I started with an ST2, almost everything was changed on the bike. Almost under warranty but how many times I found myself on the side of the road pushing it (I took out breakdown insurance so much that it was serious). How many days off or recovery time I had to take because I didn't arrive on time. How many days the bike was at the dealership (we're talking in months over 3 years). In principle I do 10,000Km/year I sold the bike with 28,000Km, when it should have had almost 40,000Km!!! I still had to take care of a lot of repairs (fork bearings, front wheel bearings, etc.) Info from the salesperson, I had no luck, it was the Monday bike. I keep my confidence and after 4 years on the ST2, I buy an ST3 Woe is me, even more problems. The bike had not yet left the showroom when the front headlight was not working properly, the brakes were mounted in reverse (front for rear and vice versa). Today the bike has 9000 km over 2 years, I should have had almost 18,000 km It has been at the dealership an incredible number of times for non-stop repairs. Still the majority under warranty, but still with the same drawbacks. At my expense fork bearings at 2000Km, broken spokes on the front wheel (then it was replaced under warranty), recently, front wheel bearings. The bike is not even 2 years old and I am more than €500 out of my pocket in repairs which should be covered by STROMER The bike is not entry-level, I bought it for almost €9,000 I can only advise anyone against buying a STROMER, they all have problems. And as long as you are under warranty, you will only get a small amount :) Regularly it is necessary to replace the motor wheel (1500€), the front wheel, the brake set, the motherboard, the control console, the V-shaped headlight, etc.
