When it comes to keeping yourself safe as you cycle, you really can’t put a price on shielding yourself properly. Protective equipment may never actively ‘save’ you, but it only takes one faulty brake, one errant driver, one commute without LED brake lights to saddle you with a lifetime of wishing you had erred on the side of caution.
Rear bike lights are a case in point. You might think your reflector can do a good enough job of keeping yourself seen to pedestrians and motorists, but can you really afford to take that chance?
Let’s take a look at why rear bike lights and bicycle brake lights are so pivotal to a cyclist’s setup, before looking at six of the best USB rear bike lights currently on the market at affordable prices.
Importance of Rear Bike Lights
Well, first off, it’s a legal requirement to have a bicycle rear light when cycling in the dark, so there’s that for a start. Even then, you should try and go by a ‘brighter, the better’ rule – this will help stamp out the ‘I couldn’t see you’ excuse on the driver’s part in the event of an accident.
Plus, in particularly dark areas, rear bike lights will make it easier for you to navigate your way around curbs or other bumps in the road – you don’t want to be cycling along, minding your own business, only to be sent flying forward by a unsighted divot or for a pothole you never noticed to send you crashing.
If possible, go for flashing bike lights, too. Standard red or white lights are certainly better than nothing but a constantly blinking light is far more likely to grab a driver’s attention in an instant.
So, it’s vitally important to set yourself up with a good, reliable rear bike light as you set off on your travels – both to see, and to be seen.
Top 3: USB Rechargeable Rear Bike Lights
Best Rechargeable Rear Bike Lights
This rear light from Knog boasts interchangeable straps as well one CREE LED light and three extremely bright standard LEDs, which operate between five different light modes including a flashing function.
One of the best LED bicycle lights in terms of value for money, it’s waterproof, dustproof, will keep you visible on your bike up to 1000 metres away, and its USB-rechargeable battery takes no longer than five hours to fully charge up.
Depending on the light mode you use, its run time can last up to an impressive 20 hours, too.
A slightly more expensive 44 Peak Lumens model from Knog, this again is waterproof, with a reflective face and five different lighting modes to choose from.
Between this red design and the R70, there isn’t much to split these two fine USB-rechargeable bike lights, in truth. Again, it will make you seen for up to 1000 metres, and its interchangeable straps make it compatible with a host of different bike types.
