Looking for a good bicycle shop for children bikes

Hi Mathias, this might not really answer your question, I can't really give any advice about a shop but I would like to recommend Loekie bikes to you. Loekie is a dutch bike brand made only for children. I bought my eldest son one in Holland about 6 years ago and it is now still in perfect condition and being used by my youngest. These bikes aren't the cheapest but come with everything your child will need (lights, lock, rack for schoolbag, etc). What I really love about these bikes is that in addition to hand brakes they also have "torpedo" brakes where the child just needs to pedal back to brake. My children always found this way of braking much easier when they were young. These are bikes made to be used everyday as a real form of transport and not as a toy and it shows! You can check them out on this site: www.loekie.nl Hope this info helps you out a bit!
