2. General information
2.1 Safety advice
Riding
When riding a CAKE bike for the first time, there are a few things to consider.
The bike has an electric motor with instant torque and a primary drive with
no gears or clutch, which means you have all the power available at all times
in the throttle. It’s very sensitive and it’s highly recommended to start riding
in the 1st riding mode to get used to riding the Kalk&.
• Never ride the bike under the influence of alcohol or drugs
• Always respect local laws and regulations when riding

2.2 Controls and Power modes
Rider controls and components
Grips, Throttle, Kill switch, Front brake, Stem, Display, Handlebar control
State Of Charge Indicator
The application includes a Battery SOC estimator, which uses an algorithm to
estimate the SOC of the battery. The SOC is indicated on the top right of the
display
Kill switch
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 o the bike.

WARNING: Read and understand this manual and its safety instructions
before using this product. Failure to do so can result in serious injury or death.
The product shall only be used as described by the manufacturer. Any other
use is considered unprofessional and dangerous.

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 o.
ALWAYS disconnect the kill switch when not riding. As the bike is electric,
it’s hard 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 o bike.
Brakes
As the Kalk& bike is built for o-road use, it does not have ABS brakes to give
the rider full control over the bike when riding in o-road conditions. Please
be cautious not to lock the wheels when braking in trac. The front brake is
located on the right side on the handlebar, and the rear brake is located by
the right foot peg and is operated by the right foot.
Display
The display on the stem is the bike’s control panel. Here, you will be able
to see the speedometer, odometer, trip meter, power mode, brake mode,
service intervals, warning signals and limiters and error codes.
Operating the display
When the bike has been turned on, press the upper, white display button to
activate the bike.
Changing Power mode
When the bike has been activated, press the middle button on the display
to change power mode. You will always change the power mode, starting
from “Mode 1” to “Mode 2” to “Mode 3” to ”Mode C” and back to “Mode 1”
again, one press at a time. The bike will make a dierent sound depending
on the selected power mode.
Note: If you don’t have power mode C in the display, but do have a
connectivity module, you need to create an account in the app and configure
the custom power mode.

Changing Brake mode
When the bike has been activated, press the lower button on the display to
change brake mode. You will always change the brake mode, starting from
“Mode 1” to “Mode 2” to “Mode 3” to “Mode C” and back to “Mode 1” again,
one press at a time. The bike will make a dierent sound depending on the
selected brake mode.
Note: If you don’t have brake mode C in the display, but do have a connectivity
module, you need to create an account in the app and configure the custom
brake mode.
WARNING: When riding in trac and utilizing the brake mode, the braking
light will not be activated and alarm other in trac that you are slowing down.
Use with caution and always use the real brakes as a mean to stop your bike
when riding.
Change between Miles per hour and Kilometers per hour
When the bike has been activated. Press and hold the lower button on the
display in order to change between mph and km/h.
Change between odometer and trip meter
When the bike has been activated, press and hold the upper white button on

See information about the software and bike information
When you are starting the bike and the display is loading, when you get to
the screen ”Press to start”, press and hold the button on the right side of your
display to access this information. This can be useful during service and ma-
intenance.

Brake modes
The bike has 4 dierent brake modes (1,2,3 & C). 3 pre-configured modes
ranging from a freewheel experience that keeps you rolling after you release
the throttle, to a harder motor brake that gently slows you down as you
release the throttle. 1 custom brake mode that you can adjust according to
your driving behavior.
Note: If you don’t have brake mode C in the display, but do have a connectivity
module, you need to create an account in the app and configure the custom
brake mode.
Brake mode 1
No motor braking. Gives the same sensation as riding a bike, perfect for mel-
low riding and the ultimate freedom experience.
Brake mode 2
Moderate motor braking. 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 breaking. When releasing the throttle, the bike will slow down sig-
nificantly. 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 of
the bike is needed. All the braking power is regenerated back to charge the
battery for extended range.
Brake mode C
A configurable brake mode. Adjust according to your driving behavior. To con-
figure brake mode C you need to create an account in the app and configure
the custom brake mode.
Note: If you don’t have brake mode C in the display, but do have a connectivity
module, you need to create an account in the app and configure the custom
brake mode.

Power mode
There are 4 dierent power modes to choose from when riding the bike (1,2,3
& C). 3 pre-configured power modes with dierent attributes in terms of top
speed, acceleration, and torque to suit riders of all riding levels, from begin-
ners to professionals. 1 custom power mode that you can adjust according
to your driving behavior. 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 with the first mode to get used to the bike and the
dierences between an electric motor and an internal combustion engine.
Note: If you don’t have power mode C in the display, but do have a connectivi-
ty module, you need to create an account in the app and configure the custom
power mode.
Power mode 1
This mode is ALWAYS recommended when riding a CAKE bike for the first
time. It has a limited top speed of 45 km/h (28 mph) and soft acceleration.
This Power mode still has a high torque for rideability o-road as well as so-
mething for new riders to progress with. This mode is perfect for tracks where
control is more valued than power.
Power mode 2
With a top speed of 70 km/h (43 mph) and a good acceleration, this mode is
perfect for enduro riding out in the woods.
Power mode 3
With no restrictions when it comes to the performance, this mode is perfect
when you need all the power available. This mode is recommended for highly
skilled riders only.
Power mode C
A configurable power mode. Adjust according to your driving behavior. To con-
figure power mode C you need to create an account in the app and configure
the custom power mode.
Note: If you don’t have the Power mode C in the display you need to create an
account in the app and configure the custom power mode.

Charging screen
As a safety measure, you are not able to ride your bike while charging the
bike. The screen will display the loading screen when charging the bike. Un-
plug the charger to use the display.
Limited performance
The bike has a level of self-preservation, which means that during certain con-
ditions, the performance will be limited or even stopped completely. During
the following conditions, the performance will be limited.
Batter Overvoltage or Battery Undervoltage
If the voltage is out of the ordinary range of the battery pack, such as an
overcharged battery pack or an empty battery pack, the performance will be
limited as to not damage the battery or other components in the drivetrain.
Note: This occurs naturally when you turn o the bike and it is not an issue.
Battery overtemperature and Battery undertemperature
If the battery pack is too warm or too cold the performance is limited as it
could otherwise cause damage and decrease the life cycles of the battery
pack. The limiter is proportional to the temperature and will stop the bike
completely if it’s too hot or cold.
Note: In order to avoid potential limiters when out riding. It’s recommended
to keep your bike inside if the outside temperature isn’t within the following
range: +2° C to +35° C (36 F to 95 F).
Controller overtemperature
If the controller is getting too hot, the performance will gradually be limited.
Go easy on the throttle or take a short break if this occurs.
Motor overtemperature
If the motor is getting too hot, the performance will gradually be limited.
Go easy on the throttle or take a short break if this occurs.

Error codes
If a critical electrical error occurs, the display will show a message with a code
on the screen. In the unlikely event that this happens, please take a picture
of the code with your phone or write the code down and contact CAKE at
[e-mail]

3. Regular inspection and Maintenance
3.1 Before each ride
To make sure that your bike is always in good condition and avoid injury or
damage, please make sure to always take care of your CAKE Kalk& bike by the
following steps.
• Check the angle of your mirrors.
• Try your turn signals, head light, rear light, braking light and horn.
• Check the wheels(see 3.3 Wheels and tires).
• Check the condition and tension of the chain.
• Clean your bike (see Chapter 5.2 - Cleaning).
• Check the suspension.
• Check that the headset is properly tightened.
• Check that the brakes are functioning properly by doing a brake test.

3.3 Wheels and Tires
The wheels should be inflated to a pressure of Should be: 200 kPa / 29 psi / 2 bar
With factory new wheels, you have to check and tighten the spokes after
riding. To make sure the wheels are in their best shape you need to tighten
the spokes after your first rides, up to a couple of hours. You will find some
loose spokes for sure, this is because the spokes and rim will work a bit when
they are new. Be sure that when you start to tighten your spokes the hub is
completely cooled down, because the braking hubs get warm.
Tighten your spokes as follow. Use a spoke wrench and tighten the nipple
which is found where the spoke and rim meets. Check all spokes with your
spoke wrench and tighten loose spokes. Don’t tighten loose spokes too firm
otherwise you will pull the wheel out of his straight position. Spokes that are
still tightened don’t need to be tightened extra firm. Keep repeating to check
the spokes after your second and third ride. You will find that the spokes keep
nicely tightened because they are now ”settled” in the hub and rim.

Now your CAKE wheels are ready to race. Keep checking your spokes regular-
ly. By checking regularly, we don’t mean that the spokes have to be tightened
every time. You just need to make sure that there are no loose spokes in the
wheel. If you tighten the spokes every time you check them the result can
be that after a while the spokes are all way too tight. Keep in mind: A spoke
needs to have the possibility to “stretch” with big impacts. When the spokes
are over tightened the spoke cannot stretch and it can break.
• Check that the tires are inflated with the correct pressure.
• Check the tires tread pattern is at least 3 mm deep.
• Check for bent spokes.
• Check that all spokes have the correct tension.
• Check that the brake discs are straight.
• Check that the axle of the front wheel is tightened correctly.
• Check that the rear axle is tightened correctly.
• Check that the axle of the rear wheel is adjusted correctly and evenly on
both sides, according to the swing arm markings.
3.4 Handlebar and Cockpit
Headset
Make sure that the headset bolt is tightened firmly and that there is no play
between the head tube and triple clamps when suspending the forks.

A
Adjusting the handlebar angle
See the instruction video on ridecake.com/en/makka-manuals-and-videos/ .
Tool: Allen key 5 mm.
1. Loosen the 4 stem bolts.
2. Adjust the handlebar angle and center the handlebar. Make use of the
handlebar guidelines.
3. Tighten the 4 stem bolts to 10 Nm.
4. Ensure to tighten the upper and lower bolts equally. Check that the gap
(A) between the upper and lower stem is equal. See Fig 1.
3.5 Suspension
Read the Öhlins manual at www.ridecake.com/manuals to change the
factory settings for your bodyweight and riding style. If the bike is not used
for longer periods of time, the fork might start leaking oil. This is due to the
rubber gaskets drying up. It’s therefore recommended not to let your bike
stand idle for too long periods at a time. Make sure that the linkage has no
damage. Make sure that all bolts on the linkage is firmly tightened.
3.6 Drivetrain and Chain
Chain
Check that the chain is in good condition. It’s advised to clean your chain and
applying chain lubricant when needed in order to prolong the lifetime of your
chain. Check that the chain has correct tension. The chain gets longer as the
bike is being used and will needed to be tensioned with time. It should have
