In the manual "Dear Customer, Your new Pentagon Sportbike leaves our factory in perfect condition" is. This is a sad example of active Kundenverars ..... My son fell after assembly with this bike because the handlebar was loose! Not because the 4 screws were not tightened, but the link could be turned to the left and right while the front wheel pointing straight ahead! I tried to tighten all screws possible, but to no avail. For the price I have no miracles expected, but something? In addition, the rear wheel was determined to not let not rotate, namely, because the brake was stuck, but because the stock was stuck.
Update: I really wanted to return both bikes, but I was on the phone (I was called) can talk over, to exchange the bicycle. After a few days (!) The screws from the handlebars and some other parts are rusty. According to retailers this is quite normal for a bike in this price range.
