- RockMachine Blizzard 650b/29er Downhill machine Whizz learns how to pedal up
Gravity disciplines require progressive suspension, durability, stable and slack geometry. Trail and hard core XC bikes need something extra - lightness and speed even when climbing. That is why trail bikes became so popular recently and with bigger wheel diameter get even more racy. BicycleHeads bring to life next generation of RockMachine’s suspension. Linkage remains the same (as to Whizz FR/DH), shock moves into front triangle and the shock curve is tuned by using Smart-link assembly.

- Patriot EVO Prototype Enduro geometry – 140/160mm of travel … what else?
Bike development takes time and some babies need to grow up slowly. That’s why here is the non-production version of Patriot EVO. 140/160mm suspension setup based around longer shock strokes brings super pedaling agility and suspension sensitivity.
Check back later production versions!

- Handmade COOWA Shoofly 7+ / FatDaddy / Hoofer 4x / HarumScarum / Mr.Sister ...lots of CNC...memories
Years 2006 – 2009...designing, welding, testing, living in workshop. That was the era of COOWA bikes. Good experience and basis for future evolution of BicycleHeads.
