Gnomish Space Marines Biker Scout Upgrades?

As I'm working developing units for the Gnomish Space Marines, trying to differentiate between organized biker scout units and the more rag-tag biker units known to roam the plains.  

Adding to my choices for organized scouts who fit within a combined arms mentality, I present the Houran Enforcer Monowheel Squad from Gydran Studio.  

These look clean, look high-tech enough for GSM Scout "regulars", and I dare day at £30 ($39 US), I only have to worry about S&H from the UK.
