Joe;
I currently have four electric bikes and one old Mongoose Ascent mountain bike. The four electric bikes are: A folding bike with 26 x 1.95 mild mountain bike tires, 8-fun 350 watt hub motor, internal 36 volt, 10.2 amp battery, much the same motor and battery as the Sonder's bike, but 10 pounds lighter. Also, three light weight, high geared, single speed, bikes (as shown in the photo). 28 x 700 c wheels, 30 pounds.
My thinking is going towards lower powered, geared hub motors. I have two with pedal assist only, a 180 watt hub motor and a 24 volt battery. They get you up to speed and up hills much like a geared bike would, but much faster and easier. Very much fun to ride.
One bike has a 200 watt hub motor, a 36 volt, 10.2 amp Samsung battery, (the same battery Sonders is using) and a thumb throttle. That bike weighs 34 pounds, This is one amazing bike. It was stolen with the intent to copy it and sell it on Indiegogo. I'm certain that the thief, a skate board shop, can't copy it because they don't understand the thinking that created it. An earth scorching Yelp review of the people involved got my bike back. It's a long, and interesting story, but a story for another time and venue.
I think I know the specs of the Sonder's bike, and I'm fairly certain of the cost. I am skeptical that they can actually deliver bikes for the price charged, as I am certain that the specs they give are far from accurate.
Sonder's did a great job of something, but I'm sure we disagree about what that was. I'd say it was marketing.
I love riding the lower powered bikes because they ride like a good bike with the switch turned off. With the switch on, the motor gets you up to speed and up hills. I over ride the top speed, so the range is hard for me to determine, I think this is a great combination. It turns out that you don't really need a lot of power.
Oh, and I had another amazing bike, 250 watt hub motor, 36 volt, 10.2 amp, in the style of the folding bike I now have. It did 22 mph, had a range of 27, w/throttle only at top speed. Did 44 miles on power level #2, 14-16 mph. That bike was stolen out of a garage. The build quality was lacking, but the specs were amazing. I suspect a little over volting because of the speed. I liked that bike a lot.
But I like all my bikes, which is why I keep adding to the fleet. The folding bikes fit in the trunk of my Honda Civic, and in the back of a Mini Clubman, which eliminates a lot of trouble hauling it around.
The folding bike (and the Mongoose) is going to Burning Man this year, so I expect it to never look as good as it does right now.
I'm glad I found this site, interesting conversations so far.

@Marty How many electric bike do YOU own, and for how long? I've owned three during the last 6 years, and can tell you that a single speed pedal assist electric bike with throttle is fine.
