Fitness mongoose bicycles have most of the advantages of regular road bikes–lightweight frames and relatively narrow tires for efficiency on pavement–with a flat or upright handlebar. These bikes are designed for people who want a light, high-performance bike, but don’t like the drop-handlebar riding position of a regular road bike. These bicycles are sometimes called flat-bar road bikesor performance hybrid bikes. Most of them can accept somewhat wider tires, to make them suitable for use on unpaved trails. They usually have the ability to mount cargo racks and fenders, which make them good commuter bikes.
Since cyclists’ legs are most efficient over a narrow range of pedaling speeds, or cadence, a variable gear ratio helps a cyclist to maintain an optimum pedalling speed while covering varied terrain. A dérailleur system normally has two dérailleurs, or mechs, one at the front to select the chainring and another at the back to select the sprocket. Most bikes have two or three chainrings, and from 5 to 11 sprockets on the back, with the number of theoretical gears calculated by multiplying front by back.
We are always looking for good people to work in our local stores — including sales, assembly, and mechanical staff. Job openings now available in various Landry’s store locations. Pick your preferred location and most convenient time to bring your bike in for some much needed attention. Choose “at my home or work” for mobile service in the Southbay.

The term “city bike” doesn’t really refer to a specific category of bikes; it’s more of a general descriptive term.
Since then aluminum alloy frames and other components have become popular due to their light weight, and most mid-range bikes are now principally aluminum alloy of some kind.[where? ] More expensive bikes use carbon fibre due to its significantly lighter weight and profiling ability, allowing designers to make a bike both stiff and compliant by manipulating the lay-up. Virtually all professional racing huffy beach cruiser now use carbon fibre frames, as they have the best strength to weight ratio. A typical modern carbon fiber frame can weighs less than 1 kilogram (2.2 lb). If you are buying a bike to ride with a group of friends, buy something similar to what they ride.
From a mechanical viewpoint, up to 99% of the energy delivered by the rider into the pedals is transmitted to the wheels, although the use of gearing mechanisms may reduce this by 10–15%. In terms of the ratio of cargo weight a bicycle can carry to total weight, it is also an efficient means of cargo transportation. Although bike and cycle are used interchangeably to refer mostly to two types of two-wheelers the terms still vary across the world. We’ve made our entire catalogue of bikes, clothing and gear available online at roll.shop for click and collect, with many items available for same day pick up.
