SAFE OPERATION

Local Safety Regulations

• Your Serial 1 eBicycle conforms to all safety standards and regulations effective on the date of manufacture.
• Know and respect the rules of the road. It is your responsibility to comply with the laws and regulations of the areas where you ride. Read the safety information that is provided by your national, regional, or local traffic authority. Make sure all equipment required by law is installed and/or utilized and in good operating condition.
• In most countries, regulations for the use of an eBicycle are the same as those for a standard bicycle. However, there may be local differences such as where you can ride, minimum rider age, or required equipment and registration. It is the rider’s responsibility to know and obey local eBicycle regulations.

General Safety

WARNING

• eBicycles are different than bicycles. They operate and handle differently. Unskilled or improper use could result in loss of control, death, or serious injury.
• Always wear a helmet, appropriate to the type of riding you will be doing, when riding your eBicycle.
• Keep body parts and other objects away from the moving belt or chain, turning pedals and cranks, and spinning wheels of your eBicycle. It is possible that entrapment may occur during normal use or maintenance.
• Never tow a person or item (including a trailer) or allow the eBicycle to be towed.

Safe Operation
Before operating your new eBicycle, it is your responsibility to read and follow the operating and maintenance instructions in this manual and follow these rules for your personal safety.
WARNING

• Striking an object, such as a curb or pothole, can cause internal tire and/or rim damage. If an object is struck, have the tire and rim inspected immediately by a trained professional. A damaged wheel can fail while riding and adversely affect stability and handling, which could result in death or serious injury.
• Always pay strict attention to road surfaces and wind conditions and keep both hands on the handlebar grips when riding. Any two wheeled vehicle may be subject to upsetting forces such as wind blasts from passing vehicles, holes in the pavement, rough road surfaces, rider control error, etc. These forces may influence the handling characteristics of your eBicycle. If this happens, reduce speed and guide the eBicycle with a relaxed grip to a controlled condition. Do not brake abruptly or force the handlebar. This may aggravate an unstable condition.

Brake Safety

WARNING
Apply front and rear brakes evenly. Favoring one brake accelerates wear and reduces braking efficiency. Operation with excessively worn brakes can lead to brake failure, which could result in death or serious injury.

Battery Safety

WARNING

• This vehicle contains a rechargeable battery. An improperly handled or damaged battery can cause electrical shock and/or fire, which could result in death or serious injury.
• Do not disassemble, short-circuit, or use battery in any way other than its intended purpose.
• Do not connect to charger if battery is cracked or damaged due to impacts, falls, and other compromises to the integrity of the case or its contents.
• Do not immerse battery in fluids such as water or acid.
• Keep away from fire. Improper charging, impact, or exposure to fire can damage the battery.
• Use only the lithium-ion battery and charger specified by the manufacturer. Charge the battery within operating temperature range of 32° to 113° F [0° to 45° C]. Charge the battery before use if unused for more than one month.
• A damaged battery can leak electrolyte. Contact with electrolyte can cause serious chemical burns or blindness. If electrolyte comes in contact with eyes, skin, or clothing rinse affected area with clean water and seek medical attention immediately.

Wet Weather Riding

WARNING
When riding on wet roads, brake efficiency and traction are greatly reduced, resulting in increased braking distances. Failure to use care when braking, accelerating, or turning on wet roads can cause loss of control, which could result in death or serious injury. |
Rider Visibility
Riding an eBicycle at night or in other poor visibility conditions is more dangerous than riding during the day. A bicyclist can be difficult for motorists and pedestrians to see. If you are going to ride in those conditions, consult a qualified service provider about equipment that improves your ability to see and be seen by others. Find qualified service providers at www.Serial1.com.

FIT

Verify your eBicycle is the correct size. Correct fit is essential for a safe and pleasant ride.
Stand over Height
Stand over height is the basic element of eBicycle fit. It is the distance from the ground to the middle of the top tube.
Step-Over Frame
When straddling the top tube of a Step-Over style bike, you should have 1 – 2 in [2.5 – 5 cm] of clearance between yourself and the bike.
Step-Thru Frame
Stand over height does not apply to eBicycles with step-thru frames. Instead, the limiting dimension is determined by saddle height range.

Saddle Position

To get the most performance and comfort from your eBicycle, correct saddle adjustment is important. If the saddle position is not comfortable for you, adjust the saddle or seat post or see a qualified service provider.
The saddle can be adjusted in three directions:

• Up and down
• Front and back
• Saddle angle

Adjust your saddle position without exceeding the limits set by the height of the top of the seat tube and the “minimum insertion” or “maximum extension” mark on the seat post.

1. While standing next to your eBicycle, loosen the seat clamp with the multi-tool and raise your saddle to the height of your hip bone. Re-tighten the seat clamp with the torque tool to 6 Nm.
2. Sit on your bike and bring the pedals / crank arms perpendicular to the ground. Your leg should be locked straight and your knee fully locked. If it is not, get off the bike and slowly increase the height of the saddle, repeating as necessary until the correct position is attained.
   

Handlebar Height
The eBicycle is equipped with a “thread less” stem and is not height adjustable.~

The drive motor is connected to the rear wheel assembly with a carbon fiber- reinforced drive belt (similar to motorcycle drive belts). The drive belt provides smooth, quiet, and low-maintenance operation.

Continuously Variable Transmission

Your eBicycle may come equipped with an electronically controlled CVT (Continuously Variable Transmission) on the rear hub that delivers seamless gear changes and transmission of power at any speed. There is no shifting required; the transmission automatically adjusts the gear ratio as terrain or speed changes. The transmission is fully enclosed without any exposed components and requires no maintenance.

DISPLAY

• Every eBicycle includes a display attached to the left handlebar. The display directly controls the eBicycle when utilizing the battery powered components. It will not function without battery power but is not needed to use the eBicycle as a traditional bicycle under pedal power only.
• Ergonomically arranged thumb-and-forefinger controls on all models allow the rider to operate the displays without lifting a hand off of the handlebar.
• The Power button is located on the back side of the display. To turn the bike on or off, press and hold the Power button for at least 1 second before releasing.

“All round” Display

RUSH/CTY models utilize a Brose
“All round” display with a 1.5 in [37 mm] TFT screen. The screen can show at least the selected ride mode, current speed, odometer/trip meter, battery charge level, and headlamp on/off status.

“Remote” Display

MOSH/CTY models utilize a Brose
“Remote” display with an LED indicator. The LED indicator can show the selected ride mode, battery charge level, and headlamp on/off status.

RIDE MODES

Serial 1 eBicycles by default have 4 selectable Ride Modes, a Walk Assist, and an Off Mode. The current selectable ride mode will be indicated on the display (either screen or LED indicator).

Eco Mode

Best used in flat-and-favorable conditions when you want just a gentle amount of assistance without unnecessarily depleting the battery.

Tour Mode

Best used when you desire a consistent-but-still-transparent level of electric assistance, for the optimal blend of assistance and battery economy under mixed riding conditions.

Sport Mode

Best used when you want pronounced assistance away from corners or over rolling hills, or to ride further or faster than you would under your own power alone.

Boost Mode

Best used when confronting a steep hill, a strong headwind, or any other condition where you might require a sustained boost of substantial assistance.

Walk Assist

A push-button “walk-assist” function which provides a low level of forward motion to help easily maneuver the eBicycle at walking speeds, especially when there is a need to push the eBicycle up a hill

Off

Ride Modes can be turned to an Off position, which will provide no additional pedal assist. However, lighting and the display will still be active if the battery has charge.

LIGHTING

Your eBicycle features integrated lighting for safety and convenience.

• The LED front headtube badge lighting (“Signature Light”) and the rear taillamp are illuminated any time the eBicycle is turned on.
• A button on the display illuminates the LED headlamp.
• The rear brake lamp automatically illuminates upon deceleration.
