Battery level check Your main battery state of charge is available for your convenience in the app.
Adjust ride modes Your bike supports different ride modes to tune the riding experience to your preference.
These ride modes are tuned to allow for maximum reach, maximum efficiency or maximum power when the bike is delivered.
In the app you can change the tuning of all ridemodes to whatever suits your riding style.
17

Advanced ride modes
NOTE: The following applies to bikes equipped with the feature `Advanced ride modes’. Advance ride modes let you go deeper into your bike settings to customize the riding experience even further.
· Adjust throttle sensitivity to allow for more aggressive response perfect for MX-style riding or gentler response that fits a muddy trail on rainy forest
· Adjust your throttle response delay to make you feel every little input on the throttle instantly be delivered to your back wheel or use a more forgiving setting for a smoother experience
· Adjust the traction control to optimize the power delivery to fit dry or slippery surfaces
Track rides When your bike is unlocked you can choose to track your ride using the record button on the main page. This will save your ride data in your app.
Troubleshooting If you experience a problem with your bike or detect an error code in your display you can use the diagnostic section in your app, found in the bottom of the home screen, to see detailed information of the reported error.
Bike movement, vehicle location/GPS Your bike is equipped with satellite location tracking. The location is reported via cellular connection and forwarded to your app. The tracking unit has a backup battery installed that will ensure location is collected and reported even if you remove the main battery.
Keep in mind that this backup battery is limited and to ensure continued operation of the tracking functionality please connect the main battery once a week and keep it connected for at least an hour (for example during a ride).
NOTE: Satellite tracking requires a clear view of the sky and that the bike cannot report an accurate location if the bike is parked in an underground garage for example.
The app will always tell you when your location shown in the app was collected.
18

NOTE: The app has two separate settings for the app and the bike, it is possible to separate settings for the bike and the app.

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.
