Thank you very much!Is this what you are referring to? This picture of my Allant has the rail installed but the battery is not on the rail.
On my Allant, the extra battery does not have a separate lock cylinder. It locks via the main battery (to remove the separate battery, you have to unlock the main or powertube battery) - so yes, it uses only one key.
On my R&M that is dual battery. Each battery has its own lock cylinder but they use the same key. On my Tern GSD which is also dual battery, they have separate locking cylinders and came with different keys - I had the cylinders changed to a keyed-alike setup. Neither of those bikes I believe are considered as having the Bosch range extender (are rather just dual battery) therefore I think you are referring to the setup on the Allant.
Thank you very much!
You have answered exactly what I want to hear!
As you said, I wanted to see what was attached to Allant.
The photos are also perfect.
I understand your explanation of using the built-in battery as a key.
I want to ask another question, what does it mean to change the cylinder to a key setting?
I know Tern GSD itself.
Sorry for talking unrelated.
I just purchased a Trek Allant 7+ S and had the Range Boost system put on as well. However, the dealer (installed) nor I can remove the Power Pack. They are thinking it's not removable. No way this is permanent. Over50, how did you remove yours?? There is no proprietary key to unlock it other than the RIB key as this doesn't tie into that lock system since it's an aftermarket accessory. And the "button" shown in the picture does not depress. We pulled, pushed, and pressed everything but it won't disconnect. Without damaging it, not sure I can remove this. I've contacted Trek and they say it should have a key and don't know why it's not disengaging. Any help PLEASE!!!
Yeah it doesn’t do anything regardless if the main battery is removed or still in place. I saw that the RIB should be removed in manual. I’m not seeing how this rail system connects in anyway to the tube battery. Can you take close up photos please? I’ll take video and see if that will post on my end.
