Abstract - The main aim of this project is to style and
fabricate a cycle. generally, bicycle could be a two-wheel vehicle, which is being powered by a rider and may be steered employing a handle. it's one amongst the eco-friendlier and a cost-effective mode of transport word wide. there have been various styles of bicycle within the past history through which the prevailing form has evolved. Studies are still occurring for creating bicycling more leisurely and economical. Though bicycle could be a low-cost system that's used for travelling up to a specific distance, it needs more man power and human effort for propelling it. Hence there's always a look for a highly efficient kind of bicycle which needs less human effort for propelling it. Here introduces a replacement innovative concept. during this project the facility transmission is completed with the assistance of the Treadle mechanism by means of conventional mechanism (i.e. bicycle mechanism). The treadle mechanism is best alternative mechanism for the chains and sprocket which transmits more power from the pedal to the wheels. The design of the parts of this project is completed using the fusion 360 software and therefore the fabrication part has been meted out

1. INTRODUCTION The human powered cycle can be a tricycle that uses the step function of a stair climber with the motion and driving capability system instead of traditional bicycles. It consists of two links and three joints here we use the treadle mechanism where the connecting rods are used as a link during which one end is attached to the chain sprocket and another is attached to the stepper by using these links the oscillating motion of a stepper is converting into the move. This new concept replaces the quality bicycle. Because the stepper has oscillated, the power is transmitted from the stepper to the wheels through a treadle mechanism. This method is advantageous because of its low cost and high efficiency Also, the rider needn't apply maximum power on the stepper.

2. DESIGN CONCEPT 2.1 CAD / CAE Manufacturing today includes both computer-aided design (CAD) and engineering (CAE) as essential elements. The "traditional" method of creating engineering drawings—using drafting instruments—is no longer relevant. The traditional method was laborious and drawn out. Typically, the procedure took a long time and required several iterations before the draughtsman truly grasped what the designer desired. The planning process was transformed by CAD, and CAE advanced that.
2.2 Modeling In addition, a model is a representation of an item, system, or concept in a form other than that of the actual entity. The process of creating a model is known as modeling; a model can also be a representation of an event or the operation of an interest system. A model honours the system it portrays while being more straightforward. A model's ability to anticipate the outcome of system modifications is one of its goals. On the one hand, a model should include the majority of the significant system's prominent features and be an accurate representation of it. On the other hand, it shouldn't be so complicated that it's difficult to understand and play around with. In addition, an honest model makes a wise choice between realism and simplicity. Simulation experts advise iteratively escalating a model's complexity. Model validity is a crucial topic in modelling. Techniques for model validation include simulating the model with known input parameters and contrasting model and system output. A mathematical model created with the use of simulation software is typically also one meant for simulation research Software for modeling:
