GENERAL INFO
Assembly and Fit
Correct assembly and fit are essential elements to ensure your bicycling
safety, performance, and comfort. Even if you have the experience, skill, and
tools to complete these essential steps before your first ride, Aventon
recommends having a certified, reputable bike mechanic to check your work.
NOTICE: If you do not have the experience, skill, and tools to complete
assembly and fit, Aventon highly recommends having a certified, reputable bike
mechanic complete these procedures as well as any future adjustments or
tuning.
NOTICE: A critical aspect of assembling your bike is securing the front wheel
and checking the tightness of the rear wheel axle nuts. Aventon bikes use
bolted on, through axle or quick release front wheel mounting mechanism and
the rear wheel is bolted on. These mechanisms may become loose or unsecured
during shipment or over time. The torque and security of all wheel mounting
hardware should be inspected upon arrival and on a regular basis. Both wheels
need to be properly secured before operating your bike.
Mandatory Equipment and Use Locations
Before riding, ensure you have all required and recommended safety equipment
and are following all laws pertaining to use an electric bike in your region.
For example, these laws may specify the need for mandatory equipment, use of
hand signals, and where you can ride.
Changing Components or Attaching Accessories
The use of non-original components or spare parts can jeopardize the safety of
your ebike, void your warranty and, in some cases, cause your ebike to not
conform with laws pertaining to your bike.
Note: The replacement of original components or installation of third- party accessories or accessories not from Aventon explicitly recommended for your bike model is at your own risk. Using aftermarket accessories or components that have not been tested by Aventon for safety and compatibility may void your warranty, create an unsafe riding condition, damage to property or your bike by Aventon, or result in serious injury or death.
Safety Check Before Each Ride
Always check the condition of your bike before you ride in addition to having
regular maintenance performed. If you are unsure of how to conduct a complete
check of the condition of your bike before every ride, you should consult a
certified, reputable bike mechanic for assistance.
Electrical System (Applicable to Pace, Sinch, Level, Soltera, Aventure)
and user preferences. It is critical that you familiarize yourself with all
aspects of your ebike ’s electrical system and check to see if it is working
correctly before every ride. The front and rear brake levers contain safety
power cutoff sWitcheS, which disables the hub motor’s assIstance when applied,
and both levers should be checked for correct operation. The throttle should
provide smooth acceleration when gradually applied. f the throttle, brake
lever cutoff switches, pedal assistance, or lighting are functioning
abnormally, intermittently, or not working, please discontinue the use of your
ebike immediately and contact the Aventon Support team for assistance.
Brakes
Ensure that the brakes and their system components are free from damage,
properly secured, and working correctly. When fully squeezed, both front and
rear brake levers should not be touching the handlebar. Take your bike to a
certified, reputable bike mechanic to have the brakes repaired if you find a
problem.
Tires and Wheels
Your wheels should always spin straight and must be repaired or replaced if
they wobble side to side or up and down when spinning. If your wheels become
untrue or spokes loosen, which can happen with normal use, we recommend that a
certified, reputable bike mechanic performs all-wheel tuning and truing
operations on your bike from Aventon. DO NOT attempt to true wheels or tighten
spokes unless you have adequate knowledge, tools, and experience. Ensure the
tires and inner tubes are in good working condition without any visual damage
and have the correct amount of air pressure. Always replace tires and inner
tubes with punctures, cuts, or damage before you ride. Tires without the
correct amount of air pressure can reduce performance, increase tire and
component wear, and make riding your bike unsafe.
Accessories, Straps, and Hardware
Ensure all hardware is secured and all approved accessories are properly
attached per the specific component manufacturer s instructions. It is good
practice to look over all hardware, straps, and accessories before each ride
and if you do discover something wrong or something that you are not sure
about, have it checked by a certified, reputable bike mechanic.
Suspension, Handlebar, Grips, and Seat Adjustments
before use. The suspension fork should be properly adjusted according to your
weight and terrain. Ensure the handlebar and handlebar stem are properly
aligned, fitted to the user, and secured to their recommend-ed torque values.
Handlebar grips should not move easily on the handlebar end. Loose, worn, or
damaged handlebar grips should be replaced before you ride . The seat and
seatpost should be properly aligned, fitted to the user, and the seatpost quick
release should be properly tightened, fully closed, and secured before riding.
Battery Charged, Secured, and Unplugged
Ensure the battery is adequately charged and operating properly. Ensure the
battery charger is unplugged from the outlet, battery, then stored in a safe
location before you ride. The battery MUST be locked onto the frame battery
mount properly before use. DO NOT operate the electrical system if the battery
is removed.

Park indoors when possible. If you must park outdoors in rain or wet conditions, leave your ebike outside for only a few hours and then park it in a dry location as soon as possible to allow all of the
systems to dry out. As with a regular bike, an ebike used in wet conditions needs more frequent maintenance to prevent rust, corrosion, etc. and to ensure all systems are working safely. -
In public places, your bike from Aventon Bikes must be parked in accordance with local rules and regulations.
-
Locking up your bike is recommended to ensure your bike is secure and the chance of theft is reduced.
-
Aventon Bikes makes no claims or recommendations on the proper lock hardware or procedures to secure your bike, but we do recommend you take appropriate precautions to keep your bike safe from theft.
-
Do not park, store, or transport your bike from Aventon Bikes on a vehicle rack not designed for the bike’s size and weight.
-
Use a vehicle rack compatible with the width of tires used on your bike. Some racks may not accommodate all tire widths.
-
When carrying your bike on a vehicle rack for transport, unlock and remove the battery. This will reduce the weight of the bike, make lifting and loading easier, and allow you to protect the battery by transporting it in the cab of a vehicle.
-
Avoid transporting bikes from Aventon Bikes on a vehicle rack during rain, as this may cause water damage to the electrical components.

(80-160 km), and bolted connections can loosen. Always have a certified,
reputable bike mechanic perform a tune-up on your SINCH after your initial
break-in period of 50-100 mi (80-160 km) (depending on riding conditions such
as total weight, riding characteristics, and terrain). Regular inspections and
tune-ups are particularly important for ensuring that your bike remains safe
and fun to ride.
Tire Information
SINCH uses 20″×4″ rubber tires with inner tubes. The tires are designed for
durability and safety for regular cycling activities and to be checked before
each use for proper inflation and condition. Proper inflation, care, and
timely replacement will help to ensure that your bike’s operational
characteristics will be maintained, and unsafe conditions avoided.
Aventon Bikes recommends 5-30 PSI for the stock tires on SINCH. Always stay within the manufacturer’s recommended air pressure range as listed on the tire sidewall.
Note: It is critically important that proper air pressure is always maintained in pneumatic tires. DO not underinflate or overinflate your tires. Low pressure may result in loss of control and overinflated tires may burst. Failure to always maintain the air pressure rating indicated on pneumatic tires may result in tire and/or wheel failure.
Inflate your tires from a regulated air source with an available pressure gauge. Inflating your tires from an unregulated air source could overinflate them, resulting in a burst tire. Even tires equipped with built-in flat- preventative tire liners, like those that come with bikes by Aventon Bikes, can and do get flats from punctures, pinches, impact, and other causes. When tire wear becomes evident or a flat tire is discovered, you must replace the tires and/or tubes before operating the bike or injury to operators and/or damage to your bike could occur.
When changing a tire or tube, ensure that all air pressure has been removed from the inner tube prior to removing the tire from the rim. Failure to remove all air pressure from the inner tube could result in serious injury. Using aftermarket tires or inner tubes, not provided by Aventon Bikes may void your warranty, create an unsafe riding condition, or damage to your bike by Aveton Bikes. frequired by law, ensure replacement aftermarket tires have sufficient reflective sidewall striping.
For more information on tire or tube replacement procedures, or questions
about tire
inflation, contact Aventon Bikes Product Support.

Additional Information on Wear
Components of SINCH are subject to higher wear when compared to bikes without
power assistance. This is because SINCH can travel at higher average speeds
than regular bicycles and has a greater weight.
the tires, brake pads and rotors, suspension forks, spokes, wheels, and the
battery.
NOTE: when the useful life of a component is surpassed it can cause an unexpected loss of function. This can result in serious injuries or even death. Therefore, pay attention to wear characteristics such as cracks, scratches, or changes in the color or operation of components which could indicate useful life has been exceeded. Worn components should be replaced immediately. If you are unfamiliar with regular maintenance, a certified, reputable bike mechanic should be consulted.
