context_page_description: Ice speedway is a developed form of motorcycle speedway racing, featuring racing on frozen surfaces. The sport uses bikes enhanced for the terrain. Participants can compete at international level.
context_section_description: The bikes bear a passing resemblance to those used for speedway, but have a longer wheelbase and a more rigid frame. As with speedway, the bikes do not have brakes.
  The sport is divided into classes for full-rubber and studded tyres. The studded tyre category involves competitors riding on bikes with spikes up to 3 centimetres in length screwed into each treadless tyre, each bike has between the 130 and 140 spikes on the front tyre and between the 170 and 190 on the rear (regulations on length and types of permissible studs are controlled by the sanctioning body). The use of these spikes in this discipline necessitate the addition of special protective guards (similar to mudguards) over the wheels which extend almost to the ice surface. The spiked tyres produce a tremendous amount of traction and this means two-speed gearboxes are also required.
  The use of spikes on the tyres makes the sport more dangerous with fallen riders running the risk of being run over by other bikes. Ice speedway riders have often been described as both the bravest and craziest of all speedway riders.
