I have a Sekai that I got for free a few months ago. I pumped up the tires and straightened the handle bars and away I went. Seems to be all original and all was great until the back tire blew out the side because they are original tires. Any idea on what year or model this is? I can get more specs if needed. any help would be greatly appreciated. I'm thinking of selling it as is because I don't have time or know-how to save this bike and would like it listed correctly.
