I received it today:


Apparently it uses DOT4 oil... and my disc brake currently use mineral oil... Can I mixes these 2 during bleeding?

Are you still running on RC lipos cwah? Is the voltage holding up over time? I wonder how long these packs are good for?

I think he swapped those out for the larger Sony Konion cells a while back.

I'd chuck the Dot 4 and get some mineral oil.

Hech, on this bike I'm using Zippy compact with a pack at 72V20AH. In term of sag I only have 3V drop on full power at 2.5KW. So about 0.15V drop/cell on max power... Quite good but my pack is big :)
My brompton had these very nice konion. They were good too but had much more sag and were dropping to 65V under load (from 80V). Massive sag, but they were quite robust.

D8veh, shall I get this one?

Purchased it... Now I just have to wait until the bottle arrive...

Another problem, the cover starts to disintegrate:


I wonder if I can do something to have something more durable? I need to make it waterproof too!

God damn universal bleeding kit:


None of their thread fits my chinese brake one (on the right)... I have to send it back to the seller.

I think it was a mistake to buy a no name disc brake as bleeding as well as brake pad seem to be impossible to source :(

Wow, thats a transcontinental battery pack you got there cwah, you put us all to shame. 3v drop is pretty good up there in the megavoltage land we all aspire. Keep going!

cwah, isn't there a temperature problem with the waterproof fabric?

No, the pack is quite overpowered for my use. It doesn't get warm at all.

What a monster bike! You cope perfectly with normal traffic.

I have remembered when I was living in London, I lived quite close to that area, in fact. Pretty cool video and bike.
