Yuba FAQ

Where can I find the serial number on my Mundo V5 & elMundo V5?

The serial number on the Mundo V5 & elMundo V5 can be found stamped on the bottom bracket shell.

Do I have to wear a helmet when riding an electric bike?

California State Law requires that all people riding electric bikes wear approved helmets. Check with regulations in your local area.

How do you carry kids on a Yuba Mundo? When are they old enough?

The Yuba Mundo can be configured to accommodate children of all ages – from babies to toddlers, rug rats to tweens, and beyond.

In general, the American Medical Association recommends that children can be transported on a bike in a child seat, such as the Yepp Maxi, from when they can hold their head upright (about 12 months or 20 pounds) to about 36 months or 36 pounds. To give parents more security, we made sure it will accommodate kids up to 48 months old or 48 lbs. That being said, children get bigger faster or slower, and are ready to move to sitting on the Soft Spot at different ages. It really depends on the temperament of the child.

The next set up after the Yepp Maxi would be setting up the Mundo(make sure wheelskirts are installed) a Leg Up, Soft Spots, and either Monkey Bars or a Hold On Bar. If you’re taking a lot of short trips with a lot of ons and offs, then Hold on Bars are ideal, if you have two or more kids to haul longer distances, and they like to interact with (tickle) each other or fall asleep, the Monkey Bars are more ideal.

Once the kids get to be a bit bigger, and their feet can reach the Sideloaders, you probably will want to get Bamboo Boards or a Running Board and a Towing Tray. A Rumble strap can be added for increased security after they’ve outgrown the Monkey Bars.

Can I install pedal assist on my Boda Boda V2?

Yes! Over 70% of our bikes eventually have pedal assist systems installed. Whether front or rear hub motor or bottom bracket-mounted mid-drive, the Boda Boda V2 is ready to be converted to the system of your choice. We’ve even provided extra room under the rear deck to mount a battery; contact us about our battery bracket for an easy mounting option.

Here is an example of our elBoda Boda that we build with the BionX pedal assist system:

What are the differences between the SO & the ST versions?

The main differences between the Step Through and Step-Over frames are a few key measurements, allowing a wider range of people to fit the bicycle. As you can see in the chart below, the Step-Through has a shorter reach from the saddle to the handlebars,  a shorter steer tube and a much lower top tube which creates the step-through portion of the frame.

Where can I test ride a bike?

We have an ever-expanding dealer network in America and abroad! You can find the closest dealer to you using our online dealer locator.

How much assembly is necessary?

Our bikes are shipped about 85% assembled and securely packed. When your bike arrives, final assembly and tuning should be performed by a qualified bicycle mechanic to ensure the safety of both the rider and passenger(s). The mechanic should have experience with headset bearing assemblies, derailleur systems and either rim or disc brake systems.

Can I install electric pedal assist on my Mundo?

Yes! Over 70% of our bikes eventually have pedal assist systems installed. Whether front or rear hub motor or bottom bracket-mounted mid-drive, the Mundo is ready to be converted to the system of your choice. There are standard water bottle cage mounts on the downtube to mount your system’s battery.

Important note:

The Mundo V3 and V4’s rear dropouts take a 14mm axle. Standard axles are 12mm or 10mm. A rear hub motor will require the proper axle adapters to be able to work with the Mundo V3 or V4 frame.

For flattened rear axles, you will want to use our Slotted Axle adapters.

For front hub motors, you will want to use our Anti-Rotation washer.

If you plan to use a BionX kit, please contact us to determine whether the system you want to use is compatible with the Mundo V3 or V4.

The Mundo V5 uses standard 3/8″ (or 10mm) vertical rear dropouts.

Can the Boda Boda V2 have multiple front chainrings for wider gearing?

Yes, it’s definitely possible to add multiple chainrings and a front derailleur to the Boda Boda V2. The stock bottom bracket will accept any JIS Square taper modern crank (double or triple chainring); its spindle length is 110.5mm .

The bottom bracket shell will also accept external bearing bottom brackets; its shell dimensions are 68mm wide, English thread (1.37 in x 24 TPI).


Do you have Monkey Bars for the Boda Boda V2 or V3?

We do not currently make Monkey Bars for the Boda Boda V2, but it’s possible to convert the Mundo’s Monkey Bars for use on the Boda Boda’s shorter deck. You can find the step-by-step process and materials list on our website.

The Boda Boda V3 is compatible with our Mini Monkey Bar.

Where can I find the Serial Number on my Boda Boda V2 and V3?

The serial number of your Boda Boda (or elBoda Boda) can be found under your bike stamped into the bottom bracket shell between the pedals.

What’s the biggest tire I can install on my Mundo?

It’s possible to install a 2.5″wide tire with the stock drive train and fenders.

Tires up to 3.5″ wide will require a custom drive train providing more clearance for the chain line; there will not be sufficient clearance for full fenders with a tire this wide.

Do I have to use the Yepp Maxi childseat?

Because the integrated rear racks of our cargo bikes are extra wide a standard child seat won’t fit over the rack.  The Yepp Maxi child seat is the only child seat we’ve found that is compatible with our cargo bikes. 

Mundo V5, Boda Boda V3, Spicy Curry, Sweet Curry and Supermarché all have integrated mounting brackets for the Yepp Maxi.  The seat installs in seconds with the turn of a dial.

Note: For Boda Boda V2 and Mundo V4 or older, you’ll need a Yepp Maxi Easyfit Adapter.

What car rack do you recommend for the electric Cargo Bike?

The big challenge with electric bikes on bike is the additional weight of the motor systems, which typically add ~15-20 pounds to a bike. We recommend The Hollywood Racks Sport Rider for Electric Bikes (HR1450E). It is an easy-to-use hitch mounted rack that fits standard 2″ trailer hitches on cars or trucks. Designed for the additional weight of electric bikes, it has the capacity for two elMundos . The sliding wheel supports make it easy to adjust to longer wheelbase bikes, such as the Mundo, and also fit a shorter wheelbase bike such as a Boda Boda or a road bike.

Putting the bikes in the rack is easy, even for people with less upper body strength. Simply lift up the front wheel, and place it in the rack, and then lift the rear of the Mundo up by it’s frame and pop it into the rack.

We  were concerned that the sideloaders would rub and scratch the paint on the second bike. In our test, this did not happen, because the sideloaders rubbed up against the rubber of the tires on the second bike. If it was a major concern, a user could tape or zip tie some cardboard between the bikes to prevent any contact at all.

The rack conveniently folds up against the vehicle when not in use.

**Please remember if driving with an electric bike to remove the batteries before putting your electric bike on a car rack, because the vibrations of the road can decrease battery life.

Do I need a special license to ride an electric bike? How old do I have to be?

In general, adults don’t need a license or permit to ride an electric bike in the United States. In some states, there are age limits and permitting requirements for teenagers.

Electric bike laws vary state to state, you can find the specifics for your state here.

Will these bikes REALLY improve my love life?

All we can say is, you can offer people a lift. That gives you a chance to spend some time with them, build a little trust that you’re not a psycho, perhaps even tell them a few jokes. We conservatively estimate the increased hotness from riding a Boda Boda Cargo Cruiser to be in the 18-22% range and a Mundo in the 17-23% range, which is more of a margin than many recent presidents have been elected by. So, the answer is…a qualified yes. Provided you’re not a psycho.

Do Yubas fit in bike lockers at public transit stops?

Based on information provide for us by the BART agency, Mundos will not fit in bike lockers. It would be possible to get a Boda Boda in a bike locker, if the handlebars were swapped for a narrower bar.

Do Yubas fit on the bike rack on the public bus or Amtrak?

Yes and no. The Boda Boda can fit onto most public transit bike racks. If it’s a tight fit, the front wheel can be rotated 180 degrees to shorten the wheelbase by 4″ more.  The Boda Boda also fits onto the Amtrak bike racks.

Unfortunately, the Yuba Mundo with its 59″ wheelbase, is generally too long to fit on to bus bike racks. Amtrak also has prohibitions against bringing longer bikes, such as tandems, recumbent and longtails on to American trains.

Fortunately, commuter subway and ferry systems generally don’t have prohibitions against longer bikes. Remember that you can flip you Mundo up on it’s rear wheel and Sideloaders to get it on elevators to get you down to the platform.

Do you have any resources for carrying bulky or unusual items on your bikes?

In general, if you want to do a custom build, it is best to work with someone who has done that build before or with someone who is very familiar with our bikes. Your local bike shop may be the right answer, or you may need to look further afield. For those of you who are handy, head over to our blog  WhataBikeCanDo and have a look at some of the ideas folks have submitted to us. There’s a trailer for a Boda Boda, a write-up on how to transport multiple bikes on a Mundo, a fat Mundo and more… Many more riders have built and posted their methods and contraptions on their own sites all over the internet. A quick web search is sure to turn up dozens of wildly creative ideas!

If you’re looking to get a pedal powered stage, you can contact Rock the Bike in Berkeley, CA. They have built numerous stages for people, and have also done many custom configurations.

Folks use their Yubas in all manner of ways!

Can I use your bikes to get my board / kayak / SUP to the waves?

One of our favorite ways to use the Boda Boda or the Mundo here at Yuba is to carry a SUP (stand-up paddleboard). We have carried wave boards (8.5″ long) and race boards  (14″ long). We have also hauled whitewater kayaks, and even sea kayaks! It is easy and simple to use the Boda Boda and the Mundo to transport long loads. Both bikes feature side loading platform. The board or craft is positioned lengthwise on the bike. In general it is best to position the board on the right side of the bicycle. A couple of pieces of high-density foam positioned along side the rack create the necessary clearance for the biker’s feet. With some crafts such as a whitewater kayaks it doesn’t even require to use a block of foam. Yuba Bicycles will be releasing a SUP/ Surf/ Kayak pad system during the summer. In the meantime, visit our blog for instructions to help you make your own.

How much can I really carry on your bikes?

Our bikes are built with integrated frames and racks, making their carrying capacity virtually limitless. The Mundo’s Sideloaders and the Boda’s Lovehandles make it possible to carry ungainly things, from wooden pallets to kayaks and stand up paddle boards; from kids to unholy quantities of fruit!

Boda Boda:

The Boda Boda is rated for 220 pounds (100 kilos) of cargo – plus rider. This roughly equates into one adult passenger; 40 watermelons; 2 pony kegs and a kid, or whatever you want within reason! Its eight speed drivetrain with MegaRange makes it pretty easy to get up, down and around with your all your gear.


The Mundo can carry 440 pounds (200 kilos), plus the rider. That is approximately two adults; 1723 bananas; two full sized kegs and a drinking buddy, or whatever your legs can pedal. If you are planning to use the bike to transport bags of rice or concrete, it is probable that you will give out before your Mundo does. The rigidity of the frame makes it a great bike for heavier cyclists as well, because they do not have to concern themselves with frame flex, or stress-fracturing the frame. The Mundo’s 21 speed drive train with a front Granny gear and a rear MegaRange make it easy to get your stuff where you’re going (even way up that hill)!

I have a couple kids, which bike is better for me?

The best way to figure out which bike is best for you, is to go to your local Yuba Dealer, and try out the bikes. As a general rule, if you’re hauling 1 kid and a small amount of stuff (2 backpacks and 2 bags of groceries) all the time, the Boda Boda should be perfect. That being said, you can fit two kids on the Boda Boda if you want.

If you have 2-4 children, the Mundo is probably the better option. The rear rack can comfortably sit up to four children, and with that amount of weight, you’re going to be glad to have the 21 gear drive train. As a dedicated “school bus” for a larger family, options such as the Towing Tray, and the ultra-large Go-Getter bags make it easy to get all the kids, their lunches, science projects, backpacks and musical instruments to and from school.

Where is my Yuba’s serial number located?


Your Mundo’s serial number is located on the kickstand plate, just behind the seatpost and is visible from above.

The Mundo V4 number will begin with “ACA…”; The Mundo V3 number will begin with  “AD…”; Mundos V1 + V2 do not have a serial number.

Boda Boda:

The serial number of your Boda Boda (or elBoda Boda) can be found under your bike stamped into the bottom bracket shell between the pedals.

I’m really short/tall. Will your bikes fit me?

We design the Yuba brand of bicycles to fit as many people as possible.


Generally speaking, the Yuba Mundo fits riders from  5’0” to 6’7”. Any shorter, and you need to ride in the Yepp Maxi! There are some stem extenders on the market that our taller customers have recommended. Please contact us for details if you are taller than recommended.

Boda Boda:

To accommodate a wider range of riders, the Boda Boda comes in two sizes: a step-thru medium size (fits riders 4’9? to 5’10? or 150cm to 177cm) and a step-over large size (fits riders 5’5? to 6’6? or 167cm to 202cm).

What makes Yuba’s bikes special?

Yuba bicycles and add-ons are designed for everyday trips by ordinary people. We make bikes that help people live healthy and full lives without needing a car for their transportation. Picking up kids from school, dropping off 50 pounds of apples for a friend, giving a date a lift; this is what our bikes live for!

All of our bikes feature integrated racks and side-loaders giving them unusually high hauling capacity and unsurpassed stability under load. This means that even with two kids and this week’s groceries they ride like, well….a bike!

We spend a lot of time thinking about cargo. Our selection of Add-Ons are specifically designed to help you configure the bike to your specific lifestyle. For children, our accessories are designed to grow as the child grows. From the Yepp Maxi, to our Hold On Bars, Soft Spots and beyond; our Add-Ons will accommodate the needs of your growing family.

Kids are more than just cargo on a bike; they’re a loveable load that wriggles and interacts with the world. Yuba bikes are built to be stable and feel safe when carrying kids. With our integrated racks and one piece frames, our bikes do not flex when kids are riding shotgun. The stiffness of the frame translates into an extremely stable ride, even when your ‘cargo’ starts singing “The Wheels on the Bus Go Round and Round” at the top of their lungs!

The Mundo’s “wings” or Sideloaders and the Boda Boda’s Lovehandles are sturdy loading platforms to carry objects best supported from below. With the wings as a horizontal platform and the frame as a vertical support, very large objects can be securely strapped to your Yuba’s frame. In our opinion, this design is superior to front platforms or buckets because the Sideloaders can carry any sized object that can be strapped to them. Pick it up, secure it, and away you go!


What version is my Yuba Mundo?

Over the years the Yuba Mundo has gone through many changes, the most noticeable of these happening to the rear rack. Here are the different Yuba Mundos and the major changes to their frames:

-V1: Our initial offering was manufactured in Germany and has a bolt-on rear rack, the most notable feature of which is the “W” shape of the rear rack stays. Also, the top and down tubes on the front triangle have a circular cross-section rather than oval.

-V2: This version was also manufactured in Germany and had a bolt-on rear rack. You’ll notice that the rear rack has been redesigned and the front pair of the stays have been replaced by a single vertical unit. This bike’s top and down tubes are ovalized, and a kickstand plate was added.

-V3: For this version, we moved production to China and made several changes to the frame. The rack stays are in the same configuration as the V2, but the rear rack is now welded to the frame. We included for the first time the many braze-on mounting points on the rack and sideloaders along with disc-brake tabs and a 21-speed drivetrain.





-V4: The V4 shed unnecessary weight while maintaining strength and integrity . The rear rack has been redesigned with only 3 rack stays per side and has 22 braze-on mounting points throughout the deck, rack stays and sideloaders. Disc-brake tabs have been retained as well as the ovalized top and down tubes. It is also our most completely outfitted bike to date featuring fenders, a dual-leg center stand and a bamboo rear deck in addition to the 21-speed drivetrain. All models from V4.2 forward have a cromoly front fork with a threadless headset.

-V5: You asked and we answered! We’ve updated our popular Mundo frame with many features riders have requested over the years. The frame is now constructed with 4130 Cro-Moly steel and provides a weight savings of 6 lbs while remaining just as strong as its predecessor. The steer tube diameter has increased from 1-1/8″ to 1-1/2″ to increase front end stability. Another addition to the frame are the lock tabs that accept our Frame Lock to help secure your bike for short stops. The rear dropouts have been changed from horizontal 14mm pieces to vertical 10mm so standard rear wheels may be fitted.  Each V5 is equipped with hydraulic disc brakes and we’ve removed the cantilever brake bosses to clean up the fork. We’ve upgraded all components as well and a complete list can be found on our Sizing and Spec Sheet.
