Love single speeds, and love coffee – what if there was a way you could combine your two loves to produce the most artisanal cup of coffee around? That’s right, we’re talking about affixing a grinder to your singlespeed bicycle to obtain the freshest grounds possible all by hand foot.

Created by Dan Hill and Dave Buonaguidi from London ad agency Karmarama, the Gear Grinder is the first chain driven coffee grinder that attaches to the seat say of a single speed bicycle.  According to Hill, “As far as I’m concerned this is up there with the discovery of fire and the creation of the internet in its value to the people of earth.” Buonaguidi added that, “I also believe that hand or foot grinding is better than machine grinding because the imperfections in the ‘analogue’ grinding process creates an unevenness which adds to the subtle notes of the coffee flavor.”

The concept is sound, running a flip flop hub with the fixed gear attached to the grinder. Load up the hopper with up to 20g of your favorite bean, and pedal way until ground. Pedal the bike, and the hub would power the chain theoretically attached to the grinder. Perfect for those times you want to get up and spin around the block a few times before having your usual cup of joe. According to the website, the Gear Grinder will be offered in three finishes, chrome, brushed steel, and metallic mocha.

If this isn’t a bit of satire, it probably should be with its £350.00 ($568!!) price tag. Maybe if that price was for the whole bike with the grinder attached…


  1. I was a hipster in college 15 years ago. When will the youths think of something new and unique? Stop following in our footsteps the path is very well beaten.

  2. As a college student, I could use one of these to get myself invited over to a girl’s dorm to “grind” a cupa coffee. btw.. I’m broke, maybe Dan & Dave will help me out for Christmas?

  3. I love that the imperfections in the grind are supposed to improve the coffee, contrary to what I’ve learned about coffee grinders and making from every other source.
    It’s like saying that uneven welds add to the character and uniqueness of a bike.

  4. It makes a change from the umpteen bottle openers I ‘ve seen but it seems to prove the theory that hipsters will buy almost anything that has a slick website and a fancy back story.

  5. It seems the bike side has taken care of its side. However, I’m sure the coffee side will chime in with technical reasons why tumbling the beans in such a brutal manner pre-pour actually degrades the quality of the resulting brew.

    Maybe you can alter the gear ratio of the grinder to suit the style and grind desired? (“For a fine Arabica French press brew, run a 22×12; for course espresso blends in drip systems, run 18×36.”)

  6. a chain tensioner?! I’m calling hipster-foul. No way you can grind a decent cup of coffee with a chain tensioner and brakes. Obviously these guys are not from Portland.

  7. Does it make a ‘Special Blend’, incorporating all the flavor of road salt and black snow?

    I am also thinking that someone – if they cared – could round up spare parts, a used grinder from the Goodwill and Home Depot and make this for about $30?

  8. well, it sure beats the prototype version they had. The stay mounted steel cannister is a nice touch.
    Originally, they had me putting gravel and coffee beans in a ziploc baggie (recycled, of course). The baggie was stuffed in my shorts and I was told to do repeats on a hill climb with waterbars. I was like, What the hell, but the grinds turned out okay and my chamois lost that funky odor. two birds – one bean. nice, but this is better anyway. much better.

  9. It would also work great at home if you had an electric powered wind trainer to mount your bike on, maybe they could invent one of those too.

  10. When will people that use a chain tensioner get it the right way?! why would you pull the chain down, and thus away, from tooth engagement?? A derailleur pulls up and then back. Horizontal dropouts or GTFO!

  11. This thing is freakin’worthless unless it is attached to a Bamboo cargo bike built by Indonesian Pygmies using bamboo cut by the teeth of Panda bears and bonded with glue made from the rendered bodies of endangered monkeys.
    Until then I am not interested.
    We want Carbon bike stuff and more gears. What about that don’t you understand?

  12. @Charlie, you could ride on the fixed side and the freewheel, spinning “backwards,” would drive it just fine. You just need the flip flop hub for the extra gear, unless you substituted in a centerlock or 6-bolt mount cog.

  13. Sounds like a great invention! Just wondering how durable it is? When I am shredding the gnar and lay it down, will this hold up? Does the lid stay on if you are doing 6ft drops? More info needed. Does it work with 27.5? Really too little info so far, but at that price might just give it a shot.

  14. from their site;
    “the imperfections in the ‘analogue’ grinding process creates an unevenness which adds to the subtle notes of the coffee flavour.”

    those “notes” created by the “unevenness” are called bitters or in trade talk a “sink shot”.

  15. If they could add a heater, perhaps powered by a dynamo in the front hub, or even just the brakes, you could readily build an espresso machine using a pressure vessel. And if you had a desalination plant, you wouldn’t even have to add water…
