The New Rental FleetRentals are constant, so to make our tough KHS Green even tougher we replaced the chain with a stainless steel one, changed out the bottom bracket to a sealed version and put thorn resistant tubes in the tires…..this is a real urban machine- by the time we’re finished we should have between 20-30 of these tanks pounding the beautiful streets of the greater cambridge/Boston. If the mayor of boston is still thinking about that free bike program he should really look into a bike that works all the time and can be fixed anywhere… about we hook you up with 5000 of these bad boys?
