Product Description
Compact and robust
The B4 with rear-wheel drive offers enhanced safety and comfortable damping characteristics for outdoor use while still being 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.
Like all models in the B Series product line, the B4 features a modular design and offers a high level of flexibility. The available options and features for the mobility base, seating unit and control device result in a modern and customised fitting. High-quality components such as the variably adjustable seat (VAS) or the TEN° control device can also be selected.
