Hello IanV! As Stefan Mikes said, this is likely an illusion. Due to the nature of the drive unit's integration into the bicycle, it is impossible for it to cause drag while coasting. A DU can definitely create some pedaling drag, as with the Bosch Gen2, but the DU has no way to apply any sort...

This is a great question. I agree- compatibility information, even without a list of actual 3rd-party devices, should be easier to find from Bosch. I appreciate the feedback, we will use this in our continued effort to improve. I've attached an unofficial chart below that one of my colleagues...

Hi @chromatose , I just spoke with Bosch Tech Support in Canada- they could not find any information on your case. Are you able to direct message Stephen or myself with information about your warranty case so that we can check on it for you? It may be a good idea to contact your dealer and...

Hello! My apologies for the difficulty with compatibility information here. I promise- Bosch is not trying to make anything difficult for anyone. We are able to publish the compatibility specs for connecting 3rd-party devices to Bosch products, but we are not able to supply a chart for actual...

@chromatose I recommend you stop riding this bike immediately until a qualified bicycle dealer has fixed the issue. Your video shows an extremely loose crank arm (the interface between the crank arm and the ISIS splines on the DU spindle.) It is extremely dangerous to ride a bicycle in this...

I'm not positive, but I think the BMW-branded Bosch-equipped eBikes were a model year 2016 product? If it has not had a software update since new, it could experience issues like you are describing. On the mechanical side, this sounds like it could be a faulty battery cable. Sometimes batt...

Hello @evosam, and congrats on the new bike! Custom values should default to the factory values, from what I've seen. eMTB mode is removed from the equation though, and replaced with standard Sport mode for custom riding mode purposes. There is no way to use eMTB mode with custom modes...

@Sparky731 A few notes on range, some of which you may already be aware of: - Range is calculated using approximately the last 1.5 miles of riding. - Range calculation will vary based on what assistance mode you currently have selected. - Range calculation may be heavily influenced by multiple...

Not sure which YouTube video you saw, but a swap from Purion to Nyon will require running the new cables from handlebars to drive unit. The Kiox to Nyon swap just requires (1-2) screws removed on the back of each mount, and the (2) cables switched over onto the new mount. After the physical...

Good question, and I'm not sure. @Stephen - Bosch Team might have a better answer, otherwise I can try to test it later this week.

I'm sorry to hear none of this worked. If I'm understanding correctly, your dealer contacted Bosch and has a warranty SPH on the way for you?

So far, nothing solid. These types of issues are difficult to diagnose from afar. Visiting your local Certified Bosch dealer is not an option? [updated] Please try: - charging SPH with an external charger (micro USB cable) for approx. 2 hours - Opening Cobi app on phone, "forgetting"...

I'm looking into this with our team. I'll get back ASAP once I have more info.

On all Bosch systems, your dealer can adjust the cosmetic speed readout by +/- 5% in the Diagnostic Tool. Some displays (Nyon, Kiox, SPH) allow the user to adjust the cosmetic speed readout using the display itself. If you think your speed is significantly off, you can ask your dealer to check...

The Purion is very accurate, assuming a very accurate circumference value programmed in the DU, but there are so many factors that will cause small discrepancies. The DU controls max speed, not the display. The display just shows what the DU is "thinking." In reality, everyone's effective...

My apologies, but this is inaccurate. The Performance Line Cruise DU does offer up to 65 Nm of torque, but is not included in the 85 Nm update as it is a Gen3 DU design. The 85 Nm software update only applies to some Gen4 DUs, depending on region. Again, sorry for any confusion. As a...

Very interesting. I'll ask the rest of my team if they've heard of anything like this. I understand the want for everything to be right- that's how I feel when I buy something. The good news is that I think this is likely just a software-based cosmetic hiccup. I'll get back to you once I've...

I'm not sure if Cobi sends a reminder, but I don't think it does. The software update may not solve it, but it's the first thing to check when experiencing minor issues such as battery % readout.

Congrats on the new bike! This is likely not an issue with your battery, but an issue with the way the software in your display is displaying battery charge level. I believe you have the Smartphonehub on your Allant? Have you used your Cobi app to perform a software update on the SPH hub...

Based on the information you've shared, @Andrew Edwards, this sounds like it may be a faulty battery cable. A few possible symptoms of a faulty battery cable are: - no connection to DU or DU/battery shown in Bosch Diagnostic Tool - Speed read-out on screen is blank (not even 0.0) - Intermittent...
