A cargo cycle includes a frame, a plurality of wheels and a rider seat assembled on the frame, and a passenger compartment supported on the frame. The passenger compartment includes a plurality of side walls and at least one passenger seat disposed inwards of the side walls. The passenger seat has a plurality of reclining positions reclined at different angles relative to the side walls. The passenger seat includes a back support and a seat portion. The back support has a folded orientation in which it is folded down parallel to the seat portion and forms a cover of the passenger compartment.

An apparatus including a bicycle frame including a drive side chain stay. The drive side chain stay can include a drive side chain stay chamber, an inside chain stay cutout, an outside chain stay cutout; and a dropout. The drive side chain stay can be configured such that a chain of a bicycle including the bicycle frame can be inserted through the inside chain stay cutout, the drive side chain stay chamber, and the outside chain stay cutout without breaking the chain.

A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt running between front and rear pulley rollers is formed with a low friction running surface of transverse aluminum, wooden, plastic, rubber or carbon fiber slats attached to each other in a resilient fashion. An essential feature of treadmill is the concave shape of the upper portion of the belt running surface, the treadmill configurations ensure that this shape is maintained during actual use. These configurations prevent the concave upper running surface portion from being pulled taut into a flat shape between the front and rear pulley rollers. The slats of the treadmill each have an end view crossectional I-beam shape, for strength and stability of the slat positioned upon the treadmill belt.

A modular cargo vehicle for transportation of cargo by a rider. The cargo vehicle includes a tow cycle, a front cargo module, and a trailer cargo module. The tow cycle has a rider seat, a front axle with a front wheel, a rear axle with one rear wheel, and a pedal crank to facilitate driving of the tow cycle by the rider via a pedal crank. A rear end of the front cargo module is coupled to a front end of the tow cycle. The front cargo module has a front axle with a front wheel, a cargo-receiving area, and no rear axle. A front end of the trailer cargo module is coupled to a rear end of the tow cycle. The trailer cargo module has a cargo-receiving area and an axially central axle with two wheels.
