maintenance, and other helpful tips for owners. Read it carefully and familiarize yourself with
the ebike before using it to ensure safe use and prevent accidents. This manual contains
many warnings and cautions concerning the safe operation and consequences if proper
setup, operation, and maintenance are not performed. All information in this manual should
be carefully reviewed and if you have any questions you should contact Gopowerbike
immediately.
The notes, warnings, and cautions contained within the manual and marked by the triangular
Caution Symbol at the right of this page should be given special care. Users should also pay
special attention to information marked in this manual beginning with NOTICE.
Keep this manual, along with any other documents that were included with your bike, for
future reference, however all content in this manual is subject to change or withdrawal
without notice. Gopowerbike makes every effort to ensure the accuracy of its documentation
and assumes no responsibility or liability if any errors or inaccuracies appear within.
Assembly and first adjustment of your bike from Gopowerbike requires special tools and skills
and it is recommended that this should be done by a certified, reputable bike mechanic if
possible.
Because it is impossible to anticipate every situation or condition that can occur while riding,

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, Gopowerbike recommends having a certified, reputable bike mechanic check your work.
NOTICE: If you do not have the experience, skill, and tools to complete assembly and fit, Gopowerbike
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 by Gopowerbike is securing the front wheel and
checking the tightness of the rear wheel axle nuts. All bikes by Gopowerbike use a 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 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. 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, invalidate your
warranty and, in some cases, cause your ebike to not conform with laws pertaining to your bike.

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. See the Pre-Ride Safety
Checklist for more information.
Electrical System
The electrical system on your ebike 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
ebike’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 ebike immediately
and contact the Gopowerbike Product Support team for assistance.
Quick Release Levers
Quick release levers are located on your ebike to secure the seatpost and the front wheel to the bike.
These provide convenience to the user since they allow the front wheel to be removed and the seatpost
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.
4
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 find something you are not sure
about, have it checked by a certified, reputable bike mechanic.
Suspension, Handlebars, Grips, and Seat Adjustments
The suspension fork on your ebike will affect the handling of the bike so you must 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 be purchased from Gopowerbike. 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. The battery gauge on the LCD display
and charge status indicator on the battery should read similarly. Ensure the battery charger is unplugged
from the outlet and 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.

Assembly Instructions
Folding and Unfolding the Frame
NOTICE: The following steps are only a general guide to assist in the assembly of your ebike and are not a
complete or comprehensive manual of all aspects of assembly, maintenance, and repair. Consult a
certified, reputable bike mechanic to assist with assembly, repair, and maintenance of your ebike.
Step 1: Unpack the bike. Open the bike box and remove the small box inside. With the help of another
person capable of safely lifting a heavy object, remove the GoExpress from the bike box. Carefully remove
the packaging material protecting the bike frame and components. Please recycle packaging materials
especially cardboard and foam whenever possible. Open the small box and carefully set out all contents.
Ensure all the following pieces are included with your GoExpress:
•Manual
•Assembly Toolkit
•Pedals (marked left and right)
•Handlebar
•Charger
•Keys (two, identical)
•Seat
If there are any missing parts, please contact GoPowerbike.
Since hand oils can cause squeaking and decrease brake performance, do not touch the brake
rotor while inspecting, opening, or closing the quick release lever. Never touch the brake rotor,
especially when the wheel and/or bike is in motion, or serious injury could occur.
7
Step 2: Unfold handlebar stem. Insert the handlebars into the handlebar stem and close the quick release
clamp, as shown below. Then carefully rotate the handlebar stem upwards and close the bottom hinge.
8
Step 3: Unfold the bike. Turn the front wheel slightly to the right until the frame is unfolded and both
sides of the central hinge are touching.
9
Step 4: Secure central hinge. Pull directly upward on the quick release lever to lift the hinge pin, and at
the same time, push the bike frame together so the hinge is fully closed.
Step 5: Complete unfold. Swing the frame hinge quick release lever toward the front of the bike so it is
parallel to the frame. Fold the quick release lever downward to securely lock the frame hinge.
10
Step 6: Install the pedals. Locate the pedal with a smooth pedal axle exterior and an “R” labeled on the
pedal, which indicates that it is the right pedal. The right pedal goes on the crank on the right side of the
bike (which has the drivetrain gears and is the same as a rider’s right side when riding).
The right pedal (1) is threaded by turning clockwise (toward the bike’s front). Carefully thread the right
pedal onto the crank on the right side of the bike slowly and by hand. Do not cross thread or damage the
threads.
The left pedal (2) is reverse-threaded and tightens counterclockwise (toward the front of the bike).
Ensure the remaining pedal has notches on the exterior of the axle and an “L” labeled on the pedal,
indicating that it is the left pedal. Carefully thread the pedal onto the left crank by hand slowly. Do not
cross thread or damage the threads.
Torque each pedal to 35 Nm. Use a pedal wrench to avoid damage caused by wider wrenches.
IMPORTANT: The left pedal (left image) tightens counterclockwise, the right pedal (right image) tightens
clockwise, both towards the front of the bike.
NOTICE: GoExpress pedals are designed to fold by pressing the pedal end directly toward the crank and
then folding. Use caution to keep fingers, clothing, etc. away from the folding parts and potential pinch
points. Ensure the pedals are locked in the unfolded position before each ride.
11
Step 7: Inflate the tires. Check that the tire beads and tires are evenly seated around the rims. Use a
pump with a Schrader valve and pressure gauge to inflate each tire to the recommended pressure
indicated on the tire sidewall. Do not overinflate or underinflate tires.
12
Step 8: Set the desired seat height. Open the quick release lever by hinging it open fully. Ensure the
seatpost clamp opening is aligned with the notch at the front of the seat tube. Adjust the seatpost up or
down to a comfortable height, while ensuring the seatpost is inserted into the frame past the minimum
insertion point.
If needed, use the thumb nut to add tension to the clamp so there is some resistance when the lever is in
line with the clamp bolt, but do not overtighten. Close the quick release lever to secure the seatpost and
check that it cannot move. See the Adjusting the Seat section of this manual for more details.
13
Step 9: Review the remainder of the manual. Once the bike has been assembled per the above
instructions and the assembly video available from GoPowerbike, read, understand, and follow the
procedures outlined in the remainder of the manual before operating the bike.
NOTICE: If you have any questions regarding the assembly of your bike, contact GoPowerbike. If you are
not able to ensure all the assembly steps in the assembly video are performed properly, or you are unable
to view the assembly video, please consult a certified, reputable local bike mechanic for assistance in
addition to contacting GoPowerbike for help.
NOTICE: Ensure all hardware is tightened properly following recommended torque values and all safety
checks in the following sections are performed before the first use of the bike.
Do not extend any components including the handlebar stem, seatpost, or seat saddle
beyond any minimum insertion marking etched into the components. Ensure that all
hardware is properly tightened (to the values in the Recommended Torque Values table)
and components are secured before moving on to the next step, otherwise damage to the
bike, property, serious injury, or death could occur.
Step 10: To fold the frame and securely lock the central frame hinge, reverse the steps above.
14
Adjusting Seat Height
For most users, the seat height should be set by placing the ball of their
foot on the pedal when the crank is at its lowest point. In this
orientation their leg should almost be fully extended, with a slight bend
at the knee. The correct seat height should not allow leg strain from
overextension and the hips should not rock from side to side when
pedaling. To adjust the seat height:
1. Open the quick release lever by swinging the lever open and
outward fully.
2. Move the seat up and down by sliding the seatpost in or out of the
seat tube. Set the desired seat height.
NOTICE: Ensure the seatpost and seat are properly adjusted before
riding. DO NOT raise the seatpost beyond the minimum insertion
marking etched into the seatpost tube. If the seatpost projects
from the frame beyond these markings (shown far right), the
seatpost or frame may break, which could cause a rider to lose
control and fall. Ensure the minimum insertion markings on the
seatpost are inside the seat tube of the frame.
3. After tightening the adjustment nut (opposite the quick release
lever) on the seatpost quick release properly, close the quick release
lever fully so it looks like the image at right and the seat cannot
move up, down, to the left, or right.
15
Before using the bike, always check to ensure that the folding mechanism locks on the
central
frame hinge, handlebar stem hinge, pedals, and seatpost quick release lever are
properly and securely locked. Check that they are correctly secured before every ride
and after every time the bike is left unsupervised, even for a short time. Otherwise,
the handlebar stem and/or seatpost may come loose and can result in loss of control,
damage to the bike, property, serious injury, and/or death.
Adjusting the Seat Position and Angle
To change the angle and horizontal position of the seat:
1. Use a 6 mm Allen wrench to loosen the seat adjustment bolt on the clamp positioned immediately
underneath the seat, above the rear wheel. Do not remove the bolt fully.
2. Move the seat backward or forward and tilt to adjust the angle. A seat position horizontal to flat
ground is desirable for most riders. Do not exceed the limit markings on the seat rail, which show the
minimum and maximum horizontal movement allowed.
3. While holding the seat in the desired position, use a 6 mm Allen wrench to tighten the seat angle
adjustment bolt securely to the recommended torque value.
Prior to first use, be sure to tighten the seat clamp via the seat adjustment bolt
properly. A loose seat clamp or seatpost adjustment bolt can cause damage to the
bike, property, loss of control, a fall, serious injury, or death. Regularly check to make
sure that the seat clamp is properly tightened.
16
Rider Comfort
Depending on a rider’s preference, ability, and amount of experience with bike and ebike riding, lowering
the seat so the rider can put one or both feet on the ground without dismounting from the seat may offer
a safer and more comfortable experience while operating the bike.
Generally, for the most comfortable riding position and best possible pedaling efficiency, the seat height
should be set correctly in relation to the rider’s leg length, as described in the Adjusting the Seat Height
section, allowing the knee to be slightly bent with the ball of the foot on the pedal and the pedal at the
lowest point at the bottom of the pedal stroke.
To obtain maximum comfort, riders should not overextend their arms’ reach when riding. It is generally
advised to ensure the handlebar and brake lever angles allow for a comfortable arm position and
relatively straight line from forearms, wrists, and hands. Ensure the handlebar angle is adjusted so that it
allows the handlebar to remain clear of the rider’s body while turning.
A bike fitting professional, such as a certified, reputable bike mechanic who specializes in bike fit, should
be consulted to ensure you have a good fit.
NOTICE: If you have any questions regarding the proper fit of your bike please consult a certified,
reputable local bike mechanic for assistance fitting the bike to a rider or contact GoPowerbike.
