50k but what bicycle?

[Greyson V]

A good friend and I have volunteered to bike 36 miles or 50k for charity. We work out, however neither one of us are bikers. We have been training for this bike tour, yet we're clueless when it comes to buying these bikes. Originally we were going to do some sweet vintage bikes. We have since abandoned that idea for fear that using said bikes could make this event harder. We're training really hard for this thing! So my question is to you bike enthusiasts out there. I'm calling all Lance Armstrongs! What kind of bikes should we be using for this event? We need the best yet under 5 grand bike out there to help us on this journey. Also, keep in mind, though we take the cause very seriously, we're not trying to look like pro bikers, I'd rather not use something Lance would use but instead a good appropriate bike that I can attach streamers to. =) Thanks!
