Yes but no one managed to connect to VESC Tool at this time

For my eppg, these are the parts I choose : ESC : VESC 75/300 Motor : T-Motor U15L Propeller : e-props 130cm Battery : 16s DIY li-ion The VESC is a very good one with lots of customizable parameters, and 300A of continuous amps with good cooling. Not so expensive But... that's still an...

Ok so... X1 Pro have better heat management and I believe it have a tougher sprag clutch too (280Nm max vs 150Nm) It appears the stealth is not a good choice for hard riding off road bike

What's best between the X1 stealth G3 ans the X1 Pro G3 for purely off road usage ?

The only reason I would buy a CYC is because I can't fit a Bafang BBSHD on my full suspension mountain bike, a Decathlon AM500S The sloped down tube on the AM500S bike doesn't allow enough ground clearance The only option is a motor that can be fitted inside the bike triangle, such as a CYC...

That's sad to hear ! I thought the X1 Stealth was designed such as an overheating is very difficult in normal mountain bike condition What is your battery voltage ? Cranking up the voltage to 72v will reduce the copper losses Others having overheating issue with the X1 Stealth ?

It will be interesting to know if 0.15mm copper is enough to support the future 4680 cells... probably not ! Maybe we will need 0.20mm, 0.25mm or even higher thickness copper and that's not possible to solder it reliably with the kWeld, even with nickel plated steel caps, slots, etc. We will...

That's why they told me that's an unofficial date...

I don't quite understand I have a mountain bike with a BB92 bottom bracket so I need to order the CYC X1 pressfit version, I don't have much choice And that's the case on most modern high-end mountain bikes Plus, it's actually easy to remove it with a standard pressfit removal tool After...

They have just received the freewheel 2.0 parts for the pressfit version It is now possible to order the new freewheel with pressfit bottom bracket

Interesting, I suppose 3000A is enough to solder 0.2mm+ copper sheet for very high current Li-ion application

from now on, is new X1 Pro / Stealth ordered will be delivered with the v2 freewheel ? EDIT : I see there's an option for the V2 freewheel when ordering but it is not available if you select the BB92 bottom bracket option. I don't know why

Well done How easy it was to tear off the copper/nickel sandwich ?

0.15mm copper sheet may be the sweet spot if it's easy to weld with the kWeld

I'm currently doing some soldering tests with the kWeld and 0.2mm copper sheet I picked 0.2mm copper sheet for my battery project but on second thought, it's probably overkill. The battery will be a 16S8P 21700 cells, with a max pulse discharge current of 250A-300A. From what I have read, 20A...
