I can't find any website for the Houston club. I'd like to see more of this.

Not much progress lately. It's a rather complex project for a mother and her severely retarded
daughter. There will be pedals for the daughter, but they will be turned with power from the mother,
to provide the girl with "passive exercise". I had to build a declutching device,
http://bikesmithdesign.com/Nikki/NikkiClutch.jpg so she doesn't have to drive the girl's pedals on
hills or if she gets tired. A shift lever will move a cable operated lever, to depress the rod on
the end of the shaft, to dissengage the sprocket from the shaft. The sprocket will be driven from a
4th chainring well inboard of the other 3.
The bike is an EZ-1, with an additional 1.5" of rake, 155mm cranks and the BB moved forward 3".
Handles MUCH better than stock, even as a 2 wheeler.

lower the CG I replaced the seat frame and struts with Aluminum EZ-1 Lite parts and replaced the
bars with these;

To complicate things, she can't climb over anything to get into the seat. I had to make cranks that
are cantelevered out from the EZ-1.
http://bikesmithdesign.com/Nikki/NikkiCranks.jpg There will be
another support bearing at the shiny area just inboard of the left arm.
The sidecar wheel sits in a swingarm like arangement that can be adjusted for height (to adjust
tilt of the EZ-1) camber and toe-in. All of the major subsystems are complete. I just need to
create the sidecar frame, build the seat and move or add about 20 braze-ons. Seat will be based on
a fiberglass race car seat that surrounds the rider. The bottom has been cut out, and I'll use a
BikeE seat base. (The BikeE seat base is a good shape, UNLESS you have the cranks well below the
seat. Like a BikeE. ;-)

MnHPVA Founder Dave "Weld first, measure later" Krafft built the "sidecar" with the help of the
owner, Tim Dunsworth. The bike is an early Tour Easy. Some pix.
