hmm out of the 2 bikes go with the Ventura, it has better mudguards and a rear rack which I would take as a sign that they put a bit more thought into the bike. If you're in the UK, good mudguards are gunna be worth while and a rear rack is always handy.
What is your reason for getting a folder? Might help us make better suggestions. Commuting, fitness, occasional trips to the shop, are you needing to take it on trains, buses etc. maybe you lack storage space?
