On Wednesday, October 3rd, 2001, I took delivery of the first production build of a new GreenSpeed vehicle model: a convertible tandem recumbent suitcase tricycle -- GTV.

This is how I used to lock the trike before the lag bolts were put into the concrete. The gas company would have had a fit if they had seen that I had locked it to the gas meters.

This is how I lock it inside our co-op. Notice how I loop the cable through itself and then through the other wheel, then through the lag bolt and then extend it to another cable. If I am really serious about locking it, I put the cable through the forward seat bars on both seats. The room where I park it is a bicycle only parking garage that houses 110 bicycles and it has automatic lighting, automatic street-level doors and video surveilance. I am able to drive the tandem trike straight into the room.

These are general views, with a new model CarraDice SuperC without the heel cutout. The black racks extending upwards from each seat-top was originally ordered to carry a canoe, but it could be used to carry a wide variety of things including step ladders, lumber, sheets of plywood and gyproc, etc. I carried my wedgie (diamond-frame touring bike) home with it when I originally went to pick the trike up from the shop.

Here is an overhead view of the rear rack detail.

I found a handy place to stash my U-lock and two security cables.

These are general views from each side without any bags.

This is the head-on view. I have put on single-sided SPDs and added rat traps for others to use since they won't be dragging on the ground. This gives a good view of my asymmetric mirrors, front mudguards, steering linkage, headlight mount on the otherwise unused emergency front derailleur tube, timing chain on the (driver's) left and Schlumpf mountain drive II two-speed transmission on the right in the front as if it were a passenger tandem. You can also see the spedometer mount and a bell mounted beside it. I think I will actually move the bell to one of the handlebars rather than have it on the mirror tube. You can also see the disc brakes and their hoses.

This is the view from above the front seat showing many of the same things as the head-on view.

Here is a bit of chain detail, showing the timing chain on the left and the main drive chain on the right. The main drive chain is probably about 20' long, likely 4 standard chain-lengths. GreenSpeed supplied one quick-link in the timing chain for disassembly and two quick links on the drive chain to be able to convert it easily between tandem and solo.

These are general views of it flipped over resting on the overhead racks.

Here are the rear main tube S&S coupling and the Rohloff dual push-pull cable quick-disconnects. These match up with the front dual push-pull cable quick-disconnects to accomodate solo mode. Note also the extra set of unused emergency rear derailleur cable guides. The serial number plate may look easy to remove, but there is also a hidden location where it is stamped more permanently.

This blurry view from below the front boom shows many of the same things as the head-on view.

This is where we see how and where the frame breaks for conversion to a solo and for packing into a suitcase. To convert to a solo, the S&S coupling under each seat disconnects, the forward seat bolt from each seat disconnects, the two sets of dual-push-pull Rohloff shifter cables disconnect, the timing chain is removed and the drive chain is shortened. The front seat, rear crank, and both frame members between the S&S couplings under each seat are completely removed and the frame is reconnected using the front cranks, front wheels and steering, front frame, back seat, back wheel and back frame to run solo. The conversion should only take about 10-15 mins once I sort out a good way to store chains.
