I bought Varstrom rear motor wheel and a battery for the rack to use it for delivering food and I have it for few months already and I think now I can give my honest opinion about it. Overall the product is good, but the quality - not so much. In the beginning, when I received the product, the wheel was with loose spokes, so I had to tight them myself. The spokes were terrible - they were breaking very easily. On all my bikes I've never broken a spoke before, and with this wheel I broke 6 for the first month. I had to order separately from different company thicker and more durable spokes, so they can last longer. I presume that in the near future I'm gonna have to change the rim too, because it seems that it's bending very easily and I'm not even riding the bike in the mountain. The battery doesn't last much if you want to go full speed all the time, but if you ride at 30-33 km/h, you can manage to ride 5-6 hours, also depending on the weather. Few weeks ago the wheel stopped working. After describing what the issue was, the guys from Varstrom were so kind to send me new controller and the problem was solved, so kudos for that. Although when I was breaking the spokes, they didn't answer my message. Maybe the warranty doesn't cover that, I don't know. Anyway the quality of their spokes is s**t, so they wouldn't help me much, but they could've still answered. It would've been nice thing to do. So generally the quality of the wheel is awful, not to mention that I had issues fitting the wheel to my very standard Specialized frame. My advise for them would be to put thicker spokes and to make more durable rim, because the wheel is heavy and in my case the battery for the rack adds extra weight for the rear wheel. The battery and the rest of the accessories are okay. The issue with the controller I believe was that some moisture got inside and maybe to some degree was my fault too. There is room for improvement here too - maybe to make different design and to be more water resistant. To summarize, I could've got better value for the money I've paid. I see Bafang (also sold from Varstrom) are little more expensive and I wonder if the quality of their products is better. I'm still using the wheel though and it does the job, although I have issues from time to time.
