Reflector
The reflector, often thought of as a small addition to your bike, actually plays an important role in cyclist safety, particularly in low-light conditions. It's a device that reflects light back to its source, meaning it glows when illuminated by car headlights, for example. This considerably increases the bike's visibility and, by extension, the cyclist's safety.
Reflectors are usually placed in several strategic positions on the bike: on the wheels (in the spokes), at the front (often white), at the rear (red) and sometimes on the pedals. Each position is designed to increase the bike's visibility from different angles and in different situations.
Wheel reflectors are particularly effective at showing the bike's movement and presence in the dark. As they move with the wheels, they create a dynamic visual effect that attracts attention. Front and rear reflectors, meanwhile, help identify the direction in which the bike is moving.
Although reflectors are useful, they are not a substitute for active lighting, such as front and rear lights. It is strongly recommended to use both reflectors and lights for optimum visibility, especially at night or in fog or rain.
Reflector installation is generally straightforward and requires no special tools. They are often included with new bikes and can be easily added or replaced if necessary.
In terms of maintenance, reflectors require little care. It's important to keep them clean so that they remain effective. A dirty or damaged reflector may not reflect light properly, reducing the bike's visibility.

Bike wheel
The bicycle wheel is a fundamental element that has a considerable impact on the performance, comfort and style of your bike. Made up of several parts - the rim, spokes, hub and tire - each component of the wheel has its own importance and contributes to the overall cycling experience. The rim forms the outer edge of the wheel and is where the tire is mounted. It plays a crucial role in the bike's handling and responsiveness. Rims can be made from a variety of materials, such as aluminum or carbon, each offering a unique balance between strength, weight and cost. Carbon rims are often preferred for performance bikes because of their lightness and rigidity, while aluminum is commonly used for its strength and affordability. Spokes, which attach the hub to the rim, are essential for wheel strength and stability. A higher spoke count increases the wheel's strength and durability, while a lower spoke count reduces weight and increases aerodynamics. Spoke tension is also important to keep the wheel aligned and balanced. The hub, at the center of the wheel, contains the bearings that allow the wheel to rotate around the axle. There are different types of hub, including those with integrated braking systems, such as disc brakes, or dynamo hubs for powering bicycle lights. The rim-mounted tire is the interface between the bike and the road or trail. Tires vary considerably according to use - from smooth, narrow tires for high-speed road bikes to wide, knobby tires for mountain bikes. Selecting the right tire has a significant impact on traction, rolling resistance and comfort. Wheel maintenance is essential to ensure bike safety and performance. This includes regular checks on the condition of rims, spokes, hub and tires, as well as periodic adjustments to ensure that everything is properly aligned and working properly. In short, bicycle wheels are much more than just spinning circles. They are the result of sophisticated engineering and play a crucial role in every aspect of cycling, from speed and stability to the bike's aesthetics.

Bike rims
The bicycle rim, an essential component of the wheel, plays a crucial role in cycling performance and safety. It is the link between the tire and the rest of the bike, supporting the rider's weight and absorbing the impact of the terrain. Rims come in a wide range of materials, shapes and sizes, to suit different types of bike and riding styles. The most common materials are aluminum and carbon. Aluminum rims offer a good balance between strength, weight and cost, while carbon rims are lighter and stiffer, but generally more expensive. Rim shape also influences bike performance. Low-profile rims are common on city and mountain bikes, offering good handling and strength. On the other hand, high-profile rims, often seen on road bikes, improve aerodynamics for increased speed. Rim width is also an important factor. A wider rim offers better support for the tire, resulting in better grip and stability, especially for mountain biking or cycling on mixed terrain. For road bikes, narrower rims are preferred to reduce wind resistance and weight. The rim also plays a role in the bike's braking system. For bikes equipped with rim brakes, the rim surface must be smooth and free of imperfections to ensure effective braking. With the emergence of disc brakes, this constraint is less present, but the quality of the rim remains essential to the bike's overall safety. In short, the bicycle rim is a vital component that directly influences the rider's ride quality, safety and performance. Whether for city commuting, road racing or mountain adventures, choosing the right rim is essential for an optimal cycling experience.

Tubeless tire
The tubeless tire is a major innovation in the world of cycling. Designed to improve performance and ride comfort, this type of tire eliminates the need for a traditional inner tube. Instead, the tire forms a hermetic seal directly with the rim, making the configuration more resistant to punctures and offering other notable advantages. One of the main advantages of tubeless tires is their resistance to pinch punctures, a common problem with traditional inner tubes. What's more, in the event of a puncture, the sealing fluid present in the tubeless tire can automatically seal small leaks, allowing you to continue riding without any significant interruption. Another major advantage of tubeless tires is the ability to run at lower pressures without the risk of tube pinching. This translates into better traction and control, especially on uneven terrain, and a more comfortable ride thanks to better absorption of shocks and road vibrations. However, switching to tubeless tires may require specific or tubeless-compatible rims, as well as a more complex initial installation. The installation process involves applying sealing tape to the rim, installing the tire, then adding sealing fluid before inflating the tire to create a hermetic seal. Although this installation can be carried out by an experienced cyclist, many choose to entrust it to a professional. Tubeless tires also offer better performance in terms of rolling resistance. Without the internal friction of an inner tube, they can roll more freely, which can contribute to a slight improvement in speed and fuel efficiency. In terms of maintenance, tubeless tires require periodic replacement of the sealing fluid to maintain their ability to self-heal small punctures. They may also require a little extra attention to ensure they remain well sealed and inflated to the right pressure.

Bike locks
A bicycle lock is an essential safety device for any cyclist wishing to protect their two-wheeler against theft. With the number of bicycle thefts on the rise, choosing a reliable lock is more than just a precaution; it's a necessity. Anti-theft devices come in a variety of forms, each offering different levels of security and ease of use. The most common are U-locks, chain locks and cable locks. U-shaped locks are considered one of the safest options. Their U-shaped design, usually in hardened steel, effectively resists cutting, twisting and levering. They are ideal for securing your bike in high-risk areas, but their rigidity can sometimes limit locking options. Chain locks, consisting of metal links covered with fabric or plastic to protect the bike frame, offer great flexibility. They can be used to secure the bike to a variety of fixed objects, and are easier to transport than U-locks. However, they can be heavier and less resistant to specialized cutting tools. Cable locks, on the other hand, are lightweight and easy to handle. They are ideal for quick stops or in areas with a low risk of theft. Although they offer less security than U-locks or chain locks, their ease of use and portability make them popular with urban cyclists. Some locks incorporate advanced technologies, such as audible alarms or electronic locking systems, for extra protection. It's also important to consider the lock's locking system; key locks are common, but combinations can offer the convenience of not having to carry a key. The effectiveness of the lock also depends on its correct use. We recommend always locking the frame and front wheel to a fixed, immobile object. Using two different types of lock, such as a U-lock and a cable lock, can provide additional security.
