Stick on Garmin adapter?

[kingrollo]

My e bike from decathlon comes with a BC900 computer - which attaches right out front of the stem. The BC900 has one useful data field - but it's the all important battery life !!!

Anyway I'd rather my wahoo + cycliq camera light take prime position on the bars and I want to relegate the bc900 to the stem.

I wonder if there is something I could stick to BC900 so I can slot it into a Garmin stem mount ?

You can get kits that do exactly that - such as this one https://www.amazon.co.uk/NELboNs-Computer-Adapter-Compatible-Replacement/dp/B0BG7Z3MGM.

Brilliant - that one seems to get decent feedback.Thank you.

You might be able to connect your Wahoo to your ebike and have the data on one screen. My Wahoo connects to di2 and provides all the info I need and more. Importantly it flashes up a red warning level when battery levels reach a critical point.

You can get stick on adapters for phones and i wonder if it would work as the decathlon unit looks like it has a flat back ?
i have used something like these in the past when using a phone with zwift .

I get some data on wahoo. But not battery life. Garmin seems better in this respect.....but I've only recently switched to wahoo !!!

I'd be surprised if ebike battery capacity is simply not available on a Wahoo device. It's such a basic requirement.
Maybe there's an addon field available. Does Wahoo have the equivalent of Garmin's Connect IQ store?

Don't know if this gives you enough info but are you aware of the iWoc LED colour coding? From memory it's white >75%, green 50-75%, amber 25-50% and red 10-25%. Under 10% is flashing red and gives much reduced assist.

Do this search on Google and you'll find the way to add your BC900 to a Wahoo.

At the risk of repeating myself. Wahoo doesn't display the e bike battery level. Even wahoo themselves say this. I believe it shows on some garmins - but even then the accuracy seems sketchy.

Problem with the iwoc controller is that it uses colour coding to display the level of assistance as well as battery life. It's early days but I haven't got my head around assistance level v battery life from the lights.

Forgive me if I am overlooking something. But even if the above is possible - I'm still going to need the BC900 computer somewhere on the bike ????

I wouldn't have thought so but you can only be sure through testing this.

I don't see how I can pair a sensor (BC900) - if this device isn't switched on and in some proximity to the bike ?

From what I understand the BC 900 is a GPS enabled device (computer/cyclometer) which records ride data. It doesn't appear to offer any navigation features. The BC 900 is the device which displays the information to you, this is not the sensor which provides the information. Your bike, you haven't said what it is, should/will have a sensor that reads the battery charge level and can transmit this information to a device that will display it. Provide the device can receive and display the information it doesn't matter if you use a Wahoo, Garmin, BC 900 or any other cycle computer.

My Kinesis runs Shimano di2. There are three batteries, one for the derailleur and one each for the shifters. Each of these transmits the battery level which I can read on my Wahoo or in the Shimano app. It doesn't matter which device I choose to use. The Wahoo is my preference as it's a far superior device and I can choose to see the battery levels while riding and receive a warning when they reach a critical level.

This is what I have set up on my Wahoo - it isn't connected to the bike at present.

GEAR BATT = the main derailleur battery
BATT% = the Wahoo battery level
SHFTR BATT = the shifter batteries - left and right display when the bike is connected
GEAR NUM - is the current gear in use

I hope this helps.

The bike is a decathlon edr af equipped with SRAM apex shifting. The SRAM gears are picked up by wahoo.
The motor is a mahle X35 - widely used by Ribble as well. Looking at Ribble forums getting the battery level to display isn't as straightforward as you suggest. The Mahle app and the BC900 seem the only way to get accurate battery info.
I did try pairing all available sensors - and one for the BC900 didn't show.

I will check again later - but I'm not hopeful. The guy in the decathlon store couldn't get it to show either

I'm sorry if I'm giving you the wrong impression. I haven't said it's simple but that it should be possible. I would say I have yet to find anything that is difficult to achieve on a Wahoo. A quick Google for "display mahle x35 battery level on wahoo elemnt" delivers the instructions below. The same Google search showed me a Facebook page where Ribble users are discussing how they can view e-battery levels on their Garmins. This is a very basic function when using an e-bike. I'd be surprised if a Wahoo doesn't offer the feature.

I've done my best. Good luck.

Steps to Display Mahle X35 Battery on Wahoo Elemnt

1. 1. Pair your E-Bike:
   • On your Wahoo ELEMNT app, go to Settings > Sensors.
     
     
   • Turn on your Mahle X35 e-bike and make sure your Elemnt is on and the bike is in Bluetooth range.
   • Look for a new sensor named "E-BIKE" in the Unsaved Sensors list and select it to pair. You might be asked for a PIN code found on the bike's TCU controller.
     
2. 2. Add the Battery Data Field:
   • In the ELEMNT App, navigate to Settings > Pages.
     
     
   • Select the page where you want to add the data.
     
     
   • Select Data Field and scroll down to the E-Bike or Power section.
     
     
   • Choose the "E-Bike Battery" option to add it to your screen.
     
3. 3. Check the Battery Level:
   • The Elemnt device will now display the e-bike's battery percentage directly on your chosen data screen.
     
     
   • You can also check the battery level on the Mahle iWoc controller on your bike's frame, where a colored LED will show the approximate charge (White for 75%+, Green for 50-75%, Amber for 25-50%, Red for <25%, and flashing Red for <15% or <10%).
