That's no road bike!.

The thing is, it's more dangerous to go very fast. If he rides only by himself, a slow bike can be used by a "serious rider... for endurance and speed". If the same effort results in a lower speed, that could be a good thing. There maybe opportunities for amateurs to race time trials in Belgium. My guess is most of the entry level racing is crits, so I'd suggest a bike that is legal for mass start events.

I really don't see the reason a recreational/fitness rider would use a machine such as this one. The handling of a TT bike compared to a road bike is compromised in pursuit of speed. Why increase your risk to beat the wind when you aren't in a competition?
