Hi there new to the emtb scene and I got a my cube 160 2021 had the same issue.
ive now lost the battery cover. The shop I bought it from has zero aftercare which is annoying.Would you mind sharing where you got the cover and latch mechanism from?
Hi and welcome. Its annoying, isn't it? I got mine from where I bought the bike. Leisure Wheels, Hemel Hempstead. I think that you will have to go through an authorised Cube dealer as they have to order parts from Germany, which takes ages.
You need to get the right part number to start with. My bike is the 120 which is a different cover to the 140 and 160. If the 140 and 160 are the same , the part number is 18-05597, as mentioned above.
The latch mechanism is a separate part, which you will also have to order.
Try google as well. I found some third party parts in Romania, Slovakia, etc but nobody replied to emails.
You will have a wait of several weeks, so you will need to protect the battery in the meantime, as all the crap from the front wheel goes straight onto the battery area. I used a front mudguard [ the type that fits onto the downtube], cable ties, and some gorilla tape. it doesn't look great , but keeps the crap out.
I think the first step is making sure that you are ordering the correct part number. Maybe someone on here has the 160 and could have a look for you.
Also of course, once you get the new cover, secure it with something so it doesn't come off again. The problem must be with the latch not clicking in properly I think.
Good luck. Let us know how it goes.
