Duotts c29
This is my second Duotts bike (the first one was unfortunately stolen). Overall, it's a sturdy, reliable bike. Unfortunately, the second bike is less resistant to moisture. After six months of use, the chain and fork rusted, the rear light broke due to moisture, and most likely the display broke for the same reason. The Netherlands has a very humid climate (humidity is almost always over 70-80%). However, customer support is excellent – replacement parts have always been sent very quickly. The batteries are high-quality. I haven't noticed any loss of capacity. Overall, I highly recommend Duotts products!
