Hey guys! I'm new to the forum and this will be my first post. After checking the sticky "Advice for New Commuters" thread I didn't find anything for my particular case. After a co-worker turned me on to the idea of commuting I've decided to start an investment in a bike. My commute will be 18 miles to work and about 10 miles to school. I was first considering a BMX bike (stupid of me,) then I looked into MTBs (Haro Shift R1, Haro Escape, Gary Fisher Mullet,) but now I'm looking into other bikes, such as the Trek SU 2.0 and the Gary Fisher Cronus. I have a Bike Barn shop directly down the street from me, but I'm a little hesitant to walk in without the intent of buying immediately, as there will most likely be loads of sales pressure. My price range will probably be $700, but I'm willing to shell out a little more. How do you think a Gary Fisher Mullet will compare to the Trek SU 2.0 or the Gary Fisher Cronus? I'm looking for something with disc brakes and multiple speeds. Storage need not apply. I work from 10 PM to 6 AM, so I'll definitely need to add on lights and what not. I'm 19 years old, but I'm a bit out of shape, working security will do that to you! But it's even more motivation to commute! I'm taking baby steps and riding a few days a week after work on my brother's pawn shop bike until I'm a little more confident with my physical ability. Thanks so much for your time and I look forward to future communication with all of you!
