Hello there, I am going to buy a car, so I want to sell my bikes. Both bikes are in perfect conditon, there is nothing to be fixed or changed including oil. They all come with gas plate and blue book. Welocome to have test drive near wedaokou, I am at Peking university. The price is absolutely low, you even can make money if you sell them in spring and summer time. The bule is made in 2000, the dark blue is made in 2007.
