Bicycle frames are constructed from materials which place emphasis on being strong, lightweight and stiff to aid power transfer. Aluminium, titanium, steel and carbon are widely used in all levels of frame production.
Major bike manufacturers produce a new range of bikes on an annual basis and this determines the model year of a particular bike. This annual turnover is fuelled by advancing technology, industry trends and customer demand for a particular feature or style of bicycle.
Bicycle wheels come in a wide range of sizes from 12" wheels found on smaller Kids Bikes to larger 29" Mountain Bike and 700c Road Bike wheels. Larger wheels are normally faster and more stable at speed and their larger contact patch improves grip too. Smaller wheels are normally lighter, more manoeuvrable and have quicker acceleration.
Wheel sizes are defined by the country that first popularised the style of bike that used them - so you'll see some imperial and some metric measurements listed. Wiggle includes the ISO standard in brackets after each for ease of comparison.
A hybrid city bike is almost any bike that doesn't really fit the more distinctive categories. A basic mountain bike with faster rolling tyres instead of knobblies is effectively a hybrid, as is a recreational road bike with a flat handlebar and facilities for a luggage rack and mudguards.
Hybrid city bikes put their design emphasis on utilitarian transport rather than sporting use, although it has to be said that almost any bike type can be used for fitness, commuting and touring purposes. Hybrid bikes will use a variety of styles and components to suit riders with slightly different priorities.
Different manufacturers use different labels on hybrids. Expect to see 'Urban', 'Commute', 'Fitness', 'Lifestyle', 'Town', 'Dual Sport' or 'Multi Use'. Hybrid bike wheel size can be based on 26in mountain bike or 700c road wheels: either is fine, provided the tyres are tough, medium in size and fast enough rolling for easy speed. Sizing and ride position tend to be mountain bike influenced. Please consult Wiggle’s bike buying guide to learn more about identifying the right time trial bike for you.
