New York City Mayor Zohran Mamdani has become known for many things: urban affordability, universal child care, dimples, and most recently, bike safety. After he was spotted several times biking without a helmet, Mamdani received some jovial, if not earnest, criticisms from his constituents. (You can learn more from experts who say a properly performing helmet could very well be the difference between life and death in previous HuffPost coverage.)“You’re right. I’ve got to do better. Safety first, NYC,” the mayor stated in an official video posted to his Instagram. In that same video, Mamdani can be seen unboxing a new helmet. Though it’s impossible to tell what brand or make it is — nor did Mamdani endorse a specific brand or style — we asked resident biking expert and HuffPost trends director Buck Wolf for some general bike helmet suggestions.“I think it’s important to buy a new helmet every year, but I like the cheaper ones,” said Wolf, who crossed the country on a bike in 1985 and continues to bike 4,000 to 5,000 miles a year. “I would recommend against the $300 helmets.”Buck, who says he’s currently wearing a $25 helmet from Costco, said he also prefers options without a visor and instead opts for a bike cap, which provides sun protection. Up ahead, we rounded up six under-$35 bike helmets so you can bike safely or replace the one you already have since they do expire! But before you take your new helmet out for a spin, see what experts told us about making sure it fits and is worn correctly.AmazonAn adult bike helmet with a detachable sun visorExperts previously told HuffPost that your bike helmet should be CPSC-certified (Consumer Product Safety Commission) and have a liner made of EPS (expanded polystyrene), a crushable foam layer that absorbs impact and reduces skull fracture risk.
