Kind of what Segways would be if they were more dangerous: ie fun.
Step 1: Tear your electric zap scooter to pieces.
Step 2: Base for skateboard trucks.
Step 3: Hose clamps
Step 4: Select and prepare skateboard trucks
nice ones can be found at:
Step 5: 3 pairs trucks
these are 100mm diameter skooter or rollerblade wheels. bigger diameter means better on bumps and rough streets. thinner means less rolling resistance and faster.
Step 6: Make stand offs.
Step 7: Rocker and roller.
Step 8: Apply the skateboard trucks.
i used 10-24 bolts and nuts, the metric skating ones are too obscure and expensive when you are in america...
Yay the metric system!
Step 10: Take it out and test it.
Step 11: The aftermath
the trucks on the outside should have been angled inward.
apart from that it had all the sliding smooth, vaguely dangerous feeling we had hoped for.
the wood however will ultimately need to be replace by a welded bar or something similar. you can see here how it suffered (though we did absolutely thrash it for a good few hours before this happened).
