Mejor una gama no tan baja

A friend from work wanted a 20" bike for his niece for her birthday. I think it doesn't make sense to buy new kids' bikes, so I searched Wallapop and found him a Btwin Riverside 500 from Decathlon for €35. It costs €230 new and looked in very good condition. When he brought it to me, I was able to fine-tune the brakes, but the derailleur was no good, so I had to change the shifter and rear derailleur, and even then, that's what happens with low-end bikes. In the video, I say I've never had problems adjusting the derailleur on these bikes, but then I looked back, and there have been some that have given me a hard time.
