Ottobock B4 Power Wheelchair
The Ottobock B4 is a compact and robust entry level power wheelchair. The rear-wheel drive B4 offers enhanced safety and comfortable damping characteristics for outdoor use. It is also compact and manoeuvrable indoors. Permanent drive wheel suspension compensates for uneven surfaces and the wheelchair’s small outside dimension makes it easier to drive through narrow doorways and navigate in confined spaces.
Features:
Mobility base
The rear-wheel drive mobility base of the B4 is robust, durable and requires little maintenance. Driving through narrow doorways and navigating in confined spaces is made easier by the small outside dimension with a width of just 59 cm.
Drive wheel suspension
Permanent drive wheel suspension compensates for uneven surfaces and ensures enhanced safety and comfortable damping. This can be further optimised with an additional front suspension.
Anti-tipper rollers
Integrated anti-tipper rollers ensure enhanced safety and protect against damage when driving backward.
