Homemade recumbent

Hi, I am new to this forum. I was searching more info for my (our) tandem but I saw this section on recumbent. Here is a picture of the recumbent I build last year. It took me about 5 months by spare time to make it. I have more pictures about the construction. Feel free to askequestion about it.

Have a nice day,
Michel

Nice! Great idea to run the chain through those tubes; is that some type of rubbing hosing or pipe? I've never seen this done before.

Full suspension, panniers, fenders... I want one.

What's the seat made of? Is the design painted on, or did it come like that?

It would be great to hear some more about how you built this... must be some interesting stories after 5 months of work. :-)

Hi,
The tube for the chain is a kind of polyethylene tubing. It is quite rigid and has a low friction coefficient. Once the chain is oiled there is not much friction in that tube. It was bought from Mcmaster. The tube has the advantage of keeping the chain clean for a longer time and my leg too. I was guide a lot by european design. ie: Hpvelotechnick, Optima and Challenge.

The seat was bought from an Optima dealer. It is fiberglass. I have installed a 2 inches filter foam over it that help for aeration of my back. The seat is cover with a jacket made of lycra (Swiming suit).

The recumbent is built around a 2" muffler pipe. A bit heavy but easily bendable and cheap. The frame is strong. It is all tig welded. The main problem came from the rear swingarm. I wanted something very rigid and not too heavy. It was a bit hard to figured out a proper location for the brakes and a proper chain line. The design of the swing arm took over a month by itself.

The pannier was also a lot of work. I had to build a tool to properly bend the aluminium rod. The one you see on the picture is the second model. The first one was not strong enough.

Once finnish the bike was sandblasted and it was painted with a powdercoat.

I have many more pictures but no place to put it.

Bye,
Michel

Very nice, It's easy to see the euro influance in your bike. Very few of the homebuilts ever reach that level of polish.

Thank you for your comments. At first it was suppose to be much simpler than this. The idea was to make a basic recumbent and try if I would like it or not. But it went further and further and further... and end up like this. The original model had no suspension. But after renting a non suspended recumbent and riding it around here, it was out of question to build something without spring. Our road are very bad. Contrary to a wedge bike, on a recumbent you cannot support your weight with your legs when roads get rough.

After all this, I am still not sure if I ever will be a pure recumbent cyclist. I enjoy riding it but getting rid of my regular bike huuuuummm I won't say yes...for now.

Bye,
Michel

Michel, I have room on a couple different servers and I would be happy to host a small page. In fact, if you sent me the details on how you made it I would be happy to help put up a page with directions as well as the pictures!
