They're a US brand who did sell bikes here about 2013-2016. Generally well-specced from a generic mould and quite light. I sometimes see them in youth racing.
Is it the red/black XXL one on
eBay? If so that looks decent value.
Just remember you won't get any back-up if something goes wrong with the frame. Make sure you get a spare derailleur hanger (mech hanger) as supply is probably limited. Otherwise they should have standard components.
My son has a 2013 BeOne Raw as a training bike. There are probably only 5 here in the UK from Dutch firm (Belgium-owned) and we know if something goes wrong that's it, so obtained a spare set of forks and mech hanger.
