While looking in a giant camera store in Japan I saw some ebikes. They were pretty interesting, many were kind of the minivan of the bike world like this Panasonic I took a picture of. The front thing is for putting a kid in and you can get another child seat for the back too. No idea what specs are other than they say it can go 63 Km. I doubt they are worried too much about speed since everyone goes pretty slowly on the sidewalks without helmets there. The price is 143,310 JPY which converts to about 1,150 USD (this was the most expensive bike they had). I really like how utilitarian the bikes were there. Seemed like 1 in 10 bikes had an electric motor there, which meant I saw a lot of ebikes since there's bikes everywhere.
