@Sierratim: Thanks for the direction on the through axle replacements for the Burley hitch. We have Burley hitches on the Trek SC +7 and the Electra TC 8i but would like to pull my grandkids behind the Vado’s as well. Pulling the trailers up hills with ebikes is a breeze, much more stable too. FYI, I also liked the crimson color, it is more of a dark brick or cherry wood color vs. a bright red. Also wanted something different than the flat black on the SC. Appreciate the help. Maybe I’ll see you sometime out on the trail.
