The FLUX is a waterproof, 29-litre rucksack that also happens to be the largest bicycle rear light in the world.
Urban cyclists have taken to attaching lights to their bags, but the FLUX takes the idea to a new level. Light from a bank of LEDs is dispersed by a fibre optic panel measuring 30 cm by 10 cm. The USB-rechargeable light can be set to constant or flashing mode and is easily removed for when cleaning the bag.
With a courier-style fold top, 1000 denier nylon outer and vinyl tarpaulin interior, the FLUX promises to be absolutely waterproof.

I’ve seen the light – illuminated cycle clothing
Illuminated clothing and accessories is a growth area in cycle lighting. The Aura is a nylon webbing belt with a flexible LED and fibre optic lighting system embedded within. It can be set to emit a constant glow, slow pulse or a strobing flash.
An illuminated belt means you need never be without a rear light

Wallpaper swatches! I deliver samples by bike if my customers are nearby.
Eric Ludlow
My sense of humour 😉
Luna
I would definitely keep my sketchbooks safe and dry in the Flux bag. Nothing better than cycling around London looking for interesting people to draw 🙂
Sarah
Books
Clare
I would keep my pet ferret in the bag, he hates getting rained on in my basket.
Tim
I’d store my Gremlin in it, because one is hard enough to look after, let alone 100…
Greg
my goldfish
Sarah Lou
roasted peanuts 🙂
Claire
A spare change of clothes because you’re always just a few moments away from a shower when cycling in London!
L Woodman
Fantastic idea
Neil Woolford
The extra shopping that won’t fit in the panniers after a trip to Lidl.
giuseppe
I’d keep the change of clothes dry in this big rear light!
Grace
My laptop, paperwork, headphones, and camera. Because I have a regular kind of life that needs to be lit up by the Flux! Maybe once I have it I’ll become the kind of cool cyclist who pedals around carrying goldfish, designer wallpaper, and peanuts.
Joe
Dog. No more wet dog smell. Awesome.
Richard
My baby daughter – only kidding, however perhaps the dog….
Steven
I’d keep my shopping in the bag…And my life outside it.

Joel Halligan
I would keep my lunch dry. Nowt worse that a wet lunch.
Nigel Searle
My dry suit of course!
Johnee
It would be just the thing for those dark wet December days we have in W Scotland. Particularly for one of those cyclists who seem to try to make themselves invisible by riding a black bike, with black tyres, dressed in black and wearing a back helmet.
lucy
my clothes – nothing worse after getting soaked to not have dry clothes.
Stuart Lamb
I’d probably try and get into the bag myself and get someone else to cycle me around
James Beasley
I’d put my pants in the bag, nothing worse that sitting in wet pants.
Raf
ah this will help avoid mishaps i’ve had with the rain when taking home pupils’ books to mark : )

It would be perfect for carrying music to and from choir rehearsals.
Peter Chisnall
What a bright idea!
Peter Clark
Blackberry, ihone, keys, underwear to change into, wallet and assorted other detritus!
JLS
I would keep my cycling waterproofs nice and dry in this bag as I always seem to get caught out in passing showers whilt on my trusty treader. At least this amazing bag would save my embarrassment!
Mark B
I’d keep my waterproofs in there so they’re dry and ready when I need them.
terence riley
I think that this is an excellent idea and product, but I also think that there should be a choice of colour, perhaps yellow, which can be easily seen by other road users in the daytime.

Cath
Perfect for my essentials of life….food and flask of coffee…

Spare socks – wearing wet ones all day….horrible

The future is looking a lot brighter!!….

I’m a cycle training instructor, so what I’d keep dry is: money, keys, phone, a snack, forms for trainees to complete, risk assessment, cones, spare gloves, ankle straps, warm gloves, waterproofs, (though I’d be wearing them if it was raining).
Francis Voon
My sandwiches!
Hilary Robinson
Ideal for a packed lunch …
John aka TheCyclist
I would keep everything in the flux bag except my bicycle and myself. :- )

A great alternative way one can be seen. I would carry my bike tool kit, cloths, biccies, maps, waterproof trousers just in case and bird food for the ducks on the local pond.
Andy
I would keep my spares in the bag, even better that I will be more visible to other road users! Fab idea
Iain
My mojo!
