A cursory inspection of the few, distant images of the Mint T9 on the web reveals clear visual clues suggesting that it is not built on a FnHon Gust 16" frameset.

Many manufacturers have tried to emulate the Gust 16" look to cash in and ride on the success and popularity of that bike, and entice buyers who want their bike to look like a Gust 16", but can't afford or are unwilling/unable to build one themselves. Our fellow forum member's Mint is apparently one such example. The Or!gam! L0tus and the Element Troy are others.

Happy to provide details so long as clear, detailed, high resolution images of the bike in question are provided. No pix, no play.
