I can't imagine that the conditions in Brussels are that different from London and like other posters here I would worry about the size of the X2 if you are going to use it on the pavement rather than the road. The i2 works fine and you can go into lifts and through doorways through which the X2 just wouldn't fit. That by itself would be a real problem in every day use for me. I would get an i2 and if you really find that you are restricted in the size of step you can go off you can always get some turf wheels and tyres. For me it's much less of a problem to step off for a moment when getting up or down too big a step than to have to drag an X2 sideways through a doorway!
