from the pics, it looks to have more than 36 spokes which can cause a sprocket mounting problem
I'm currently building a schwinn majestic, but that isn't very good for a really tall person & kinda requires a slant-head motor or stubby spark plug.
I used to build most any schwinn cruisers that had 7 speeds & 36 spoke wheels, and all worked out well except that I couldn't get my feet flat on the ground : )
