PS This was the reply from Gearsensor.com

Aaaaanyway. Thanks for all the replies. Clearly all well meaning and obviously taking time to help someone. Cheers. :thumb:

"The FAQ on the Specialized website might imply that they don't. They state: Shift the gears earlier than you would on a traditional bike. Ease up on pedalling power when shifting. If they had a shift sensor to cut power, then easing up shouldn't be necessary." Quite. Obviously...

" The best people to ask this of would really be the company (Specialized) themselves, for the specific model bike you want to get (because they might not have the same features on every model...)." I called Specialized, but found myself in a wearingly long conversation which I ended unsure if...

"Climbing too steep of hill in too tall a gear" Exactly. So I don't think ahead enough, or get taken by surprise by how steep it is. And then the motor bogs. So for a clueless and / or inattentive rider the nuvinci is a godsend.

Regarding the Bafang gear sensor, yes. That solves the shifting problem very nicely for powering along on the flat. But as I said, my experience was that when the motor cut for a moment, it did not resume with full power for too long, leaving the bike to slow on a steep hill. Perhaps this is a...

I guess I really should have given more description, but I thought the question was clear enough. I like the BMW a lot but it is a diamond frame. I need a step through. The only bike I have found with the 90nm Brose motor and a step through frame is a Specialized. Specialized do their own...

Thanks for the info about gearsensor.com. Out of interest I have emailed them to ask about how this would work.

I have a gear sensor off a bafang. But there is no way I am taking my wiring apart! I am not planning to modify the BMW. Plus I always found the use of the gear sensor on the bafang to be useless. Yes, it helps you to not fry your gears and chain. But the motor takes far too long to recover...

As stated in original post it is a BMW ebike. There is no accessible wiring.

Thanks, but this is exactly what I am curious about. Is the shift sensing a hardware property or can it / is it implemented in firmware? I would be fascinated if anyone can point me to an article on how Bosch or some manufacturer make this work.

I have a BMW with a Brose motor. There is no momentary lift off of power when I change gear. So lots of crashing from the gears unless I lift of pedalling as I shift gear. I have contacted experts and yes, this is not a fault, the motor just does not have this functionality. This is a big...

Hi Increasing RSI from using bafang plus and minus switches on the handlebar gizmo. Would love to be using the TSDZ2 XH-18 display which has the twist grip for plus and minus. Can anyone point me to a way to adapt it please. Or any other way of using a twist grip for that functionality. Thanks.

Golden motor MP4 kit is a sine wave which is generally held to be better and quieter. Incidentally, I rode a Giant Express, only a little motor, but geared, and it was totally silent under power.

Many thanks everyone. All useful info. I have a decent battery. 20 amp. I will go with the standard kind of hub motor. This seems like good advice too from the thread in the link: "... buying from a volume seller within the country you live to be the cheapest option because they buy in bulk...
