Anything recommended that is cheap?
Take it these are not very good? http://www.amazon.co.uk/Streetwize-SWPW-Portable-Pressure-Washer/dp/B00GOLJLLI#customerReviews
Struggling transporting a filthy bike in the back of my mondeo!
It's a mondeo 🙂 that's it's whole purpose in life.
Get an old Duvet and stuff it inside.
A search for "portable bike washer" gives a few hits - the Dirt Worker carries enough water to get most of the muck off two bikes.
I've got this

recommended
I got a laser tools one for about £30 which doesnt seem to exist anymore except on one website fore £140!
I can see the appeal of the re-chargeable self contained ones, but it does the job and I usualy just leave a 25l jerry can of water in the rear footwell which will do a weeks worth of rinses.
The only thing better would be a bike rack and the cost a dirtworker divided into 50p's for the petrol station jetwash. The 'hot soap' setting is usualy more like hosepipe pressure and de-frosts frozen mud to boot!
mobi portable washer is good.
I've got exactly the one as in the link! Used it about 5 times already. I used to use two buckets (one soapy water, second with clean to wash off) with brushes . I wash my bike on a car park, which is too far from home to use a hose. So carrying all the stuff up there and back is quite an exercise... 8) What can I say - this things is brilliant for me!
All I need now is that water pump filled with clean water and an old muc-off spray bottle filled with fairy solution or some bike cleaner if I have any. And brushes. Remove move of the cr*p with a brush first, then wash the bike.
The pressure this "machine" creates is sufficient enough for the job. Feels a bit flimsy to be honest, but it works well, doesn't leak and simply makes my life a bit simpler 
I have the Airace and it is good and has better pressure than the mobi - and I think the fitments are better judging by reviews.
I use a portable jump stat battery thingy as well - as I have it anyway for if the battery on my little used alfa gets low :
I have the original yellow Dirt Worker and I'd recommend getting something similar rather than a glorified plant sprayer.
The pressure is greater and more consistent so you can spend more time washing your bike rather than pumping the canister up whilst you're freezing your nads off in a car park somewhere
Don't bother with the one in the link, spend a little more, and get something like the Mobi, I got mine for £80 it's spot on a bit of that muc off pink pre wash spray and the bike comes up a treat.
I use one of these:

I got an old shower head, sawed the rose off it and replaced it with an unused nozzle of a silicone tube. It's not the highest pressure device, but it does work and certainly doesn't threaten to force water into any seals! The beauty of it is that with the device so handy after the end of the ride, the mud is still wet and therefore easy to remove.
I use a Nomad;

It uses the same batteries the Ryobi One+ system - I bought a 'bare' washer from them and use my drill batteries with it.
Used with a brush the hand pump version or the camping shower type devices are totally fine. The water helps to soften any dried on mud but the brush does all work so you don't actually need a high pressure water stream. I find I can easily wash one very filthy bike using 5 litres water or give two bikes a rough clean.
If you just want to stand pointing a hose and let the water jet blast the mud off then the more powerful Nomad washers will be suitable but will also require more water.
