If you would like to buy a bike there are many different choices depending on your intended use. The first thing to consider is how much you would like to spend. If it is your first bike there are two things to bear in mind. Firstly, many new bikes get used very little, they usually end up gathering dust in the shed. Therefore, if you are not certain how much you will cycle maybe delay spending £2,000 on a carbon fibre prototype. Having said that, the more you spend on a bike they better quality you will be able to get. This is especially true at the lower end of the market. If you go from a £200 bike to a £400 bike the difference in quality is noticeable.
Hybrid - Commuter Bike
This category is probably the most popular. It involves the classic features of traditional bikes. A hybrid bike is designed for its usefulness and practicality. It is a cross between a budget mountain bike and road bike. Hybrids are ideal for commuting into town, especially when the distance is relatively low. If you have to do long commutes, it is advisable to choose a hybrid with thinner wheels and more in keeping with a road bike. Make sure you leave enough money to buy all the extras
Mountain bikes helped to reinvigorate bicycle sales in the 1980s. Mountain bikes enable a cyclist greater freedom in choice of terrain. They have seen many technological advances and you can end up paying a lot of money if you want. If you are never going to go off road, or even on a canal towpath, it is not advisable to get a mountain bike.
The classic road racing bike is designed primarily for speed. The drop handlebars enable a range of aerodynamic positions, the thin 700c tyres enable the least rolling resistance. These bikes may not be the most comfortable or appropriate for commuting. But, if you wish to do a lot of miles on the road, they offer the best cycling experience
