Kristin Rule, aka, ‘The Unconventional Cellist’, and Andy ‘Mechanarchy’, completed a 1,000k Bicycle Tour of Tasmania in December 2011 and January 2012. They rode Yuba Mundo V4′s (23kg), each ported 45-50kg of extra weight, and they were assisted up the crazy Tassie hills via Andy’s custom built Solar Electric Assist bicycle trailers.
Title track is ‘The Awakening’ (original live looping piece by Kristin Rule). Recorded Live in performance at the Cygnet Folk Festival 2012 (using Ableton Live & Softstep).
The Cycle Analyst (made by Grin Technology in Canada) is the unit that can be seen on the handle bar of the elMundo Electric Cargo Bike. The Cycle Analyst is the bicycle onboard computer; it is connected to the battery, the controller and the odometer. With the Cycle Analyst the e-bike rider can then have a sense for:
• the speed in km/h or miles/ hour.
• the power used by the e-bike in Watts.
• the electric potential in Volt.
• the current in Ampere.
• the electric charge in Amp/hour.
Prior to using the Cycle Analyst and in order to really take full advantage of it, it is essential to learn:
º to read the screen and the data provided.
º to reset the unit after having charged the battery.
º to parameter the CA properly, this includes (wheel size, shunt resistance, unit…).
The complete Cycle Analyst manual can be downloaded here.
A) How to parameter the CA?
The first thing to do when receiving/ installing the Cycle Analyst is to set it up properly. If this is not done prior to riding the bike, all data read on the Cycle Analyst unit might be wrong.
Step 1: Hold the left button for 2 seconds and then toggle on the right button to the various screen.
Step 2: Set the essential parameters:
• wheelsize (2065mm for the elMundo)
• unit (km/h or m/h)
• RShunt (specific to each controller)
• number of poles (see manual for details -> should be 1)
B) What’s on the screen and what it means?
The Cycle Analyst shows multiple screens:
# 1 the V,W,A,Ah screen.
# 2 the V,W,A, Km/h screen.
# 3 the Total W/hrs used by the bike over time.
# 4 min, max Amp screen
# 5 the screen resuming the # of cycles
The screen 1& 2 are the most important one. You will see Voltage (V), the Power(W), Current (A) used and most importantly the consumption of current per hour (Ah). This last indication is critical since it displays how much current is left in the battery. In the picture on the left it reads 2.814Ah, assuming that the elMundo Electric Cargo Bike is using a 37V 10Ah battery, it means that there’s 7.186 Amp to be drawn from the battery. In other words when the reading gets close to 8.5 A/h, you will be running out of battery soon! So charge it! But every time your recharged the battery (fully) you need to reset the cycle analyst to 0! In order to this hold the right button for 1 second.
* if you had a 14Ah battery, the battery would run out close to 13-14Ah

Want the stability and handling of the Yuba Mundo and the power of the StokeMonkey? The eBike Store of Portland is now shipping Mundos equipped with StokeMonkey electric motor kits. Want to build your own? The eBike store is also manufacturing and shipping the StokeMonkey Adapter Kit designed specifically for the Mundo.
Yuba Bicycles already offers an electric-assist version of the Mundo called elMundo as well as an electric upgrade kit for the Mundo. ElMundo is a front-hub motor system based on the eZee electric motor kit. The StokeMonkey Mundo is an alternative for riders that prefer the additional hill-climbing power of the popular, mid-drive StokeMonkey electric motor system.
Yuba Bicycles’ mission has always been to get people to use their bikes for everyday errands instead of their cars. Electric-assist systems enable the Mundo to go further distances in steeper terrains. The result is people will use their bicycles to make trips that they would normally make in their car, turning car-trips into bike-trips. Yuba is jazzed that they can offer riders multiple electric-assist solutions depending on their preferences. Whichever system you use, adding electric-assist perfectly complements the Mundo’s load-carrying capabilities and confidence-inspiring handling characteristics, enabling riders to comfortably go further, faster. Whether you are carrying groceries, children, a cooler full of beers or all of the above, the Mundo is “What a Bicycle Can Do!”

We have reached an important juncture here at Yuba Bikes. And as I said, it’s electrifying… I refer here to the new Yuba/eZee elMundo hybrid-electric cargo bicycle, and my joining the Yuba team to lead the charge, so to speak.
We are very excited with this evolution of the Mundo and what it represents for our transportation choices. We all recognize the situation we find ourselves in as a Civilization, and one of the most profound choices we can make is around our modes of transport. The elMundo is a key component to our collective realignment toward thriving, efficient communities. Choosing to use a bicycle, perhaps with a hybrid drive system, is a very real vote for the Future. Please join us in casting this vote…
The elMundo, with its purpose built electric ready frame, is our latest effort at realizing a long term goal of providing the most robust, useful, and fun-to-ride cargo bicycles on the planet (yes, the whole thing!). The Mundo is a marvel of utility and laughter-inducing joy; so naturally, adding the phenomenal capabilities of the hybrid-electric drive system has made it nothing short of miraculous! And really, we could all use a few more Miracles in our lives…
As we move forward with the development of the Electric Division, look for an expanding resource library, complete with videos and an extensive how-to section. We want to demystify this simple-to-use and life-changing technology, making it easier for you to enjoy it and love it! Specifically, these resources will include technical support and data; instructions on how properly use and maintain the electrical components, with a very important section on battery care; techniques for riding safely with maximum enjoyment and efficiency; load dynamics and different options for expanding the utility of your elMundo; as well as real-world use data to help you understand the true capabilities of this marvelous machine…
I’m happy to be a part of the Yuba family, and look forward to working with the crew to further revolutionize personal transportation. Exciting times… And we may as well have fun while we change the world! Here’s to a future that includes healthy and resilient communities, with abundant bicycles and smiling neighbors…
After a few years of R&D, Yuba and eZee are proud to introduce the new Yuba/eZee elMundo Electric Cargo Bike.
