Sure, you can find some details here : https://visforvoltage.org/forum/14235-problem-dougas-engeneering-firmware. If you drop me (me@mecano.hu) an email I can send you the files. Note, you will need a specific CAN bus adapter as well : https://www.peak-system.com/PCAN-USB.199.0.html?&L=1&no_cache=1&sword_list%5B0%5D=ipeh002021 (the opto isolated one).

Great. Yes you must* have a BMS for Li-ion cells, check the link Sylvain shared, that is the improved version of the original Vectrix design.

The ESD charger is quite old and far from ideal for Lithium. Even so it is kinda possible to use it with the so called Dugas software and firmware, however there is no guearantee it will work nicely with the above BMS mainly due to firmware compatibility issues. A gold charger (aka Runke v2 or v3) would be much better since those are proven to work with the BMS.

* In a nutshell the BMS controls the charger preventing overcharge and takes care of the balancing session as well.

You can apply 110-150 V DC indeed to the battery terminals indeed to check if the bike powers up. You will need to use an incandescent 40-100 W light bulb inline to prevent excessive inrush current that could damage the Motor Controller.

In the majority of the cases it is the battery. The rest of the Vectrix is quite reliable maybe with the exception of the chargers.

We have a reasonable stock of spare parts here in HU. Even so it would be great if you can share that link, should there be a need for some items from Matteo.

Hi, most likely it is permanently closed. It is already unreachable for a while.

That explains (I have VX1 which is not a hub motor design). Indeed seems to be custom with the 45 degrees valve position, I've just looked at the VX2 pictures showing the rear wheel from the right hand side.

Are you sure an inner tyre is needed ? The parts catalog has the follwoing items for the rear wheel :

SV30500 Tyre 130/60-13 Tubeless 1
SV30802 tube rear tire 1

In other words there is also an indication for being tubeless. In case it is still needed an ordinary inner tube for the 130/60-13 tire size should work I guess.

Just checked, great :)

Thank you Sylvain, apparently they don't have firm plans at the moment.

Regardless it could be practical to restore the shop for the customers or at least an email address for orders.I doubt it would cost a significant amount (vs. the inventory stored without any use).

To be honest I have never touched that encoder. You can try to lift the rear of the bike and try different things in the diag including reverse throttle if that is reversed as well.

You mentioned firmware update, you can try to go back to the original version if that fixes the problem. To this point if your battery is in proper shape the top speed should be more that 110 km/h indeed, with some versions close to 130 km/h.
