I'm just getting back into moutain bike riding. I'm considering buying a Motobecane with front fork suspension only. What's the main difference between front suspension and full-suspension bikes? Do I need a full-suspension bike. I anticipate doiing mostly street and light to medium trail riding. I cannot see myself doing too much crazy downhill stuff. Can anybody advise? Also, does anybody have opinions on Motobecane as a manufacturer / bike package producer?
