Hi, There!
I’m just new here.
I’ve been using my Strida LT for 1 year and 6 months.
I use it on bimodal mode everyday, rain or shine.
Since i frequently pass to flooded road, the grease on my freewheel was melted due to water. 
I just want to ask your expertise on how to service my freewheel to have it a new grease?
What should tool to be use on removing the freewheel.
Also, please suggest any alternative or best grease to use.
Thanks in advance.
God bless!

(In this article you will find also links to other posts, via these you can find more images of worn-out freewheels.)
Maybe it’s possible to show us a pic with the teeth of your freewheel?
From here: Belt twisted twice
I’d recommend to buy a new one; the effort with the old wheel will not be worth the effect.
Mine was the plastic freewheel. I just got it serviced this year.
Things to have :
-Magnet or bowl to hold the ball bearings
-Degreaser to clean the ball bearings and the ratchet mechanism
Tips :
-put grease on the runners so that you can stick the ball bearings so you’ll be needing a thick grease for this.
-don’t put too much grease as these will just overflow at the gaps. The recommended amount is 2/3 of the space.
The mechanic didn’t use a pin spanner though. He used a screw driver and tapped at the hole on the freewheel to open it.
