INTRODUCTION:
American Chopper Motorcycle:
Choppers are custom motorbikes that first surfaced back in California, USA in the 1950s. They are iconic bikes and still have a dedicated set of enthusiasts around the world. They are perhaps the most extreme form of custom bikes that have a rather stretched out appearance. For this purpose they have modified steering angles and elongated forks that give it the singular appearance that they are known for. They are normally modified or “chopped” from regular motorcycles and that is where they get their name from.
They include a couple of modified Harley Davidsons, a Billy bike and a Captain America. The choppers although are iconic American bikes, they do have enthusiasts around the world. They have a rich history as well that is part of the amazing automobile revolution.

DESIGN TOOL: SOLIDWORKS
INTRODUCTION
The Solid works CAD software is a mechanical design automation application that lets designers quickly sketch out ideas, experiment with features and dimensions, and produce models and detailed drawings. This document discusses concepts and terminology used throughout the Solid works application. It familiarizes you with the commonly used functions of Solid works.
CONCEPTS:
Parts are the basic building blocks in the solid works software. Assemblies contain parts or other assemblies, called subassemblies. A Solid works model consists of 3D geometry that defines its edges, faces, and surfaces. The Solid works software lets you design models quickly and precisely.
Solid works models are:
- Defined by 3D design
- Based on components
3D DESIGN:
Solid works uses a 3D design approach. As you design a part, from the initial sketch to the final result, you create a 3D model. From this model, you can create 2D drawings or mate components consisting of parts or subassemblies to create 3D assemblies. You can also create 2D drawings of 3D assemblies. When designing a model using Solid works, you can visualize it in three dimensions, the way the model exists once it is manufactured.
COMPONENT BASED
One of the most powerful features in the SOLIDWORKS application is that any change you make to a part is reflected in all associated drawings or assemblies.
SKETCHES:
The sketch is the basis for most 3D models. Creating a model usually begins with a sketch. From the sketch, you can create features. You can combine one or more features to make a part. Then, you can combine and mate the appropriate parts to create an assembly.
From the parts or assemblies, you can then create drawings. A sketch is a 2D profile or cross section. To create a 2D sketch, you use a plane or a planar face. In addition to 2D sketches, you can also create 3D sketches that include a Z axis, as well as the X and Y axes.
There are various ways of creating a sketch. All sketches include the following elements:
ASSEMBLIES:
You can combine multiple parts that fit together to create assemblies. You integrate the parts in an assembly using Mates, such as Concentric and Coincident. Mates define the allowable direction of movement of the components. In the faucet assembly, the faucet base and handles have concentric and coincident mates. With tools such as Move Component or Rotate Component, you can see how the parts in an assembly function in a 3D context. To ensure that the assembly functions correctly, you can use assembly tools such as Collision Detection. Collision Detection lets you find collisions with other components when moving or rotating a component.

- 2. Kickstand or Side Stand:
A kickstand is a device on a bicycle or motorcycle that allows the bike to be kept upright without leaning against another object or the aid of a person. A kickstand is usually a piece of metal that flips down from the frame and makes contact with the ground. It is generally located in the middle of the bike or towards the rear. Some touring bicycles have two: one at the rear, and a second in the front

4.Rear Fender:
Rear mudguards are generally fixed behind the saddle, above your back wheel. For mountain Biking, go for a model that fixes onto the seat post. This kind of mudguard protects you from mud a bit less, but mud is lesser of two evils the advantage is increased sturdiness so it won’t touch the wheel at all.

5.Chain
Chain drive is way of transmitting mechanical power from one place to another. It is often used to convey power to the wheels of vehicle, particularly bicycles and motorcycles it is also used in a wide variety of machines besides vehicles.
Most often, the power is conveyed by a roller chain known as the drive chain or transmission chain, passing over a sprocket gear, with the teeth of the gear, with the teeth of the gear meshing with the holes in the link of the chain

6.Oil Tank:
An oil storage tank is a container or reservoir that temporarily holds oil in the various stages of processing into other oil products, or before it is used or consumed. Based on location, oil storage tanks may be classified as surface or above ground, semi subterranean and subterranean or underground tanks.

8.Front wheel:
A bicycle wheel is a wheel, most commonly a wire wheel, designed for a bicycle. A pair is often called wheel set, especially in the context of ready built "off the shelf" performance-oriented wheels. Bicycle wheels are typically designed to fit into the frame and fork via dropouts, and hold tires. The rim is commonly a metal extrusion that is butted into itself to form a hoop, though may also be a structure of carbon fiber composite, and was historically made of wood. Some wheels use both an aerodynamic carbon hoop bonded to an aluminum rim on which to mount conventional bicycle tires. The cross-section of a rim can have a wide range of geometry, each optimized for particular performance goals. Aerodynamics, mass and inertia, stiffness, durability, tubeless tire compatibility, brake compatibility, and cost are all considerations. In this Front wheel of chopper are always larger than the rear wheel with narrow section as compared to the latter. The front wheel of choppers has narrow section meaning narrow surface contact.

9.Rear wheel:
A bicycle wheel is a wheel, most commonly a wire wheel, designed for a bicycle. A pair is often called wheel set, especially in the context of ready built "off the shelf" performance-oriented wheels. Bicycle wheels are typically designed to fit into the frame and fork via dropouts, and hold tires.

The cross-section of a rim can have a wide range of geometry, each optimized for particular performance goals. Aerodynamics, mass and inertia, stiffness, durability, tubeless tire compatibility, brake compatibility, and
cost are all considerations. The rear wheel also houses a disc brake rotor and its caliper and specifically a chain sprocket to drive the wheel using power transmitted from engine.
Rear wheel of choppers are generally smaller in diameter than the front wheel. The tyres have a broad section meaning broader surface contact, heavy load carrying capacity and greater grip

10.Front Fork:
A motorcycle fork connects a motorcycle's front wheel and axle to its frame, typically via a yoke, also known as a triple clamp, which consists of an upper yoke joined to a lower yoke via a steering stem, a shaft that runs through the steering head, creating the steering axis. Most forks incorporate the front suspension and front brake, and allow the front wheel to rotate about the steering axis so that the bike may be steered. Most handlebars attach to the top clamp in various ways, while clip-on handlebars clamp to the fork tubes, either just above or just below the upper triple clamp.
The fork and its attachment points on the frame establish the critical geometric parameters of rake and trail, which play a major role in defining how a motorcycle handles and dives during braking

- Chassis:
A motorcycle frame is a motorcycle's core structure. It supports the engine, provides a location for the steering and rear suspension, and supports the rider and any passenger or luggage. Also attached to the frame are the fuel tank and battery. At the front of the frame is found the steering head tube that holds the pivoting front fork, while at the rear there is a pivot point for the swing arm suspension motion. Some motorcycles include the engine as a load-bearing stressed member; while some other bikes do not use a single frame, but instead have a front and a rear sub frame attached to the engine.

- Engine:
A motorcycle engine is an engine that powers a motorcycle. Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used. The engine consists of piston-cylinder arrangement which powers the motorcycle. The IC engine houses air intake, exhaust outlet and fuel intake ports.
In this chopper v-twin engine is used with four mounting points to the chassis

13.Fuel Tank:
A fuel tank (also called a petrol tank or gas tank) is a safe container for flammable fluids. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine system in which the fuel is stored and propelled (fuel pump) or released (pressurized gas) into an engine. The fuel tank of this American chopper is made to house a seat and fit to the chassis centrally with the mount.

ASSEMBLY:
American Chopper Motorcycle Assembly:
While in an assembly, you can create features that exist in the assembly only. You determine which parts you want the feature to affect by setting the scope. You can create a pattern of assembly features in the same manner as you create a pattern of features in a part.
Use an assembly feature if the feature is added after the components are actually assembled and the feature affects more than one component. For example, use assembly features when you need to represent material-removal operations that are done after the components are assembled.
When you want to add a feature to a single component in an assembly, it is better to create the feature in the part rather than the assembly. To do so, you can do one of the following:
- Edit the part in context.
- Create the feature in the assembly and then propagate it to the part by selecting Propagate to part in the Property Manager.
While it is not a requirement, it is good practice to fully define the positions of the components of the assembly, or fix their locations, before you add assembly features. This helps prevent unexpected results if the components are moved later.
