Brief Report of The First Two (Long) Days of Using Wahoo Elemnt Roam with Specialized Turbo Vado SL 4.0 and Vado 5.0
I wanted to write a long and detailed review. Unfortunately, I lost most of the text already written. Posting remnants here, the concise way.
tl;dr: Both Wahoo Elmnt Roam and Garmin Edge 830 are equal devices working on somewhat different principles, and both are capable to connect to Specialized and Giant e-bikes that support ANT+ protocol. I'm very happy with my Wahoo Elemnt Roam that I tested with both Vado SL 4.0 and Vado 5.0.
Foreword
Wahoo Elemnt Roam is a competitor to Garmin Edge GPS bike computers (it is a direct competitor to Garmin Edge 830). There are several features making it different from Garmin:
- Wahoo bike computer is solely button operated; and the buttons are large and practical, making it ideal for use during the cold season or rainfall; Garmin uses a touch screen.
- You configure the Wahoo almost entirely on your smartphone; with Garmin Edge, almost all configuration has to be done on the device;
- There are no external apps or data fields for the Wahoo: all functionality is in the device or on your smartphone;
- To get the max out of your Wahoo, it is better to carry your smartphone with you on your rides. (In the pocket or bag).
Compatibility
Wahoo confirms the Elemnt Roam is compatible with all Specialized Turbo e-bikes equipped with either the TCU controller or the TCD-w display; and with all ANT+ compatible Giant e-bikes (ones equipped with the RideControl One remote or newer ones). Multiple e-bikes can be served by the Elemnt Roam (one at a time).
The First Pancake Is Always Spoiled, or potential setup glitches of Wahoo Elemnt Roam
The setup of the Roam should be very easy. You start with installing the Elemnt companion app on your smartphone, creating your account for Wahoo, and pairing the device with the smartphone (which is an extremely easy process!) Here are issues I had with the initial setup of the Elemnt Roam:
Wi-Fi Connectivity
On the first use, the device tries to locate an available Wi-Fi network. It didn't work in my case. After I completed the initial setup, I could finally connect to my Wi-Fi. Transparently to me, the device downloaded software updates but I was not informed I should have restarted the Roam. As many things didn't work as expected, I restarted the device to see the Roam installing the updates only on the restart.
Pre-installed Maps
Wahoo has pre-installed as many maps as to leave no internal memory space to just
update your local maps! I solved that issue by deleting maps for regions I wouldn't visit in near future (think of Albania; or, for that matter, the United States: I can download the maps of the U.S. later when I will need them). Deleting unnecessary maps freed as much of the device memory as I could update the map of Poland.
Pairing E-bike with the Roam
Your Specialized, Giant, or another ANT+ compatible e-bike is seen by the Roam as a sensor (the same way as your heart rate monitor is seen by the Roam). The first pairing of my Vado SL only connected the Cadence and Power sensors of the e-bike. That was
wrong. Later, I deleted the sensor named E-Bike and paired my Vado SL again. Only that time, I could see the proper picture of fully connected e-bike in the Elemnt Companion App:
You need to see the Odometer status if the e-bike is properly detected as a full blown Sensor.
Note: I also paired my Polar OH-1 HR monitor with the Wahoo.
Configuration details
Wheel Circumference Is Critical!
As long as your e-bike has been connected to the device as a Sensor, you should verify the Wheel Circumference! Let me explain that, as the matter is not that simple.
- All your e-bike really meters is the number of revolutions of the rear wheel per minute;
- Your e-bike has the Wheel Circumference (WhC) value coded in the firmware by the factory or a dealer;
- The RPM multiplied by WhC gives the Distance ridden;
- The Distance ridden divided by Time gives Speed.
If -- by chance -- the value of WhC coded inside your bike is proper then no worries. However, changing your tyres to another size (or even riding at different inflation pressure than expected) will dramatically and badly affect the values reported by the e-bike. (It also can happen the coded WhC value is simply wrong!)
Now: Elemnt Roam will always report Speed as reported by your e-bike; you cannot change that behaviour. However, what really matters is the correct Distance ridden. And you can modify the Wheel Circumference value in the ELEMNT Companion App.
Elemnt Roam will read the Wheel Circumference value off your e-bike (it is 2180 mm for my Vado SL 4.0 and 2255 mm for my S-Vado 5/6). You are free to type any value instead here.
Let me give you an example: My Vado has the WhC value coded as 2255 mm, and that is for stock 29x2" Specialized Electrak 2.0 tyres. However, I swapped the stock tyres for 47-622 (28 x 1.75") Schwalbe Smart Sam. Consequences:
- The Speed reported is (and will be) always too high (it depends on the WhC value stored in the bike)
- The Distance reported will be correct only if I change the WhC to 2220 mm in ELEMNT Roam Companion (connected to the device, and the latter to the e-bike).
(Similarly, I'm experimenting to find the proper WhC value for my Vado SL with new 37-622 tyres).
E-Bike Data Fields
As long as your e-bike has been
properly identified as a Sensor, there is pretty a lot of information extracted from the bike. For instance Speed, Cadence, Rider's Power, Assistance Mode, Battery % or Range are taken from the e-bike. There are three e-bike specific fields available:
- LEV Battery: Your current battery %. It is not to be confused with Battery (which is the device battery %) or with Phone Battery %;
- LEV Travel Mode: It is OFF, ECO, SPORT/TRAIL, TURBO, SMART (Or ECO or BASIC or ACTIVE etc. for Giant e-bikes)
- LEV Range: The Range is not given by Specialized e-bikes but it is given by Giant ones.
("LEV" is for Light Electric Vehicle).
Here is an example how a well configured Workout Data page might look like:
Up to 11 data fields can be selected to the Workout Data. My selection was: Speed, Distance, Ride Time, Clock, Travel Mode, Bike Battery %, Distance to the Route Destination, Cadence, Rider's Power (average for last 3 seconds), Heart Rate, Device Battery %.
There is an interesting (Wahoo specific) way to limit the number of fields visible, and to increase the font size: just operate the Up and Down buttons. As the font increases, the less important data fields are removed from the view. That's why you are expected to not only select the desired data fields in the Companion App but also sort them from the most to the least important to you.
Data Pages
There can be maximum as many as four flippable data pages:
- Lap Data
- Workout Data
- Climbing
- Map (GPS Navigation/Routes)
- Strava Live Segments
- KICKR control
- Planned workouts
These screens are configurable by the user.
I have found it practical to limit the number of Data Pages to just two: Workout Data and GPS Navigation. (I will only turn the Climbing screen on when I go for mountain trips). Having just two Data Pages makes it very easy to flip them on the ride.
Necessary to mention, the interaction between the pages is automatic. For example, you might stay in the Workout Data but you will get turn-by-turn indications when you're approaching a turn. Or, the Climbing page would pop up if you approached a climb.
All you need to do to flip the pages is to hit the large right button at the device bottom.
Connectivity to Sports Online Services
That's a breeze! The easiest thing to do. Let's say, I use a free RideWithGPS service for route planning but I'm a Strava subscriber for my workout tracking. You just need to authorize the Element Roam to use both services. Synchronization of planned routes is automatic! Just create your route in RWGPS, hit "Send to device" and your route is in the Roam! After you have completed your ride, your ride data are synchronized to both RWGPS and Strava as long as your smartphone is connected to the device (and it has an internet connection).
More Sports Online Services are available, too.
Ride Impressions
Just fantastic!
- All ride, rider and bike data are clearly visible to you, as if you had an advanced display
- Should you navigate, flip to the GPS Navigation page, or just watch the turn-by-turn indications in the Workout Data
There is an advanced system of LEDs at the left and top edge of the ELMNT Roam. The vertical row can, for instance, show your speed relative to the current average (faster, much faster, slower, much slower, at the average). Or, that might refer to your leg power. Or, to your heart rate.
The top row of LEDs visually indicates a turn to be taken. It is also for notifications.
There are so many navigation modes! The two most useful are:
- Get Me Started: No navigation. Just press the button indicated as Start and ride. You get the Workout Data displayed and recorded
- Turn-by-Turn: Activate a route and ride with GPS navigation
I won't describe all the modes: There are too many of them, and that's what you could expect from a premium GPS e-bike navigation!
Live Track
You can share your ride with family or friends: It works exactly as Strava Beacon.
Post ride report
You will get all vital ride stats. Very important information is how much of e-bike battery you used for the ride.
Recovering the real estate on your handlebars
Regarding Vado SL, I got rid of the smartphone and the TCD display from the bars:
Clean & sleek
I
could get rid of the smartphone from the bars. The display of the "big" Vado is mandatory, though.
Specialized Display Mount and Wahoo
The Specialized Display Mount is for Garmin. If you want to re-use it, Wahoo comes with an inexpensive Garmin adapter:
The Wahoo ELEMNT Roam comes with a rock-solid dedicated out-front mount (I used it on my full-power Vado) and with a stem mount to be installed with provided zip-ties.
Wahoo and KICKR
ELEMNT Roam is a must if you use the Wahoo KICKR indoor cycling trainer.
Final Warning
Neither Wahoo ELEMNT Roam nor Garmin Edge 830 are for people with bad eyesight
These displays are too small!
