A couple months ago our member, Crazeehorse, commented in a thread about buying gas motor kits from Bluecollarbike.com. I called the business (phone number is on website). Owner answered. He seems very straightforward and fair on the phone. Easy to talk to, both he and his wife who helps him out with sales. Price is good. Esthetically pleasing, too, per his pictures. Assembly has that motorcycle look, once mounted. Kit includes everything at $185. Motor is from China, but has needle bearings. His sales are brisk, and he thinks highly of his product and service. Has anyone bought his kits? I'm tempted, but would like input from someone who's been there and done that.
