My new recumbent trike

I've been wanting one of these for years, and finally decided to just build one. I'm considering it an early Christmas present to myself.

In order to get all the parts and pieces, I hacked up 8 to 10 other bikes that I salvaged from the local dump.

Basically, it's called a recumbent tricycle. The two wheels in front steer, and the rear wheel is driven by a really long chain that I made from 3.5 other chains. It was a bear to get the angles for the steering arms correct, and the chain mechanism (not pictured) gave me some grief as well.

All in all, it was a pretty easy build, even though it's the second thing I've ever fabricated, ever. I can't wait to have a nice shop...

Here are some pics:

The bike itself:


Front: The seat was a really quick hack. It's just some OSB with carpet padding glued on, and then covered in vinyl. The bump is extra padding for lumbar support. I plan to upgrade in the summer. The front wheels are from a couple of BMX bikes.


Back: The rear section is from a mountain bike.


Finally, me on it in the bright, bright sun lookin' like a goober!


It rides like a dream and shifts gears smoothly. I'm pleased.

Thoughts? Comments?

Cool.

Do a wheelie.

The new seat will be covered in maille come summer time.

I have a few bugs to work out of it here and there still...

Fantastic. Love it. Needs two retractable scimitars out the sides and some over-the shoulder grenade launchers.

Could use a cargo shelf actually, maybe work that into the back of the seat.

Big spring shocks might be helpful too, you can't squat 8-10" like you can on a normal bike when you anticipate a bump, to cushion the impact. Even running over a little 1" board is gonna feel like you just got paddled.

Needs a shelf in front so you can mount a little netbook or LCD screen to watch movies.

Definitely needs a stereo system.

Needs a battery and a motor, for boost, could fit behind the seat.

Could use some armrests.

A winch, also hooked up to the pedals, would be awesome, with an over-the-shoulder crossbow to launch a barbed spear or grappling hook. You could pedal yourself up a tree, or the side of a building.

Weapons: Nah. Though maybe some water grenade launchers...

Cargo shelf behind the seat: Working on it.

Spring shocks: Unnecessary! I just rode it a couple miles and bumps are absorbed quite nicely. It doesn't like high speeds either, so I just crawl over bumps anyway. My next bike, however will have a mad suspension.

Shelf in front: Maybe. I might make it retractable.

Stereo system: Not a bad idea...

Battery and motor for boost: Meh. I need the workout.

Armrests: Maybe. My arms don't get tired tho...

Winch: lol

Other stuff: I plan to either make a permanent magnet alternator or just use a stepper motor to power lights and whatever else. I may get some solar panels too. I'll also eventually need to replace the front wheels with ones that have beefier hubs. These 3/8" things in place now just won't cut it for long.

Not bad. Its technically called a tadpole trike, but you made it, call it what you want.

In my spare time I work as the head engineer at a recumbent bike shop in Western New York. I might add it is one of the largest recumbent bike shops/retailers in the north east. Who would have thought in the middle of Alfred. Here is the Bicycle Man's website.

I have had a hand in designing many parts for the Linear brand of bikes shown here:

Linear Recumbent Bikes

We make them in house. Its fun to see hard work make people happy.

We don't do a trike yet, and I would imagine they will not be put on the line-up for some years, so its great to see a home brewed version.

We're moving to a huge new location right down the road, so things are a bit scattered, but if you need any design advise Peter is the one to get a hold of.

If you want to buy a new seat instead of making a new one, Peter has the most comfortable recumbent seats made, or have been made. They are Burley seats, and the only way to get a new one is from the Bicycle Man. Burley closed up shop and we bought out their stock. Just an idea.

Again, looks great.

Haha yeah death ray or flame thrower.

Other than that my comments (as usual) have more to do with the body on the wheels than the wheels!

Sweet ride! Even sweeter that you made it yourself!

I love the tadpole design, both aesthetically and as a engineer...

I've come to anticipate this. Thanks for the compliment!

Me too. It was a blast to build. Some of the angles aren't perfect 'cause I only used a tape measure maybe twice throughout the entire build, but it works and I'm proud of it.

Did you weld it, or did you find the right parts that it could just be bolted?

A vast majority of the connections are welds that I had to do myself. There aren't many factory welds left, and only two spots are bolted: A bracket behind the seat that used to hold a spring, and the connecting arm between the two front wheels.

I can take a few more pictures if you want.

Did you do it by eye, or did you have a design? I've been thinking about building one for ages, but I'm not sure how to work all the linkages for steering and pedals...
