Bakcou Mule/Flatlander Assembly
Required Tools:
●MAKE CERTAIN TO PAY ATTENTION TO ALL BOLD ITALICIZED TEXT
●We recommend using medium grade Loctite on any bolts that seem to loosen while
riding
●Cutting Pliers (to cut box poly strapping and heavy bike banding)
●Scissors (to remove bubble wrap)
●Allen wrenches (3mm, 4mm, 5mm, 6mm)
●Wrenches (10mm, 15mm)
●Approximate Assembly Time: 20 - 30 minutes
UNBOXING AND REMOVING BUBBLE WRAP/BANDING
1. Cut banding straps from exterior of box and open box.
2. Remove “Tool Kit” box containing pedals, headlight, battery charger, and hardware from
box.
3. Remove bike from box. (If necessary, lay box on side and slide out or use two people to
lift out)

4. Cut banding straps to release the front tire from the frame of the bike. (Use caution in
cutting banding straps, paying particular attention to brake, derailleur and all other
cables on bike)
5. Cut banding straps to remove front and rear fenders from the front tire. (Rear fender
may already be assembled on bike)
6. Cut banding straps to release handle bars from the frame of the bike. (Avoid letting
handlebars hang for extended periods and thus putting stress on cables. Make certain
cable connections have not pulled apart during this step or in shipping)
7. Remove remaining bubble wrap, foam, and shipping materials as needed to protect the
bike during assembly. Note: Make certain to remove plastic (if present) from both sides
of the motor to allow for ventilation while operating.
HANDLEBAR ASSEMBLY
8. Using 4mm Allen wrench remove 4 screws from bicycle stem (See Picture Below)
9. After removing the front plate of bicycle stem insert center of handle bars into bicycle
stem and replace front plate and 4 screws to secure handlebars. (Make certain
handlebars are positioned with the throttle to the left and the rapid-fire index shifting
levers on the right. Slightly insert each of the 4 screws prior to tightening. Also, prior to
tightening, rotate handlebars forward or backwards to customize position of handlebars
to rider) Note: most often brake levers should be angled approximately 45 degrees
downward for optimal positioning.

10. Display screen is easily rotated by hand forwards or backwards to customize to rider.
PUTTING ON FRONT TIRE
11. If present, remove plastic spacer from bottom of front forks.
12. Loosen quick release hub on both sides of front hub axle (axle of front wheel).
13. If present remove plastic insert from between front brake pads (do not squeeze brake
levers after removing this plastic insert before installing the front tire).
14. Slide quick release axle into the ends of the front forks and the front brake rotor
between the brake pads and tighten.

PUTTING ON PEDALS
15. Remove pedals from “Tool Kit” box.
16. Differentiate the right pedal from the left pedal by locating the small “CR-L” (for the left)
and “CR-R” (for the right) inscribed on the bolt of the pedal. (See Picture)
17. Attach right pedal by screwing into right crank in clockwise pattern using 15mm wrench
(Note: recommend using a medium grade Loctite to ensure bolt does not loosen)
18. Attach left pedal by screwing into left crank in counterclockwise pattern using 15mm
wrench (Note: It is recommended that you use a medium grade Loctite to ensure bolt
does not loosen)
19. Make certain crank bolts are tightened using 10mm Allen wrench (Note: It is
recommended that you use a medium grade Loctite to ensure bolt does not loosen)

FRONT FENDER & HEADLIGHT ASSEMBLY
20. Attach front fender and headlight to front fork bracket using long bolt from hardware
package, 5mm Allen wrench, and 10mm wrench (Note: Place light bracket and fender
bracket on the backside of the fork bracket) After tilting headlight forward to expose
backside, plug red (positive wire) into the left side of the head light and black (negative
wire) into the right side of the head light.
ATTACHING REAR FENDER
21. If not already assembled, slide the rear fender under the pannier rack and attach to the
seat post using a 5mm Allen wrench. (Note: Two shims are included with the rear
fender, use the thinner of the 2 shims and discard the thicker shim. Attach to the seat
post as shown below making sure to attach just under suspension of the seat post so as
to allow for a wider range of raising/lower seat post. Rear fender can be micro adjusted
using plastic bolts and may require adjustment on seat post to fit fluctuating rider
heights)

22. Optional: Drill two small holes in rear fender just below center cross beam of pannier
rack and fasten rear fender to pannier rack using zip tie to stabilize fender. (See photo
below) (Note: This will slightly limit ability to raise or lower seat post for riders of
different heights)
READ BEFORE USE
23. Make sure to check all nuts and bolts to ensure they have not loosened during shipping.
24. Battery typically has partial charge straight from box. Fully charging prior to initial use is
recommended. Battery can be charged while on bike or it can be removed and charged
off of bike.
25. Keys are only used to remove battery from bike. Simply insert key into lock and turn,
while pulling out and up on battery handle to remove battery.
26. To re-insert battery, key is not needed: simply place bottom of battery into lower slot
and firmly push top of battery into upper slot. (Note: make sure battery is locked firmly
into place prior to riding as a loose battery may cause inadvertent loss of power or
battery may fall out of chamber and become damaged. After reinserting, check battery
attachment by pulling out and up on handle to ensure it is securely fastened)
27. Assembly is now complete: However, minor adjustments are often necessary to
precisely fit ebike to rider. These adjustments can include rotating locking handle grips,

moving/rotating brake levers, throttle and shifters. These adjustments are easily
performed. However, feel free to contact us via email or phone with any questions.
28. Note: A Suspension Adjustment video and Display Use video can each be viewed under
“Support” on the Bakcou website. Note: located at the bottom of some right front forks
is a blue knob called a shock dampener. This knob is used to control the rebound
speed of the fork. Knob can be twisted clockwise to close or counter-clockwise to
open, thus allowing more or less air flow to increase/decrease rebound speed. Make
certain to tighten the screw inside the dampener knob and we recommend using
Loctite on the threads to keep screw in place. After tightening screw tighten
(clockwise) the dampener knob and then back off 1 ½ turns. After getting used to your
Mule’s suspension adjust accordingly.
29. Two “green” rolls of puncture proof tire liners may be located in the bike box or in the
tool kit box. The liner goes in between the tube and the tire. Liner was not installed at
the factory as some riders prefer to use a tube sealant such as Flat Out. The liner will
add some weight to the tire and does affect the flexibility of the rubber thus slightly
changing how the tire rolls across some terrain. We strongly encourage using the
puncture proof liner when riding in areas with heavy “goat heads” or other tube
puncturing thorns. (Bakcou YouTube instructional video available on line)
30. Regular and routine maintenance of your ebike is not only recommended, but highly
essential to ensure proper function, safety, and longevity of your ebike. See owners
manual for further instruction.
31. Always wear a helmet and other protective gear while riding.
32. Always know and observe traffic and trail laws and regulations.
