As you probably know, there are three types of bike
ROAD BIKES: dropped handlebars, narrow tires, after the tube shifters. Road bikes are light and fast and have significant advantages over other types of driving. You can also travel on dirt roads without much effort, they can not freely roam the land or sand. The disadvantage of racing in Berkeley, is that because of their narrow tires that are not compatible with the bumps and potholes, as well as other species. One advantage is that it seems the thieves are not interested.
Motorcycles, like Bridgestone RB-T, are the wheels with the tires on the road, and usually a relaxed geometry better handle bumps. I think they are good for my main commuter bike is a Schwinn Voyageur (unfortunately, not Schwinn). There are slower than other bikes, but faster than others.
One of the problems, the acquisition of a racing bike is that most shops are not cheap, so it is difficult to provide evidence of travel to $ 500 cheaper. Since I recommend a trip test, it is a big drawback.
Mountain bikes: a straight steering wheel, big knobby tires, handlebar shifters. Own mountain bike for the majority of new motorcycles on the market, which is fresh and fun to go watch (the people who want to ride on their bikes, they tend to not buy a mountain bike). There are significant gaps in the management and can also be used in loose soil or on a single track road. Significantly slower than road bikes on the road, yesterday was my mountain bike riding and felt like I had no energy at all. Also, objects thieves in Berkeley, and if you have a mountain bike, ready to provide extra precautions to protect it.
Mountain bikes are more comfortable because of his driving position in a vertical position, which is incorrect. This position is very convenient when you're only on the wheel, or perhaps sitting on a bike in the shop. There will be more pressure on your lower back, and the absence of additional parties also causes problems for long walks. Especially after the theft issue, I can not recommend in good faith on a bicycle in Berkeley. If you are looking for a bike everywhere you can, or if you want, specifically designed for off-road driving, mountain bikes are great, but I think that every day school is a bad idea, if only if you have a private office, where you can save.
Hybrids: After the mountain bike boom in the early'80s, people began to realize that her riding mountain bikes on the road. Since mountain bikes have a significant impact on the road, hybrids have characteristics of mountain bikes and road bikes. They tend to be in an upright position, but less than the mountain bikes. Your tires are wider than road bikes, but usually not too bossy. They often have a steering wheel from the position as compared to mountain bikes.
As you might expect, they are faster than mountain bikes, but slower than road bikes. The objectives of stealing more than racing, but less than the mountain bikes. They are better in the loose dirt bikes, but they are not suitable for serious off-road driving. I think that hybrids decent commuting bikes, horse riding, but in an upright position, it is desirable for long walks. For the city, but they are good. There is usually a combination of many of the choice up to $ 500 for casual users.
Are recumbents (bikes, when you sit in that looks like a couch) and tandems. Recumbents are convenient and attract much attention, but they are not climbing the mountain, but good flats and downhills. There is a growing market for lying. Tandem (bicycle, two men) were the most fun possible on two wheels, but the good are expensive.
