Velobike battery extender

[Brendan]

I am considering purchasing an X35 battery extender from Velobike, does anyone have any experience of these products from Velobike

Hi Brendan - did you buy an extender? Experience?

I have an extender for x35, used once to try it, works no problem but I really don't need it. I would sell, if interested contact me
