DUNLOP adjustable bicycle helmet red with LED, size M

The DUNLOP adjustable bicycle helmet in red, size M, combines a streamlined shell with an integrated rear LED light to improve visibility during low-light riding. Its adjustable retention system allows a customized fit for medium head sizes, while internal padding provides basic impact comfort. The helmet is designed for urban and recreational cycling where enhanced visibility and head protection are needed.

Advantages

The helmet features an adjustable fit mechanism that secures the shell around the head and helps maintain stable positioning while riding. An integrated LED at the rear increases visibility to other road users in dawn, dusk and nighttime conditions. Lightweight construction reduces neck strain on short to medium rides, and internal pads offer immediate comfort and can be replaced for cleaning or hygiene maintenance.

• Daily urban commuting and city cycling
• Leisure and short-distance recreational rides

How to use

Place the helmet on the head so it sits level across the forehead and adjust the retention system until the helmet feels snug but not tight. Fasten and adjust the chin strap so there is minimal movement and the buckle rests comfortably under the chin. Use the LED function as instructed by the manufacturer—typically by pressing the button on the rear unit—to activate steady or flashing modes. Inspect padding and straps before each ride and replace or clean removable pads according to care guidance.

Usage recommendations

For effective protection and visibility, ensure the helmet is worn on every ride, maintain the LED battery or charging state, and replace the helmet after any significant impact or when signs of wear compromise structural integrity or fit.
