My wife and I are intrested in getting into cycling. Im 59 and she is 52 both in decent shape walking 3.5 a day etc. I'm confused about the types of bikes we should get. Right now we are shopping on e-bay? good or what, but I'm more concerned with terms gears and all the terms. I'm 5'10 and she is 5'5. Does anyone have any suggestions as to which direction we should take. I don't want to drop a lot of money on something we might not enjoy.
