Rad Rover battery won't remove with key, lock broken

[Tom Elliott]

3 year old Rad Rover with 7000km.
Battery is now stuck on bike and key won't release battery. Lock feels a little clunky, might be broken, or the little brass post that locks the battery in place is broken. How do I remove and/or replace loc?

Does the lock turn or not?  I saw on Youtube about someone with a similar battery on how to do it.

Now if it unlocks okay then you have different problem like I had.  My battery connectors expanded due to too much power flowing.  I had to use a soft rubber mallet to get it off.  I tapped it from the bottom. 

I did that a few times and then finally had to replace both male and female connectors.  If this is your problem I will send you the Amazon link of the part replaced. 

FYI....I have a 2020 Rover with 6000 miles on it.  So about the same age as yours but with more mileage. 

Good luck.

I can't pull loose the battery on my 2020 Radrunner. I pry between the bottom of the battery and the frame, using a stick or my fingers.

My 2022 Radmission was worse. I happened to have a length of 2 x 4 with one end cut to a 15 degree wedge. I'd slide the wedge in tight between the battery and the seat tube, then apply a little leverage. I worked on the locking tabs with a nail file. After several sessions, I could get the battery loose using my hand as a lever.

Radpower: it's not just a bike, it's an adventure.

I'd like to see that video. Do you have a link?

My 2022 10 AH battery appears to have the same case as my 2020 14 AH battery. I thought unscrewing the bottom plate would work on the 2022 because the lock is screwed to plastic that does not appear to be part of the bottom plate. Now I see that it would not work on the 2020 because the lock is screwed to the bottom plate.

In case the lock on my 2022 battery ever gets stuck, I tested my method by removing the screws. The screws on the two batteries look the same, but the heads on the 2022 are different. With the screws removed, I couldn't get the plate loose. Maybe it's cemented on.

The video might show me what to do if a lock gets stuck.
