The short answer

  • CPSC warned consumers in December 2025 that Duyue2 adult bike helmets, sold on Shein, violate the mandatory federal bicycle helmet standard, 16 CFR Part 1203.
  • The manufacturer, Shenzhen Duyue E-Commerce Co., has not agreed to a recall or remedy — CPSC's recommendation is to stop using the helmets immediately, cut the straps, and dispose of them.
  • A separate June 2026 warning covers CARBO Model X and S folding e-bikes for failing mandatory reflector requirements, with the Model X also lacking a required chain guard.
  • The mandatory helmet standard requires at least 105 degrees of peripheral vision per side, strap stretch limited to 1.2 inches, and peak impact acceleration capped at 300g, along with specific labeling.

CPSC has issued public warnings — not recalls — about two pieces of outdoor gear this year: Duyue2 bike helmets sold on Shein, and CARBO folding e-bikes. In both cases, the agency says the manufacturer hasn't agreed to fix or take back the product, which is why a warning replaces the usual recall notice.

The helmet warning

CPSC issued its warning on December 11, 2025, for Duyue2 adult bike helmets, sold on Shein.com from April through November 2025, priced between $14 and $44, with about 100 units sold. The agency says the helmets violate the "impact attenuation, retention system, positional stability, certification and labeling requirements" of the mandatory bicycle helmet standard. The manufacturer, Shenzhen Duyue E-Commerce Co. in China, has not agreed to a recall. CPSC's recommendation: stop using the helmets immediately, cut the straps, and dispose of them.

What the mandatory standard actually requires

The federal standard, 16 CFR Part 1203, requires bike helmets sold in the U.S. to provide at least 105 degrees of peripheral vision per side, limit strap stretch to 1.2 inches, cap peak impact acceleration at 300g, and carry specific warning labels, a certification statement, and manufacturer contact information.

The e-bike warning

Separately, CPSC issued a warning on June 11, 2026 for CARBO Model X and Model S folding e-bikes, made by Veco Electric Bicycle Inc. and sold through Ridecarbo.com and Greenpath Electric Bikes. About 480 units, priced $2,200 to $2,900, were cited for failing mandatory reflector requirements; the Model X was also cited for lacking a required chain guard.

How to check your own gear

  1. Look for a CPSC-compliant certification label inside the helmet, along with manufacturer contact information
  2. Check that side straps don't stretch more than about an inch under firm pull
  3. Confirm the helmet provides a wide, unobstructed field of side vision
  4. For e-bikes, verify functioning reflectors are installed as required and that a chain guard is present if the model calls for one
  5. If you bought either product through the listed retailers in the affected windows, stop using it and check CPSC.gov for the latest guidance
