Hello, here is my second Project. Holger Wagner, Germany.”

Toby’s Cyclops Bike Chopper

“Hi. I’ve attached photos of my bike.  I built it several years ago as part of my A level tech project, but have only just got round to sending it to your guys! There’s plenty more of the build process at https://picasaweb.google.com/117393189104529565918/Bike

The bike comes in at almost 3 meters long, has a liquid-filled top-tube and a Schwinn stingray rear wheel, fitted with 3-speed hub gear, controlled by a suicide shift (there’s also a suicide bell, just because).

And just to top it off, the electrics run off rechargeable batteries inside the fender, with front and rear (glowing exhaust style) lights each controlled by a switch behind the saddle.

Hope you like it, Toby”

Vigilante Inferno by Tim – UK

“Hi folks!

Here is a picture of me riding the Vigilante I completed last year for the Lord Mayor of London’s Skyride, that I took part in this weekend. It was like having a bad itch, trying to keep it under wraps for so long, but what a blast riding it through the streets of London!

The pic is me riding along Embankment along the side of the river Thames, after passing Buckingham palace and riding down The Mall! I felt like the king of the road! On this bike I think I was! The plans and instruction were great, and it was a blast to build and ride. I only had 4 spokes on the back, and decided the same on the front would be cool to!

I also added 5 speeds on the back and some small changes to the bars, and added a pivoting sissy bar friction brake that smells of burnt rubber when you use it, and at higher speeds actually smokes! How cool is that? To say I am happy with the bike, and had the best time ever would be an understatement! A grin from ear to ear that has been permanently fixed since the ride!  All the very best, Tim Heyes”

KoolKat SWB recumbent by Tim

“Hi Brad/Kat. Thanks again for the inspiration.

Having bought a few plans, in the process of completing my quad with 2 wheel rachet drive, I got a copy of the Bike Bonanza Book.

So after 2 days effort my son now has a KoolKat recumbent.

Such an easy build should be recommend as the starting pint for everyone, as it is very pleasing to get such a good result so quickly.

Thanks again. Please post the photos if they are suitable. Kind regards, Tim aka go1000go.”

 

New Zombie from SW Missouri (Springfield)

“Hi, guys and gals. My name is Amos and I’m a Zom… newbie with about 30 sec. of stick welding experience (which was 5 or more years ago) who’s chomping at the proverbial bit to make himself a custom bike. (BTW, are all members of the forum considered Zombies, or just those who’ve completed a bike?)”

Ground-clamp idea, good or bad?

“I have a Hobart Handler 140 MIG with gas. I find that the Cheapo “jumper-cables” type grounding clamp it comes with often will not stay on med-large diameter tubes, so, I was thinking of get a pair of c-clamp style vice-grips(like in the pic) and drill a small hole(where the red dot is) and anchoring my ground wire to them…”

NEW: Spirit Short Wheel Base Recumbent DIY Plan

Recumbent bicycles offer an aerodynamic advantage over upright cycles due to the reduced frontal area hitting the wind. You also have a massive strength advantage as you can now deliver the full power of your legs directly into the cranks as your back is pushed into the seat. On an upright cycle, you can only deliver as much force as you weigh, and any more will just lift you off the seat. Having the cranks so high from the ground also means that you can blast into corners without slowing down or worrying about where your pedals are.

The building process is designed to allow anyone with a Do-It-Yourself desire to finish his or her own version of the Spirit SWB without requiring previous bike building experience or specialized tools and skills. The plan is laid out in a format that makes customization or alternate parts usage a breeze, so you will certainly be able to include your own imagination in the process of building a fast recumbent cycle.

With the adjustable bottom bracket and unique frame design, riders with shorter legs will be able to pilot the Spirit SWB without dealing with crank interference with the front wheel. All components used can be found at your local bicycle shop or salvaged from another bicycle, and there are no machined parts necessary. There is plenty of room for your own design changes, and the Spirit can be built using the parts you have available to you.
