The product is very good I am satisfied to the extent that I buy the second for my wife
Purchasing and receiving the bike were quick and efficient, didn't feel the courier took great care of it. Likewise had a few niggles with the bike upon delivery inspection but Blacks customer service called me quickly and resolved the issue.
Bike itself seems very good value for the quality of components, and would happily recommend buying from Blacks.
