Where can I get one? How much are they?
Sorry, but the Speed Vest is not yet available commercially. If you’d like to be updated, or if you’re a bicycle advocacy organization and would like to use it for outreach and education, send us an e-mail: info@speedvest.com.
 
How does the vest work?
In a nutshell, it uses a sensor on your wheel to send a signal to a microcontroller that then turns the numbers on and off on the vest. For a lot more detail, check out Mykle’s site.
 
Who made this?
Brady Clark and Mykle Hansen. Brady conceived of it, Mykle engineered it and they built it together during a few all-nighters in Minneapolis, MN.
 
Why did you invent this?
Have you ever outpaced cars and been honked at? Had a car almost wipe you out while making a turn? The Speed Vest was invented because we were curious to know if putting more information in front of drivers might change their awareness of bicyclists. That, and we suspect a lot of people don’t realize that an average person can bike 10-15 mph (15-25 km/h). 
 
Can you prove it makes you safer?
No, but it does make you more visible. We’d be really interested in lending it to a research project if you are the measuring type.
 
What’s the highest number it displays?
Up to 70 miles or kilometers per hour.
 
Where can I see it in action?
In September we showed it off at the Pro Walk / Pro Bike conference in Seattle, Washington. We had a lot of fun, and would love an excuse to bring it to your town! E-mail us at info@speedvest.com.

What’s that funky music in the video?
It’s called “Do the Spoke” [iTunes] and is from a band Mykle is in called The Golden Greats.
