It will need height, shoulder, arms, feet, and other body measurements to provide you with the most accurate information. It covers road and mountain bikes. Once you provide this app with your information, it will provide you with two sets of specifications (for comfort or performance).

SizeMyBike lets you save your data and export it all using iTunes. Bike measurements can be shared via e-mail (in PDF format). This app may not work for the pros but could provide the rest of us with useful fitting information. It is a money saver too.

Looking for a killer Supercross game for your iPhone? That’s exactly what you get with 2XL Supercross. I have played a lot of racing games on my iPhone, but I have so far liked the car racing games better than Motocross ones until now. Supercross is a challenging bike racing game that lets you keep challenging yourself as you go on with the game.

The graphics of 2XL Supercross are simply amazing. You get 3D physics, surround sounds, and realistic game play. You can also compare your results with others by signing up on the 2XL Live server.

2XL Supercross is great if you want to kill a few hours. You get 3 modes of play (Time Trials, Practice, and Racing), and you get to choose among various bikes an. You can also reduce or increase the number of people you race against. And it does help when you’ve got cool tracks to choose from.

Verdict: A. There are not many applications that are perfect all around. 2XL Supercross comes closest to perfection. The graphics are simply out of this world, and the game is so entertaining, you’d find it difficult to put it down. And while a $7.99 application is not that cheap, 2XL Supercross is definintely worth the money.

LightBike is a cool 3D application that involves you riding a LightBike in the cyberspace. The game is very simple yet very entertaining. Once you start riding the bike, you leave walls of light on your track, and your goal is obviously to beat your enemy.

The Full Version of LightBike has 2 modes for those interested in multi-playing. In 2 players mode, you can split the screen into two. In Wifi mode, you can connect with your friends by wireless but keep your screen in full. All in all, 4 people can play this game at the same time. Here are the modes you get:

• 1 player mode: (3 levels of difficulty)
• 2 players mode: (split-screen mode)
• 2-4 players mode: (Wifi mode)

Verdict: 4.25/5. LightBike is a great game for the iPhone. I thought the game’s description on the iTunes was a bit confusing. The game was advertised as having Wifi over the Internet available but that will only be available in later editions. The game has so much potential, and it is fairly cheap. If you are running out of cool games to play on your iPhone, you should definintely consider buying LightBike.

Bike or Die 2 is a very interesting biking game for the iPhone. Now in its second version, the game has been improved significantly to make it more worthwhile. The game is created based on Physics-based bike simulation. You get over 2500 levels to work with, and you can record your best games (who wouldn’t want to brag?)

There is also a community of folks (Hall of famers) who share their time trials, which you can watch and learn from. The previous version was a bit difficult as you had to start from the very beginning when you died. The new version allows you to save locations.

Bike or Die 2 is a very cool game that is worth a look if you can afford it. It’s available for both the iPhone and iPod Touch.
