You could drill and sleeve 2 extra holes on the swing arm and build the extension off of the two new holes. that way you can keep the ladder and the bike rack and just remove the bike rack when needed!
I just dont see how new dads can stay in "bike shape" and not ride ebikes haha if i still had my normal pedal bike i think id make it up the hill once for one trip down and pack it up and go home hahaha
I hear ya. I try and sneak a ride in 2 to 3 days a week usually during my lunch. Keeps me pseudo bike fit. But I do ride my Ebike art least once a week when im tired or just don't have enough time.
