In the last few months, a number of retailers and bike brands have announced plans to remove their existing helmet sizes.
The latest of these is the British apparel company Jet Life, which says it will no longer offer a standard size 28 in 2018, but instead will change the size of its popular Sport-Cycle model, which is currently available in a range of sizes ranging from 32 to 48.
The new model, meanwhile, will remain a standard 28 for 2018.
“The UK is the biggest market for helmets in Europe, and the UK’s large share of helmet sales is a key driver of helmet demand in the UK,” Jet Life’s chief executive officer, John O’Connor, said in a statement.
“Our customers will be able to choose the right fit, the best fit and the best quality for their riding, and we want to be there for them.”
O’Connor added that the company has “a long-standing commitment to providing our customers with quality products at affordable prices.”
In a statement, the US-based bike brand, Bike Nation, which operates on the same model platform as Jet Life and Bike Nation Sport, said it would also be removing the standard 28 size from 2018.
The company said it will offer an expanded range of fit options for consumers.
“Bike Nation’s commitment to creating and selling a range from the latest in technology and innovation, to quality apparel, to high performance bike gear, will continue in 2018,” the statement said.
Bike Nation’s announcement comes on the heels of another British company, Cycle World, announcing that it would stop offering the standard size of 28 in 2019.
Bike World said that it is making a “commitment to improving the fit and comfort of our customers,” while adding that it will be introducing a 28+ option.
The move comes amid a broader debate about bike helmet safety and safety standards.
According to a 2017 study by the American Academy of Pediatrics (AAP), helmets have a high rate of injury, particularly for children and adolescents.
The study found that more than half of helmet injuries occur in youth, and that the injury rate is significantly higher in children who wear helmets than in adults.
According, the study, the American Association of Pediatrics issued a report last year saying that helmets should be designed for kids under five years old, and should not be designed to fit older children and teens.
The AAP said that “there is insufficient data to determine whether the standard of safety for children under 5 years old is adequate for their age, and if helmets should continue to be recommended.”
According to the AAP, helmet manufacturers must make helmets available to kids with a “threshold age” of 15 years old.
In the study published in Pediatrics in 2015, researchers found that the average head circumference of children wearing helmets was smaller than that of those without helmets, and more than 80 per cent of the children with head injuries had head injuries that were caused by head injuries.
In addition, researchers observed that most of the helmets that were tested had “slightly less padding than the rest of the helmet,” and that more padding was needed for children with smaller heads.
The researchers concluded that the “adequate” level of padding needed for younger children to wear a helmet was “between 2 and 5mm.”
