I would also highly recommend Decathlon. Their road bikes mountain bikes and hybrids are incredible value for money (I build bikes and can't do them for the same price/quality ratio using trade prices!). The Vermont one is OK, pretty low end spec though and will be quite heavy. If you're only going on roads and a minimal amount of tracks etc then as already said you're probably better off without suspension. However, I would recommend getting something with a carbon front fork, the amount of road "buzz" it'll neutralise will be very noticeable and it'll make the bike more responsive and lighter for little extra cash.
However, if you are thinking of following any of the
Camino Frances cycle route, then you might want to think again as large parts are off road (although there may be an alternative) and a good lightweight mountain bike (with at least front suspension) would be better. I don't know about other routes.
Personally I would go to a Decathlon store, tell them what you're hoping to do and try a few out for size/riding style etc. You can ride them around the store to try out and the mechanics usually know their stuff. They'll also customise them too, such as adding pannier racks or mud guards or changing pedals or seat posts etc. And also buy any shoes/panniers/clothing/helmet/pump/puncture kit whilst in store too.
No I don't work for them (if you were in the UK obviously recommend my services) but I would highly recommend getting yourself to France and just find the nearest Decathlon store to your destination and take it from there.
Hope that helps.
