One of our two 2 year old Blix Vika+ folding eBikes experienced a Controller failure a few months ago when it hit a bump in the road. Initially I thought it might must be a loose or poor connection but re-seating all its connections failed to fix the problem. Having two Vika's I was able to swap their Controllers so I was able to establish we do have a problem Controller. I ordered a new Controller from Blix a couple of months ago but it seems they're having a problem filling the order, as I've been waiting a couple of months now, and the company says its still back-ordered. I'm curious anyone else has had a problem with their Blix eBike Controller, and if so, how did it take you to get your replacement? I'd also be interested in knowing if the Blix Vika+ has a generic Controller replacement?
