The superlight, versatile children's bike with 20″ wheels, a safety-conscious design, BMX-style bars, and seven easy-to-operate gears for kids aged 6 and up. Kickstand included.

The time has come for your child to learn how to shift gears! With easy twist-shifting and a child-friendly gear indicator, the GO 4 is the perfect bike to learn on. From now on, you and your child will be able to set off on longer-than-ever expeditions with uphill or downhill stretches. A whole world full of new and exciting adventures awaits!

FEATURES:

  • Minimum weight. Maximum fun: Lighter bikes are so much easier to handle – and that means your child can focus on having fun. That's why our woom GO bikes only weigh around a quarter of your child's weight. You'll know you made the smart choice when you inevitably end up carrying your child and their bike (you can thank us later).Green rear brake
  • Child-specific geometry: The carefully designed frame allows your child to maintain their natural walking posture, making learning to ride a bike easy and intuitive for them. They'll feel comfortable and in control at all times, and thanks to the low entry, they can get on and off the bike safely. 
  • Protective handlebar grips: With their narrow diameter and ergonomic shape, our handlebar grips are made for small hands. Your child won't have any trouble holding on tight with a good grip. Plus, the special material and large outer diameter reduce the risk of your child getting injured.
  • Child-friendly brake levers: It's so important that your child can brake safely whenever they need to, so all our woom GO bikes have child-friendly hand brakes. Your child will immediately be able to spot the all-important rear brake because the lever and rear brake pads are both green (up to size 3). Plus, you can make sure they can easily reach the brake by adjusting the distance between the lever and the grip using the little barrel adjuster.
  • Steering assistance: Children who are learning to ride a bike often end up falling because they overturn the handlebars when they're setting off or turning corners. That's not a problem on the woom GO. All our bikes (up to size 3) come with a flexible steering limiter designed to keep your child safe. Think of it as their tiny trusty co-pilot.
  • Intuitive shifting: Kids usually get excited about learning to shift – but it can also be overwhelming to start with. That's why the woom GO 4 has a twist grip shifter equipped with a child-specific gear indicator to simplify things. To get started, all your child needs to know is that the rabbit is fast and the turtle is slow. 
  • Adjustable components: The handy corresponding ABC markings on the seatpost and handlebars (on size 2 and up) make it easier for you to precisely adjust the woom GO to your child. The bike grows with your child so they can always sit comfortably – even after another growth spurt. 
  • Ergonomic saddle: We know you want your child to feel confident and comfortable in the saddle from the get-go. That's why the saddle on each woom GO bike has an age-appropriate design that has been optimized to fit the size and shape of children's pelvises. To be honest, our saddles are so comfy that your child won't want to sit on another bike ever again.

Great book to understand Iran's strategy in a historical context
Nasr provides a solid understanding of Iran both in contemporary and historical context. It makes the case clear what and how Iran is thinking. Reading it at the time of Us-Israel and Iran war helped make sense of the news media, which often follows shallow analysis.

Iran’s Strategic Error.
Format: Audiobook
Excellent discussion of Iran’s grand strategy in what they believe will protect their Nation as they continue as the world’s pariah. The book is well written and clearly lays out the history of Iran over the past 50-60 years and why they are implementing this strategy albeit a failed one, and the results. The Ayatollahs continue to pursue the destruction of Israel and struggle via terrorism and supporting war proxies to become the regions power, instead of pursuing economic wealth. This book describes the how’s and whys of this failed strategy. Good reading

Highly Recommend
Format: Hardcover
A must read, especially during the current circumstances, for anyone wanting to have a better understanding of the nuanced Iranian political strategy. This book not only clarifies how the current government of Iran thinks and operates but also why it does what it does. Contrary to the western narrow and wrongheaded perception of the Iranian regime as an fanatical religious theocracy, the book lays bare different approches the Iranian government takes to different problems and shows how many of those decisions are not based on religious convictions. Decisions are made for pragmatic and historical reasons and until the Western governments understand what the issues are, they will not be able to find a path forward that does not include violence, war, and mass casualties. During these times that you have ignorant American Senators that push for war on behalf of a foreign government and don't know the most basic facts about Iran, I wish every American and European politician would read this book before uttering another word.

A good explanation of Iran’s conduct
I think this book explains quite well how Iranian leaders think and why the country is so engaged in various conflicts in the Middle East.
