What stands out is how simply it all seems to come together. Markku has always been interested in bike design and has studied “the details of suspension design, details of geometry design, details of the material, details of the bicycle parts, possibilities of different fabrication techniques etc” but he has no official training. Even the suspension system, often a stumbling block for budding designers, was no bother with Markku plumping for a proven winner – a four bar linkage with 135mm rear travel – why reinvent the wheel?
In fact, the hardest part of the process seems to have been finding and working with a Chinese fabricator. He says: “It’s not hard to find a frame fabricator in China but it’s not easy to find the correct one. I wanted to find a small but reliable fabricator with reliable and fast customer service in English language and experience in full suspension design. I spent hours browsing through different forums then I sent requests to few of them and chose the right one based on pretty much my gut feeling.
“It is also very important to prepare yourself for the fact that the design process is not over when you send your design to the fabricator. That’s when it really begins. Anything can, and something will, go wrong during the process, so it’s really important to find a fabricator that you can trust and who is easy and fast to communicate with.”
So the big question is, can anyone do this? Well, yes and no. In theory, anyone with a decent enough computer can pirate a CAD program and get cracking but Markku has had to put in a lot of hours of research, design and fettling into his Pässilä. As for the price, Markku reckons the frame cost him under two grand which, to be honest, is pretty good for titanium but that doesn’t factor in all the labour it took to come together.
A bike from a recognised brand may not exactly match your needs but it’s, much easier to get hold of… and you know it’s definitely going to work when you put down your hard earned dough.
The bike industry probably shouldn’t be shaking in its boots just yet but Markku has ended up with a very special, and totally unique, bit of kit.

I have also some new product ideas brewing up in my head which I might want to try out.
