Dear Sam I would like you to know that your invention is awesome! It was easy to fit with good clear instructions. It worked perfectly first go. It will now enable me to pull away on my trike on any incline by dropping the ‘front cog’ while stationary. That used to be a real problem… Read more

“I am pleased as punch with my Patterson drive. A common problem when I bike in the winter is my derailleurs gumming up and failing. The Patterson has a sealed mechanism that protects it.

Hi Sam, I wrote you some time ago with various questions about the PM, which I use in combination with a NuVinci N360. This email is an update. In June I flew my little folder from Kuala Lumpur, where I live, to Bangkok where I started my journey to Chiang Mai, in northern Thailand. Th… Read more

  Hello, I recently installed your Patterson on my recumbent trike and it is AWESOME. I will say though that the ability to get a different gear ratio would be very nice, I saw on an online forum that you were thinking of offering up different chainrings? I would love something in the 32/51 … Read more

Here is an initial pic on my Santa Cruz Blur, XC. Just back from 7 days riding in Mammoth…still love the transmission, although I must admit that most of the riding was slow, steep, technical riding, where I mostly used the low (1:1) range only. Fun stuff.

Plenty of time on my Metro/N360 bike. I’d have to consult my records but I am approaching 3,500 miles on it and there has been no issues except adjusting the cable tension. I do mostly utility or social riding on this bikes through easy to moderate hills and terrain, and regularly loaded down wi… Read more

Since I originally emailed, I purchased an FSA Patterson Drive and installed it on my Surly Big Dummy with an old XTR 9 speed rear derailleur (11-34) and absolutely love it. It’s great being able to drop into the low gear while stopped at stop signs, the much cleaner looking installation and t… Read more

Thanks again, …for hooking me up with the Patterson drive. Worked great on the way home. Smooth and pleasant shifting, I’m happy!  Have a nice week off! You’ve done a great thing.

One really cool thing, …is that the removal of the front derailleur (along with the removal of the big ugly chainrings) gives a bike a much sleeker look.

I just picked my bike up from the shop where I had it installed and that is one sweet piece of engineering. It’s way better than any of the prototypes, and not only performs well, it looks great too. Plus, my pants wont get caught on the chain anymore. Nice bonus in case bellbottom pants come… Read more
