My folding bikes are step through. The folding bike design would be impossible with the top bar in place which is why the step through became necessary. There is some flex in the frame of a folding bike but it's really a non issue since this cycle is used for transport or traveling and not racing. Want to see a $2000.00 dollar step through bike? http://www.pbwbikes.com/foldroad.html

I rode a step through Breezer www.breezerbikes.com last week. It was the "Uptown - UFrame" step though city bike. To be totally honest, I didn't feel ANY flex and the bike was solid. It's a beautiful bike with chain guard, dynamo lights, fenders and rack. It's a complete commuter. If I didn't purchase my Bianchi Milano, this bike would be in my stable. For a town bike, the step through is safer than a diamond frame especially for men. (if you know what I mean!)

Someone above mentioned theft as a factor in getting a step through bike. I totally agree. I commute with a step through folding bike and no one touches it. Seriously. My step through folding bike costs $330.00 yet the theives would rather steal a $99.00 Huffy mountain bike. My friend at the station parks his Cannondale hybrid with THREE CHAINS and people always steal his asscessories and try to rob his bike.
