Hi everyone, newbie here (warning)
Advice needed I think. I'm 66 in a couple of days, haven't ridden much for close to 20 years (except for exercise bike at the gym). I'm 5'8" and (Ugh) 120kg now and getting heavier daily because I haven't been to the gym for 6 months. As my name implies, I have crook knees too
I used to ride mountain bikes for many years and did quite a lot of miles back then so recently I decided I want to reacquaint myself with a real bike again.
I've been looking around and come up with this as an option to buy http://www.trekbikes.com/au/en/bikes..._series/8_5_ds

My question to all you experts out there is... would this be a good choice considering most of my riding will be on sealed roads or bike paths with just the occasional fire trail from time to time. I really do need the exercise and would like to get back on a real bike that wasn't too radical.

Help anyone?
