In cycling, rim height significantly impacts the aerodynamics, maneuverability and weight of the wheel. Basically, the higher the rim, the greater the aerodynamic advantage. The lower the rim, the more agile and maneuverable the handling.

Each of the current standard wheel sizes ( 27.5" and 29") has advantages and disadvantages. The larger the wheel, the better it rolls over obstacles. However, as the size grows, so does the weight and therefore the rotating mass, which decreases the bike's liveliness.

We develop all FEREI products for a specific use and the construction of the product is based on the stresses expected as a result of that use. The wheel categories represent the different uses.

All FEREI lamps come complete with installation instructions. If you've lost your installation instructions, you can search for the product and download them on our instructions page.

The Kelvin (K) is the unit of color temperature. Whether it is white or yellow light, FEREI chooses the most suitable color temperature, which will not cause visual fatigue.

· If the lights is used infrequently, the battery should be recharged a minimum of every three months (regardless if no dimming is observed). · Additionally, If the light is going to be in storage or not used for three months or more, the battery should be charged and then removed from the light and stored in a safe place.

No, our spotlights can only be activated when the vehicle is working, and the spotlights work with the electricity generated by the engine.
