@harpaa01 @inthehands we have a plain Yuba Kombi to which we slapped an electric kit. The 0 to moving is snappy[1], the biggest challenge it to get used to the kids changing your balance in those critical moments.
[1] maybe too much. From my non motorized bike experience, I keep a foot on the raised pedal when stopped, and the system feels the weight as force and tries to start moving. Maybe I should talk to the BRM who installed it.
