I have the Icoo pluto stroller and the front wheel got damaged. From where I can get the replacement?
I am afraid there's pretty much no way. The iCoo Pluto is a relatively older model that is long discontinued. The iCoo brand is now owned by Hauck and they do not sell similar models anymore. The only way to get a space part, from my point of view, is to search in classifieds - perhaps somebody is selling their own Pluto cheaply, which you can buy and use for parts.
I wish you the best of luck!
