Using the Cycle Analyst with the elMundo Cargo Bike

Cycle Analyst info

Voltage, Power, Speed - Screen 1

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?

Setting up the Cycle Analyst

Hold-on left button to set-up

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

Enjoy, Matt!

Matthew, a happy new Mundo owner

I sold my bike today.  Well, it’s wasn’t really my bike.  It belonged to Yuba.  But in my mind, it was my bike.  If you’ve been cruising our web site or seen our ads, chances are you’ve seen this bike.  Funny thing is I didn’t think I was attached to it until I saw it roll away and suddenly it hit me.  Damn.  That baby and I have been through some real adventures together over the last year.  It was my daily commuter to Yuba HQ in Sausalito.  But it was also the Yuba demo bike that went with me to nearly every sales call and new town that Yuba visited over the last year.  Some people put hundreds of miles on their bikes and never leave their community.  My bike and I have covered hundreds of miles through dozens of different towns and cities all over the country.  Each ride was a wonderful adventure of exploration and discovery and really good memories – from Portland to Los Angeles, from Santa Cruz to Madison.

She and I parted ways in Flower Mound, Texas of all places.  That’s near Dallas where the dawn is really starting to break on utility bicycling.  Matthew is her new owner.  He’s from Plano, Texas.  Matthew is committed to reducing his carbon footprint by commuting to work exclusively via Mundo.  Those of you up north know the commitment it is to commute by bike all winter. Down here it’s the summers that’ll get ya.  We’re all behind you, Matt.  He’s also thinking of adding electric drive to make his new Mundo.  I hope we hear more from him on this blog and facebook.  Well, have fun, Matthew.  I wish you both many fun adventures.  Don’t forget to post!

Hmm, there’s still enough daylight left for me to pull a new Mundo out of the box and get her ready for tomorrow’s adventure in…um…Oak Cliff!  Let’s see.  Orange.  How perfect!


The Bicycle Works in Marin County Selling More Electric Mundos

The Bicycle Works is Marin County’s first non-profit bicycle co-op.  Directors Jelani Bertoni and Spokey Godfrey, vialis 40mg have launched this project in San Anselmo to inspire people to live more active, view sustainable lives.  This amazing do-it-yourself bicycle workshop offers the community a place for people to get bicycle knowledge and skills so that everyone can use a bike for their everyday transportation.  They have a passion for getting people out of their cars and on their bikes.  Part of that passion is their realization that many more people will get out of their cars if they can have an electric-assist bike.  The Bicycle Works is a laboratory for electric bike testing and development.  If you stop by their shop in San Anselmo they would be happy to show you their electric Mundo.  Come see what an electric Mundo can do for you!
