Abstract
An observation wheel type ride includes a wheel, multiple passenger cabins supported by the wheel, a drive mechanism for rotating the wheel about its rotational axis, and a support structure that supports the wheel. The wheel furthermore includes two first bearings, provided with a first bearing locking mechanism, and two second bearings, provided with a second bearing locking mechanism. Each bearing locking mechanism can selectively be converted between a locking condition, in which it prevents rotational movement of a bearing inner ring relative to a bearing outer ring, and an unlocking condition, in which it allows for rotational movement of the first bearing inner ring relative to the first bearing outer ring. Providing the second bearings allows for rotational movement of the wheel about the rotational axis of its support axle when the first bearing locking mechanisms are in their locking condition.
