This scooter uses a gearbox of some sort, which is a 5:1 ratio, running a similar overall ratio to a tami/viza scooter, except this scooter has 12in wheels
I am just taking a guess here, but I think the final drive is 8 to a 16 (2:1) giving an overall ratio of 10:1
The deck is wooden, with sand glued on to it for grip.
The scooter frame used for this project is a NEXT brand scooter. Apparently they are rather cheap to buy, but are not cheap on quality.
