I have two of these kits complete with instructions and extra drive wheels I had them both installed on folding bikes and they work great with low use. Moved to NM and got busy with a new job and they sat in the garage. I sold the bikes and now need to sell these two motor kits. These sell for like $600 to $800 new. I'm going to make this a no brainier for a quick sale ......$200 each plus actual shipping cost both kits are in good working order ....one engine has a plastic shroud that has slight damage that does not affect performance see photo.
