NOTICE: 1 . Pleasekeep the original packaging for at least 1 5 days !

2 . Before assembling your bike, it’ s recommended to remove the battery for the reasons outlined below:

• Determine if there’ s battery drain or damage during shipping.

• Reduce the weight of the ebike to make it easier to maneuver the bike while assembling

• Avoid battery damage during the assembly process

Recommended Torque Values

NOTICE: Using an impact driver to achieve the required torque is not recommended as it might cause damage We suggest you use the wrench set we provided and extra tools to manually adjust nuts and bolts.

Assembly Instructions

Handlebar Installation ( 4 mm Hex Wrench )

Step 1 : Loosen the bolts on your bike stem.

Step 2:

Step 3: Center your handlebars and rotate them to align to the marking pointed to in the below image. Tighten bolts to handlebar stem, but don’t tighten completely as you may want to further adjust the angle later to align more precisely. Test the positioning, and adjust the handlebar to your preferred angle. After determining the best position, completely tighten all the bolts on the stem.

NOTICE: In addition to angle, the height of the handlebar can be adjusted by adding or removing the headset sp acers if needed. For those without experience, we recommend having a professional make such adjustments for safety reasons.

WARNING: Overextending the seatpost can cause it to break or come off your bike, putting you at very high risk of serious injury or death. Avoid this danger by inserting your seatpost into the seat tube far enough that the minimum insertion point is no longer visible.

Adjust the Seat Angle:

Step 1:

Loosen the seat adjustment bolt beneath the seat. Move the seat backward or forward and tilt to adjust the angle within the limit markings etched on the seat rail. Do not exceed the limit markings, to ensure the safety of yourself and the bike.

Step 2:

Tighten the seat adjustment bolt. Ensure the top and bottom of the seat rail clamp are aligned, so that the seat adjustment bol t will clamp the seat rails together properly.

NOTICE: The seat angle has been preadjusted to factory safety standards. Please make note of original settings, and only adjust if nece ssary.

Lower pedal setings (u/2) are popular for Yotobike riders to use ofter work or when leisurely exercise is prefered. These are best to use on the way work,

to refresh yourself and relieve stress accumulated throughout the entire workday. Moreover, lower settings can extend usable range for longer rides, maximizing enjoyment while minimizing physical stress and fatigue.

Throttle-only

The throttle mode is similar to how a motorcycle or scooter operates, alleviating the need to pedal or providing an additionalboost simply by twisting the throttle.

I n this mode, the Yotobikewill perform like a normal bike, as you’ll be riding without any assistance from the motor. This mode is especially useful if you run out of battery, or are looking for more intensive resistance training.

We suggest that you select a lower assistance level when you first ride your Yotobike. After becoming more comfortable witthe riding characteristics of our e-bike,

and more familiar with the varvino range recuirements of vour most common destinations and commuting routes, you can then make any needed adjustments to pedal assist settings, as well as throttle use frequency, riding position, etc.

Riding Limitations

F ollowing are some limitations needing riders’ careful attention to ensure the mid motor does not overheat or become damaged from excessive loading:

• Do not attempt to ride up hills steeper than 15 % grade.

• Use the pedals to assist the motor when climbing hills and accelerating from a stop.

• Avoid sudden starts and stops.

• G enerally accelerate at a moderate pace, rather than aggressively.

Parking & Transport

Follow these basic parking, storage, and transport tips to ensure your bike is well cared for , both on and off the road:

• W hen walking with the bike, turn off the power to avoid accidental acceleration.

•

•

Though our bikes are water resistant (PX4 Water Resistance), please do not park your bike outdoors in cold or inclement weather for extended periods. hen parking, switch the power and any lights off to conserve battery, remove the key from the bike, and ensure the battery is secured and locked to the frame.

• In public places, help keep your Yotobike safe and secure from theft by always locking it up.

• Make sure to not park, store or transport your Yotobike on a rack that is not designed for the size and weight of the bike. W hen storing or carrying your bike on a rack for transport, remove the battery to reduce the weight and make li fting or loading easier.

Carrying Loads&Leopard

Total Payload Capacity of Leopard W eight: 7 0 lbs

Cargo Safe Operation Tips:

The following list provides important tips for the safe operation of the Leopard when used for carrying cargo:

1 . Make sure to load the cargo as low as possible to lower the center of gravity and improve stability.

2 . Ensure your loads are properly secured and periodically check that nothing has loosened.

3 . Plan your route accordingly when cargo is loaded on the Leopard, considering hill climbing ability , steering, and braking . Also account for

moderately reduced range when carrying extra cargo weight (or an additional passenger).

4 Try to get a feel for the cargo load in a flat and open private area before riding on public roads.

5. loss

Make sure to not use the front brake by itself, with or without cargo. Always apply the rear brake first followed by the front of control is possible when the front brake is operated independently, especially at higher speeds.

6 The kickstand is not designed to hold the bike upright with cargo by itself, always manually hold the bike upright when loading or carrying cargo

Safety and Care Instructions

To clean the e- bike, wipe the frame with a damp cloth soaked in a mild, non- abrasive, non- corrosive detergent mixture. Wipe or spray all unpainted parts with anti- rust treatment after being used in coastal areas or areas with salty air or water

Never immerse the bike or any components in water, as the electrical system may be damaged . If the hub and bottom brack et bear ingshave been

submerged in water, they should be removed and re-greased (this will prevent accelerated bearing deterioration). eriodically check wiring and connectors to ensure there is no damage, and the connections are secure. Store under shelter, avoiding extended exposure to cold or inclement weather If exposed to rain or excess moisture, dry your b icycle afterward and apply anti- rust treatment to the chain and any other unpainted steel surfaces.

Battery Maintenance ( 48V 20Ah Battery with Samsung Cells )

Don't fully drain your battery. Turn off the power when the battery charge is low.

Fully charge the battery after each use, no matter how much power is used. This will prolong the battery life. If the battery i s not used for a long time, store the battery with a full charge and charge it once a month.

The Leopard can be safely ridden in light rain. However,riding through very heavy downpours or through flooded streets is not recommended, as the

crank and/or motor can get wet, which may cause problems.

Keep the battery away from open flame or a high-temperature heat source. Do not expose the battery to direct sunlight or recharge immediately after

use in high-temperature weather.

We recommend cleaning the chain after each ride, especially in rainy and humid environments. Use a dry cloth to wipe the chain and its accessories clean. Use a brush to remove sand and dirt stuck in the chain, along with use warm soapy water if needed. Do not use strong aci dic or alkaline cleaning

Apply lubricating oil after cleaning to avoid rust. First, make sure the chain is dry, and then apply the lubricating oil into

the bearings.

To prevent unnecessary chain wear, try to maintain a vertical chain position when shifting gears (do not use the smallest gear with the smalest flywheel, or the largest gear with the largest flywheel, etc.)

Always use a clean, oi-free lint-free cloth with plain or soapy water to clean your bike.To prevent water from ftowing into the front fork, you can turn the bike upside down.
