I’m looking to buy a used bike, which would you recommend and why?

My bike got stolen years ago and havent ha one since, now I'm looking to get back in.

I want something that's easy and reliable and the ability to drive on sand/gravel so I'd probably change the tires on some of these (eventually).

These are some that I picked out from the local used market:

1. Nishiki Cross Master Pro – 370 €

2. Bianchi Via Nirone 7 – 475 €

3. Nishiki Road race 6061-T6 – 450 €

4. Motobecane Equipe pro – 400 €

5. Scott Sub Cross 50 (unused) – 399 €
