Buena compra. Llegó antes de finalizar el plazo de entrega. Instalado en la bici sin problema alguno, eso si, la batería montada en portabultos trasero. Por su tamaño no entraba en cuadro pequeño de mujer. Buena atención del proveedor, tuve una duda con la batería y me la resolvieron rápidamente. Muy contento con la compra
