Why didn't Segway work?

What happened to Segway?

2001-12

PRODUCT LAUNCH

Segway PT officially launched to the public at $4,950–$5,500 per unit; first-year sales reach fewer than 6,000 units against internal projections of 10,000 units per week, a catastrophic miss of over 99%

Documented cause

Segway launched in 2001 with legendary hype: Steve Jobs called it 'bigger than the internet,' John Doerr predicted it would reach $1B in sales faster than any company in history. Reality: in its first year, Segway sold fewer than 6,000 units against projections of 10,000 per week. The product was real and it worked — but it required infrastructure cities weren't willing to build, retailed at $5,000+, and occupied an awkward gap between bicycle and pedestrian. It was too slow for roads, too fast for sidewalks, and too expensive for casual use. Dean Kamen spent 10 years and $100M solving a problem most people didn't have.

Lesson

“Pre-launch hype from credible people is not validation. Real adoption requires infrastructure, price accessibility, and a clear behavioral replacement — none of which Segway ever secured.”
