I am normally a big Decathlon fan..
I bought these without looking at the battery life..
2h & 4h.
I'm commuting 45min morning and evening.. I have to recharge every day..
I would not recommend buying this product. For such a bulky light battery life should be better.
So easy to fit to bike, no tools required, easy to recharge
Lights are bright enough. Very easy to get on and off. Inconspicuous so they are not a target for theives. However the front light seems to require a daily charge. Plus the wires supplied are to short. We don't all use a laptop to charge them.
These are a really good value set of front & rear lights. They are charged quickly (within an hour) via the supplied USB cable (nb: you will of course need a normal USB to main socket plug like the kind supplied with a mobile phone). They attach to the bike via a strong stretch rubber connector - so no fiddling around with screw connectors. The brightness of both lights are really good ...can't say how long the charge lasts as I've only used them for an hour at a time but this seems pretty good so far. Highly recommended..
