Go electric, without changing bike...

We've tested the Cosmopolit electric wheel: it's cheap and a very practical way of transforming your mechanical cycle. Is it a good deal? Is it worth buying?

The Cosmopolit electric wheel is an eye-catching product, especially for those looking to convert a conventional bike into an electric bike without investing in an entirely new model. Here's a review of this product in terms of price, practicality and performance to determine whether it's a good deal.

Cosmopolit electric wheel highlights

1. Competitive prices One of the biggest advantages of the Cosmopolit wheel is its affordable price. Compared with other solutions on the market, it offers a less expensive alternative for those who want to electrify their bike. This makes it particularly attractive for occasional cyclists or those who want to try out electrification without breaking the bank.
2. Easy to install The Cosmopolit wheel concept is based on simplicity of installation. It replaces the front wheel on your bike, and installation requires no advanced technical skills. The wheel is supplied with all the necessary accessories, including a battery and pedalling sensor.
3. Practical and portable The Cosmopolit wheel is a practical solution for those who need temporary or occasional electric assistance. It can be easily removed or installed as required, and the removable battery makes it easy to recharge, even if you don't have a garage or space for your bike.

Points to consider

1. Performance Although practical, the Cosmopolit wheel offers limited assistance in terms of power. It's better suited to flat urban journeys than hilly roads or long distances. If you're looking for powerful assistance for difficult terrain, it may not be enough.
2. Autonomy Battery autonomy: Battery autonomy is adequate, but it depends very much on the level of assistance used and the riding conditions (rider weight, terrain, etc.). For daily journeys in town, it may be sufficient, but for longer rides, you'll need to plan a recharge or be prepared to pedal without assistance.
3. Durability As with any affordable product, it's important to consider long-term durability. The components are of decent quality, but perhaps less robust than those of top-of-the-range models. For intensive use, it's a good idea to ask about warranties and the availability of spare parts.

Technical characteristics of the Cosmopolit Electric Wheel

1. Engine type :
   • The Cosmopolit wheel is fitted with a brushless motor integrated into the front wheel hub. This type of motor is renowned for its reliability, low maintenance and energy efficiency.
2. Power :
   • The motor generally develops 250W of power, which is standard for electric city bikes. This gives a maximum assisted speed of around 25 km/h, in line with European regulations for electric bikes.
3. Assistance modes :
   • The wheel offers several levels of assistance that you can adjust to suit your needs. These modes allow you to modulate the power delivered by the motor, which is useful for adapting your effort according to the terrain or your physical condition. In general, you'll find levels ranging from minimum assistance to save battery power to maximum assistance for rapid climbs or acceleration.
4. Autonomy :
   • Battery life varies according to the level of assistance used and driving conditions. On average, the Cosmopolit wheel offers a range of 30 to 50 km, which is sufficient for everyday urban journeys. However, on longer journeys or with constant maximum assistance, the range could be reduced.
5. Battery :
   • The wheel is fitted with a removable lithium-ion battery. Its typical capacity is around 7 to 10 Ah (ampere-hours), with a voltage of 36V. The battery is designed to be lightweight and easy to recharge. It will take between 3 and 5 hours to fully recharge, depending on the capacity of the battery.

Installation and ease of use

1. Easy to install :
   • Installing the Cosmopolit wheel is designed to be quick and easy, even for the uninitiated. Simply replace your front wheel with the Cosmopolit wheel, attach the pedal sensor to the pedal or frame, and connect the controller (usually a small box or device that mounts on the handlebars). No complex wiring or technical skills are required.
2. Compatibility :
   • The Cosmopolit wheel is compatible with the majority of classic bikes with standard size front wheels (generally 26 to 28 inches). Before buying, however, it's advisable to check compatibility with your specific model, especially if you have a bike with particular specifications.
3. Use :
   • Once installed, the Cosmopolit wheel is easy to use. You can control the assistance via a screen or a button on the handlebars, and the battery can be removed for recharging at home, which is very practical if you don't have a garage or secure space to leave your bike plugged in.

How much does it cost?

The price of the Cosmopolit electric wheel varies according to retailers, promotions and the specific characteristics of the model (such as battery capacity). In general, the price is around 400 to 600 euros. This makes it an affordable option compared to buying a full electric bike, which can easily cost well over €1,000.

To get the best price, it's advisable to compare online offers and check user reviews, as promotions or discounts may sometimes be available.

Is it worth buying?

The Cosmopolit electric wheel is an affordable and practical way to go electric without changing your bike. It's easy to install, offers sufficient assistance for urban journeys, and its competitive price makes it accessible to a wide audience. It's an excellent choice for those looking to electrify their bike for journeys around town or for occasional use. However, for demanding users or longer journeys, it would be wise to consider the limits in terms of power and range.
