The Dual-Energy Bicycle is the only product of its kind that can be altered to be used in three different and unique ways to train all regions of the body. In addition to these three operating modes, this unprecedented bike is uniquely designed with an adjustable primary seat, an adjustable chest support, and a greater front wheel angle. Furthermore, the Dual-Energy Bicycle is carefully crafted with durable materials to ensure long term sustainability and complete functionality based on consumer preferred use and/or based on the terrain being explored.

An assisted and multifunctional ergonomic tricycle-type device for exercise, therapy, sports, recreation and alternative transportation for adults with or without disabilities, having a 4-piece chassis where part (1) is joined to part (2) by double equalizable hinge and the central part is “7” shaped, in the upper part of part (2) an adjustable front seat is installed, a cell phone holder and a Bluetooth speaker, and in the upper rear part of part (2) there is an equalizable arm extension housing an axle support of traction with hands and parts (2) and (3) of the chassis are joined to a support of an axle and a central shock absorber of the chassis and where part (2) also has supports on the front side of the drive axle with the feet and an adjustable support of an adjustable rear seat is installed on the upper rear part of part (3).

The present invention relates to a bicycle propelling device capable of transferring power to a bicycle wheel by using the gripping force of both hands. The present propelling device uses the gripping force, and thus overcomes the problem of prior art hand and foot bicycles in which balance is easily lost during driving because the prior art hand and foot bicycles require the use of the arms. The propelling device can be used together with a pedaling operation when greater power is required while the user is riding the bicycle as usual, thereby improving the running efficiency of the bicycle. Furthermore, the propelling device is formed by combining simple devices including a string and a freewheel, and thus a bicycle can maintain the original structure thereof as it is, so that it does not cause any disadvantage or difference when the user rides the bicycle by stepping on pedals in a conventional manner.

A vehicle propellable by a human comprising a front assembly having a front wheel and a pair of hand pedals connect thereto; a rear assembly having a first rear wheel and a second rear wheel rotatably connected thereto; a chest rest located between the front assembly and the rear assembly, the chest rest configured to support the chest of a rider lying forward on the vehicle; and a first foot support structure operatively coupled to rotate the first rear wheel, and a second foot support operatively coupled to rotate the second rear wheel wherein the first rear wheel and second rear wheel are independently rotated by opposite feet of a rider when said feet are within said first and second foot support, respectively.

A hybrid pump-action vehicle and therapy device may include a pumping arm attached to a lower pump-action assembly. As the pumping arm is actuated, the lower pump-action assembly moves forward and rearward in response to the pumping action and powers movement of the vehicle. The lower pump-action assembly may be releasably connected to the pump arm so that the pump arm can be disengaged from the pumping action but still be usable for steering. A motor may also be provided to provide assistance or full power to the vehicle based on a user-selectable amount of assistance. And finally, the vehicle may be configured such that it can be collapsed to a fraction of its operating footprint to enable easy transport and storage.

A foot and hand pedaled bicycle assembly that facilitates a full body working during riding includes a bicycle that has a front wheel, a rear wheel and a frame. The frame has a top member and a lower member that each pivotally extends between a seat post and a handlebar fork. The handlebar fork is urgeable toward or away from the seat post. A pair of pedals is provided and each of the pedals is rotatably coupled to the frame for rotating the rear wheel. A pair of hand cranks is provided and each of the hand cranks is coupled to the handlebar fork for steering the bicycle. Moreover, each of the hand cranks is in mechanical communication with the front wheel for rotating the front wheel when the hand cranks are cranked.
