I test rode the M Type today, the only model they had available for testing at NYCE Wheels in NYC.
To me it felt like I was riding a toy, perhaps my set up (it also felt that way) was totally wrong. The shifting lever felt very cheap, flimsy and plastic like. Braking was right on. Handling ok, I tried to do a tight
turn and my pedal hit the road big time. The rolling mechanism has a very annoying extension where my inside shoe kept on hitting. Perhaps the S type is much better, not sure, but I wouldn't use this model for longer ride than 1 or 3 miles, tops. The small folding is the best though.
