How are things going with this? any ideas working? Being tested? Being drawn? Thought of? Well, I've thought of one.
Backpacks, or any other body strap that could hold large battery cells. a side pouch, satchel, fanny pack, leg strap, anything. this would definitely improve the skate's abillity to go for long distances, and would be good for prototypes or even a starting project. then, once that became popular, companies may invest into researching making the cells fit within the skate, as well as stronger, smaller motors for them.
