- Appearance
The profile of the transmission belt is created as per the dimensions in the front plane, the belt is given thickness of 3.5 mm. Once the sketch is completed the belt is extruded. The square edges are given fillet. The transmission belt is made out of mate rubber.
- Kick stand:
Kick Stand is a supporting structure provided to a bicycle or motorcycle to help it stand in a vertical position when stationary.
Features used:

- Extruded Boss/Base
- Fillet
The loft feature is used to create the kick stand. Two ellipses are created on the right plane, one at the top end and another one at the bottom end of the kickstand. A path is sketched on the front plane which joins the center points of the two ellipses created before using a pierce relation between the center of the ellipses and the path. Using a loft, the body of the kickstand is created. Elliptical dome features are used to create the rounded end of the kickstand. A slot with an extruded boss is created at the top end of the stand using which it is connected to the chassis. At last fillets are provided to the sharp edges of the stand. Chrome plate appearance is applied to the kickstand.
- Front Fender
Front fender is the cover for the front wheel. It protects from muds, sands, small stones, etc on the road.
Features used:
- Revolve Boss/Base,
- Split,
- Trim,
- Shell
A sketch is created in the front plane using a three point arc and offset it to meet the thickness of the fender. Create an axis at the origin. Using a revolve boss the required front fender is created. Two different sketches are created in the top plane and the right plane to cut the front fender into required shape. Fillets are created on the sharp edges of the fender Desired appearance is applied to the fender.
- Rear Fender:
Rear fender is the semi cover for the rear wheel. It protects from muds, sands, small stones, etc on the road.
Features Used:
- Revolve Boss/Base,
- Fillet,
- Trim,
- Shell.

- Combine
A main profile of the chain is created using three point arc and tangent relations between the arcs using the given dimensions. Create two throwaway sketches which are used to create the inside and outside links of the chain. The plates of the chain links are extruded using the throwaway sketches and the connecting pins are created using the same sketch. Only one side of the plates of the chain links are created. The created chain links are pins then populated on the main sketch using the linear pattern and circular pattern features. All the chain link plates are then mirrored on the front plain. All the components of the chain are combined as a single part using a combine feature. Chrome steel appearance is applied to the chain.

Initially the rim is created by sketching on the front plane and the revolved extruded using an imaginary axis at the origin. A spider web design of the Rim is created on the front plane and is extruded using midplane extrude feature. And this spider web is circular patterned to required numbers and the Rim is completed. The spider web spokes and the rim are combined to form a single solid body.
For Rotor sketch on the front plane and extrude it to the required dimensions. Create the necessary holes using circular pattern.
For Caliper create a profile using lines and circles and remove the unwanted sketch and midplane extrude the caliper profile. Provide necessary fillets and chamfers to complete the caliper.
The Tyre sketch is created by converting entities of the Rim. And the Tyre is revolve extruded. Later profiles are created on the surface of the Tyre to give the gips to the tyres.
Separate appearances are applied to each part of the wheel.

Again using the inserted picture and choosing the front plane, the base of the engine is created using three point Circle and lines (using tangency properties) and extruded to required dimensions. Again using the same sketch extrude the two circles. Again on the front plane create the twin engines in the V-shape. Create the sketch for pulley and create the pulley using revolved extrusion. Create the cylindrical part in the front of the engine on the front plane. Using the curves created and projected curves, create the profile of the exhaust pipes and create the swept boss feature. Then the spark plugs are created at the end. Apply the appropriate material to the engine.

Now mirror the created part of the tank and knit the entire surface together Now apply appropriate materials to the gas tank and the seat.
Assembly of the American Chopper
All the designed components are taken into the assembly section in Solid Works and using different mating.
Features used for mating:
- concentric,
- coincident,
- parallel,
- Limit Angle.
The entire assembly of the American Chopper is created. After assembly the Decals are applied to the Chopper. Once the application of the decals is finished, the assembled motorcycle is taken into Solid Works Visualize or using Photo-view 360. Here various aspects such as camera, external lightnings, background scenes, etc. are taken into consideration before the creation of the final rendering. The final rendered images of the American Chopper are derived.
Conclusion:
Thus the American Chopper was modelled, assembled and rendered in solidworks software.
