Mega Sale - Helmets - additional info

Helmets are a must-have biking accessory that can save you from many unpleasant injuries. Knee and elbow protectors keep your limbs safe, while bike gloves ensure comfort for your hands. Bike manufacturers such as BBB, Spokey, Crazy Safety, Tempish, or Tern also offer a wide range of helmets, protectors, and gloves.

Child safety first

Children really shouldn’t ride a bicycle without a helmet. In order to make wearing it as fun as possible, children's helmets are manufactured in bright colours and with neat 3D effects. Crazy Safety, for example, makes cool Spiderman-themed bike helmets. In some countries, children and teenagers under 18 years of age are even legally obligated to wear a helmet when biking. Adults generally aren’t, but it doesn’t mean they shouldn’t. If you are a cyclist or skater and still don’t have one, you are exposing yourself to many unnecessary risks. Skateboard helmets are designed for urban surroundings and are aimed at fans of rollerblades and skateboarding. Skateboard helmets are made of hard plastic for maximum head protection during an unexpected fall on hard paved road surface.

Protectors for cyclists and skaters

Our selection also includes knee and elbow protectors in different sizes for the fans of in-line skating and skateboarding. They are made of hardened plastic and provide maximum protection for the most vulnerable body parts. These protectors are equally suitable for cyclists, especially those who ride mountain bikes and navigate urban parks and rough terrain. Bike gloves are another handy accessory, as they provide much-needed comfort for your hands during long trips. Bike gloves are designed to not restrict your movement and make sure your hands don’t overheat.
