bad, bad bicycle, should never have been allowed to be manufactured this way. Heavy low grade steel with pressed parts. Poor to dangerous brakes, ineffectual gearing using obsolete style of rear derailleur which relies mostly on the rear wheel bolts to hold it on, wheel rims too wide for the braking to be effective, let alone the fact that they are chrome plated. easily damaged seat post liable to bend or snap, saddle clamp allows for seat movement at inopportune moments, plastic pedals lethal in the wet offering no grip. Screw on cassette of the type where the freehub part often fails, one piece chainset & BB has to be replace if teeth wear, no replaceable rings, pressed steal makes it very heavy. Shifters are simple thumbies which often loosened off allowing for 'ghost' shifting. In short, a very bad poorly though out bicycle designed to mimic more expensive models and whose sole purpose was to generate as much profit as possible using the lowest possible quality parts: Mostly found abandoned in bike racks, train stations and your local tip. Heavy, difficult to upgrade AVOID - IT IS NOT AN 'MTB' AND SHOULD NOT BE TREATED AS SUCH!:
