The
new
video
shows
the
F77
being
pushed
to
its
limits
as
the
Ultraviolette
team
monitor
the
progress
with
the
help
of
a
host
of
sensors
fitted
to
the
electric
motorcycle’s
test
mules.
The
testing
procedures
saw
the
electric
motorcycle’s
acceleration,
braking,
handling
and
stability
being
evaluated
on
the
airstrip.

The
tests
are
a
mix
of
qualitative
(rider
feedback
on
the
bike
while
being
ridden
in
different
conditions)
and
quantitative.
The
latter
compares
the
information
received
from
the
qualitative
tests
with
tangible
data
captured
by
the
sensors
including
pitch,
roll,
yaw,
and
stiffness
among
others.

The
test
mules
of
the
Ultraviolette
F77
were
put
through
the
wringer.
The
riders
pushed
them
through
slaloms,
accelerated
and
braked
hard
and
tested
the
wobble
and
weaving
characteristics
to
simulate
what
the
bikes
will
have
to
endure
in
the
real
world.

Backed
by
TVS
Motors,
Ultraviolette’s
F77
is
a
performance-oriented
electric
motorcycle.
Powered
by
a
25kW
motor
connected
to
a
4.2Kwh
pack
of
three
lithium-ion
batteries,
the
Ultraviolette
F77
claims
some
rather
potent
figures
for
a
bike
of
its
size.

The
powerplant
for
the
F77
produces
33.5bhp
at
2250rpm
along
with
450Nm
of
peak
torque
at
the
wheel.
This,
claims
Ultraviolette
is
enough
to
push
the
electric
F77
from
0-60km/h
in
just
2.9
seconds
and
hits
100km/h
in
7.5
seconds.
The
electric
motorcycle
has
a
claimed
top
speed
of
147km/h.
The
F77
weighs
in
at
158
kilogrammes.

The
battery
pack
supports
both
regular
and
fast
charging.
Plugged
into
a
regular
wall
socket,
the
F77
takes
five
hours
to
fully
charge
up.
However,
plug
it
into
a
fast
CCS
charger
and
the
bike’s
battery’s
fill
up
to
the
brim
in
just
one
and
a
half
hours.

To
take
care
of
the
rough
stuff,
the
Ultraviolette
F77
is
fitted
with
inverted
cartridge-style
front
forks
while
the
rear
end
features
a
gas-charged
mono-shock
with
preload
adjustability.

Braking
is
taken
care
of
by
a
320mm
drilled
disc
up
front
with
a
four-piston
fixed
calliper
while
the
rear
features
a
230mm
drilled
disc
with
a
single-piston
floating
calliper.
The
F77
features
a
dual-channel
anti-lock
braking
system
(ABS).
The
bike
sits
on
17-inch
rims
which
are
clad
with
a
110/70
R17
tyre
at
the
front
while
the
rear
tyre
is
a
150/60
R17
unit.

The
F77
includes
features
a
9-axis
Inertial
Measurement
Unit
(IMU)
for
Ride
Analytics
with
a
built-in
accelerometer,
gyroscope
and
magnetometer
along
with
GPS/GLONASS
positioning
for
real-time
speed
and
location
discovery
and
geofencing.

Other
features
include
customisable
riding
modes,
variable
regenerative
braking,
OTA
along
with
safety
features
like
a
side
stand
sensor
and
fall
&
crash
sensors
among
others.

Thoughts
on
the
Ultraviolette
F77
Undergoing
Performance
Testing

The
Ultraviolette
F77
is
one
of
the
most
anticipated
homegrown
electric
motorcycles
for
the
Indian
market.
Seeing
it
being
pushed
to
its
limits
before
its
launch,
shows
us
just
how
hard
the
team
at
Ultraviolette
are
working
to
make
the
F77
something
that
riders
will
learn
to
enjoy
to
the
max.
