Brussels - Where to buy good, cheap or used bikes?

Hi Warmers,

I booked a flight with Swiss Airlines, but actually will be Edelweiss the operator. So it will cost 500 E to bring my bike. After this shock I decided to buy a bike in Brussels. I saw at Decatlhon some about 250-300 E, but there is any bike store that sells good/used bikes? I will go straight from the airport to buy.

Regards,

Renato
