1. INTRODUCTION
Congratulations on the purchase of your new Yuba elMundo/eZee Hybrid-electric Cargo Bike. You
have taken a very significant step toward realizing a whole new way of transportation for commuting
and those short grocery trips that is fast, fun, efficient, and friendly to our environment. The eZee hub
motor is brushless and uses a technology called Pulse Wave Modulation Control, meaning the wear of a
traditional brushed DC motor is eliminated. Translation: far lower maintenance costs and very long
life.
Planetary reduction gears incorporated into the hub provide high torque in a compact and light weight
package which works with you to flatten out those pesky hills and still those ferocious headwinds.
Under normal cruising conditions (26 kmh/16 mph) the motor draws about 5 amps at 140 watts with 5
Nm of torque and has an efficiency of around 80%. The electric consumption is about 1.0 kwH for 100
km/62 miles in ebike mode – even less energy than the food consumed under leg power alone! Making
it by far one of the most efficient vehicles ever made!
While the Yuba/eZee pledge to quality means our components are of high value and reliable, it is your
responsibility to understand the safety implications and possible risks of cycling, particularly when
adding the extra speed electric-assist systems allow. So please take the time to read this manual, which
details the basic elements of care and use, as well as visit our website electric-cargo-bike for more in-
depth information. There you will find videos and articles to further guide and instruct. With simple care
and attention, your new Yuba elMundo Electric Cargo Bike will bring you many years of reliable use. Please
feel free to email [email protected] with specific questions or comments. We encourage and
appreciate your feedback!
Note: For assembly instructions regarding the Mundo Cargo Bike, please refer to the Mundo manual or
assembly sheet.
2. LEGAL REGULATIONS
European Union
EU regulations state that your vehicle is an Electric Powered Assist Cycle (EPAC) when the following
conditions are met, and is now governed by the latest European regulation EN15194:2009 for EU.
Extract [ EU directive 2002/24/EC Chapter 1 Article 1 1(h) ]
“Cycles with pedal assistance which are equipped with an auxiliary electric motor having a maximum
continuous rated power of 0.25 kW, of which the output is progressively reduced and finally cut off as the
vehicle reaches a speed of 25 km/h or if the cyclist stops pedaling.”
Conforming to EN reg., the power assist of the eZee motor/ battery can only function while the rider is
pedaling. The means of controlling the power level of the assistance is provided with either a dial or
throttle system.
North America
In the USA it is governed by Consumer Product Safety Commission 16 CFR Part 1512 requirements for low
speed electric bicycles. The regulations allow a power assisted maximum speed

Yuba Bicycles LLC elMundo Electric Cargo Bicycle [ Owner’s Manual ] Page 2
of 20 mph. The eZee motor/battery made for the USA has a motor rated at 350 watts up to a max of
700. The power assist can function without the aid of pedaling, should you choose to. However, as a
Human-electric hybrid drive system, the more you pedal, the more speed and range will be gained.
As a legal low speed electric assist bicycle, you are not required to have a license, there is no age
limitation, and you are allowed on all cycling paths. It is regulated as a normal bicycle. Legal
requirements concerning insurance of your bicycle may differ by location, so please find out about any
rules and regulations in your country.

5. ASSEMBLY
Please refer to the Mundo assembly sheet and elMundo assembly sheet regarding the assembly of the bike
and its components.
The elMundo Bicycle carton should contain:
• 1 elMundo Cargo Bike (7 Speed) with electric front wheel installed, electric components mounted and a
battery installed into the frame.
• 1 part box with pedals, stem and Owner’s manual & Assembly instructions.
• 1 small box with electric charger, 2 30 amp fuses, zip ties.
• 3 Ignition lock key attached to the handlebars.
Front wheel: The front wheel is assembled. But in case you need to remove the front wheel and reinstall
it, please respect the following guidelines. Insert the hub motor wheel into the fork, ensuring that it is
properly seated in the dropout slots. Tighten the nuts on both sides evenly until the wheel is secured. Be
sure to use the torque arm washer (and bolt it to the fork)! Also, it is a very good idea to check the tightness
of the bolts periodically, as they could loosen during use. Tightening torque value is 35 Nm. We stronlgy
recommend placing the bike upside down to remove or insert the front wheel.
Battery: Locate the keyhole by the controller box and turn the key counter clockwise while pressing in,
this will release the lock pin. Ensure that you keep the key in the “Lock” position until you are ready to ride.
When installing the battery, do not use excessive force, as this could damage the battery or the connection
pins. If there is an outlet near where the bike will be parked, it is not necessary to remove it. However,
avoid leaving the battery out in cold weather, as this could damage the cells and degrade its performance.
Keys: 3 ignition/lock keys are provided, please safely store any keys not in use where you can find
them. Use only one key at a time! It is not uncommon to have customers lose all 3 keys!

6. OPERATING:
To learn more about operating the Mundo Cargo Bike refer to the Mundo Owner’s manual.
Battery Charging:
Locate the keyhole by the controller box and turn the key counter clockwise while pressing in, this will
release the lock pin. If you wish to be able to remove the battery from the bike easily, you will need to cut
the forward portion of the utility deck off. Ensure that you keep the key in the “Off” position until you are
ready to ride. When installing the battery, do not use excessive force, as this could damage the battery or
the connection pins. If there is an outlet near where the bike will be parked, it is not necessary to remove it.
However, avoid leaving the battery out in cold weather, as this could damage the cells and
degrade its performance.
Before your first ride, the battery needs to be fully charged. Plug the charger into the battery charge
port (located on the top left side under a rotating cover) near the key, make sure the charger switch is in
the off position, plug the charger into a wall socket (220V - 230V AC EU other countries or 115V AC US)
or extension cord, then switch the charger on. You should see a green light which will cycle to yellow when
it begins charging. The sound of the fan running indicates charging has been initiated. When the light is
green again, the battery is fully charged. Do not remove the charge plug by pulling the cord, always
grip the metal when pulling.

•It will take roughly 3 hours to charge to 10ah battery, and around 4 to charge the 14ah battery.
You may interrupt the charging at any time.
•Lithium batteries do not suffer from “memory” effects, so it is not necessary to discharge the
battery totally before charging. In fact, it is best to charge the battery whenever possible..
•Used with proper care, your Lithium battery will perform at least 350 full charge cycles retaining
at a minimum 70% of it's original capacity.
Please use only the charger as provided.

A new battery may take 2-3 charges before it performs to it's full capacity. Occasionally after a
temporary disconnect, the charge light may indicate a false green. To verify complete charging, switch
the charger off, wait a few seconds, then switch it back on. It should cycle from amber to green very
quickly if fully charged.

Yuba Bicycles LLC elMundo Electric Cargo Bicycle [ Owner’s Manual ] Page 6
If the battery refuses to accept a charge, refer to your dealer for further support.
Battery charging is automatically regulated, so there is no danger of overcharging. It is advised to
disconnect and switch off the charger when complete.
Do not charge the battery in wet conditions.
Never allow children to play with the battery or charger.
Do not leave your battery in a fully discharged state, as this will damage the cells.
If storing for extended periods, charge fully; and if possible, arrange for it to be charged at least
once a month to maintain cell health.
7. HOW THE EZEE/ YUBA elMUNDO WORKS
Before your first ride, we recommend you practice handling the bike in a safe, traffic-free area. The
motor may look small, but it's powerful! With the extra speed it allows, you will need to take special
care while adjusting to its capabilities. Please visit our website for more detailed instructions on the
use and care of your new Yuba/eZee elMundo. yubaride.com/electric-cargo-bike
EPAC/Pedelec: As you pedal, a sensor picks up the motion and allows the drive system to be engaged.
A twist of the throttle then provides power-on-demand.
E-Bike: The motor runs as soon as you engage the throttle. Ensure that you are ready to ride before
you use the throttle.
In E-Bike mode, the range of your bike will be approximately 40kms (25 mi.) which will vary depending on
your effort, the terrain, and the cargo load. With EPAC, judicious use of gears and your own efforts
contribute to a range of around 40-60kms (25-40 mi.). As you use the system, you will gain a better sense of
range that will allow you to plan your trips without fear of running out of juice! And, you can always carry
your charger with you.
Please refer to the website for detailed instructions on the use of the Cycle Analyst computer, and it's
ability to precisely monitor your battery state. With proper planning and monitoring, you should never
run out of power if you wish to avoid that.
Battery level gauge: When riding a fully charged bicycle, the battery level gauge shows ‘green’.
Powerful acceleration or uphill riding causes the battery voltage to drop and may bring the level gauge to
‘amber’ or even ‘red’ (in the cases of very steep hills). As you continue to cycle and the battery power drops,
the level gauge will correspond to the state of charge remaining. When it remains in ‘amber’ and dips into
‘red’, you have approximately 20% of the charge left. Best to recharge the battery soon.
Continued use of an empty battery by ‘pulsing’ will cause deep discharge, this is detrimental to the battery
and reduce its life.
Lock: When parking your bike, turn the key to the “Off” position and remove it. This will shut the
system off and lock the battery in place. And of course, use a strong lock to secure your bike properly.
We also recommend insuring your bike against theft. Consult your dealer for more information.

Yuba Bicycles LLC elMundo Electric Cargo Bicycle [ Owner’s Manual ] Page 7
8. MAINTENANCE
Tire puncture: If you have the misfortune of experiencing a
puncture, we recommend bringing it to a bike shop to carry out the
repair. You can of course do it yourself if you're comfortable with
such repairs; but be aware that the hub motor requires some extra
steps. Be sure to have the correct tools if you intend to complete this
repair yourself. This requires a 19mm box wrench for both front and
rear wheels, as well as a small phillips-head screwdriver for the
junction box on the fork. Be mindful of the order of things, and be
sure to replace everything correctly.
We recommend to position the elMundo upside down to remove or
insert the front wheel with the hub motor.
Hub Motor and General Inspection: After 5,000kms (3,000 mi.) of cycling, we recommend arranging to
have a thorough inspection of your system at a dealer. This includes opening up the hub motor to inspect
and lubricate the gears. Proper maintenance will significantly extend the life and performance of your
Yuba/eZee elMundo.

9. TROUBLESHOOTING:
Electronic self-diagnostic system
When the system is functioning normally, the red LED on the controller near the battery is lit continually. In
the case of a malfunction, the controller is programmed with diagnostic capabilities to determine where the
fault lies. The red LED will emit a series of blinks, count them and refer to the table below.
If there is no power to the motor, and the red LED diagnostic light is on, open the junction box at the
fork and check to ensure all connectors are properly seated. Loose connectors are very often the source
of common issues. The faults listed do not cover all possible failures. In the event of moisture entering the
controller, motor, etc., haphazard signals may appear. Storing the bike in a dry, heated spot will usually
cure this. Since this manual cannot cover every possible eventuality, please refer to our website for more
details and tutorials; or contact us directly with any questions you may have.
