Not now Terry. Hope he gets back on the design of the four wheeler he has been riding.

Notice all the lil pieces that use to be aluminum are now carbon. Even the hinge on real wheel well.

A dip instead of a chain canal. Chain canals are pain to build and take unnecessary time. He still has same heel wells.

Something i like is lateral rear chain wheel housing.

Boom is different.

Do have this photo:

Hmm, dip? No chain canal, Is the idler recessed into the floor?
Interesting for sure!
Is the floor flat or just a dip down?
Those lateral supports will stiffen the floor a lot!

Well, technically, I agree. Most of the bicycle costs are the components, not the frame (which I agree these do not have), so the analogy holds fine, in my mind.

The term "monocoque" is a more accurate description of this type of structural shell used for most lightweight, performance velomobiles as well as race-cars and aircraft fuselages.

Hey chapooski, where you been and hows it going. What dont you post pics of your velomobiel. PLEASE!

32 years of flying, monocoque @ airport means many many many parts rivited together make one part but each relying on each other for strength. A french word. Wright brothers was basically a welded frame with rag wings. A piper or cessna is mono aluminum. A cirrus or Lancair is one carbon fuselage. Unibody word probably was started with dr. Macpherson who invented Macpherson strut while working at Chevrolet in mid 50痴. Unibodies hold suspensions without a frame. Some have small sub-frames to hold engine.

A modern unibody is all one part. Its a lil mono if u consider the cf bridge and rear wheel well glued in.

Your velo like mine is true-mono unibody with Macpherson struts. Unlike a challenger velomobile that sets atop an ICE trike. Not a unibody, i call it a shell on a store bought trike.


3 kinds so they say: as said below 殿 term frequently mis-used.
1) monocoque. (Didn稚 even exists back then unless it was a baloon)
2) semi-mono.
3) true- mono



Here痴 another shell on a trike kit from florida:
