You have questions, we have answers!

Why choose fatbikeklaar.nl?

We specialize in tunable fatbikes and parts. Over 500 happy customers have gone before you. Fast delivery, sharp prices, and customer service that truly thinks along with you.

Can I have my fatbike tuned by you?

Our fatbikes are tunable, and we also supply individual parts to upgrade your fatbike. Please note: tuning is only permitted on private property, not on public roads.

Is a fatbike still legal?

Yes, a fatbike that complies with current regulations (max. 25 km/h pedal assist and a 250W motor) is fully legal on public roads. Tuned models may only be used on private property.

What are the new fatbike rules for 2026?

As of 2026, stricter rules apply around age, helmet requirements, and vehicle specifications. Check our information page for the latest details.

Do you need a driver’s license for a fatbike?

You don’t need a driver’s license for a regular fatbike with pedal assist up to 25 km/h. You do for tuned models above that limit. Keep in mind those are only allowed on private property.

Why buy a fatbike?

A fatbike is comfortable, fast, and ready for any terrain, from city streets to the beach. Ideal for commuting and for fun. And with our tunable models, you get even more out of it.

Do you need a helmet on a fatbike?

A helmet is strongly recommended for your own safety. From 2026, a helmet requirement will be introduced for certain fatbike categories.

Can I tune an Ouxi C80 Mini or QMWheel V20 Mini?

No. The Ouxi C80 Mini, C63 Mini and the QMWheel V20 Mini cannot be tuned. There is no tunable controller or tunable display for these models; they stay restricted to 25 km/h. Do you want to tune after all? Then have a look at the Ouxi C80, V8 or GT2000 and the QMWheel V20 or V20 Pro.

Fatbike Drivetrain at FatbikeKlaar.nl

Are you looking for parts for your fatbike's drivetrain? At FatbikeKlaar.nl you will find a complete range of fatbike drivetrain parts for Ouxi and QMWheel models. Whether you want to replace a worn chain, upgrade your crankset, or need a new motor: you can easily order the right parts online from us.

A well-functioning drivetrain is essential for a smooth and efficient riding experience. With original parts, you maintain optimal performance and extend the lifespan of your fatbike.

What does the fatbike drivetrain include?

The drivetrain is the heart of your fatbike and consists of multiple parts that work together to transfer power from the motor and your legs to the rear wheel. At FatbikeKlaar.nl you will find the full range:

  • Chains: ensure power transmission between crankset and cassette
  • Cassettes: the sprocket cluster on the rear wheel
  • Cranksets: where the pedals are attached
  • Motors: the electric assist of your fatbike
  • Pedals: for grip and power transmission
  • Bottom brackets: the connection between crankset and frame

Original drivetrain parts for Ouxi and QMWheel

For Ouxi and QMWheel fatbikes, it is important to choose parts that fit your model perfectly. Original drivetrain parts connect seamlessly to the other components, prevent assembly problems, and reduce the chance of wear or defects.

At FatbikeKlaar.nl, all parts feature a plug & play system, allowing you to easily disconnect and replace a defective part.

When to replace drivetrain parts?

Drivetrain components wear out with intensive use. Signs that replacement is needed:

  • A rattling or squeaking chain
  • Hesitation during shifting
  • Reduced motor performance or range
  • Play in the crankset or pedals

By replacing parts in time, you prevent damage to other components and maintain a smooth riding experience.

Why order fatbike drivetrain from FatbikeKlaar.nl

  • Wide range of original Ouxi and QMWheel drivetrain parts

Frequently asked questions about fatbike drivetrains

How often should I replace my fatbike chain? With daily use, replacement every 2,000 to 3,000 kilometers is common. Regularly check for stretch and wear.

Will a universal chain fit my Ouxi or QMWheel? Not always. Preferably choose an original chain that is tailored to your specific model.

Can I replace the motor myself? Thanks to the plug & play system, it is possible, but if in doubt, we recommend engaging the repair service.

Should I replace the cassette and chain together? Often yes. A new chain on a worn cassette wears faster, so replacing them together provides the best performance.

How fast will my order be delivered? If you order before 23:59, you will receive your parts the next day.

Welcome to Fatbikeklaar.nl, your reliable online shop for fatbikes, e-bikes and electric folding bikes. Whether you ride through the city every day or are looking for extra comfort and stability, at Fatbikeklaar.nl you will find a carefully selected range for every type of ride.

All our fatbikes and e-bikes are 100% legal for use on public roads, fitted with 250W motors and wide tyres for extra grip and stability. We also offer a wide range of electric folding bikes, ideal for commuting and daily use.

With 65+ reviews and 500+ satisfied customers, at Fatbikeklaar.nl you choose proven quality, service and reliability. You can also take advantage of our current Autumn Deals, available online while stocks last.

Why choose a fatbike?

A fatbike is more than an e-bike with fat tyres. It is a bike that combines comfort, stability and ease of use with powerful pedal assist for everyday rides. Whether you commute to work, take the children to school or ride outside the city at the weekend: at FatbikeKlaar you order a fatbike that suits your riding style.

Comfort thanks to wide tyres

The 20×4 inch tyres of a fatbike absorb the bumps that make an ordinary e-bike bounce. You barely feel cobbles, speed bumps, tree roots and manhole covers. Because fatbike tyres are ridden at low pressure (around 1.0-1.4 bar), you effectively have natural damping built in, without needing an expensive suspension fork. On longer rides you clearly notice that in your back, wrists and neck.

Stable on every surface

Thanks to the wide contact surface you keep grip in situations where narrow city bike tyres slip: wet autumn leaves, loose gravel, cobblestones, muddy cycle paths and wet tram rails. That makes a fatbike particularly interesting for anyone who keeps cycling all year round and does not want to switch between different bikes for different seasons.

Ideal for commuting

The fatbikes and e-bikes at FatbikeKlaar are fitted with a 250W motor and deliver pedal assist up to 25 km/h. That places them under the same rules as an ordinary e-bike: no driving licence, no helmet requirement and no number plate requirement. With a range of 40 to 60 km on a single battery, and up to 120 km on models with a dual battery, you ride return commutes such as Amsterdam-Haarlem or Antwerp-Mechelen without charging in between.

Do you need a driving licence for a fatbike?

No. You do not need a driving licence to ride a fatbike. Fatbikes fall under the rules for normal e-bikes (250W motor and pedal assist). As a result there is no driving licence or helmet requirement.
