This was a project my son and I started when he was five. We spent almost every Saturday and many evenings working together, and it still took almost 12 months to complete.

The buggy was built to specifications provided by Edge Products, based on an older model Trax II build.
Our goal was to build something a child or adult could ride safely, but was tough, powerful and fast enough to be heaps of fun.

We wanted to fabricate as many parts as possible ourselves, but be able purchase those that proved beyond us.The plans from Edge Products are comprehensive and provided details on the fabrication and assembly of every part required to build the machine, with the exception the engine, clutch, steering wheel, disk brakes and calliper, seat and wheel rims; this still leaves a long list of parts to be made.

The Trax relies solely on its ATV's to smooth out the bumps, and let me tell you, smooth ain't the word for it. That said, doing 60kph, you could slam on the anchors, spin the steering wheel and turn her about-face without going on two wheels; very stable and heaps of fun in the mud puddles.

Anyone wanting to build a go cart or off-road buggy might find some pointers from this article: Build a Go-Kart or Off-road Buggy

Tools and Equipment Required
  • Welder
  • Cut off Saw
  • Drill Press (various sized twist drills and hole saws)
  • One Metre rule
  • Protractor bevel
  • Tape measure
  • Spanners
  • Pliers
  • Screwdrivers
  • Hand drill
  • Angle grinder
  • Hand files
  • Bench with Bench vice (not essential but very handy)
  • Lathe
I didn't have a lathe, so parts like bushes, rear wheel hubs, drive hubs and keyways I either bought or got a local machine shop to fabricate.

Enjoy the photos and if you have any questions, I'm happy to answer as best I can.
Very Awesome! I can't wait to see yours design!

What are the measurements
Phil Reilly5 months ago

Looking good mate!! How much did the project cost you in the end? How did you bend the frame? Did you send the drawings off to get the parts made or did you bend them yourself?

parrster (author)  Phil Reilly5 months ago
Hey Phil, To tell the truth, I can no longer remember what the total cost was, I think it was getting up to $2K. I purchase a 12 tonne hydraulic bender from eBay. Just a cheapie made in China, but did the job. I bent everything myself by drawing out the frame work full scale on my garage floor with chalk, then slowly bending and checking against the drawing, bending, checking until it was perfect. The only parts I was able to make myself were those requiring a lathe.
Are you thinking of building one?

Looks really good! Yeah I am toying with the idea although not overally sure where I would be able to drive it! I defo think theres more open road / off road in australia!!

I might end up making a petrol rc car but would much rather be able to make a buggy like yours!

I love to see how you setup clutch system..
you copied the honda odyssey fl250 roll cage
parrster (author)  michaelromeo2 years ago
They do look similar. The company who provided the plans I followed may have got the idea from the Odyssey. Well spotted. Do you ride buggies at all?
i was wondering, would a subaru robyn enginebe good enough for something that size?:
4hp
98cc
2000 or 4000 rpm
single cylindar
etc
i'm thinking of making one like that but with suspension
parrster (author)  The nerdling2 years ago
Hey Nerdling. several things to consider when choosing an engine, I found this to be an informative article on the subject; http://www.edgebuggyforums.com/viewtopic.php?f=36&t=4534

You might find your motor a bit on the light side. It would move things, but with a struggle. The Trax II buggy I built weighs in at about 100kg without the motor, add a rider and whatever motor you choose has to get them both through the mud and up hills (unless you only wanted it for flat surface, dry riding). Hope that helps. Best of luck with whatever you end up building.
where did you get your engine hand how powerful is it?
parrster (author)  The nerdling2 years ago
I bought mine online. It's a cheap Chinese motor, but if you look after them they keep going well. here's a link to eBay Australia (not sure where you're from.

Oh, that's cool, but this really needs to be a step-by-step!
parrster (author)  Kiteman2 years ago
Hi Kiteman, thx for commenting. Yeah, I would like to have made this a step by step but was unable as I didn't take step-by-step photos. It would also have been about 50 pages in length and I would likely be breaching Edge Product copyright. I thought I'd just share this one. I plan to build another of my own design, I'll be sure to Instructable that one.
I bet they wouldn't have minded, but even if you're following somebody else's instructions, you often change things or find alternatives as you go along, which others would appreciate knowing.
