I'm making the Above Seat Steering (ASS or OSS) mechanism. This thing has 2 headsets ... one above the front fork ... the other in front of the seat. They currently are linked by a rod (which I borrowed off my lowracer). When the rear one is turned ... the front one turns simultaneously in the same direction. Monday I'll work on the short riser that connects with the handlebars. I'm also working on a different bottom bracket unit. You have to cut up multiple bicycles to get the parts you need to make one of these ...
My grandson just had to have this fiberglas seat that I got from S&B Recumbents ... the bottom mount was sawed out of a Direct TV mounting bracket ... I kept a bit of the bend in the rear for rigidity. Welded to the frame ... there is no flex in it ... and it's wide enough to give good support to the seat bottom.
About halfway up the seat back ... look inside the purple rim ... and you'll see the bracket that came with the seat. I just welded it to the frame. The seat is a compromise angle that will meet the needs of the grandkids. Next to work on the steering.
I've attached the ring to the spokes and cable-tied the spoke crossings. The cable ties make the wheel more rigid. I need to put a solid axle in there to replace the QR (quick release). Something about the QR being prone to release under the load while you are whizzing down the road. Now, am I going to keep the Disk brake or replace it with a V-brake ???
I got in this nice 2-stroke, single-cyclinder motor from Bob at BlueCollarBikes. The first problem I noticed was that the diameter of the front tube was too large ... so the bolts wouldn't slip around it and there would be problems bolting the engine to the front tube.
The seat tube was okay to bolt the rear of the engine to ... but it doesn't look like I will be able to attach the carburetor to the engine (see that little tube touching the top bar? That's where the carb attaches.) ... just not enough room inside the frame.
There is this old Peugeot sitting around ... and the frame tubes are the right diameters ... and the engine will fit inside the frame (complete with carburetor) ... but for some reason the pedals don't have enough spread between them (which means they will hit the case ...) and not go all the way around. I've got emails out (to motor bike aficionados) looking for solutions to these problems. Maybe I'll have to go to the flea-market and buy an old single-speed bike ...
At WalMart yesterday (big box store) ... I found this bicycle on sale. It's a Mongoose Paver ... aluminum frame, 3-piece crank, 7-speed rear, 700cc wheels ... It is so much cheaper to buy these complete bicycles than to buy separate parts to build one. So, the questions is, am I going to tear this one into pieces for other projects ... or keep it in one piece and add a motor to it???
This reminds me of those big black bicycles they have in Denmark.
It seems I can never have enough Recumbents ... made 2 Bentech LWB's, 2 Bentech SWB, 1 Toureasy clone, a LWB lowracer, 1 Mach2, 1 Mach3, 1 BMX SWB, bought a Sun EZ-Speedster, made a DeltaWolf trike, a LongJohn cargo bike, a cargo trike, and a AZ Warrior trike. I LIKE USS! See some of my bikes below ...
Due to the intermediate jackshaft, this flies as fast as a 26" rear wheel. (co-designed with S&B Recumbents - no longer in business)
Bought the Bentech plans, made the jigs, and made this from a Huffy Mtn bike & a muffler pipe. I extended the maintube 2" behind the front wheel. It handled nicely and became the bike I rode most because of ease of transport and visibility in traffic. (Bentech no longer in business)
My Wife loved her LWB Bentech ... as you can see by the smile on her face!
TourEasy Clone (found plans on internet). Early on, Gardner Martin did sell plans. Later, he went to selling completed bikes only. Used this bike for about 14 years. Recently I've been pulling parts off of it to use in other projects.
SWB Fully Suspended Mongoose BMX - this was the first "Fully Suspended" type recumbent that I built .. by adding the front boom onto the BMX bike and changing the seat. Needed a stiffer spring suspension in the rear ... everytime it flexed, the bike changed gear due to the change in chain length. That was kind of disconcerting ...
Sun EZ Speedster CX
This is a much maligned SWB recumbent. I love it! And have had many enjoyable years riding this easy steering bike.
Venice Beach Trike
Jack Baker (S&B Recumbents) made this for my wife, a couple years before he died. She needed something more stabile than a 2-wheeler. Despite the high CG, she has yet to fall over on it.
Another Bentech design SWB
I was building this for a guy, and actually rode it. But he changed his mind, and it is still in the shop.
AZ Delta Trike
I was going to build this racing trike for myself ... but the wife gave it to a grandson. So I put 20" wheels on it instead of 26". The grandsons fight over this racing delta trike. I really like the square tube building concept. Easier to align things.
Modified Delta Trike
Totally changed the rear configuration so the rider sits higher ... and mounted a rear luggage rack that I made
Long-John Cargo Bike
Built from plans on Toms Cargo Bikes website ... still need to hook up the steering and go ride it. ...
Dutch Cargo trike
Great way to go grocery shopping!
built based on A.D. Carson plans
AZ Warrior trike
Love riding this now! (Plans from Atomic Zombie). 26" rear wheel, 11-34 MEGARANGE 8-speed cassette on the rear, 22-32-44 cranks on the front.
