Project RazEr A.K.A “Snuffles Reloaded”
As a followup to Snuffles The First, I have actually decided to down-engineer something (can you believe it?) while adding tweaks and more advanced technologies. This rebuild is intended as a testing bed for small-EV technologies as well as my way of getting around town faster.
The design has exactly two moving parts – the front wheel and the rear wheel. Propulsion is provided by a custom-built in-wheel electric motor (a hub motor) that is mounted inside the rear wheel. No mechanical parts protrude or rotate externally, and the standard fender friction brake still works.
Batteries are housed in an aluminum frame extension under the scooter body.
Once my own version works reliably, an extension of the project is the creation of a (near) drop-in conversion kit for anyone else who happens to want a small zippy electric scooter.
