SAFETY & WARNINGS

Electric Assisted Bike Regulations
The EN 15194 EU standard or EPAC (Electric Power Assisted Cycle) conforms to the following characteristics for electric power assisted bikes:

• Motor assistance only starts when the cyclist pedals.
• The assistance cuts out as soon as the cyclist stops pedalling.
• The assistance cuts out as soon as the speed exceeds 25km/h.

Adherence to this standard enables the use of the electric bikes in the same conditions as any other bicycle, particularly on bicycle paths and bicycle- specific lanes.

Recommendation before First Ride

• Before first use, double-check the function of all the parts of your electric bike. If you have any doubts or if you detect a problem, contact Kogan.com for further support assistance.

• If you lend your bicycle to a third party, give them this user guide with the bicycle and ensure that they read it before the first ride.

• Respect local, state and national road traffic regulations.

• For your safety, it is highly recommended that you wear a certified helmet. Ensure you are always following local helmet laws while operating the bicycle.

• When used during heavy rain, snow, in slippery conditions or in the case of low visibility, be careful and adjust your speed.

• At night, ensure the bicycle headlights are activated while operating.

• Trying to repair anything that implies removing technical or electrical components is strongly advised against. If maintenance or repair is necessary, contact Kogan.com for support assistance.

• The manufacturer declines any responsibility due to overloading or items that are not correctly attached to the baggage rack.

• Using high pressured water jets to clean the bike is strongly advised against.

• Check the battery level before each use. Ensure the battery is fully charged prior to first use.

• In order to extend battery performance and lifespan, do not commence operation when the battery is only half-charged.

• The battery life will vary depending on where you ride it (inclines will reduce power rapidly) and how you ride (assistance mode chosen). The greater the assistance used, the more you’ll use the battery and the shorter it will last. This bike is fitted with gears; remember to use them accordingly relative to riding conditions in order to extend battery life. The amount of weight carried will also have an impact on battery lifespan.
  Extreme low temperatures can also impact battery lifespan.

• It is recommended that you charge the battery at least every 2 months when the bike is not used; during winter, for example.

• Store the battery in a dry place after having completely recharged it. Avoid extreme temperatures (both low and high) as they can damage the battery. Optimal operating range: -10°C to 35°C.

Cleaning and Maintenance

• Use a damp cloth with neutral detergent to clean the bike frame. Do not use any detergents or cleaning liquids liable to deteriorate the frame or components.
• Use a dedicated bicycle cleaner or hot soapy water to clean your bike and its components, such as wheels, hubs, rims, brakes and pedals. Rinse well with clean water before use.
• Do not use high pressure water jets to clean your bike, especially on the electrical components (such as the battery), as this may result in short circuiting or system malfunctions.
• All the components and parts of your bicycle are subject to normal wear and fatigue.
• Keep a close eye on any change in the shape or colour of a component or traces of oxidation (rust) on your bicycle. If this occurs, do not use the product until the component has been replaced.

Warning

• Do not ride after consuming alcohol or drugs (prescribed or not), or while under the affects of medication which might make you drowsy.
• Do not ride while you feel unwell, nor after consuming alcohol or drugs. This product has the potential to endanger yourself and others if not operated responsibly.
• Pedal-assisted bicycles are not designed for 2 or more people. Do not ride carry passengers as these bicycles are not designed to carry the additional load of a second rider.
• Do not put batteries in normal waste bins. Dispose of used batteries in a certified recycling facility.
• Do not over-lubricate; if oil contacts the wheel rim, brake pads or brake disks, this will result in loss of braking performance and an increase in stopping distances. This could potentially cause loss of control, accidents, and injury.

Transport
It is highly recommended that you do not overload your pedal-assisted bicycle, as this may damage the electrical components or cause malfunctions, such as overheating of the battery or the motor. Do not store the battery in excessively hot or cold places.

• Maximum transport weight on the bicycle must not exceed 90kg.
• Regularly check battery brackets and mountings.
• Always wear a helmet when riding your pedal-assisted bicycle.
• If a rack is not already fitted to your bicycle, please do not attempt to fit one yourself.
• Do not carry anything on the rack that might hide lights or reflectors.

OVERVIEW

Tools Supplied

Multifunction Wrench| 6mm Allen & Phillips Head Key| 3mm, 4mm & 5mm Allen Key (x3)
---|---|---

ASSEMBLY

Stem Assembly
Stem fitted in the head tube with an expanding bolt (Figure 1). Insert the stem into the head tube, respecting the minimum insertion limit as indicated on the stem and tighten the expanding bolt to 18Nm.
Before tightening the stem, make sure that it is in-line with the front wheel.

WARNING: To prevent steering system damage and possible loss of control, the stem must be inserted enough so that the minimum insertion marks are completely covered.
Handlebar Assembly
Position the handlebar inside the stem (Figure 2). Respecting assembly indications on the handlebar, tighten screw to 18Nm. Before completely tightening, check that the handlebar, the brake levers and shifter are correctly positioned.

Wheel Mounting

1. Place the wheel in a central position between the frame dropouts and the fork.

2. Install the quick release lever and ensure each side has a spring.

3. Tighten the adjusting nut.

4. Close the quick-release system. In order to prevent it coming loose, it is necessary to turn the adjusting nut such that the closing force of the release lever is at least 12 daN (about 12 Kg).
   Note: The quick-release lever should require a moderate amount of force to close but not to point where it is extremely difficult to close it.

5. To increase the closing force: turn the adjusting nut clockwise. Turn anticlockwise to reduce the force).

Seat Assembly
Insert the seat stem into the frame (Figure 4), you can use grease to help assembly. Insert at least to the minimal indication on the seat stem using rotary movements. Pull the quickrelease lever free and insert the seat-post to the minimal insertion marker indicated on the seat-post.
Tighten the quick-release clamp and then fold the lever to closed position.
Minimal torque specifications are 19.5Nm.

Brake Adjustment
Note: When the front wheel is installed properly, the disc brake rotor should be centered between the brake pads, recheck the disc brake is installed well in the following steps. DO NOT pull on the lever before the wheel is installed. It may cause the brake pads to bind together making it is difficult to separate them without the proper tools and expertise.

1. With the front wheel installed, the disc brake rotor should be centered between the brake pads, and securely fastened to the wheel. Use a 4, 5, or 6mm Allen Key to check the rotor mounting bolts to ensure that none of the bolts are loose.
2. Ensure that the mounting bolts on the disc brake are evenly tightened. If not, the disc brakes will be out of alignment with the rotor and you will not be able to brake efficiently or safely.
3. Adjust the brake: Loosen the pad adjustment screw (Y) by turning it counter clockwise one or two clicks. This operation creates appropriate clearance between the brake pad (X) and disc brake rotor on the inboard side. Check that both clearances between the disc brake rotor (Z) and brake pads are equal: inboard side = outboard side (Figure 5).
4. To test the function of the front brake, lift the front of the bike and spin the wheel.
   The wheel should not rub on the brake pads. Next, squeeze the brake lever and take note of the brake pads contacting the brake rotor. The pads should contact the rotor on both sides at the same time. Finally, hold the brake lever firm and try to move the bike forward. The brake should hold well enough to keep the wheel from moving.
   Repeat these steps for the rear wheel.

Installing Front Fender & Light

1. Install the preassembled fender to fork legs facing forward with fender bracket positioned behind the fork (Figure 6).

2. Slide a washer onto the mounting bolt and insert through fork and fender bracket.
   Place the other washer and front light onto the mounting bolt and secure the mounting nut as shown (Figure 7).

3. Attach fender arms (align the fender arm holes with the mounting holes on the fork end) then insert the mounting bolts through the fender arm holes to secure the bolts into the fork holes.

4. Attach the front wheel with retaining washer in place and tighten the axle nuts securely.
