Hi all - My commuter got stolen so I'm shopping for a new one and planning ahead for when our newborn is big enough to go in the Chariot trailer. Should I be considering the added weight for towing up hills when considering a bike? I'm definitely planning to go with gears instead of the single speed I've been doing. But should I also be considering a specific touring bike vs. an old-school 12-speed? I've primarily been looking at steel framed bikes from 70s and 80s, bust starting to wonder if I need to change my priorities. Or are those old steel frames durable enough to pull kids up hills no problem?
Bikes I've been considering off Clist:
Trek 420 Touring (http://denver.craigslist.org/bik/4012656327.html)
Univega Supra Sport (http://denver.craigslist.org/bik/4003297438.html)
Viscount Aerospace (http://denver.craigslist.org/bik/4015955090.html)
Peugeot Avoriaz (http://denver.craigslist.org/bik/4018843453.html)
Bianci Campione (mostly bc it looked like a great deal, http://boulder.craigslist.org/bik/3942808767.html)
Thanks in advance! Russ
