Hi Gus,

It is limited to 5MPH via gearing. As a result, though, it has an
incredible amount of torque (about 150 foot-lbs) and can climb a very
steep incline.

It was custom designed for Jon's daughter Katie and with lots of
safety in mind. She's a pretty girly girl so I'm not sure she wanted
to go very fast anyway. However, I think safety was the main reason
for keeping the speed low. Since it is really meant to drive around on
a beach, over rough and loose sand, and among people, there are other
limits on speed anyway.

Sean
