Tallbike
A Tallbike is an alternative form of Hochrads. This design was created in the 19th century. It was used to light street lamps with gas operation. 2001 auctioned, the auction house " Sotheby's " a 1898 -built Giraffe Lamplighter Bicycle for $ 24,000.
Nowadays Tallbikes mainly by bike clubs and bike - yourself workshops, built for fun eg Bike Kitchens. These two bicycle frames are placed above one another and are welded and connected to the forks of both wheels. In addition, other arbitrary shapes are possible, the imagination knows almost no bounds. There are almost all types of bicycles as Tallbike.
Everyday use
The use of public transport space with Tallbikes is allowed as long as the requirements for a traffic compatible bicycle pursuant to § § 64a, 65, paragraph 1 and 67 of the Road Traffic Licensing Regulations ( Road Traffic Licensing Regulations ) are complied with.
Handling
The ascent and descent is similar like in a horse from the side. The pedal in the down position it has the stirrups function. The hands are on the handlebar, the left foot is placed on the pedal. In this case, however, the Tallbike must roll because tilting then can be compensated by steering movements. Before you go up, therefore, brings with it one or two steps in motion. The descent should shortly before or directly to a halt.
While driving, the Tallbike is more stable than a conventional bicycle. Even at extremely slow speed only small Kipptendenzen are noticeable. The reason for this is the moment of inertia. A broomstick, for example, on the fingertip balancierbar much easier than a pencil, a long rod falls more slowly than a short rod.
Types
The " standard " Tallbike two bicycle frame are welded to each other.
With only one frame, it is possible to build a Tallbike. For this purpose, a gooseneck Female Frame is turned on its head ( bottom bracket now above), fork and handlebars are replaced accordingly and then extended the seat tube and the stem upward.
At Tallbikes shifted by the reclined seat tubes in conjunction with the increase in the focus by the second frame backwards. Therefore are ideal steep seat tube angle of the bicycles used plus a long rear of the lower frame. The stern-heaviness may otherwise be reduced by using a smaller front wheel or by an extended rear of the bicycle.
As Reisetallbikes are, above all bicycles with a wheelbase extension. Due to the height of a Tallbikes arise in the context of space for additional cargo restraints.
In addition to the use of standard frame own individual frame structures are possible. They require a little more technical skills and knowledge of statics. Especially at high Tallbikes they are useful in order to determine the weight distribution regardless of predefined geometries.
Series production
The Dutch company had " De Fietsfabriek " a Tallbike model " Hoge fiets " in the program, which in 2013 was only available as a residual item in a Dutch bicycle market. The aluminum frame is reminiscent of a pentagon. The Danish company " Batak " sold a model "Tall Bike" as a promotional bicycle with square top frame that is best suited for a poster.
Records
Terry Goertzen from Canada ran a 5.55 meter high Tallbike over a distance of 300 meters on 26 June 2004. The ride is still regarded as a world record.
The " Skycycle " Tallbike Canadian Brad Graham was approximately 4.35 meters in height handlebar (14 -foot, 3 - inch) in 2005 recorded the largest wheeled Tallbike in the Guinness Book of World Records.
A record attempt by the American Michael Mooney in 2008 with a 13.5 meter high Tallbike ( and lifeline of a crane ) failed after a fall, injury and damage to the frame.
In Los Angeles in 2013 was a 4.42 meter high Tallbike (saddle height). It has been successfully run, but not filed for record. The builder has now built and driven an additional, 6.16 meters high Tallbike (handlebar height).
The Cuban Felix Guirola 2012 has built a 5.60 meter high Tallbike and hopes for recognition as a new world record. He even plans to build a 12 -meter-high Tallbikes.
Tallbike Jousting
Tallbike Jousting is a competition in jousting in the Tallbike. The lances are usually made of PVC tubes and padded with foam on top. 2004 World Cup tournament took place in the Vondelpark in Amsterdam, which won Bike Ryan Doyle from Black Label Club from the USA. The "official tall bike jousting champion of the world" also designed the iOS video game "Tall Bike Joust ".
