We had a great day yesterday at the Ferris Wheels Bike Shop in Jamaica Plain Boston. We fit the horn to a brand new Yuba cargo bike and sent a few people out to test it live on the streets.
Jamaica Plain has a strong bicycle culture with lots of bicycle commuters and bikes that carry kids. A few backers came out to meet us, excited to get their horns and stressing how important safety is to them.
Dan graciously offered to do a photo-op, thanks!
Here is a closeup of the button, it is really easy to brake and maneuver while honking our horns.
