Before buying a bike, everyone should have a think about what kind of bike they need. How you intend to use it is important, as there are huge variations in design. When travelling in the city, no other form of transport will get you from A to B as quickly as a city bike. Cyclists have more fun on their mountain bike or racing bike than in the gym, and can work both their stamina and muscles at the same time. In contrast, off-road cycling with a mountain bike primarily requires being agile and using your strength intelligently.
