Founded in 1945, Bell has become a world-renowned helmet manufacturer, including Bell's Voit helmet in the 2008 Tour de France.
 
The safety standard for bicycle helmets was first proposed by the Consumer Products Safety Commission (CPSC) in the United States, and at that time only light motorcycle helmets could meet this standard, and many cyclists refused to wear them because of their weight and lack of ventilation. To this end, Bell was the first to develop a cycling helmet that meets the CPSC standard, using ABS plastic and polystyrene as raw materials. Later, Bell used newer PVC and higher-priced polycarbonate as the shell material, which greatly reduced the weight of the helmet. Polycarbonate has also been used by Bell to this day and has become the main material of Bell cycling helmets.
 
Most Bell cycling helmets are mainly made in one piece, and the polycarbonate shell is adhered to the surface layer during the EPS foam molding stage, so that the cap shell and the cap body are more tightly bonded. EPS foam is used to absorb the impact of an accident and is also the helmet's second line of defense to protect the head. It is worth mentioning that some of Bell's high-end helmets also use progressive layering technology, the outer layer of high-density EPS is combined with the shell to form a skeleton, and the inner layer of low-density EPS ensures wearing comfort and makes the head more snug.
 
As a professional helmet manufacturer, Bell has a wide range of helmet products, most of which are known for their solid quality and low price. Bell's most recommended features are the Stratus MIPS, Draft MIPS, and Traverse MIPS with MIPS capabilities. At $150, the Stratus MIPS is the safest product available, earning a score of 81 from Consumer Reports and a 5-star safety recommendation from the Virginia Tech Helmet Lab.
 
The $35 Traverse MIPS has 25 vents for the best ventilation performance, and the snap-in brim provides some shade for practicality. Although the Draft MIPS also has 25 vents, the air duct design is not as reasonable as the Traverse MIPS, which directly leads to a slightly inferior breathability to the Traverse MIPS, however, the Draft MIPS is lighter than the Traverse MIPS and is more suitable for long rides.
 
The Draft, Reflex, and Muni helmets don't have a MIPS system, so they're priced at less, at $40. They have scored well in Consumer Reports or Virginia Tech Helmet Lab reviews, making them ideal for low-budget users. Draft's ventilation has been rated Excellent by Consumer Reports in the United States, with the best breathability; The $10 Reflex has received a 3-star Good rating in a Virginia Tech review, making it a great value for money. With its detachable brim and helmet reflective elements, the Muni is ideal for those looking for functionality.
