Trikes Useful Informations

A trike is a motorized three wheeled vehicle, often with an appearance closer to a motorcycle than to a car. These machines have increased in popularity in recent years, being seen as an excellent alternative to motorbikes. There are strict definitions of what most owners think of a trike as being. A motorcycle with a sidecar is not, for instance, seen as being one, despite the fact that it has three wheels.

Another important development has been in the way that the machines look. Specialist firms have been keen to spruce up their trike designs, producing machines that look great, as well as offering the expected performance levels.

Whether such models gain popularity will be interesting. One thing is for certain – trike owners will continue to enjoy the experience of riding these unique vehicles.

Tricycles are typically used by children between the ages of two and four, after which point they usually switch to a bicycle, often with training wheels. Parents choosing a tricycle for their child should ensure that the trike is not too tall and that the seat is too high, and that the wheelbase is wide enough, because if this is the case, the child may tip over easily. The seat should be stable, which is not always the case with the most inexpensive models. Some trikes have back rests which provide support and a push bar for parents so that the parents can push the child up hills or hold the child back when descending, or in case of the sudden approach of other traffic.

Adults may find upright tricycles difficult to ride because of familiarity with the counter-steering required to balance a bicycle, in which the weight of the body is used during turns. The variation in the camber of the road is the principal difficulty to be overcome once basic tricycle handling is mastered. Recumbent trikes are less affected by camber and, depending on track width and riding position, capable of very fast cornering. A few trikes are designed to tilt into the corners much as a bicycle does, and this also renders them more comfortable on cambered roads. They are referred to as tilting three wheelers (TTW’s).

Recumbent trikes often brake one wheel with each hand, allowing the rider to brake one side alone to pull the trike in that direction. This has led to a geometry (also called centre point steering) with the kingpin axis intersecting the ground directly ahead of the tyre contact point, producing a normal amount of trail. This arrangement, elsewhere called “zero scrub radius” is used to mitigate the effects of one-sided braking on steering. While zero scrub can reduce steering feel and increase wandering it can also protect novices from spinning out and/or flipping.

An often-noted problem with recumbent trikes, much debated by trikers and recumbent riders of all kinds, is their poor climbing ability: the rider cannot get out of the saddle and stand up on the pedals to climb hills. Trikers argue that they make up the time lost going up hills by going much faster on the downhill side because of the low, aerodynamic riding position.

Most cycle rickshaws, used for carrying passengers for hire, are tricycles with one steering wheel in the front and two wheels in the back supporting a seating area for one or two passengers. Cycle rickshaws often have a parasol or canopy to protect the passengers from sun and rain. These vehicles are widely used in South Asia and Southeast Asia, where rickshaw driving provides essential employment for recent immigrants from rural areas, generally impoverished men. In the 1990s and 2000s, rickshaws have become increasingly popular in big cities in the UK, Europe and US, where they provide urban transportation, novelty rides, and serve as an advertising tool.

The largest manufacturer of recumbent trikes is Sun Bicycles who make both tadpole and delta trikes. The deltas are built from designs licensed from Gardner Martin’s EasyRacers, the premiere maker of recumbent bicycles. Sun bicycles are factory-made in Taiwan and are among the least expensive trikes of good quality.
