The model H hybrid transportable wheelchair is almost the perfect solution for travel. It folds and unfolds easily, it's lighter than any other competitor, the battery is easily removed, it rides smoothly and provides a comfortable seating position. In manual mode, there's no motor drag. What would I change? The controller isn't removable, which leaves it vulnerable to breakage from the rough handling experienced on airline travel. Providing a quick controller cable disconnect would make the Model H the perfect travel companion.
