I am a new member of the forum and a retired senior citizen. I have a single speed Day 6 Bicycle which I bought this summer. I am interested in installing a motorized engine and would like to know if anyone on the forum has one of these bicycles or can give me some ideas on how to perform this feat. The Day 6 people have a conversion kit, but they want about $1500. for it and I think this is way too much and really out of my range. Thanks for any help given.
