4.4 Ride modes On the knob to the left, you can put the bike into 3 different
riding modes. Never ride the bike above your comfort level and always ride
according to your personal riding skills. We always recommend a new CAKE-rider
to start on the first mode to get used to the bike and the differences between
an electric motor and an Internal combustion engine. The 3 different ride
modes have different attributes in terms of top speed, acceleration, and
torque to suit riders of all riding levels, from beginners to professionals.
Ride mode 1 – Explore The ultimate mode for exploration. Speed limited to
60km/h (28mph) and up to 3 hours trail riding. This mode is ALWAYS recommended
when riding a CAKE bike for the first time. This power mode still has high
torque for rideability offroad as well as something for new riders to progress
with. This Mode is perfect for tracks where control is more valued than power.
Ride mode 2 – Excite Perfect for enduro, track or active trail riding. Offers
up to 1,5h riding time. Top speed 90km/h.
Ride mode 3 – Elevate Overclocked, an invitation to infinity and beyond. Enter
Elevate cautiously and be aware that this is not a commercially designed mode
and riding time will be reduced. Top speed 90km/h. To not damage the battery
power and torque will be limited as the battery heats up. If the battery
overheats frequently the battery life time will be reduced.
NOTICE All ride modes and brake modes are configurable in the Ride CAKE app.
You can always reset ride mode to factory setting in the app
24
4.5 Brake modes On the knob to the right, you can put the bike into 3
different braking modes. This ranges from a freewheel experience, much of what
you feel on an MTB, which is suited for mellow riding on flats, to a hard
engine brake, that is similar to the engine brake on a 4-stroke motorcycle,
which is suited for technical riding. All the energy from the braking goes
back into the battery for extended range.
Brake mode 1 Freewheel, no motor brake. Gives the same sensation as riding a
bike, perfect for mellow riding and the ultimate freedom experience.
Brake mode 2 Intermediate motor brake with energy regeneration. As you release
the throttle you feel the bike slowing down at a slow pace. This can boost
your confidence when riding a bit more technical terrain as you get better
control over the bike. The braking power is regenerated to the battery for
extra range.
Brake mode 3 Hard motor brake with energy regeneration. When releasing the
throttle, the bike will slow down significantly. This could be uncomfortable
for novice riders as the braking is quite hard. This brake mode is best suited
for technical tracks where full control for the bike is needed. All the
braking power is regenerated back to charge the battery for extended range.
WARNING! Risk of personal injury. When slowing down using the motor brake,
other road users are not notified of your slowing down. Use the motor brake
with caution. Always use the mechanical brakes to bring the vehicle to a
standstill.

and property damage.
5.3 Starting Before you start the vehicle, please remember that this is an
all-electric vehicle that is very silent when it’s on. 1. Plug the battery
cable into the battery. 2. Plug in the kill switch, in Fig. 12. The kill
switch is located on the right side
of the handlebar. When the kill switch is connected with the magnet, the bike
is turned on. When you are done riding or in case of an emergency, pull the
kill switch to turn off the bike. ALWAYS wear the kill switch strap around
your wrist when riding. This is to prevent further damage to the rider, the
vehicle or other property. When falling, losing control or feeling unsafe,
release your right hand from the handlebar and pull it back, this will
disconnect the kill switch and turn the bike off. ALWAYS disconnect the kill
switch when not riding. As the bike makes no noise when on standby mode, it’s
impossible for bystanders to know if the bike is on or not. This can cause
accidents if people are pulling the throttle while expecting a turned off
bike.
