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.

Won’t Fit No Matter What
Size: 9.5, Color: Cs05 White, Size: 9.5, Color: Cs05 White
These shoes don’t stretch so I was unable to get my foot in the shoe. They are my size, but the opening has no stretch so you can’t get your foot in the shoe. I tried several different ways and then realized even though the shoe is the correct size, the opening was too small. They made the opening for the shoe probably the same size on all shoes, so unless you have kids feet you won’t even be able to slide them on. I’ve never had a shoe I couldn’t get on. I’ve worn Sketchers no problem. This is design flaw and I highly recommend you don’t buy!

These tennis shoes are so comfortable!!! I would recommend anybody to get these, especially if you do a lot of walking they’re very light but have a good heal support and the soul is nice and soft and cushy.. They’re also so cute. I got the blue ones and red also.

Great Fit, Lightweight, and Totally Quiet
Size: 11, Color: New Black05
Great fit and very comfortable once you pick the right size. Lightweight, breathable, and completely silent on hard floors. No squeaks or “suction” sounds like some reviews claimed. Normal packaging, normal opening, no issues at all. Excellent value for the price.

Most comfortable shoes I've ever worn
Size: 11, Color: New Black05
First off, I was not expecting much buying a no-name shoe online, especially for the price. Boy was I in for a surprise... I've owned these for almost a full year, and can confidently say these are the most comfortable shoes I've ever worn. I normally wear a size 11 and these fit me perfectly. Prior to this the most comfortable shoes I had were some Cole Haans with the Nike air technology. These shoes are so lightweight, so comfortable, I can wear them all day long without feeling a thing. Whenever I (rarely) need to wear a different pair of shoes, I am immediately reminded of how much I used to hate wearing shoes and couldn't wait to take them off. Based on the price, I expected them to wear down quickly. However they are still going strong. Running, hiking, long walks, biking, worn to office / casual events. These shoes have been soaked in mud multiple times, but clean up easily by just throwing them in the washing machine and then the dryer. The soles and the insoles have both worn down a bit over the past year; at this rate I expect to get 1.5 to 2 years out of them before needing to be replaced. So far I must have put at least a thousand miles on these shoes based on how much I wear them. They look good too. I have the all-black pair, and they look decent with jeans and a button up shirt for a night out, but also look natural in an athletic setting with shorts and no socks. Very versatile and subtle. Now for the cons, which are minor. The pattern on the bottom of the sole is prone to some squeaking/suction sounds at first. However after about a month some of the ridges wore down just enough that it was no longer a problem. Second: they are not as breathable as I would have liked. For example, when running or biking, you don't feel any air on your feet. Wearing them out in the sun on a hot summer day, your feet will get a bit stuffy. In fact the fabric is woven tight enough that I wear them in the winter and in the rain, and don't get too cold or wet. So I do wish they made a more breathable version for summer time use. All that being said, these are still the best pair of shoes I've ever had. Ultra light weight, comfortable, and can be worn all day long without feeling any fatigue whatsoever. --- UPDATE: It's been 1 year and 9 months, and the soles on these shoes are fully worn out and ready for replacement. Considering I've put between 1,000-2,000 miles of walking in these, that's pretty good. If anyone from Feethit is reading this, here are my top suggestions to perfect this shoe: 1) Easy fix - change the tread pattern. The current pattern causes suction cup effect on hard floors until it starts to wear down. Simply add some gaps in the circle pattern in the tread and it will remedy that issue. 2) Most importantly, put a thin piece of durable rubber on the bottom of the sole. The sole does wear down after some time and lose traction, especially on smooth wet floors (e.g. in the rain, in a kitchen, etc.). A thin piece of durable rubber would add more traction and also extend the life of the cushion-like sole (which is fantastic, don't change it!). This would easily be worth an extra $5-$10 in the price.
