We recommend using your belt drive inspect at least once a month. This depends on how often you cycle. With heavy use, it is wise to do it more often. During your inspection, look carefully for signs of wear such as small cracks on the sides of the belt. Frayed, or visible damage to the teeth of the belt are also important.

Also pay attention to the alignment of your belt. A misaligned belt can cause excessive wear. Eventually, this can lead to drive failure. Check that the belt runs nicely down the center of the sprockets. A properly aligned belt also makes less noise while cycling. If you hear unusual noises, it may indicate an alignment problem.

Joeri advises, "I always tell customers: a minute's look a month can save you a lot of misery. Especially with our CityX, you see problems early."

Being proactive with inspecting your belt drive prevents bigger problems in the future. It ensures that you are always ready for your next ride, with no unexpected breakdowns along the way.

Cleaning a belt drive is easier than chain maintenance. But it must be done correctly. Start by removing coarse dirt with a soft brush. Then use a damp cloth with mild soapy water to wipe the belt clean. Rinse with clean water and dry the belt thoroughly.

Avoid using aggressive cleaners or solvents. These can damage the carbon fibers in the belt. Unlike a chain, you do not need to lubricate the belt. In fact, this is not recommended because lubricants can attract dirt and interfere with the belt's function.

For optimal performance, it is important to keep the gears clean as well. To do this, use an old toothbrush to get between the teeth. Remove any jammed dirt or stones that may damage the belt while cycling.

Joeri emphasizes, "The beauty of our UrbanX is that you can just rinse it off. No greasy mess like with a chain."

Proper belt tension is crucial to the optimal performance of your belt-driven fatbike. A belt that is too loose can skip while cycling. A belt that is too tight can cause excessive wear on both the belt and the bearings in your drivetrain.

To check the tension, you can press the belt in the middle between the sprockets about 1-2 cm. If the belt yields more than this, it's probably too loose. You can also use Gates' smartphone app. This is specially designed to measure the correct belt tension via the sound frequency of a tapped belt.

Adjusting belt tension is done by moving the rear wheel slightly backward or forward. Most fatbikes with belt drive have a tensioning mechanism or adjustable dropouts that simplify this process. If you are unsure about the proper tension, consult your bike's manual. Or seek advice from a professional bike shop.

Joeri explains: "At our CityX is a convenient tensioning mechanism. But let us do the first year for a while, then you'll learn how to do it."

The thick tires of your fatbike are characteristic of this type of bike and require specific attention. Proper tire pressure is essential and varies with the surface. For soft surfaces such as sand or snow, a lower tire pressure (0.5-0.8 bar) is optimal for more grip. On paved roads, you can increase the pressure (1.0-1.4 bar) for less rolling resistance.

Regularly check your tires for wear, broken-in sharp objects and damage. Pay particular attention to the sides of the tires. These are vulnerable to cuts when you drive over sharp stones or obstacles. Remove jammed stones from the tread to prevent them from penetrating deeper into the tire while driving.

Remember that fatbike tires, despite their rugged appearance, also wear out and need periodic replacement. A worn tire offers less grip and comfort. This negatively affects your riding experience and can even be dangerous in challenging conditions.

Joeri notes, "Customers often forget about the tires. But with our UrbanX, it is precisely the tires that make the difference on different surfaces."

The frame of your fatbike deserves as much attention as the drivetrain and tires. Clean your bike regularly, especially after rides in muddy or wet conditions. To do this, use warm water with a mild soap and a soft sponge or brush. Avoid pressure washers, as they can force water into bearings and other sensitive parts.

After cleaning, it is important to dry your bike thoroughly. Pay special attention to the joints between different frame tubes and hard-to-reach corners where water can remain. For aluminum frames, you can use a protective wax or polish to protect the material from the elements.

Regularly check all the nuts and bolts on your bike and make sure they are tight. But not over-tightened. Excessive force can damage threads or even break components. Use a torque wrench for crucial components such as stem, seat post and cranks to ensure proper tension.

Joeri advises, "A clean CityX is a happy CityX. Too often I see bikes that have not been properly cleaned for years."

If you don't use your fatbike for an extended period of time, such as during the winter months, there are some steps you can take. These will ensure that your bike stays in top condition. Start with a thorough cleaning and dry your bike completely. Check and correct the belt tension so that it is not too tight during the storage period.

For the electrical components, it is important to charge the battery approximately to 60-80%. Store it in a cool, dry place. Lithium-ion batteries maintain their charge best at room temperature, neither too hot nor too cold. It is advisable to check the battery every two months and recharge if necessary to prevent deep discharge.

Preferably store your fatbike indoors, in a dry room with a constant temperature. If possible, hang your bike on a wall or place it on a stand to prevent pressure on the tires. If storing outside is the only option, use a breathable but waterproof bike cover. This will protect against rain, UV rays and dust.

Joeri emphasizes, "Our UrbanX prefers to be indoors. A bit like a good wine - cool, dry place and it stays perfect."

With an electric fatbike, the electrical components are the heart of your bike. The battery deserves special attention: never charge it in temperatures below freezing. Avoid complete discharge, which can shorten the service life. Keep the battery contact points clean and regularly check the casing for cracks or damage.

The motor generally requires little maintenance. But keep the casing clean and regularly check for water ingress. Especially after riding in wet conditions. Also listen for unusual noises while driving. These may indicate problems with the engine or drive train.

Periodically check all electrical connections and cables for damage or disconnected connectors. Protect the display from extreme weather conditions and clean it gently with a slightly damp cloth. Do not use harsh cleaning agents that may damage the coatings.

Joeri cautions, "The electrical components of our CityX are very reliable. But water and electronics remain each other's enemies."

Although many maintenance tasks can be performed by yourself, there are times when professional help is necessary. If you experience problems with the belt drive that you cannot fix yourself, such as skipping the belt despite correct tension or damage to the belt, it is wise to seek help.

It's also better not to take chances with electrical problems such as unexpected failure of support, error messages on the display or problems with the charging system. A specialist has the right diagnostic equipment and expertise to safely repair these complex systems.

We recommend at least once a year to have a full maintenance service performed by a professional. Even if there are no obvious problems. This involves checking all crucial parts, including bearings, brakes, electrical components and, of course, the belt drive. Preventive maintenance can prevent bigger problems and ensure that your bike remains safe and reliable.

Joeri emphasizes, "We know our UrbanX inside out. Just have the annual check done by us, then you can be sure that all is well."

Your maintenance routine should change with the seasons. In winter, when you have to deal with rain, snow and road salt, extra protection is necessary. Clean your bike more often and pay extra attention to removing salt. This can cause corrosion to metal parts. Consider using a protective spray for the frame and components.

During the summer, when you are likely to drive more frequently and for longer periods of time, it is important to check your tires, brakes and belt pressure more regularly. Higher temperatures can also affect your electrical components. Keep the battery cool and avoid prolonged exposure to direct sunlight.

The transition between seasons is a perfect time for a thorough maintenance checkup. Check your entire bike and pay extra attention to parts that were heavily used during the previous season. This will ensure that your bike is ready for the specific challenges of the upcoming season.

Joeri notes, "In the winter, I see that our CityX needs extra maintenance. That salt is really the enemy of any bike."

Properly functioning brakes are essential to your safety. Check brake pads regularly for wear and replace them promptly. For hydraulic brakes, watch the fluid level and any air bubbles in the system. These can reduce braking power. Many fatbikes have disc brakes, which perform well in various weather conditions. But they do require regular checking for alignment and wear.

If your fatbike is equipped with a gearing system, such as an internal hub gear, check the adjustment according to the manufacturer's guidelines. Internal hub gears work well with belt drives and require less maintenance than derailleur systems. But must be inspected at appropriate times.

Don't forget to check the cables and housings of your brake and gear systems for wear and smooth operation. Replace worn or damaged cables promptly to prevent them from breaking while riding. This can create potentially dangerous situations.

Joeri advises, "The brakes on our UrbanX are top-notch, but check them regularly. Safety always comes before everything else."
