Gyrobike

Location: Bike Town A4

Gyrowheel, a revolutionary device that adds stability and balance to bicycles for riders of all ages. Here’s the scoop: The Gyrowheel “senses” unbalanced biking and re-centers the bike underneath the rider’s weight at the point when tipping starts to occur. The force created by the Gyrowheel creates high stability at very slow speeds, whether riding straight or turning.

About the Maker(s)

With experience at consumer product startups including Method and Jetboil, Daniella Reichstetter is now CEO of Gyrobike, a rather fancy title for a natural blonde. Daniella's undergraduate degree is from Georgetown University in the oh-so-relevant field of foreign languages, and she recently completed her MBA at the Tuck School of Business at Dartmouth. When not thinking gyroscopically, Daniella enjoys outdoor activities including skiing, hiking and good old fashioned bike riding. In her more pensive moments, she wonders how many more friends she would have if she knew how to play the piano well. In the meantime, she gets by reveling in the fact that her name produces scandal-free Google search results.
