Arstu, I am here to give advice. I dont get paid to sit on the forum, I choose to help others out of my own time.
It appears that different manufacturers have been using different mechanisms. In my experience I have seen both 'Abus' and 'Trelock' lock mechanicms on different bikes. Who knows maybe KTM use a different one all together.. Its clear that the older KTM's (Yours & Ians) do seem to use a different lock. But you cant relate this to every bike and infact the newer Active / Performance lines which use different mouldings all together.
Yes on my large range of Bosch eBikes (from varied manufacturers) the battery has always been able to be inserted without the use of the key.
Yours sounds like it does not, so you require the key to re insert, no biggie, just use the key.
Saying things like -
This is unfair... We would not look to abuse anything, we are here to help. In most situations its the other way round, users have abused the system and we have to clear up the mess.
Just to sum this thread up - All of mine can be re inserted without the use of the key. As many other have stated here. But some dont..
Lets keep the focus of the forum a nice place to be and continue to help, guide and assit others.
The original post of this thread has been answered, so lets leave it there
Happy eBiking
