Rockrider ST900, Kids' Mountain Bike, 20"

Very nice children's bike. Unfortunately, the size specification from Decathlon is not exactly appropriate. It is only correct if the child should reach their feet to the floor on the seat. Like us adults, my son rides on the pedal with his knee straight. This makes this bike just enough for children with 125cm. It went back and was swapped for the same one in 24 inches. That fits from 125cm and drives great.

I bought this bike for our daughter in the branch in Kiel because our daughter got along with it straight away and urgently needed a bigger bike. Unfortunately, I noticed at home that the rear derailleur protection bar was missing, which is important for a child's bike that is sometimes robust. I immediately called Decathlon, but got the announcement that I could come back to Kiel, then they would grow this for me there. For me as a Flensburg native, this is of course not a sensible option. Here I would have liked the part to be sent to me in the interests of customer service. Hopefully the bike won't take any damage until the part is somehow with me. In addition, the online images also show bicycle lamps and spoke reflectors, which my son's bike (online purchase) was also equipped with. It's a shame, but I don't get any benefit from buying it in a store if the bike is incomplete.

Great color, great handling. My son likes it and we've done long tours together. So far nothing to complain about for the price.
