General Info
Assembly and Fit
Correct assembly and fit are essential elements of ensuring your bicycling safety,
performance, and comfort. Even if you have the experience, skill, and tools to
complete these essential steps before your first ride, Senada Bikes recommends
having a certified, reputable bike mechanic check your work.
NOTICE: If you do not have the experience, skills, or tools to complete assembly
and operation, Senada Bikes highly recommends having a certified, reputable bike
mechanic complete these procedures as well as any future adjustments or

9
tuning.operation
NOTICE: A critical aspect of assembling your bike by Senada Bikes is securing the
front wheel and checking the tightness of the rear wheel axle nuts. 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 all rides, ensure you have all required and recommended safety equipment
and are following all laws pertaining to using an electric bike in your region.
Changing Components or Attaching Accessories
The use of non-original components or spare parts can jeopardize the safety of
your e-bike, void your warranty, and, in some cases, cause your e-bike to not
conform with laws pertaining to your bike.
Safety Check Before Each Ride

10
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
The electrical system on your e-bike offers various levels of power assistance and
lighting for different operating conditions and user preferences. It is critical that you
familiarize yourself with all aspects of your bike’s electrical system and check to see
that it is working correctly before every ride.
The front and rear brake levers contain safety power cutoff switches, which disable
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.
If the throttle, brake lever cutoff switches, pedal assistance, or lighting are
functioning abnormally, intermittently, or not working, please discontinue using your
e-bike immediately and contact the Senada Bikes Support Team for assistance.

11
Brakes
Ensure brakes are working correctly, all braking system components are free from
damage and properly secured. When you fully squeeze the brake levers, ensure
neither the front nor rear brake levers touch 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
the 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 Senada Bikes.
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, in case
of tire and component wear, and make your riding unsafe.
Quick Release Levers
There is a quick-release lever located on your e-bike for securing the seat tube. This

12
provides convenience to the user since they allow the seat tube to be adjusted
without tools. Since quick-release levers can be loosened during transportation, or
accidentally between or during rides, it is important that you regularly check to
ensure these components are properly secured.
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 is wrong or find something you are not sure about,
have it checked by a certified, reputable bike mechanic.
Suspension, Handlebar, Grips, and Seat Adjustments
The suspension fork on your e-bike will affect the handling of the bike, you need to
understand how it works before use. The suspension fork should be properly adjusted
for your weight and terrain. Ensure the handlebar and handlebar stem are properly
aligned, fitted to the user, and secured to their recommended torque values.
Handlebar grips should not move easily on the handlebar end.
Loose, worn, or damaged handlebar grips should be replaced before you ride and can

13
be purchased from Senada Bikes. The seat and saddle tube should be properly
aligned, and fitted to the user, and the saddle tube 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. The battery
gauge on the LCD display and the charge status indicator on the battery should
read similarly. Ensure the battery charger is unplugged from the outlet, battery,
then stored in a safe location before you ride.
