Are you dreaming of transforming your classic bike into a high-performance electric bike that is suitable for your daily commute? The Reebike Cosmopolit electrification kit could be the ideal solution! Designed to fit a wide variety of bikes, this kit has an impressive compatibility rate of 9 out of 10 bikes, allowing the majority of cyclists to modernize their bike without having to change it.
However, to ensure that your bike is compatible with this kit, it is essential to check a few technical characteristics. In this article, we will review the criteria that must be met to ensure optimal installation and smooth operation of the Cosmopolit kit on your bike.
Check the compatibility of your bike with the Cosmopolit Kit
Before you jump into purchasing the Cosmopolit kit, it is important to make sure that your bike is compatible. An electrification kit consists of a motorized wheel and a battery system, requiring precise specifications to install correctly. Here are the three essential points to check.
No Drum Brakes
Drum brakes, although effective, are not compatible with the Cosmopolit kit. The latter is designed to fit bikes equipped with disc brakes or rim brakes , more commonly used on city bikes, road bikes and many mountain bikes. These types of brakes allow for better adaptation of the motorized wheel, ensuring both safety and efficiency.
Why are drum brakes not compatible? This is mainly due to their closed design and internal structure that complicates the installation of a motorized wheel. For users of bikes with drum brakes, it may be necessary to consider a modification of their braking system to be able to install the Cosmopolit kit.
No through axle
The thru axle is a type of wheel attachment commonly used on some recent models of bicycles, particularly mountain bikes. However, the Cosmopolit kit is not compatible with this type of attachment. It is therefore imperative that your bike is equipped with a classic axle , whether it is a nut or a quick release. These axles allow for simplified and secure mounting of the motorized wheel.
If your bike uses a thru-axle, it may be possible to replace it with a standard axle, although this modification may require professional assistance. Check with a bike technician or shop to see if such a conversion is possible and safe for your model.
Fork drive and spacing
The center distance and fork spacing are crucial dimensions for installing the Cosmopolit wheel. Make sure that:
The center distance (the distance between the two attachment points on the fork) measures at least 8.5 cm (or 85 mm). This width ensures that the Cosmopolit wheel can fit perfectly and operate smoothly.
The spacing between the fork arms must be at least 8 cm and a minimum height of 15 cm . This dimension is necessary for optimal installation, as it prevents the motorized wheel from rubbing or being poorly positioned. Note that some forks, particularly V-shaped or very tapered forks, do not respect this spacing and are therefore not compatible with the Cosmopolit kit.
These dimensions can be measured using a caliper to ensure accuracy. If in doubt, a trip to a bike shop can provide you with accurate measurements and a professional opinion.
Specific compatibilities: Cargos and Tandems
If you have a special bike, such as a cargo bike or a tandem , the Cosmopolit kit is designed to fit under certain specific conditions:
Cargo Bikes
Cargo bikes are becoming increasingly popular for urban commuting and cargo transport. The Cosmopolit kit is compatible with cargo bikes provided they have a single front wheel . This restriction is in place for reasons of stability and motor efficiency. With a single front wheel, weight distribution and steering are better controlled, ensuring optimal use of the Cosmopolit kit.
Tandem Bikes
For tandem bikes, which usually feature larger wheels and a longer frame, the Cosmopolit kit is also compatible, provided that the wheels have a diameter between 26 and 29 inches . This ensures that the kit's motorized wheel fits perfectly to the size of the bike and provides a comfortable and safe pedaling experience.
If in doubt, it is always best to consult a professional who can check the compatibility of your cargo or tandem bike with the Cosmopolit kit.

- Preparation : Make sure your bike is clean and ready for installation. Prepare the necessary tools (often a wrench is included with the kit).
- Removing the Front Wheel : Detach the current front wheel from your bike, being careful not to damage the brakes or cables.
- Installing the motorized wheel : Place the Cosmopolit wheel in place of your front wheel and secure it securely, ensuring that the dimensions are respected to avoid any play.
- Battery and Cable Attachment : Mount the battery to the rack or frame, then connect the supplied cables. Make sure everything is securely connected and in place for safe use.
