Team LUMINOUS from Government Engineering College, Modasa participated in the SAEINDIA Efficycle event of 2014. They designed a hybrid-electric trike using a tadpole layout with a recumbent seating position. Over 225 teams participated virtually, with only 90 selected for the main event. There, teams' designs were evaluated on technical inspection, static events, and dynamic tests like acceleration and endurance. Team LUMINOUS placed 17th overall nationally after passing all tests, gaining valuable experience in collaborative design, manufacturing, and competition.

Abstract
Nowadays, the use of hybrid system increases and it gives more benefit to people and
nature in the cost of fuel and also in pollution. As per this concept, Trike with Hybrid
System is designed in Tadpole Style. This is not only for SAEINDIA EFFI-CYCLE
event trike but also a dream to make something better as per rulebook of Effi-Cycle
and serve to customers an efficient and comfort trike. Some innovative technologies
are used to increase rider’s experience and safety. The aim of design is to make a
better future hybrid Trike. The design is chosen to give dazzling experience to riders.
The design consideration gives a fully safe trike for riders and also to bystanders. Of
course, this trike is new for everyone but people will love it. It will become a status in
society.

1. Introduction
LUMINOUS is the team of Automobile Branch which participated in
SAEINDIA Efficycle Event of 2014. Team LUMINOUS worked on the new design
concept. As per concept of design LUMINOUS Trike gives attractive look and makes
marvelous any one. The design concept is fully dependent on Indian road condition,
which gives better experience to rider & fun on three wheels. This concept has sporty
look and also it can be ride by 2 riders with high stability and traction.
This concept use recumbent design with better comfort & stability. In India,
recumbent concept has lots of scope. Recumbent design gives many advantages than
upright bicycle. Recumbent seat reduces many health problems and useful in exercise
with low paddle force to rider.
We make vehicle concept in Tadpole design, which uses 2FW & 1RW concept with
‘Hybrid System’. Tadpole concept has many advantages which give rider full stability
and high braking force. Recumbent trikes are very well suited for long distance
touring since the comfortable rider position reduces strain to the riders’ body.
Concept of hybrid system uses Human power & Electric power alternately or
simultaneous, which also known as Eco-Friendly Concept. With use of human power
rider can charge battery and use it at any time as per rider’s requirement. With use of
electric drive, rider can easily drive their trike at gradient.
In this system GPS system, sensors, belt alarm system, app system, theft alarm
system, etc. can use. But in this concept we did not use these systems because of more
cost. But our team is able to use all new technologies or creativity as per customer
requirement with using modification in trike.
The arrangement of paddle system does with the scientific view to keep healthy the
rider. More details of advantage of tadpole, steering system, seating arrangement,
wheel base, wheel track, wheel size, suspension, drive systems, Hybrid system etc.
are given below with full specification.

2. SAEINDIA
SAEINDIA is an affiliate society of SAE International, registered as an Indian non-
profit engineering and scientific society dedicated to the advancement of mobility
community in India. As an individual member driven society of mobility practitioners,
SAEINDIA includes engineers, executives from industry, government officials,
academics and students. Principal emphasis is placed on transport industries such as
automotive, aerospace and commercial vehicles.
SAEINDIA was formed in India in 1994-95 with Dr. Pawan Goenka, appointed as
advisor for India. The SAE president held discussions with the Indian automotive
industry and as a result, the western Indian Section was established. This event
provides a real world engineering challenge for the SAEINDIA student member that
reflects the steps involved in the entire process from design and engineering to
production to marketing and endurance.
Student Competitions
SAEINDIA holds a variety of competitions every year for engineering students across
the country.
1. SUPRA SAEINDIA
2. BAJA SAEINDIA (eBAJA from 2014)
3. Effi Cycle
4. Aero Design
5. Eco Kart

3. Effi-Cycle
Efficycle is the event which organized by SAEINDIA. Efficycle is an intercollegiate
design competition for undergraduate and graduate engineering students where teams
have to design and fabricate an Energy Efficient Hybrid-Human Powered –three
wheeled-electric vehicle.
The purpose of this event is to provide an opportunity for engineering students by
setting up a trend of using eco-friendly vehicles in India and come up with some
innovative design. Main concept of this event is that the students have to tackle real
world engineering problems, work in multidisciplinary teams, practice design for
manufacturability and manage full product development cycle life.
Effi-Cycle gives lots of scope to the Engineering student while their study to think
creative, make creative and to drive the future. This concept also uses ‘Hybrid
System’, which is also useful in automotive industries. Due to global warming effect,
this green vehicle is very helpful to reduce the pollution on earth.

5. About Event
Virtual Round
SAEINDIA organizes the event of Efficycle every year. Every year around 200 teams
participated in the Efficycle Event. Every year number of team increases for virtual
round. But only limited teams are chosen through virtual round for main round.
In 2014, 225 teams participated in Event. But only 90 teams were selected for the
main round through the designing round. As per the distribution of zone, teams have
to face presentation round/virtual round/designing round on respected zone.
Presentation of design were given by 145 teams at KIET, Ghaziabad on 21st
-22nd
June
and remaining teams gave their presentation to RIT, Chennai on 28th
-29th
June.
Only 90 teams were selected for main round. The result was declared on 10th
