Alright folks, let me tell you about this crazy project I tackled – building a Trex Motorcycle! I know, sounds wild, right? Well, it was!

It all started when I stumbled upon some blueprints online. I was immediately hooked. I mean, a three-wheeled, open-air vehicle with a motorcycle engine? Sign me up! I knew it would be a huge challenge, but I was ready to dive in headfirst.
The Frame:
- First things first, I needed a frame. I spent weeks researching different types of steel, welding techniques, and suspension systems. Finally, I decided on a tubular steel frame, which I figured would be strong and relatively lightweight.
- I rented a tube bender and got to work, carefully following the blueprints. Let me tell you, bending those steel tubes was a serious workout! There were definitely a few moments where I thought I’d messed up, but I managed to pull through.
- Welding the frame together was another beast altogether. My welding skills were… rusty, to say the least. I practiced for hours on scrap metal before even attempting to weld the actual frame. It wasn’t pretty, but it held!
The Engine:
- Next up was the engine. I managed to snag a used motorcycle engine from a local junkyard. It was a bit rough around the edges, but with some TLC, I knew I could get it running.
- I spent days cleaning and rebuilding the engine, replacing worn parts, and tuning it up. It was like putting together a giant puzzle, but with greasy fingers and the constant threat of electric shock!
- Finally, the moment of truth – I hooked up the battery and hit the starter. After a few coughs and splutters, the engine roared to life! It was music to my ears.
Putting it All Together:
- With the frame and engine sorted, it was time to start putting everything together. I installed the suspension, the wheels, the brakes, and all the other bits and pieces.
- Wiring was a nightmare. So many wires, so little space! I spent hours tracing circuits and connecting wires, double-checking everything to make sure it was correct. I probably aged 10 years during that process.
- The bodywork was another challenge. I decided to go with a simple, minimalist design, using fiberglass panels that I molded myself. It wasn’t perfect, but it looked pretty damn cool, if I do say so myself.
The Big Reveal
After months of hard work, sweat, and tears, the Trex Motorcycle was finally finished! I couldn’t believe I’d actually done it. It was rough, it was raw, but it was mine.

I took it out for its first test drive, and let me tell you, it was an experience. The wind in my hair, the roar of the engine, the feeling of freedom – it was incredible! Sure, it wasn’t the smoothest ride, and there were a few quirks to work out, but it was a blast.
This project was definitely one of the most challenging things I’ve ever done, but it was also one of the most rewarding. I learned so much about engineering, fabrication, and problem-solving. And I ended up with a pretty awesome machine to show for it!
If you’re thinking about tackling a similar project, my advice is – go for it! It won’t be easy, but it’ll be an adventure you’ll never forget.
