Does anyone know if I can attach a child seat in the back of the Rush/Cty? I tested the Rush/Cty today and absolutely loved the ride. However, I'd like to attach a child seat to the rack in the back. The rack on the Rush sits atop the fender and I am not sure if it can carry the weight of a child (approx. 25-35lbs). I am worried the weight of the child may make the fender touch the rear tire. Has anyone successfully installed a child seat? I'd really like to get the bike if I can make this work. I'm open to other suggestions.
