle.
Get an extra chain lock
Lock your cargo bike to something that is fixed in place.
Keep your paperwork safe after you buy the cargo bike.
Take a photo of the cargo bike and the frame number.
Personalize your cargo bike.
Insurance
We recommend that you take out insurance for your model. If you are unlucky enough to have your model stolen, insurance companies will normally require you to provide the frame number of the bike and show your receipt. Contact your insurance company for more information.
Maintenance
Where can I get my model serviced?
We recommend having our models serviced by one of our authorized dealers. You can find dealers near you here.
How often should my model be serviced?
How often your model needs to be serviced depends, of course, on various factors. For example, if your model is used in hilly terrain or to transport heavy loads on a daily basis, it will need to be serviced more often, as the brakes are subjected to greater stress. Our general advice is to have your model serviced twice a year.
Tires and wheels
All tires are inspected for wear and punctures. All tires must have a pressure of between 4 and 6 bar. The wheels are checked for loose spokes and play in the wheel bearings. If the spokes are loose, they must be tightened by your bicycle dealer. If there is play in the wheel bearings, the wheel must be checked by your bicycle dealer as soon as possible.
General maintenance
The frame, wheels, box, etc. should be washed and cleaned regularly to remove dirt. The parts should be wiped with a damp cloth. Avoid dirt in the joints. Check regularly for loose parts and have them tightened by a bicycle dealer if necessary. All visible, moving parts: cables, adjustment screws, moving brake parts (NOT brake discs), chain, pedals, bell, and lock should be lubricated regularly with bicycle oil. Screws, threads, and axles can also benefit from a few drops of oil, and the chain should be tightened if necessary.
Maintenance of wood
Wipe the box inside and out with a damp cloth. The box can be sealed with a thin film of linseed oil applied with a cloth; the bench is also treated with linseed oil, including in the grooves on the side panels.
Hoods and cushions
Hoods and cushions can be hand washed in lukewarm water (max. 40°C). Excessive washing weakens the hood's resistance to water penetration; it is therefore recommended to wipe it lightly with a damp cloth or sponge instead.
Brake systems
It is very important to maintain your braking system regularly to ensure your safety, that of your children, and your surroundings. To ensure maximum safety, our braking systems should only be serviced by qualified technicians. Please contact one of our authorized dealers if the braking power has deteriorated or the braking system is braking unevenly.
Safety conditions
How should the box be loaded?
First and foremost, the box must be loaded carefully. We always recommend loading the box—especially very heavy items—closest to the end (i.e., closest to the handlebars) and lighter items at the front of the box.
General direction links when driving
Of course, how you prefer to ride our models is a personal choice. We recommend the following:
Do not ride too fast – always maintain control of the cargo bike.
Sit upright in the curves and let the front part turn.
Do not stand up while riding, as the cargo bike may sway.
Always drive as straight as possible on ramps and exits.
Do not roll backwards while sitting on the bike; this can damage the rear frame.
Regulatory aspects
How many children am I allowed to transport?
The Danish Transport Authority'sBicycle Orderstates the following:
Chapter 2: § 3. A bicycle must not be designed to carry more than three persons. However, there may be room for up to four children not older than 7 years, cf. § 25.
Chapter 8: § 25. No more persons than the bicycle is designed to carry may be transported on a bicycle. Children under the age of 7 may only be carried on a bicycle if there is a special seat designed for them.
Paragraph 2. Special seats for children must be adapted to the child's weight and height, and there must be a barrier between the child and the wheels.
Paragraph 3. Children carried on a bicycle must be securely fastened.
Paragraph 4. Transporting children must not prevent the rider from having full control of the bicycle or from signaling properly.
Paragraph 5. The rider of the bicycle must be at least 15 years of age when transporting children on the bicycle.
This means that if the children are under eight years of age, the law allows six children on a cargo bike – provided it is designed for this purpose! There must therefore be a special space for each of the children, and they must be secured in place.
On a Christiania bike, you can use our child bench or child seat with accompanying harnesses for your children, or you can permanently attach a car seat or infant carrier for your small child.
The driver of the Christiania bike has the child/children safely in front of them on the cargo box, so they can keep an eye on them at all times, and the sturdy box construction provides the children with good protection.
Do we follow directives and standards?
All our electric versions are classified as EPACS (Electrically Power Assisted Cycles) with a maximum speed of 25 km/h and a maximum continuous rated power of 0.25 kW. This classification means that our electric versions must comply with the Machinery Directive (2006/42/EC). To comply with the Machinery Directive, we have chosen to follow the European standard EN 15194 – and thus also the EMC Directive 2014/30/EU. To comply with these directives, we carry out our own tests, ensure that our subcontractors comply with the requirements, and use independent experts in the field in Denmark.
All our products for children comply with Directive 2005/84/EC, which ensures that children are not exposed to hazardous substances.
Chassis number
Where is the chassis number located?
The frame number is located in different places on our cargo bikes and trailers. On the trailers, the frame number is stamped on the side of the bottom frame. On the yellow galvanized steel frames, we have stamped the frame number on the left side of the plate between the top and bottom tubes. On aluminum frames for rearDrive or frames for cargo bikes without a motor, the frame number is stamped on a plate under the crank box. On midDrive aluminum frames, the frame number is stamped on the seat tube just above the motor housing.
What is the chassis number?
Every bike and trailer we make has its own unique number, called a frame number. Our frame number consists of our own manufacturer's mark "CS," a serial number, and a year mark. We keep track of all our models using the frame number.
How old is my model?
If you send us your frame number, we can give you the exact date when your model was manufactured. You can also find the year yourself by looking at your frame number. The last letter in the frame number indicates the year of manufacture. You can use the following guide to find out when your model was manufactured. The letters A-Z are used, except for I, O, and Y.
