Harri Mommos' Homebuilt Recumbent - 6/2005 - See
Harri Mommo has written from Finland to share his new
homebuilt short-wheelbase recumbent.
As you can see from the photo below right, he built this bike
from rectangular steel tube.
Harri has put together a nice web site showing the steps he took
constructing this bike.

"I wanted it to be a low ride framed but not front wheel driven.
It took me couple of weeks to finish the drawings and two months to build.
I've got the whole process documented and a couple of dozen pictures taken along the way.
I am planning to set up a small site to share the information.
"As for riding the bike, I really don't have anything to compare it to but it feels stable and most of all fun to ride. It goes straight without effort (not yielding to left or right).
The frame turned out to be just the right size according to my plans which I based on my own body
measurements. Attached is a picture taken during measuring. I made drawings in 1:10 and 1:1 scale.
One thing I've found negative is the lack of carriage possibilities. I've
tried wearing standard back bag on my chest but it doesn't feel comfortable.

This last spring Harri ordered some
nice pulleys from a company called McMaster-Carr in the US; they
are shown (the larger idlers) in the photo at right used as
chain guides. Nice application for a quality product.
...to tell you about how good the McMaster-Carr idlers worked for my bike. Compared to the earlier chain discs they run almost silent. Also the chain tends to lean on either side of the idler so it wears one side at a time. When worn out one just has to flip it over for the latter half of mileage.
The guy I built a bike like mine for was so enthusiastic about it he asked my permission to call the major newspaper in northern
Finland about the bikes I was building. A week ago I had a friendly visit by a cute reporter. Attached is a scan of the newspaper for a little
Harri sent along a copy of an article
which had a large photo his friend
and him riding these cool bikes. Of course the text was all in
Finnish and unfortunately I don't (yet) read the language. It is
hard to believe that any language which uses the same characters
as American English could be so totally unreadable by this
somewhat literate American. We live among Finnish folks here in
Michigan's Upper Peninsula so it does make sense to have Finnish
be my second language. Someday yet, eh?
