The document discusses the design of an electric motorcycle chassis using composite material called Innegra S-Fiber. It aims to reduce pollution by switching to electric vehicles since motorcycles account for 62% of petrol consumption in India. The design process analyzed different materials like aluminum, titanium, and Innegra S-Fiber for the chassis to find the optimal lightweight yet stiff material. Innegra S-Fiber was selected as it exhibited the least deformation under loading conditions compared to other materials, allowing for a strong but lightweight chassis. This helps achieve the goal of an electric motorcycle suitable for street use with reduced weight and pollution.

The aim of this research was to
design a structurally stable and
low weight chassis for an
electric motorcycle using
composite material called
Innegra S-Fiber. With the
increasing pollution and stricter
emission norms, there is an
urgent need to switch to green
technology. In India, 62% of
petrol is consumed by
motorcycles. Therefore, there is
a major scope of reducing
pollution through electrically
driven motorcycles., Present
work attempted to design the
chassis for electric motor driven
motorcycle for street legal
transportation.
portrays a bar chart that effectively visualizes
the reduction in frame deformation across
various materials. The chart accentuates the
distinct behaviors of different materials under
the specified loading conditions. Notably, the
bar chart highlights that Aluminum (Al 6061)
experiences a higher degree of deformation,
making it the most susceptible material under
these conditions. In comparison, Titanium
(Ti6Al4V) exhibits less deformation than
Aluminum, demonstrating its superior
resistance to deformation.
Selecting the right material for the bicycle
frame was driven by cost-effectiveness and
weight considerations. While steel has been a
common choice historically, Innegra S-Fiber
was chosen due to its lightweight nature and
stiffness. Innegra S-Fiber's properties were
compared with other materials. Innegra which
means it’s a synthetic fiber made from
polyolefin polypropylene.
Based on these findings, a conclusion can be
drawn. The incorporation of Innegra S-Fiber
into the final bicycle frame design stands as an
exceptional choice. This selection not only
ensures high strength but also facilitates the
achievement of a low-weight, high-quality
bicycle frame. In essence, the project attains its
primary objective of creating an electric
commuter bicycle concept that promises a
unique blend of durability, lightweight
construction, and overall excellence.
In the context of urbanization challenges and
escalating air pollution, bicycles are
spearheading a revolution towards sustainable
transportation. However, to make bicycles an
attractive primary mode of transport, they need
to be practical and utility-focused. Unlike
recreational bicycles designed for racing and
mountain biking, utility bicycles must cater to
short commutes, carrying goods, shopping, and
everyday tasks. This research aims to design the
ideal utility bicycle, considering factors such as
material, geometry, and strength.
