I have a hub motor with a 16" tire on it that I am considering putting on this scooter, but it will raise the back end up a fair bit and it's only 1000 watts. The existing outrunner is almost that powerful so the hub wont really add anything to the kick scooter.

Re that "Dray" design? I said in that Dray thread "The front hub ain't exactly as pictured (that's a Nine Continent) but actually a cast 16" made by Crystalyte years ago." And cast wheel vs spokes? No idea who might sell such a thing these days.
Hehe... "Only" 1000 watts. Zat continuous or peak power outputs? All day long 1000W? Or just temp... Running the Currie at 400W (I think it was) could handle me (weight) plus one passenger.
LockH wrote:Cool. So... "stronger" = higher wattage rating = drains batteries faster?
Also, you realize the riders body position (standing up on the Currie) equates to the proverbial "broad side of a barn door"?
Although "not that fast" at about 20+km/h... with a strong headwind added... I could actually sit down on the deck while underway (still able to reach the handlebars) and the speed increase was noticeable! Sit down, speed up. Stand up, slow down.
More about aerodynamics here:
So, the shape of the Dray design wasn't just to add cargo capacity... it was also to help provide some "windscreen" shape to the scoot! Thought about adding any sort of a windscreen to your Currie? (It's all about getting more range per charge/lowering watt-hours consumed per mile/making the batteries last longer before final recycling/replacement!)
LockH wrote:Hehe... I'd forgotten about that delrin block... Yeah. Any "noise" bad ie resistance ie higher energy consumption per mile. Other than extending the rear fender w/a piece of plastic, really did zero to fix/improve. (Was having too much fun.) So for me it was mostly just an education in how to conserve energy over distances. Coast to stops, kick to start, etc. Cost of replacement batteries (2x 12V 10Ah batts) was too cheap (versus savings eg pubic transit). Again. Just having too much fun.
