I bought an electric fatbike called rumble 500. Ebike review: 4/5 Sportproffsen.se review: 3/5 I will update this review once something positive/negative happens so that anyone buying here has a good, fair and honest point of view. Ebike review: + Silent (especially compared with a zipforce) + Strong motor (the Rumble 500 had a slightly stronger motor than the Rumble 300) that seems to manage steeper paths. + Removable battery (good for winters!) + Cool look! + Jula's/Kayoba's cheaper mudguards fit on this bike. - Not possible to buy any spare parts/battery. Sportproffsen.se review: + Very quick delivery! + Very quick response before and after purchase. + I asked them why they had so many bad reviews before buying and received an email back with their point of view. - The bike came with a minor damage, and I showed them a video of it (before opening the package) but I received nothing in return. - I asked them for a longer cable length for the backlight as I want to have bagage on the backwheel, but then the lamp on the saddle is not visible anymore. They answered no, they don't have any longer. After investigation however, it seems to be super easy to buy an extension cable on amazon for example. They could have simply said this in my opinion, that would have been a great help. - The bike was not decently tested/configured. The highest gear takes 10-20 seconds before it finds its way. This could have been configured in advance. I think when buying a new bike, the bike should be fullly ready for the road. They adviced me to find the nearest bicycle garage to get it fixed. That's all the information I have so far. But as I said, I WILL come back here to update my review once something important happens. :)
