Super nice! How fast does it cruise? Did it take a little riding time to get inner ear balance issues sorted out with your head tilted so far back? The apparent joys of being 6'6" with a long inseam, using a 700c front wheel while having a low seat height. Good to see you're a man of action 4th 'bent in 6 months!?

Thanks guys!
Sofabike I'd say a v. My hands are a little farther apart at the top then the bottom.
Pugscat it wasn't hard to get used to, but being that flat makes it hard to use body English for stability at times.
On the flats I like to cruise at 28mph.


After adding the carbon fiber it sure climbs good! But my roads sure did get rough!

28 mph that's fast. It might be a hoot to fully fair it. Do a bubble boy and look between your feet.

Very slick! Is there a limit to having leg muscles working higher than the heart? Any fairing would need to minimize the clear canopy in favor of a white color to reflect solar heat and have plenty of internal air flow. Perhaps cold water circulating around the neck area might help too.

John builds one of the most advanced bikes in America(or anywhere), and is following a proper training plan resulting in his becoming one of the best recumbent riders in America, and all you can do is ask the same ridiculous questions and make the same ridiculous posts. Some things never change.

Thom you could end much frustration by publishing an e-book and generate some income. Anyone who spends the time and money to build and race a high performance machine like this deserves a great deal of credit.

Grant, I'm only perturbed by people who populate forums, but never do anything for the sport. I started to do a book(after seeing Bryan Ball's chapter on our adventures), but decided to put it all online for free. Training and design advice is free to sincere persons for the asking. As John B. has found out all too well! He is the real deal and quite a pleasure to work with.

Thanks, I may never be able to race but I will use what skills and knowledge I might have to help all forms of human powered transportation.

Grant, you seem to think I only work with racers. This is far from the truth. I constantly work with beginners, seniors, and the physically challenged. The same can be said for equipment choices. My present work with a 76 year old rider is just as exciting as helping a world class rider like JB. So please stop categorizing me as some who only helps the speedy. And continue doing whatever it is you do.

Looks great.

What was the weight before and after adding the carbon?
Did adding the carbon make much difference besides extra stiffness when climbing?
Did you feel confident seeing the road in front of you?

Electric the carbon fiber only added a couple of pounds. I built a cf seat and removed the aluminum one, so that helped with the weight. Total weight about 38 lbs
I notice the stiffness on flats too when I accelerate hard!
Seeing isn't to bad, I can't see directly in front of the bike but what I see comes up real fast at my speeds!
If I need to see better I just sit up, which also works as air brakes!

Actually I am equally interested in your antique replicas. Curtiss - Wright and Harley Davidson were both started by bicycle builders. My main task is to streamline commuter bikes. Body position is super critical so I am interested in both muscle mechanics and blood flow in the best aerodynamic position. I note the fairing around John's water bottle and I am trying different positions for water bottles on my own bikes. What makes this forum great is the mutual support of new ideas from unusual sources.

The beauty of John's fuel system is that it is reloadable on the fly. Essential in ultra racing. Another well thought out aspect of performance riding.

John is a fine example of how the sport is advanced. He is a real smart guy and wants to go fast. So we share and discuss ideas, then he builds it. He doesn't spend months posting made up theories on some forum. He doesn't reinvent the wheel. He doesn't spend months building a bicycle. He builds it and refines it. In short order he has what I believe is the fastest road bike in America

At some point all theories were made up ideas. Time is money, if you have it good for you. As for the original question of optimum body position I'll find someone who knows.

This is a post about JB's most excellent bike. You can't post as many undefinable questions as you want, but in the end there are people who get things done and there are those who ride keyboards. Body position with relative to the application. There is no mystery except the one you create to make yourself sound intelligent.
