Re: To short derailleur hanger for Nexus 3 IGH with chain tensioner

Couldn't wait for shipping of extender, so I just made one myself :) Made out of 316 stainless steel. The treads on the Shimano derailleur is very fine M10x1, but after having been looking around at work, I actually found a threading die and a tap that was M10x1 :D The plate is sandblasted Weary hap...

Re: To short derailleur hanger for Nexus 3 IGH with chain tensioner

That's was not a bad idea. I also think now that the goatlink is a better option for me. Because the chain tensioner is not in line with the sprocket. If I use the goatlink I mayby not need to use spacers on the chain tensioner because the goat link moves it outwards. Can you post a picture of your ...

Re: Just received a 48V pack from Aliexpress. Did I get bone

I was thinking a long time to buy this battery, but luckly I did my research.

You need ...

Re: Programming the Bafang Middrive BBS01+BBS02

There are plenty of people who say Kelper’s settings are very reliable, but I have not tried them yet so I cannot say. I would not advise using Kepler’s settings at a full 25 Amps, as you are asking for trouble. 100% Limit Speed at every PAS level at is going to put a serious load on the cheap-ass ...

I am actually thinking of buying the Cycle Satiator
If LunaCycle had a 220V version of their 48V charger, i woud go for that, but they only have 52V version for 220V!

The spec is on the charger: 54.6V @ 5A I am measuring 54.7V when nothing is connected to it, so thats n...
