Attached is a pic of my touring/commuter. It’s a Surly Crosscheck, with your Metropolis crank, 3speed Shimano Nexus, and Shimano generator hub supplying power to the E3 front light, rear light and headset charger with an Adamo saddle.
I’ve put at least 6k miles on this bike with your drive train and the Metropolis has not failed me once!!
Thank you again for the spare parts. Best regards ,
(Nice bike Julio! Is the weight balance better with th… Read more
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 if I pulled up in high gear on the old front derailleur at traffic lights, …with a Mac truck snarling behind me.
Finally it looks so much better than the cog system that looked like a medieval weapon on the front o… Read more
Dear Mr Patterson,
So, Mr.Patterson, thanks for helping my wife install your internal crank invention, the Metropolis Patterson crankset, on my Soma Saga. And also thanks for the parts that you sent her. What a wonderful invention! As a semi-old man who mostly likes to ride around our retirement park and also doesn’t like too many c… Read more
Dear Mr Patterson,
Ted did an excellent job! His buddies Mike in New Orleans and Michael in Mt. Vernon (luxury car mechanic) helped and it’s all good.
I’ve been riding it everyday and playing around with the gears. Yay!!
I took a bike ride on Sunday afternoon and here is me riding along the Bronx River bike trail.
Earlier on Sunday, I had an older Italian gentleman who makes & sells handmade mozzarella & provolone cheese at the Tuckahoe farmers market google-eye my bike with envy. He said to m… Read more
“Sam, I do a lot of road biking in the summer probably travel about 2500 miles in 4 months if not more .. I have an 8 speed sturmy archer internal hub on my terratrike rover.. before I got your patterson crankset I maxed out my requmbent. I could go no faster or get any harder work out.. I averaged a cruising speed of about 17 mph and now that I have your crank-set I have a cruising speed of about 21mph .. I love the crank …” – Tom Davis, Wounded Warrior
“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. Another reason I bought the Patterson drive is to give my bike, which has an electric motor, very high gearing so that I can pedal with the motor even at high speeds.”

The Experimental Vehicles Program at Middle Tennessee State University utilized your transmission cranksets in our NASA Human Exploration Rover Challenge Vehicle last year, where our rover was chosen by NASA engineers to receive the coveted Neil Armstrong Best Design Award.
We are currently in the process of building a new Rover for the 2015 competition, and would like to know if you would be willing … Read more
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. The trip of 800 km lasted 9 days, 730 km and 8 days of which were on the bike. Aside from a hot and steamy ride past some incredible countryside, the real news is that I experienced not one mechanical issue. The P… 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
range or so…
I work at Coventry Cycle Works in Portland Oregon.
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.
