Counter does not work, no service Amazon

No complaints about the bicycle itself that the price corresponds to my expectations although different difficulty level stops not used much since we noticed little difference of a remedy to another. For initiation and maintenance is enough. For cons, the battery meter does not work and this is where things get complicated: No way to join Amazon in whom control the bike, you can not do a full expulsion procedure through the site, while I did need a little meter that must be 200 gr. The only possibility to express myself here, so I hope that Amazon will react.
