Brompton CatEye Volt 400 light set

Brompton and CatEye have collaborated to bring you a powerful front light and mount specifically for Brompton folding bikes!

First - a short history ......

In 2016 Brompton started working with Cateye to offer some new lights, including the Volt 300 (so named as it has an output of 300 lumens) - which fitted to the front fork with a special bracket (included)

In 2018 it was updated to a brighter light output of 400 lumens - this one

Note: This is different to the CatEye VOLT 400XC - which comes with a rubber mounting bracket for attaching to the handlebars

So - what do you get .....?

This means that as a Brompton owner you now have the USB rechargeable Volt 400 front light as an option (as it's rechargeable you won't have to be constantly changing / buying batteries) - this is the front light set, though it should probably more correctly be called a front light kit

The front light set (including bracket and handlebar reflector) is suitable for any style of Brompton bike - it fits to the front forks (where the reflector was fitted) so doesn't interfere with the fold

Why does having a light that works with the fold matter?

It's easy to mount a light to the handlebars - but often the light will need to be removed for folding, or hit the forks (scratching paint - and we talk from experience here) or spokes, sometimes stopping the front catch from catching, meaning when you pick the bike up your bike the handlebars pop out of the catch

We've checked it with various bags (Brompton front luggage options) and the light is nice and visible even with a bag fitted

What is in the box?

  • 400 Lumens Cateye Volt 400 light - USB rechargeable - Brompton Branded
  • Front reflector for mounting to handlebars (as this set replaces the front reflector with your new light)
  • USB charging cable
  • Front light bracket (you will need to remove the brake caliper to fit this)
  • Installation / fitting instructions
Colour: Black (with silver / black mounting bracket)
Installation can be slightly fiddly - as the bracket installation requires undoing of the front brake calliper (nothing too serious) with a 10mm spanner
Just to show that installation is not to difficult - we made a short installation video!

Quality Product

Got one of these and the battery rear light for my wife’s Brompton. I’ve got the Shimano hun dynamo setup but these days better lights have got so good I’d probably just go for one of these. Great custom bracket holds it secured at just the right angle. Very bright and has a selection of flashing modes. It seems very well built. It’s a much lighter option than the hub dynamo system.

See the light!

Bought this because of the dedicated Brompton bracket. Fitting is easy but it helps to have an extra hand to hold everything straight for the final tightening. This light is much brighter than I expected. I tried cycling around my local unlit park and had no problem avoiding any obstacles. The bracket comes pre-bent to what seems to be the optimum angle to cover the maximum area without blinding other road users. The flash mode is brilliant for city use under streetlights. Great battery life too. No problem with the fold either. Well recommended!

    Hi is this the same light as the volt 400 xc just different mounts. Answer:
    Hi, yes this is the same (with a Brompton logo) and with a clip in mount - the XC has a rubber band type mount

    Hello, the packaging for the Cateye XC version says it should be used in conjunction with a BS6102/3 light in the UK, but I assume this isn't the case for the Brompton version. Please could you confirm? Thank you. Answer:
    All Cateye lights have that warning on the packaging - as flashing lights are only legal (by the letter of the law) if used in conjunction with a BS light

    Can I get the metallic mount separately? I have other lights that I’d like to mount using this metallic mount. Answer:
    Unfortunately the mount is not available separately - only complete with the light

    Hi, what diameter range does the handlebar reflector mount clamp fit? Answer:
    This Cateye light is designed to fit the Brompton and fits behind the front brake.

    Any word of when these might be back in stock? They seem to be completely unavailable everywhere. Have they been discontinued?What are other good options that do the same job? (Light out front not handlebar mounted) Answer:
    So sorry we do not have a firm delivery date.
