Building kids' chopper bikes - England

This is first ever attempt (more of a mess around than anything) by putting adult bike forks on kid's bike.

Building bikes isn't just for the young at heart. It's a past time that youngsters can participate in and learn some skills along the way.

 I built the one with my middle daughter using Land rover steering arms on forks.

Bike builder and forum member, Naughtyboy, of England shares more photos of his homemade bicycle choppers. Chopping up and re-building custom built bicycles a passion that he shares with his kids.

For this one, I used scrap air pipe from work (to build the) forks.

Gravity Bike Racer - England, UK

Custom made Gravity Bike.

John "Doc" Warner shares some photos of his modified bicycle for Gravity Bike competitions. Named "Hee-Bee GB II", Doc built the gravity bike for a competition this past May.

What is a gravity bike?

A modified bicycle with a frame that's low to the ground to reduce wind resistance and the center of gravity. It has narrow handlebars, no pedals or chains, front and back disc brakes, knee rests and long foot pegs so the rider stretches out horizontally.

Lightweight and built for speed.
The goal is to descend steep downhill courses to reach insane speeds, often exceeding 90mph. This extreme sport has been gaining popularity worldwide for more than three decades and Gravity Bike races are held around the world.

Competitors wear helmets (some races require full-face), leathers, speed suits, gloves, footwear, and elbow and knee pads. According to Doc, "It's a great sport, very cheap (to build and compete), fantastic fun, and very accessible to all abilities and ages. Perfect for DIY/home-builders. You can build a competitive bike for around £60/$100 (but) you can, of course, spend less, or much more.

"This is my first Gravity Bike build. I made it earlier this year to enter the 2014 Penn House Gravity GP and finished second overall (Streamlined Buggy beat me by just over a second)."

Making a pair of homemade tadpole trike mudguards using sink waste pipe

A bike builder shares her innovative solution

Riding a bike in the rain and sleet isn't fun when you're constantly showered with spray from the tires. Emma Wheatland discovered that finding mudguards for her homebuilt recumbent trike wasn't possible. So, in true build-it-yourself spirit, Wheatland figured out how to design and fabricate guards for her trike out of plastic pipes commonly used in plumbing. She shares details of the project and some of the challenges she faced along the way. The results are stunning. Read more>>

Chopper mania - USA

Fantastic detail on this one-of-a-kind chopper.

New Yorker and AtomicZombie member, Kempracing, has an addiction. But, don't worry, it's a good one.

He loves to design and build choppers. It doesn't matter if they're on two wheels or three. Each one is unique. Kempracing puts a lot of thought and care into his bikes. 

Nice tribute to our own OverKill!

Check out the detailed web design of the purple chopper above. He built and donated that chopper for a raffle at the Howe Caverns Bicycle Show and Swap Meet in New York this past July. A lucky winner pedaled off with that beauty.
A trike for the Mrs.

An embedded star burst heart on the trike he built for his wife, Patty. Awww.

Couldn't wait for paint. Gotta take it for a test ride.

Trying out something different with rear phat tire.

Interesting tires and matching spokes.

Tay's homemade chopper trike - England

Tay helped his dad build this chopper trike from scrap bike parts.

Submitted by AtomicZombie forum member and bike builder, Naughtyboy.

"We built this because my youngest two kids needed bigger bikes and they both love workshop time with daddy.

One of the kids from school turned up on a shop built chopper, so Tay looked it over and said, "Me and my dad can build (one) better."

We've built all sorts from scrap wood and metal and they have even helped me with rebuilding an old Land rover.

Tay decided he wanted a trike after seeing my Gladiator (chopper trike) plans, and he also looked through my 15 other plans to plan future bikes. The front is based on the Gladiator chopper trike and the rear, I think, was based on the DeltaRunner Recumbent Trike, but flipped over.

The forks are made from 16mm od x 8mm id blow pin shafts left over from machine re-furb at work. Suspension is made of old trampoline springs I found. The handlebars are from an old rotavator which I'm planning on using engine on quad-cycle (so many ideas, so little time).

I had to turn some sleeves to fit them as id was bigger than od of forks. Tay helped with drilling on lathe. Front wheel is 20" and back started as the same size, but are now 26" as we needed the smaller one for his little sister's trike.

I just wish he would let me finish painting it, but he's too busy racing on the road with his mates! I am impressed with how tight a turning circle it as and how fast he can go."
