I have a 1 year old son and my wife wants me to send him to the nursery with an electric bike, so she can pick him up in the afternoon and bicycle back home with him in a car seat for the bike. I searched and searched and only found one with 30kg of weight. Couldn't find the manufacturer home page, but the product name is Eisan Swifti 20. From the sound of the name it sounds like Taiwanese product, and it says the bike supports up to 1 carseat. So do you have any alternative suggestions on light, foldable electric bike in the US or in other countries? Electric assist power can be very little as fully electric bike will require license and certification, and she will need only 10 miles or so of electric assist per day. Doesn't have to be foldable but I plan to put it in my 6-seater X with 3rd row folded.
