    • Powerful, but annoying

      Vladimir (United Kingdom)
      Used for 3 to 6 months
      Whether it is to do with the design or the lens plastic on the front of the light, but there doesn't seem to be a clear distribution of the light, nor does it allow you to increase or decrease the power of the light, which is very useful for a cyclist. I am usually very happy with Decathlon products, but this time I am very disappointed.

      Thank you for your feedback regarding this bike light. I will forward this on to the product designer.

    • Disappointing, not as shown

      Emma (United Kingdom)
      Used for 1 week or less
      I bought this to replace a silicone light which I loved because it was so easy to fit and remove, even with gloves on and in the dark. I searched everywhere for one with a similar fitting, and this was the closest I could find. I was very disappointed when it arrived as the fitting is not as shown on the picture, and fitting it properly is difficult even when you can see it clearly.
    • Great product, just didn't work

      I had previously bought one of these and was so impressed that I decided to buy another one for my wife. Unfortunately after only one trip out, the light no longer charges. I have tried numerous cables and usb chargers but none works. So although mine is still going strong, I can't recommend this as the other one I bought barely worked.
      USB charging, easy mounting

      Hello Steven,

      Sorry to hear about the issue you have with your second light after the 1st one was so good you bought another. I suggest you return the faulty one for an exchange/refund.

    • Great bike light

      Madbird (United Kingdom)
      Used for More than 2 years
      Bought this light for my father after using one for over 2 years. It is a great light and now that street lights get turned off after midnight it is much needed.
    • Front Light from Decathlon

      Allan (United Kingdom)
      Used for 1 week or less
      Mid priced front bicycle light from decathlon. Have used it for night rides, it is just good enough for road bike speed. I would recommend though a greater power of front light for regular night rides at speed Good value for money but not quite good enough for a serious rider. Very easy to fit and easy to re-charge; good product
      Easy to fit, USB re-charge, value, ok brightness
      Light grade was in Lux rather than std Lumins
