The wheel consists of a center layer of rubber that is stretched and held tightly by a series of rods, which can be adjusted for different types of terrain. The mountain bike version of the wheel includes 29-inch carbon fiber rims and is open on the sides, although it is being considered covering the opening with thin sidewalls to keep debris from getting caught in the tire. Besides eliminating the risk of flats, the wheel also helps increase performance by storing potential energy...

The bicycle GPS tracker will sound an alert if the bike is stolen, and then help you track it down and recover it. The bike GPS will mount inconspicuously inside the headset of the bike and will be secured by a special wrench. When the bike is parked, the user will active the GPS unit with an electronic key, which will turn on the vibration sensor. If the unit senses vibrations when it has not been turned off, such as in the case of being stolen, it will sent an alert through SMS...

The new cycling system will let you use both your legs and your arms while riding. The bicycle will feature a separate drive train that will be powered by the arms and will work with the pedal system. This will allow the rider to also use their arm, shoulder, and chest muscles to create forward momentum and encourages a better, full body workout. The adjustable system can be set for different arm lengths and the tilting action of the hand crank steers the front wheel.

A stroller will transform to a bike in under half a minute, and will provide a safer and more interactive method of biking with a small child. Rather than a bike trailer with the child riding in back, such a design will allow the parent to place their child up front, between their arms. BTW, the bike can also be adapted to other functions, with accessories including a shopping cart, weather cover, and car seat adapter.

The vibrobelt aims to keep cyclists safe and on-course, vibrating in different ways to indicate upcoming turns. Many long-distance bicyclists face the challenge of negotiating unfamiliar terrain while also reading a map or GPS device. The vibrobelt works with a GPS device to nudge the rider in the correct direction while still letting them keep their eyes on the road. Vibrating actuators indicate left or right turns as well as sending backwards or forwards commands, while coded...

The air purifier bike concept will let riders clean the air as they ride by filtering out pollutants and creating oxygen. The concept bike will be equipped with an air filter between the handle bars that will screen pollutants and dust and an oxygen-producing "photosynthesis system" that will include a water tank, electric motor and a battery. As the bike is being ridden, air will be forced through the filter and cleaned, allowing fresh air to flow onto the cyclist. The...

A new foldable bicycle helmet can adjust to the user's head for a safer and more comfortable fit. The helmet is made up of a group of rigid segments attached to adjustable straps, which allows the helmet to expand or contract in an accordion-like fashion. Once fitted to the user's head, it can be locked into place for a custom fit, and when compressed completely it will take up about 20 percent less space than a conventional helmet, which is handy for commuters and students with...

The idea is to put the bike light inside the handlebar stem, ensuring it's always there when you need it. The light will be enclosed within an aluminum stem that can fit most bikes. The stem will hold an array of ten LEDs that will send out a combined 500 lumens on high, illuminating an area eight feet wide and six feet at a distance of ten feet. The light can also be dimmed to 300 lumens or switched to a flashing mode, and light intensity and modes will be selected by the two...

The new bike lock will help discourage bike theft by disengaging the bike's steering system, making it a bit harder for thieves to 'snip, grab and ride.' The system will be integrated into the bike's stem, where it will be locked or locked by a key. The system will be securely fastened for riding, but a simple turn of a key will disconnect the handlebar stem from the fork--making it impossible for anyone to steer the bike. In addition to deterring thieves, the handlebar...

The new device makes cycling safer, and perhaps more stylish, by putting the rearview mirror on the rider's wrist. The device features a small convex mirror attached to a small, metal, snap bracelet. To use, the cyclist simply lifts their wrist to check the street behind. The wrist mirror is safer to use because it eliminates the impulse to turn the wheel to check behind while also providing a wider field of view.
