Moving to Germany

You might have to also fit reflectors, dynamo/lights etc etc to comply.

It's a bit different for road bikes.
No need for dynamo if you are below 11kg iirc. Small battery lights front and rear are enough.
Fixed bikes need front and rear brakes!

Thank you for this too. I just found a room to rent for 185 euros a month-proved much easier to organise remotely even if I'd much prefer my own space. It's in a landscape architect's office so a bit of a bonus there too as I can network a bit not to mention steal books, stationery and printing ;)

Still none the wiser on highway code and which roads can/can't be cycled on though. Will just have to play the daft forrin card for a while!

German StVO (highway code) is mental.

They have changed the laws. Battery lights are no longer reserved for sub-11 kg bicycles. Reflectors? Police tend not to be terribly stringent on enforcing reflectors but reflective sidewall tyres or even reflective rim tape do meet the requirement. The fine for missing reflectors or a bell is also relatively modest-- I think now 10 or 20 EUROs.

The law does require 2 independent working brakes-- "Fahrräder müssen 2 voneinander unabhängige Bremsen haben"-- but gives a lot of leeway into what constitutes "working". Courts have rulled that a fixed gear is a brake. This means that a single rear brake or front brake is all that is required. The law does not stipulate which but only demands redundance-- a chain or cable can, afterall, fail.
