The disclosure provides a door system for a vehicle having a roll cage. For example, the vehicle may be a multi-use vehicle. The door system may include a door hinged to a vehicle body and releasably engaged to the vehicle body in a closed position by a latch. The door system may include a net extending from the door to the roll cage. The net may be releasably attached to the roll cage by a clip actuatable by a cable connected to the latch.

A method for replacing a roll cage of an off-road vehicle is provided. The off-road vehicle has a frame and the roll cage affixed to the frame. The frame has a plurality of roll cage supports. The roll cage has a plurality of legs, and each of the legs is welded to a respective one of the roll cage supports of the frame. The method includes cutting off the roll cage from the frame, providing a replacement roll cage for removably affixing to the frame, positioning the replacement roll cage onto the frame such that legs of the replacement roll cage are supported on the roll cage supports, aligning an opening of a mounting flange of each leg of the replacement roll cage with a corresponding opening of each roll cage support, and fastening the legs of the replacement roll cage to the roll cage supports.

A method of assembling a frame for a personal electric vehicle includes assembling a safety cage defining an occupant interior by attaching together a plurality of tubular members including at least two left pillars and two right pillars each having lower end portions positioned along respective sides of the occupant interior. The method further includes positioning a floorpan adjacent a bottom of the occupant interior, the floorpan having a floorpan left side adjacent the lower end portions of the left pillars and a floorpan right side adjacent the lower end portions of the right pillars. Thereafter, the method includes fixing a left inboard surface of each left pillar to the floorpan left side and fixing a right inboard surface of each right pillar to the floorpan right side for securing the safety cage to the floorpan.

A tube connection arrangement includes a tube having a cutout configured such that a part-tube portion adjoins a full-tube portion of the tube. An insert has a first portion for being received in the full-tube portion of the tube and has an external circumference adapted to the internal circumference of the full-tube portion, and a second portion for being received in the part-tube portion of the tube. The second portion has a curved contour adapted to the internal contour of the part-tube portion, an opposite abutment side. In the inserted state of the insert, the abutment side of the second portion is directed towards the cutout and through-openings in the part-tube portion and in the second portion of the insert are aligned in order to enable a fastening element to be fed through.

A utility vehicle capable of off-road travelling includes a cabin, a floor panel including a floor tunnel, an air blower and a duct. The duct includes a first end part that is connected to the air blower, a second end part including an opening part open to a rear half portion of the cabin, and an extending part that extends between the first and second end parts. The extending part includes a first part extending in the front-rear direction. The whole duct is arranged above the floor tunnel.

A vehicle includes: a frame including a roll cage, a motor connected to the frame, a driver seat connected to the frame, and a roof extending at least in part above the driver seat. The roof includes an upper surface and a lower surface. At least part of the roof is pivotably connected to the roll cage about a roof pivot axis so that the at least part of the roof is pivotable from a closed position to an open position. In the closed position, the at least part of the roof covers a roof opening defined by the roll cage, and in the open position, the at least part of the roof at least partly exposes the roof opening.
