Trikes Useful Informations

Why have they become so popular in recent years? One reason has been that they are seen as a more stable alternative to a motorcycle. This makes them perfect for those with stability problems – this form of vehicle provides the thrill of riding a two wheeled machine, with the increased feeling of safety provided by that extra wheel.

Indeed, there are regular get togethers in the UK where bikers and trike owners meet. As with other forms of transport, there are environmental concerns surrounding the three wheelers. Some manufacturers are looking to ease such worries by attempting to produce more environmentally friendly models.

A tricycle (often abbreviated to trike) is a three-wheeled vehicle. While tricycles are often associated with the small three-wheeled vehicles used by pre-school age children, they are also used by adults for a variety of purposes. In the United States and Canada, adult-sized tricycles are used primarily by older persons for recreation, shopping, and exercise. In Asia and Africa, tricycles are used primarily for commercial transportation, either of passengers in pedicabs, or of freight and deliveries.

While most children’s trike have direct drive, a small number of models such as the Cheetah have chain drive. Unlike adult bikes, children’s trikes do not always have inflatable wheels; instead, some trikes have solid rubber wheels. While this adds to the weight of the tricycle and reduces the shock-absorbing qualities, it eliminates issues with flat tires, punctures, and leaky tubes. Since most trikes are direct drive, the child can slow the trike down by resisting the forward motion of the pedals, as with an adult fixed gear bike. Pull brakes are rarely used on kid’s trikes, but some “Bigwheel”-style plastic trikes have lever brakes in which an inverted half-moon-shaped brake pad is pressed against the driving surface of the righ rear wheel.

Typical upright trikes for adults have front and rear brakes. The front brakes are usually “pull brakes” or V-brakes, and the rear brakes can be pull brakes or internal drum brakes (which operate like automobile drum brakes).

Trikes’ strongest suits are cornering, stability, comfort, rider stamina and terminal velocity. Trikes can be used by adults who have problems riding bicyles. As well, trikes are a good choice for elderly riders who are worried about falls. Trikes can ride and climb at very low speed and a kickstand is never needed.

Trikes are always heavier than bikes of the same quality. In fact, the lightest commercially-made tadpole trikes, at around 30 pounds, are easily twice the weight of an upright bicycle of the same cost and quality. Deltas are even heavier. Shortcomings that potential tadpole trikers should realize center on the low riding position which makes them difficult to mount (grab handles are often available) and makes them hard to see in traffic, so flags and blinking lights are often used. Visibility concerns become minimal on bike trails and off-street riding.

Freight trikes are most often of the tadpole configuration, with the cargo box (platform, etc.) mounted between the front wheels. India and China are significant strongholds of the rear-loading “delta” carrier trike. Freight trikes are also designed for indoor use in large warehouses or industrial plants. The advantage of using freight trikes rather than a motor vehicle is that there is no exhaust, which means that the trike can be used inside warehouses. While another option is electric golf cart-style vehicles, freight trikes are human-powered, so they do not have the maintenance required to keep batteries on golf carts charged up. For more information, see the articles on “workbike” and “freight bicycle”.

Makers of recumbent trikes include KMX; Hase (who make the Kettwiesel delta, improbably named after the British children’s programme Catweazle); Inspired Cycle Engineering, who make the Trice range of tadpole trikes; AVD, who build the record holding Burrows Windcheetah or Speedy, a design exhibited in the Metropolitan Museum of Modern Art (MoMA); Australia’s Greenspeed, one of the oldest manufacturers; Michigan-based WhizWheelz, which makes 10 models, including a sub-US$1000 model tadpole and a tandem; and Big Cat HPV which builds the 6 Catrike models in Florida.
