Thank you for this very informative write-up. I have also re-greased my M620 using the red Mobil grease. I have since then noticed some YouTube video using the Corn Head grease. Would you have an opinion as to which type of grease is best for the M620?
This will be of special interest to owners of Hydra bikes equipped with a Kindernay IGH. There was significant interest some time ago to the possibility of replacing the Hydra chain drive with a belt drive assembly. The difficulty was the non-availability of a belt tensioner that could...
A word of caution when using the Hydra 52V 10A charger.
After 5 months of inactivity with my Hydra, I attempted to recharge the 52V battery. I am using the 10A charger that WW provides along with the battery. Plugging the charger in the electrical outlet resulted in a large spark. I then noticed...

I would just like to add that I got my Hydra with a Kindernay at the beginning of August and after riding about 500 miles I have not seen any oil leakage so far. Perhaps I have been just lucky with that batch of Kindernays.
Congratulations on your bike! Very nice look. I am getting a similar behaviour when charging the battery. I initially wanted the Satiator to set the max charging at around 85%, as it better extends the battery life. The Satiator was not available at the time of purchase and I got the WW 10 amps...
