The original test model. Take a hack saw to two mountain bike frames add a 2" square main tube. This frankenstein version has two long tours and many test miles under its neck bolts. It can be broken down and was actually boxed and flown as luggage. It now resides in the bike barn at the test track. Often giving guests their first back to back experience.
#2's main frame was created out of galvanized steel tubing normally used for supporting street signs. The telescoping tubes and clovis pin system allowed for break down and adjustment. It was also an experiment with a Zox style front wheel drive. It was my first foray into welding and it was about as heavy as a couple of sign posts, so after some short rides I broke it down and use many of the parts for #3.
I fortuitously met Scott Dion, a frame builder with his own shop. Scott had never built a tandem or a recumbent before, but he was adventurous. We worked together to created #3. Here is a video of Dot & I on a very early test ride.
Back to the duel 26" wheels of #1 and utilizing two of Cruzbike's conversion kits (Note: the kits are no longer available, but take a look at Cruzbike anyway, they're cool). We put some test miles and a short tour on it. I like the larger wheels and the easy adjustability of the Cruzbike, but I still haven't gotten comfortable with the direct front wheel drive, so #4 went back to Zox.
The current model built by Fraser Cycles, Scott Dion's company, is pictured to the left fully packed including tent and sleeping pads for last summer's tour of Cape Cod. #4 has become our main ride and has completed four major tours. Having eyes behind you is helpful when dealing with traffic and when keeping track of other bicyclists on group rides, plus the person in back has an unobstructed view. Here is a video of the current model in action.
