original question:
when I started 10 miles seemed a lot, last year (beginning)
I have since ridden up to 83 miles in a day. Hoping to hit a century soon, if time and opportunity permit. It depends on the terrain but a 50 mile ride is a decent weekend ride for us now.

and, yeah, I got an E too. Seats are out for the summer, with a nice durable mat in. It has been hauling my bikes, kayak, and camping gear, among other things. Without the seats there is a ton of room in the back.

I love it and wish I'd gotten it sooner!
