If you want to ride an Electra Townie, this feels the same. The Trek "Pure" is the Trek's version of the Electra Townie, before Trek acquired the Electra brand. The bike has a laid-back, cruiser feel to it. The saddle is on the wide side. These bikes are comfortable, simple, and fun.
This small size bike should suit riders in the range of 5'2" to 5'6", and maybe another inch on either end of that range.
For your safety, all bike rentals come with one adult bike helmet.
