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!

Lighter *is* faster, but by a far, far smaller degree than widely supposed. Most of the work of pedaling a bike above speeds of about 12mph is overcoming wind resistance, not overcoming the inertia of the bike itself. Also, heavier bikes are notably slower to accelerate. It’s just that once they’re rolling, it’s not much more effort at all to keep them going.It’s funny that I don’t perceive the Mundo as being slower, except when it’s loaded up with a lot of cargo and I’m heading up hill. Quite the opposite. I guess this is just perceptual, since my previous bike only had one gear, and apparently a pokey one at that. The heavier Yuba Mundo is also slower to stop, and this jives with Newton’s laws of motion, too. I actually bought a louder bell (a nice brass Crane bell with a spring loaded clapper) on my bike last week because I was worried someone would walk out in front of me while the bike was loaded and I was zooming down a hill. It takes a good long while to stop, even with well adjusted disc brakes (which by the way, I would consider to be essential components of any cargo bike). Objects in motion like to stay in motion, indeed. I asked the same question of my friend and once college roomate Phil, who is now one of the world’s top experts on the subject of athletic power. He confirmed and expanded upon Todd’s explanation, and reading his response it began to feel a bit as if we were talking more about airplanes than bikes:
The takeaway is that the extra mass matters, sure, but not as much as one would think. Which is another way of saying that carrying your groceries home on your bike instead of your SUV is not as crazy an idea as you might think. Another conclusion I made form this inquiry is that I made a good decision in getting the Yuba Mundo. It’s extra length adds weight, sure, but doesn’t add anything (or not very much) to the aerodynamic cross section of the bike. Something like a bakfiets, with a wide honking cargo box on the front, is, to use Phil’s expression, punching a much bigger hole in the air. It’s funny, but now that I’ve been riding the Yuba back and forth to work every day, getting groceries with it, and of course, lugging my telescope around on it, I can’t believe I sat in a car for long and let an engine, and way too much fossilized dinosaur poop, do the work for me. It’s not much work at all, and the cost per mile is stronger legs and lungs. *The link is to an excellent RadioLab episode that features a story about the RAAM. RAAM’s official website is here.
1. Roughly 80% of the energy of pedaling a bike involves overcoming air resistance. Thus, under all conditions other than a strictly uphill climb, aerodynamic considerations vastly outweigh weight considerations.
2. The most important consideration with respect to how quick you will get up a hill is the power to weight ratio, i.e. how many watts can you generate versus how much mass you are moving up the hill. Very good riders (i.e. guys that contend for the Tour De France) generate maybe 5ish watts per kg body mass and can hold than for less than an hour. More pedestrian riders probably generate 2 watts per kg over a similar time frame. You make considerably more power than this in the metabolic sense, however, you are only about 20-25% efficient in terms of what actually gets delivered to the external environment. This is why you get hot when you exercise…the rest of the energy is liberated predominantly as heat.
3. The most important consideration with getting down a flat road is power versus frontal surface area. Hence the aerobars you see on time trial or triathlon bikes. You are trying to poke a smaller hole in the air.
Mundo: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).
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.
Mundo: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 Boda Boda number is stamped into the underside of the bottom bracket. The number will begin with “LY…” (insert picture)
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.
Mundo: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)!
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.
