The only thing I can think of was that their offering didn't offer anything significantly better in terms of price or quality in comparison to Wright or ADL.Good to hear, I quite like the Metrodecker. It looks good (although I think the E400 MMC is the best looking current DD at the moment), and I think the ride is comfortable (from my experience of just one half-hour ride).
I do wonder why there have been no orders for a Metrodecker since the demonstrators were launched 3 years ago in 2015!
