Cycle Ball

Cycle ball bicycles are twice as strong as normal sports bicycles.
Cycle ball bicycles have a specially designed shape and extra strength to satisfy demands for special movements such a turning, shooting, dashing, and stopping.
Diagram with Part Names

One-Piece Construction Rearward Saddle Placement Braking

Since a powerful force is applied to the handlebars when shooting, they are welded to the stem to make them into a single piece.

The saddle is attached to a seat post that extends out from the top tube to make it possible for players to pull their hips all the way back when playing, particularly when a powerful kick is required.
There are no brakes. Players drag both feet on the ground to stop or slow the bicycle.

Acceleration Gear Ratio Ball

To make possible split-second movements such as dashing, stopping, and backing up, the front and rear gear ratio is fixed at nearly 1:1 to enhance acceleration and control. Gears must move the bicycle between 2 to 3.5 m with each full revolution of the pedals.
17 to 18 cm diameter

500 g to 600 g

This perfectly round ball is packed solid with scraps of cloth, kapok, or other such material.

Thick Chain Rims Uniform

A thicker than normal chain is used due to the intense force placed on it during the game. Either wooden or metal rims are used. Consists of a t-shirt and shorts.

Double-Size Tubing Cap Nuts Long Socks

Frames are made of tubing that is twice a thick as what is normally used in order to withstand the extremely strong forces generated by continuously shooting and turning.
To prevent players from getting injured, acorn nuts must be used on the front and rear hubs and chain nuts.

1. The ends of the hubs are capped with acorn nuts.
2. 24-teeth chain wheel
3. 22-teeth fixed gear
Protects the lower legs from contact injuries during play.

High-Top Shoes

Shoes such as those designed for basket ball are used to protect the ankles from injuries resulting from contact and spills during play.
The basic play in cycle ball is hitting the ball with the front tire.
Cycle ball is an indoor sport in which two 2-player teams compete for points by scoring goals. There are two 7-minute halves plus a 2-minute rest period. Victory goes to the team that hits the ball into their opponents goal the most times, thereby racking up the most points. Tournaments are round robin league competitions.
Corner Marks Offense/Defense Heading

These are marks placed near the four corners of the field. Whenever the ball crosses the goal line, it is placed on a corner mark and play resumes. Players freely tradeoff offensive and defensive positions. The hands are not allowed to touch the ball. As long as both feet and hands do not stray from the designated areas of the bicycle, players can hit the ball with various parts of the body including the head.

Basic Play Kickoff Goalkeeper

Offensive and defensive players must grasp the handlebars with both hands, and with both feet on the pedals, use the front and rear wheels to pass, hit, shoot, and perform other basic plays. Players on both teams place their bicycles on their own goal line and wait with both feet placed on the field. At the sounding of the starting gun, one member of the team chosen by the draw advances to the center line and hits the ball placed there to start the game. The kickoff is repeated each time a goal is scored. Team members freely trade places. While in the penalty area, the goalkeeper is allowed to use their hands, but outside it, they must observe the normal rules forbidding their use.

Positions Reentering Game

There are two players on each team, but their positions are not clearly assigned. They are free to exchange offensive and defensive positions depending on how the game is developing.
Whenever a player falls off their bicycle, touches the field with a part of the body, or touches a fence or other part of the field, they must return to their goal line and remount their bicycle before they can reenter the game.
