IEEE Electrification - March 2022 - 74

The lean start-up methodology was successfully
implemented. It managed to speed up the engineering
design, prototyping, and testing time of the electric
motorcycle. The total cycle time for those activities
was less than two years. Moreover, the electric scooter
has been mass produced and sold in Indonesia under
the brand name of GESITS. It is real evidence of the
successful implementation of the proposed framework
methodology.

employed to perform the two-level testing. The testing
results are presented in Figure 8 as follows.
Based on the dynamometer testing results, it can be
concluded that the electric motorcycle performance is
as expected during engineering design and simulation.
The maximum power generated by the axial BLDC
motor was 4.5 hp (3.3 kW). Its maximum torque was
roughly 34.3 NM. This maximum available torque is
slightly higher than its requirement, which was only
28 NM. Hence, its fixed gear ratio should be adjusted
so that the motor-available torque can be reduced to
28 NM. A 1:6 gear ratio is used instead of 1:5 as per the
initial design.
Road Testing
Once the laboratory test is finished and the electric
motorcycle performance deemed to be as expected, the
next step was to test the prototype in real life (on road
conditions). This test validated the engineering design
and analyzed whether the MVP was ready from the
designing phase. The total distance of the test was
1,500 km from Jakarta to Denpasar, a journey of five
days. Testing 10 MVPs showed that only minor revisions
were needed to improve the aesthetics of the electric
scooter, although the performance was as expected.
Therefore, the development process ended, and the
next phase finalized the electric scooter design. The
results were blueprints, quantities, and bill of materials
of the electric scooter. Based on the design's minor revision,
the mass-production version of the electric scooter
can be seen in Figure 9.
Conclusions
An innovation-based concept was successfully used to
develop the first Indonesia electric scooter in less than
two years. This was a breakthrough and proof that
the proposed innovation-based framework worked successfully
to achieve the goal. Moreover, the scooter's performance
was as expected.
