Have a look at Shockblaze, another Bulgarian brand who are producing some very nice bikes at fantastic prices, road and mountain bikes and just launched their 29er range.

Hargroves were bringing them in.

KTM’s def here. There’s a £5500 full suss only three miles from here in the local shop.

Radon are pretty big in Europe and are one of several German brands which are virtually unheard of in the UK (despite them being along the lines of Rose and Canyon – and now available through bike-discount IIRC) together with Bergamont, Simplon (who all do Road / CX / MTB / etc), and Rotwild (who do very good bikes apparently), Conway and probably a few niche road brands I’ve forgotten.

I’ve not seen another Rose (Road or MTB) on my travels yet, other than the one I’m sat on.
