Abstract
A mid-wheel drive wheelchair can have various suspensions for the drive wheel such as a rigid connection to the wheelchair frame or a resilient connection thereto. The wheelchair has at least one anti-tip front wheel stabilizer, which is rigidly, i.e. non-resiliently, connected to the frame and accordingly the wheelchair frame moves up and down with the anti-tip wheel upon encountering a bump, hill, etc. The height of the anti-tip wheel above the travel surface is adjustable and accordingly the wheel can be set to a specific height.
