Bought two Vika+ Flexs for my wife and I April 2022. Was a little slow to get here but that was more FedEx's fault than anything else. My wife has the front basket attachment and the bike still folds up nicely (though it BARELY fits into the carrying bag now, which requires a lot of finagling to get right). I was a bit apprehensive about purchasing Blix bikes because compared to other brands like Radpower, Aventon, and others, Blix doesn't have nearly as big of a presence. All that being said, I was pleasantly surprised. The bikes are nice and sturdy and provide a great amount of torque, especially for me who is 240 lbs and at the very limit of what the bike is rated for. I even had some time with my 2 year old son in a Thule Yepp Maxi bike seat on the back of my Vika+ and it still had no problem pushing us along despite definitely being close to or above the max weight of the bike.
One thing I was concerned about prior to purchasing the bike was all the reports of tires bursting at the bead. When the bikes arrived, I did a very thorough check on all the tires and noticed that the front tire of one of our bikes had the bead riding up right above the valve. Turned out the inner tube was getting pinched by the tire. Fair warning: the 20" tires are TIGHT on the rim. If you plan on changing flats/tires on your own, make sure you have a SOLID set of tire levers because it took me a VERY long time to fix the pinched innertube. Any cheap tire lever from Amazon is going to bend before getting the tire off those rims. The Gorilla brand ones did seem to work for me though after a lot of effort.
Beyond that though, we haven't had any issues with the tires so far (we've only gone about ~20 miles though). The bikes also are great on the road, but are not really meant for much past some light gravel. The lack of suspension means you will feel every bump, especially if you go on some larger gravel trails.
Overall though, we are very satisfied with our purchase. Like I said before, we are extremely impressed with how sturdy the bikes are, and love the look of the bikes in general. As long as you give the tires a good once over before riding and you use the bike for its intended surface, you really shouldn't have any problems! I did a lot of research on all the other brands before purchasing the Vika+ Flex, and you're not going to find a folding e-bike that is as light, compact, looks as nice, and still has the power as this one. It's just a shame that more e-bike reviewers have not reviewed this bike.
