Strap Breaks Again

The Lighting Is Good, However Rated It 2 stars as this was my second light and the strap Breaks less than 1 week of usage. Will not recommend as I saw in other reviews were complaining the same thing.

Hi Tan

Thank you for your kind review. It was unfortunate you do not have a pleasant experience. This Front Light is supposed to be the best in the range but unfortunately it is not. I have had better experience with lights from Moon Sports

Not at all recommended

I have purchased the Brain 500 from decathlon on 4th jan 2020. It's gear is getting slipped every time . On the time if purchase the same was reported, but the do some tuning and given the cycle. 2nd day the same complaint has been reported and took the product again to decathlon and they have done some fine tuning and returned back the product. But today, when I go for the ride, the gear slipping has happened several times. I have complaind at the decathlon store and they have arranged an auto guy to take the cycle to repair it again. I'm fedup with this product. The funniest part is that I'm still using Firefox 21 gear cycle for the last 3 years without any problems.

So so..

It lights up a small portion ahead of you in a strange rectangular area where it is positioned to focus on the road..The brightness is also very average..Was expecting it to be much brighter but would definitely not advise for trail riding..

Dear Adrian,

Thank you for taking time out to review our product. I regret that our bike light did not meet your expectations. The Front Light 900 is certified for road cycling use as per French and German accreditation. It produces an output of 20 Lux and has a lens that focus into a narrow beam as it is designed for road cycling.

You might want to consider the Front Light 920. It produces an output of 11 Lux and results in a wide, diffused beam. It will help you to see the road in front, the verge and the surrounding area. This light is recommended for trail riding and urban use.

Hope this helps. Thank you.

Really expensive for what it is

Doesn't give out a huge amount of light, certainly not for the needs of a cyclist. Needs daily charging (I use 20 minutes per day). The rubber ring (to attach to handlebar) doesn't feel robust - I'm pretty sure this will snap before too long Very expensive for what it is - a poor torch. Another very disappointing product from Decathlon

Thank you for giving your feedback regarding this light.
The light is rated to 20 LUX and is designed to be seen with and will give light on the road for a distance of around 10 meters. Ideal for use in well lit urban areas.
However, it is worrying that this only last 20 minutes between charges. It should last 2 hours. If this is the case, there may be a fault with the unit. Please return it to us for a refund or an exchange.
Should you wish for something more powerful, I would heartily recommend the following model:

Rubber strap not durable

The option to recharge the lamp is very quite convenient. I was finding it very useful for my early morning rides until today when the rubber strap tore apart suddenly. The lamp as such is very sturdy and still functioning, but the unit as such is practically useless now.


Very good and powerful light. USB charging option let you save money on batteries. But I am confused about the lasting of the rubber strap, which holds the light to the handle.

Worst light I have seen

This is the worst product I got from decathlon,its rubber is already showing sign of wear off and light battery also doesn't last good.

Great lighting but flimsy rubber strap

The lighting is good for very dark riding. However only after a month of usage, the rubber strap band breaks. If only the rubber strap is thicker/wider.

Hi Chuan Kai,

Thank you for sending your feedback on the FL 900 LED Front Bike Light. We will feedback to production on the durability of the light mount. If you wish to have your light exchanged or refunded, you may do so at any of our stores with a bicycle department.

Worst light ever

I had bought lights form decathlon before.. and other brands as well but this front light is the worst ... A it's very difficult to put it on ...and hard to remove too. for charging ... The rubber will have wear and tear and can easily snap ... and mine is already showing signs of bits comming off by the pulling and snapping it to the grove ... And it at all it breaks with the pull the store is not be held responsible beacuse of the wear and tear policy that they have ... This is a design fault and not wear and tear ...

Hello Patrick,

Strap of Poor quality

If you are riding approx 20K/h, then light is OK..if more than..then think twice..however bought only 2 mths back & rubber strap is gone..only mounted & recharges 5 times..suggesting a stiff mounting unit.

It’s really bright

It’s gives 10ft of good visibility of road and I believe ppl on road coming against us will be able to see the light from a far distance as well. Easy to assemble and disassemble for charging. Handy to carry
