Thanks to its frame structure which is designed for extreme loads and the simple setting options for seat height and centre of gravity, the SPEEDY A2 model offers maximum mobility in daily life.
The frame structure is specifically designed to suit the attachment of stair climbers such as the scala mobil model (Ulrich Alber GmbH) and the S-MAX (AAT Alber Antriebstechnik GmbH). Stair climbers may be attached with a minimum seat width of 36 cm. This combination meets the wheelchair user's need for independence and mobility in daily life without having negative repercussions for the weight, the handling characteristics and the manageability of this wheelchair.
