You can definitely return to Sport mode... shop would perform another software update, and select the "Sport Mode" container file, rather than the "eMTB Mode" container file. I may or may not do this on my pavement bike... can't decide if I like eMTB or Sport better for paved cruising. You are...

Yes, it replaces Sport mode. eMTB mode is less about hills specifically, and more about adapting to varied terrain. I sometimes use it when cruising around my neighborhood. When soft-pedaling... it gives me minimal support. When I really need to move, or get clear of a car, etc... I can get on...

Ah yes! I forget that the Allant has the CX DU option. I was thinking only of the Performance Speed. Thank you! You are correct, should be an option on any CX unless the OEM specifically decides not to allow it.

FYI: I've added info to my previous post... #51 in this thread.

The sporadic speed display points to speed sensor issue, as was mentioned above. A 2021 Rail should have Trek's proprietary speed sensor and rotor-mounted magnet combo, so mis-alignment of the magnet is less likely here, though was a common issue in the past. Some of the other things you shared...

Happy to help! I hadn't really thought about eMTB reducing chain vibration, but I suppose that makes sense as it tends to require more rider torque input. That being said, I'm not sure how much it will affect it in practice. I'm also not positive that eMTB mode is an option on the Allant+...

Hi David, Congrats on the new bike! 🥳 Noises, vibration, etc., are quite difficult to diagnose remotely, as you might imagine. The best advice I can give is to take your bike back to the place of purchase, and get it looked at by their trained mechanic. Whether it's an issue with the eBike...

Great questions! I think the eMTB to Sport selection by the rider would be very popular, and would make sense to have. The difficulty though is that eMTB mode is part of one software package, and Sport mode is part of another. While both software packages or "Container Files" are essentially the...

The Bosch Powertube battery is not part of the frame structure in any way, and is not a factor in rigidity. In terms of covering an unused compartment, some OEMs design the battery cover to attach to the frame, independent of battery, while other OEMs attach the cover to the t-slots on the...

It is very easy to miss/lose. It is a tiny screw, and comes in a tiny plastic bag. In the attached image, it is the screw on the left, next to the square nut. Everything else pictured in this "spare parts" kit comes already installed on the Kiox mount.

Good call! I've been meaning to lock mine down too, but keep forgetting to find the screw. FYI for anyone considering doing this: If you are not using the locking screw that came with your Kiox, please make sure it does not apply any upwards pressure on the Kiox display itself. In the past...

There may be a place in the app to report, otherwise you are welcome to share them in the "feedback to Bosch" thread and I can pass them along.

Hello! Purion and Intuvia both use their own specific wiring, so any change to or from Purion or Intuvia will require running a new cable down to the drive unit. Kiox, Smartphonehube, and new Nyon all use the same wiring harness and remote, so any swapping between these (3) just requires the...

You are correct. Gen4 drive units do not have the small "clunk" feeling when you stop pedaling abruptly. This is because the mechanism that transmits power from the motor to the output shaft in the Gen4 DU design involves a ratchet mechanism that allows the chain ring to move forward without any...

First of all, that sounds like an awesome eBike you've dreamed up! :cool: The Bosch System is only designed to work with (2) batteries maximum. It's never worked for more than that, and I've heard of no future plans to move in that direction, unfortunately. I've occasionally considered the...

Apologies for the delay on batteries. Unfortunately, just about everything in the bicycle industry is facing major delays currently, as is the case with most other industries too from what I've heard. That being said, it sounds like the Bosch rep you spoke with on the phone may have been...

Based on some conversations I've had with the rest of my technical team, it appears your circumference was definitely programmed wrong during assembly. If you haven't already, I'd recommend a call to your local, Bosch Certified Dealer. They will be able to work with Trek to get this value...

Do you recall what the circumference value was set at from the factory, before you made the adjustment? I may have misunderstood something here, but in your first post you mentioned having a 27.5" tire. This more recent post calls out the 700 x 35 Schwalbe, which is consistent with Trek's...

The dealer can use the Bosch software to adjust the 5% "cosmetic" allowance if needed, but nothing more. If there is an issue and the factory-set circumference value needs to be changed, the dealer will have to do a remote diagnostic session with the OEM, where the dealer connects your eBike to...

I'm not sure what your wheel circumference is set at from the factory, but if the value you are attempting to use is more than 5% different, the system will not allow it. The constraint is there because the need to go beyond it likely indicates another issue, whether factory programming mishap...
