The Sparrow: the perfect city bike
Since 2013 Detroit Bikes has made and sold thousands of bicycles. During that time we've wanted to come up with the best bike for city riding. ...something simple, affordable, durable and lightweight. We think the Sparrow is the perfect city bicycle.
We teamed up with Ben Serotta, American bicycle designer for the Tour de France, and the Olympics, to create the Sparrow's frame geometry in four sizes so every rider will find their ideal fit. The Sparrow is just 22lbs, thanks to thoughtful component selection and a frame made from aircraft grade aluminium.
When you make your pledge we will send you a survey to find out which size bike you would like. We have the full bike geometry listed at the bottom of this page, but here are the height ranges we recommend:
S : 4'11" - 5'4"
M : 5'3" - 5'9"
L : 5'8" - 6'1"
XL : 6' and up
Of course, the Sparrow had to look good, so we worked with bike industry designers to develop 4 colorways to choose from.
Which after many months of product development work and testing landed us these four prototypes...
When you make your pledge we will send you a survey to ask which colorway you would like: white/red, white/blue, black/grey or black/green.
One the most important things about this bike is also one of the most subtle. Unless you've bought a bike online before, you won't know how difficult bikes can be to put together. Our goal is to free up your time and make cycling easier. Because our bikes are assembled in our Detroit factory, and shipped domestically, we can ship them in a more fully assembled state than bikes that ship assembled in China or Taiwan (99.9% of US bike sales are assembled in Asia). We've watched all kinds of 20-30 minute assembly videos where trained people try to make it look and sound easy to install brakes, but it isn't. So we did our best to get the assembly process down to the fewest possible steps. Here's a preview of those steps in a 14 second video:
Keeping your tires full is the most basic (and easiest) part of bike maintenance, but without the right tools it can be frustrating. A good floor pump makes it simple, but not everyone has one. Our solution- we've included a free Detroit Bikes floor pump for you with your bike.
Here's a video of Henry Ford II, our master builder, in the factory assembly room talking about Sparrow components.
This is Amanda, the head of our wheel building department, telling us what she likes about the Sparrow wheels she builds.
And here is Production Manager Tom talking about the innovative Sparrow packaging.
**Please note- if you can make it to Detroit and want to pick up your bike already assembled from our factory, let us know when we send out the survey and we will refund your shipping charge.
