I like the concept. I think more people will buy them once the prices come down. The $3,500 price-point is steep for most. Also, for those in the city, you would want a secure place to stow them when you get to where you are going.
Motiv has electric bikes starting around $1750 and an extended range model for about $2150. Beach cruiser style with 6-gears. I’ve been wanting to get one for a while. Might have to talk Two Kids’ Mom into getting his & hers models.
