Used for 1 week or less
Very comportable ride perfect for uphill route the kenda tire are good in road and also off road terrain. Chain ring is welled played .but for me I think im more comfortable if I change the chain ring into 32 teeth it will give me more speed. cogs superb very smooth shifting.but the frame color need to have frame PROTECTION or put more sticker on the frame. But over all I will recommend this bike
