Segway's prototype wheelchair crashed during a demonstration at the CES tech show.

Axar.az reports citing foreign media.

The S-Pod - a self-balancing electric wheelchair - was being tested by a journalist at the time. The rider had accelerated the vehicle before accidently crashing into a wall.

Its maximum speed is 24mph (38km/h). The company said no one was injured.

The crash made the S-Pod unavailable for further demos, but analysts say the company should not face lasting damage.

"In no way is a [malfunction] a total loss. It is still a sign to the public that the company is close to the finished product," said Ross Rubin, principal analyst at Reticle Research.

The S-Pod is designed to be driven in enclosed spaces such as airports, theme parks and work campuses.

Segway's director of marketing Jeff Wu told the BBC the concept model did not have a safety belt, but that his company intended to add one.
