I am not familiar with either model since we don't have either one in the US, but I think either one is good quality--Shineray has been around for a long time now, and seem to have quality products. Keeway, from what I have read about them, seem decent, but they might be OEM'd by different companies. Maybe not, and all bikes are manufactured by Qianjiang Group (try to research Qianjiang) I think I would lean towards choosing the Shineray, but that is based on the fact that I am more familiar with Shineray, and they are definitely a large manufacturer in China.
