Hello, it appears some people are interested in my project which is good to hear so I have made this thread to get as much help as I can. I have 10 weeks until I will be busy, this means I have 10 weeks to build a fully operational streamlined bicycle.

What in 10 weeks?

1) A recumbent bicycle steel prototype, front wheel drive. Many components to make.
2) Landing gear, launching and low speed maneuver. Landing Gear
3) Discover clearances, foot box, knee, seat, shoulders and head.
4) Aerodynamic shell design shell utilizing current understanding of laminar flow, ground effect and composite sandwich construction.
5) Foam plug.
4) Female mold.
5) Vacuum bagged carbon fiber foam core shell.
6) Windscreen.
7) Integration of components.
8) Test ride.

Purpose

1) Build something that looks awesome.
2) Exciting exercise and commuting around town in traffic.
3) Learn new skills in composite construction.
4) Actualize interest in aerodynamics and efficiency.

Feature Goals

1) U-turn in a two lane road.
2) Stable low speed maneuvering using landing gear.
3) Safe vision through windscreen, mirrors.
4) Easy access for servicing, flat tires, access to drive chain.
5) Adequate ventilation.
6) Shell strong enough to survive crashing.

Future ideas

Lights and indicators, tail fin mounted safety lighting high enough for cars to see.
Ventilation fan (thrust).
Electric assist.
Second iteration composite chassis.
Suspension front and rear.
Mid drive step up gear.

Inspiration


It's late I will update this tomorrow.

Oh sweet, sweet sweat box!! Hahaha. If it had a fan in front of it, it'd be easier to keep yourself cool 😎 It's not an airplane, but I'm curious how you come out. Best of luck

Ten or fifteen years ago I recall a competition for best gas mileage for motorcycles and similar shells were used. I cannot remember exactly but several hundred miles per gallon range was achieved with very small motors.

That is a big plate you have made for yourself, very lofty goals.

Good luck

You might be thinking of the Craig Vetter Fuel Economy Challenge, so interesting it was an inspiration for some motorcycle modifications of mine to improve my fuel economy.

Thanks.

When your ready for the electric assist, let me know.
👍

Yes I am, I've been on there maybe six or seven years reading while intermittently obsessed with making an efficient vehicle. This is my latest and boldest attempt.

I've been busily welding, grinding moving parts around to get everything to fit. I should have taken some pictures hopefully I'll have something interesting to show.

I have a bunch of things to do.

Project delayed. The front wheel drive arrangement I have used does not work I will have to go back to square one and consider a different approach. This project will be delayed to summer heat also.
