About 1,950 black Vevor BMX bicycles are being recalled in the United States because they were sold without a chain guard, the shield that keeps a trouser leg or lace from being pulled into the drive chain. Sanven Technology Ltd. of Rancho Cucamonga, California, imported the 20-inch and 24-inch freestyle bikes, which were made in China.

The Consumer Product Safety Commission announced the action on Nov. 5 as recall number 27-073. No injuries or incidents have been reported, and the fix is a free guard that owners fit themselves.
Models SS24001 and SS24002 and the missing guard
According to the commission’s notice, the recalled bikes are black with the Vevor logo across the downtube, and the model number, SS24001 or SS24002, is printed on the packaging. Loose clothing “can get entrapped in the chain drive,” the notice says, which creates a risk of serious injury or death from a crash. The bikes also fail to meet federal labeling requirements, a second violation that the notice mentions only in passing. Vevor sold them at its stores nationwide and on vevor.com from October 2024 through April 2026 for $152 to $188. That is about 19 months of sales, and the commission reports no incident in that span. Trade coverage by Bicycle Retailer repeats the same model numbers and sales window.
Federal chain-guard rules for single-speed bicycles
The requirement being cited is old. The commission’s bicycle business guidance says a bike with a single front sprocket and a single rear sprocket needs a guard over the top of the chain and at least 90 percent of the front sprocket’s contact area, running back to within 3.2 inches of the rear axle centerline. A single-gear BMX bike is the kind of machine that provision describes. The text of 16 CFR 1512.9 adds a rod-entrapment check using a 9.4 millimeter rod, about three-eighths of an inch. A bike that omits the guard has nothing to put through that test.
Bicycle chain guards have been federal law for a long time. The commission announced its first mandatory bicycle regulations on July 3, 1974, with an effective date of Jan. 1, 1975, and that release described chain guards for bikes that are not freewheeling. A guard missing from a bike sold in 2024 or 2025 therefore runs against a rule older than most of the people who will ride it. The same guidance lists the rest of the mandatory package, from front and rear brakes to reflectors, tire-pressure markings and a manual. Sellers who want the plain-language version can start at the agency’s bicycle FAQ page, which lists chain and chain-guard requirements among its questions.
The labeling finding is a quieter matter. A permanent label must show the manufacturer or private labeler and the month and year of manufacture, and a bike sold in pieces must carry assembly information so that an adult of normal ability can put it together. The commission’s notice does not say which of those items the Vevor bikes lacked, only that they do not meet labeling requirements, so the exact gap is left open. Beyond labels, the guidance requires non-sidewalk bikes to complete a 4-mile ride and a cleated-course test and to tilt 25 degrees without any part other than the tires touching the ground, so a bike can fail a regulation in several different ways.
For a parent or a used-bike buyer, the practical check is quick. Look for model number SS24001 or SS24002 on the packaging, a black frame with the Vevor logo on the downtube, and a wheel size of 20 or 24 inches. Then look at the chain: the federal rule calls for a guard that covers the top strand and runs back to within 3.2 inches of the rear axle, so a bare chain on a single-speed bike like this one is the defect itself.
Chain-guard violations are not confined to cheap BMX bikes. In June the commission warned consumers about 480 CARBO electric bicycles priced at $2,200 to $2,900, citing failed reflector requirements and a model without protective chain guards, and the maker had not agreed to offer an acceptable remedy. The Vevor case differs in outcome: the importer stepped forward with a repair.
The free repair kit and how owners claim it
Sanven’s remedy is a repair, not a refund. Owners are told to stop riding the bike immediately and contact the company for a free kit containing a chain guard, step-by-step self-installation tutorials and after-sales email support. Nothing in the notice calls for a dealer visit or for the bike to be shipped, which keeps the cost to owners at the time it takes to bolt a guard onto the frame. Vevor’s recall page spells out the request. Riders email [email protected] with a full name, shipping address, a photo of the bike showing the Vevor logo and, if available, a receipt. After verification the kit ships, and once the guard is installed the bike can go back into use.
The unresolved piece is time. Neither the commission nor Vevor says how long the kit takes to arrive, or how many of the 1,950 owners have already asked for one.
