Reinvigorating My Merida TEV550

Hello Merida TEV Users,
Anyone found a way to lube the drive gearing or have suggestions for maintaining that critical link? With 2000 miles and a new battery pack in a saddlebag, worry about the whine led to web review of currently active users.

I have posted information here and here:

Kevin’s experience of battery performance is similar to mine. I bought the bike from a gentleman that kept the battery on the charger constantly. The original pack failed a year ago. Lead acid batteries were left idle, off charger, in 70-80 *F for seven months. New charger, new pack of batteries using a turbo modification is near 20amps. The hack took a year to test and assemble and is stable on turf and dirt paths, still using belt and bungee to fasten to the frame.
