Hi I have a 2018 radrover. About 4K miles.  Its used exclusively for work.  I work on the beach so the bikes is constant salt environment.  Its even been hit by a wave while i was riding it.  Its my workhouse with a large front and rear basket.   Only issue I have had other than burning through brakes it the controller which i upgraded a few years ago.   My battery is now falling apart.  The plastic of the case is separating and I can barely charge it because the charging pin is deteriorating.

Not sure what to do?   Purchase a brand new rad rover?   repair or upgrade battery?  How long do these motors typically last for?   I can't be without the bike so I am willing to do whatever makes sense.    Look forward to hearing opinions!

Thanks
