Bike helmets are a crucial accessory for cyclists, as they prevent head injuries in case of falls or collisions. These helmets are frequently used by professional athletes, tourists and extreme cycling enthusiasts ebikes buy. Often, parents also buy bicycle helmets for their children to prevent serious injuries..
Why its necessary to have a high quality bike helmet
Now, I'll share some not-so-cheerful statistics. According to research, in Canada, about 75 people die annually from injuries caused by bicycle accidents, and 5,000 are treated in emergency departments. There, bicycles are very popular, here, they are mostly used by people aged 25 to 44, primarily for leisure activities. In Canada, the lack of proper bike lanes is one of the reasons for the 5% increase in bicycle-related fatalities in the first six months of 2022 (116 people died, and 1,842 were injured).
However, the same Canadian researchers claim that bike helmets reduce the risk of traumatic brain injuries by 50-60% and facial injuries by 20-25%. This is due to the bike helmet's design:
Outer Shell:
Made of polystyrene with a plastic coating. This coating determines the bike helmet's appearance (color, shape, number of ventilation holes) and helps distribute the impact force;
Base:
Made of polyurethane or polystyrene. These are elastic materials that compress upon impact, protecting the head from injuries. According to the Bike Helmet Safety Institute, the base is disposable; if you hit the ground with the helmet, it should not be used again;
Lining:
Provides a comfortable fit on the head and absorbs sweat, easily detachable for washing;
Straps:
Secure the bike helmet on the head. Helmets are also made from carbon and fiberglass, providing reliable protection even during very strong impacts.
Types of Bike Helmets
Cross-Country:
Protects the top of the head, intended for city walks. It is lightweight (100-150 g) and has good ventilation;
Used by athletes, with more ventilation holes (at least five), improved aerodynamic properties, and lightweight (150-200 g);
Bowl:
Designed for tricks, so it has enhanced protection and completely covers the head. This model lacks ventilation;
Covers the head and lower part of the face. Made for extreme off-road riding and motocross;
Suitable for athletes participating in track races. Its design lacks ventilation holes, and the shape is streamlined;
Also created for ring speed races on the track. It has a teardrop shape and a heavy weight (from 300 g);
The main difference in this model is a robust fixation system and a reinforced outer layer (with the addition of carbon or nylon fibers). Men's and women's helmets can differ in design and color, but most often, manufacturers offer unisex bike helmets; only the size needs to be chosen. Helmets for children are usually universal and feature bright designs.
How to choose e-bike helmet:
Size
A correctly sized helmet guarantees comfort and safety, so it should be tried on when purchasing. Models with an adjustable size are tailored individually.
Fit
When wearing the helmet and fastening the straps, pay attention to your feelings: the helmet should not sit too loosely or, conversely, too tightly and press on your head, and the straps should not cut into your skin. When moving your head, a slight deviation of the model to the sides is permissible, but not sliding forward or backward. With the correct fit, the helmet occupies a horizontal position, covering both the forehead and the back of the head.
Fixation
The best option is when the clasp passes through the top surface of the shell and attaches to it (this is more reliable). Straps fixed on the side surfaces do not guarantee good fixation, and the helmet may come off during a fall. The fastener should be able to be unfastened with one hand.
Ventilation
Remember that the more holes in the helmet, the better. Models equipped with a special air circulation system can also be chosen.
Weight
Heavy models (from 300 g) put a lot of pressure on the neck, so lighter ones are preferable, although they are more expensive.
Safety
It’s great when children's helmets have reflective stickers, and adult ones have a small light. There may also be additional soft inserts on the inside of the helmet.
Quality
It is necessary to check the condition of the inner layer and the outer shell. They should not have any cracks, dents, or other defects.
How to repair Bike Helmet
Repairing bike helmets is generally not recommended. Helmets are designed to protect your head by absorbing the impact during a crash, which often involves the helmet sacrificing its integrity to disperse the energy away from your skull. Once a helmet has been compromised, either through visible damage or an impact, its ability to protect is significantly reduced, and it should be replaced rather than repaired.
Why You Shouldn't Repair a Bike Helmet
- Safety Integrity: The materials used in helmets, like EPS (expanded polystyrene) foam, are designed for one-time impact absorption. After an impact, the foam compresses and loses its protective capabilities. This damage might not always be visible.
- Hidden Damage: Cracks, dents, or compromised structural integrity may not be visible on the helmet's surface but can significantly reduce its effectiveness.
- Manufacturer's Warranty: Many manufacturers advise against repairing helmets because unauthorized repairs can further compromise the helmet's safety. Some offer a replacement program for helmets that have been damaged.
What You Can Do Instead of Repairing
- Inspect Regularly: Regular inspection can help you identify when it's time to replace your helmet. Look for cracks, dents, or any signs of wear in the foam or outer shell.
- Clean Carefully: You can clean your helmet with mild soap and water to maintain its appearance and hygiene. Avoid using harsh chemicals or solvents that can degrade the helmet materials.
- Replace Parts When Possible: Some helmet components, like the fit system, straps, or padding, can be replaced if they wear out or get damaged. Check with the manufacturer for replacement parts.
- Replace After Impact: Always replace your helmet after a significant impact or crash, even if it looks okay. The internal damages are not repairable and will not provide the necessary protection in future impacts.
- Follow the Manufacturer's Guidelines: Consult your helmet's manual for care instructions and adhere to the manufacturer's replacement advice, typically every 3 to 5 years, depending on use and exposure to elements.
Additional Questions about Helmets
What can and can't you save on when buying a bicycle helmet?
When buying a helmet, it’s better not to skimp and choose worthy European brands that have passed the necessary checks and certifications. The quality of plastic (on cheap helmets, the plastic is such that after a blow, it has to be dug out from under the skin) and foam matters. In cheap models, the foam is just too hard. There's no big difference between hitting your head on the ground or on the helmet.
What materials should a quality bicycle helmet be made of?
The helmet should be made of quality materials: durable plastic, supplemented inside with foam, and equipped with a protection system, for example, MIPS.
What are the main protective elements a bicycle helmet should contain?
A frame made of quality foam, an impact-softening system (ideally MIPS), and durable plastic that bends upon impact rather than shattering into hundreds of fragments.
When is it time to replace a bicycle helmet with a new one?
After the first impact. Even if the helmet has not cracked, it can lose its structural strength. Without damage - as long as you like it, keep riding.
Conclusion
Quality helmets are like bicycle brakes - they're a matter of life and death. It's essential to purchase the highest quality helmet and have full confidence in its reliability. E-bikes can accelerate up to 40 mph, which is quite a serious speed where one needs to be cautious and protected. This was just the first part of our helmet selection. I hope you liked it.
