Believe it or not but the sensor of my vekkit kit started working again, was trying again last week to charge and test it and the motor suddenly kicked in
Not sure why it malfunctioned for so many weeks as I have been trying many times to make it work. This doesn't change the fact though that there is no response whatsoever from Vekkit, several mails I send over the past weeks have remained unanswered. Almost sure now they went out of business, let's hope that my Vekkit kit keeps working because if it does it's way more fun to ride my Brompton.
If anyone has a Vekkit battery (10Ah) to sell ...
I hope you do find someone that can send/sell you a battery, that's the problem you have with Vekkit as every part they make is custommade and you can't find generic replacement parts.
