I was able to ride an BikeE2 solo perfectly as soon as I started pedaling. That was on a sidewalk around the Oregon State campus. The slow speed handling was incredible. (It might have helped that I was already an experienced recumbent rider.) I saw several on that year's Bridge Pedal, ridden by company employees and family. One team appeared to be a couple kids, maybe 10 and 6 years old. They looked like they were having a ton of fun.
