New Trike Prototypes

Our amazing trike designer/engineer/president was hard at work this weekend. He has come up with a few new trike prototypes. 

In the photo below: Up on wheels is the completed frame for the experimental  DOTT "Ultra Compact" trike, to be tested this summer. In the right, foreground are some of the parts for the slightly larger experimental "Compact" version of the DOTT trike, waiting to be built. On the bench in the background is the partially built frame for a low, fast, seven speed version of the DOTT trike to be used to test some concepts and also advertise for HWI in local events and races.

Below: A rear view of the full size DOTT trike, seen on the left, as compared to the much smaller DOTT Ultra Compact, seen on the right.

Below: A view of the full size, second generation DOTT trike in the rear and the new and improved third generation DOTT trike, in the Ultra Compact size, in the foreground. All future third generation trikes, in all sizes, will have numerous small improvements which will strengthen the frame and reduce weight by several pounds. They will also have an available option for easily removable side supports for those who need them.

Below: For several years now HWI has had a "full size" adjustable hand pedaled trike design that can fit a wide range of people. However, we have come to recognize the advantage of having at least one smaller size, adjustable design to fit larger children thru small adults. As a part of our effort to try and define what the ideal dimensions would be for this smaller, second size, we are building two new prototypes this summer. For now they are being called the "Compact" and the

"Ultra Compact"  (or "Cutie") prototypes. They will be tested with a wide range of users to see which dimensions work best for this smaller size.

The partially completed trike shown in this picture, the first Ultra Compact  prototype, will spend a few months being tested in the States. Later this summer, this particular trike may end up going to the jungles of Peru for use by a young disabled girl.

The Ultra Compact DOTT prototype shown in the foreground is approx. 5 inches shorter, 2 inches lower and 1 inch narrower than the full size version in the background.
