The ST stands for "Step Through". This is the easiest boarding of Rans Crank Forward bikes which have been big sellers for bikes@vienna for the last two years.
These are light and comfortable bikes. The seats are very generous (large). People appreciate that the Crank Forward style allows them to stay seated when they come to a stop and to be able to place their feet flat on the ground.
This combination of comfort and feeling of enhanced control has made the Fusion popular with individuals returning to cycling. This easy to step through model should have further appeal for returning cyclists. For more information go to http://www.ransbikes.com/FusionST09.htm. For a test ride, I invite you to come to bikes@vienna located at 128A Church Street, NW in Vienna, VA 22180
