For users with spinal cord injury, stroke or muscular atrophy, a quality lives are strongly associated with the variety wheelchair dimensions, since their body conditions will change constantly. Sadly, a traditional wheelchair has very limited adjustable features that user may need to re-purchase their chairs in order to fit their needs. The target of Flexx series is to satisfied wheelchair user in their pursuit of ”Fit”, yet, without spending huge expense.

A rainy day encounter in 1987 changed the life of Kenny Chen, Karma’s founder. One rainy day in Taipei, Kenny noticed a woman struggling to fit her father’s wheelchair into the trunk of her car. The wheelchair was heavy- difficult even for a strong man like him to lift. Kenny couldn’t forget the despair of this woman, soaked in the rain and being splashed by noisy passing traffic, or the weight and the clumsiness of her father’s wheelchair. " Couldn’t wheelchairs be better?"
