^^^Do not do that.^^^
C'mon Oscar. I'm sure he wants his transmission to last a little while.
Put the trike in third gear. Pick it up from the grab bar and walk it forward as fast as you can. Drop it on the wheels when you're going as fast as you can and push down on the grab bar while continuing to keep it going forward. Do this where there isn't a whole lot of things around for the trike to take off into should it get away from you.
