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.

Wow!
Format: Kindle
This book was awesome! Seraphina and her family have moved to a new town. Her family is a bit... odd. She grew up learning how to protect herself from people who might hurt her. Bloodshed is a daily occurrence with her brothers and parents during their practice sessions, and it’s all fun and games unless you need to hide a body. Sera’s family is very close, and she’s been homeschooled most of her life. But in this new town she is going to start regular school as a senior at the local high school. Unfortunately, things at her school aren’t all they seem to be. Or perhaps more than they seem to be. Sera has her own demons to deal with, and she’s terrified her new friends will learn about her weird family and other issues and drop her like a rock. It turns out they have their own secrets as well. This story ends on a bit of a cliffhanger and I can’t wait to read the next one! This book is well written and well edited. The heroine is spunky and has a great heart and wicked sense of humor.

A Fox Amongst the Wolves
Format: Kindle
Collette has been forgotten about her whole life. Her parents don't bother with her, others don't try either once they realize she uses sign language to speak, and she's a shifter surrounded by humans that hate her kind. On her 18th birthday, she runs away. She takes the train and then bus wherever it can get her as far from home as possible. A missed bus brings her and a mysterious but kind man to Willowdale. What happens next is a story of fated mates, shifters, magic, new best friends and found family, and a stolen child. I'm sad this was a shorter read but only because of how much I loved Collette, Dylan, Hunter, Luca, Lena, and the others in their community. I love how detailed the characters are even with the shorter story. You can tell their characteristics easily, and the lead in to book two is done so well. I loved this insta love book with just the right amount of drama.

An easy PNR book to cure book hangovers.....
Format: Kindle
I enjoyed this as a short story; but nothing truly pulled me into this world to want to keep reading each story. I can sense the overarching villain arc w/ the HAF; yet it still wasn't enough to capture me long-term. It felt like too much focus was placed on progressing the romance part that everything else took a non-existent back seat. This did work well for my intentions of getting over a book-hangover slump. So there's that lol. A Tip to overcome a PNR book hangover, from a wonderful series or novel......read a trope-y, lighthearted, PNR that is easily predictable but adorable. Like this book. Honestly, I'm rarely into short stories that are turned into a ridiculous amount of books on different PNR characters. So I'm not the best at judging the merits of these stories. I'm a long-haul type of reader that lives for a series surrounding 1 lead female character & her harem (or singular partner). Occassionally, I'll find a series of short stories that are interesting enough to finish or pull me in completely. The rarity of that is countable on 1.5 hands, compared to the literal hundreds of fiction books I've read lol. With all of that, I will say this was fun because of the FMC's difficulties growing up & how that made her strong, the end reveals of her life, & the cute Epilogues. I never felt truly connected to any of the characters; but I did feel slightly compelled to just finish it to see how plot points would end. Unfortunately, due to a lack of character backstory explanations, I still don't understand Collete's "magic". Very little time was given to flesh out the backstory of the world this occurs in. I couldn't even guess what type of magic occurs in this world, aside from what little was revealed. A random scene sticks out to me...... we're introduced to a new magic type, in passing. No dialogue to expand. No hint at anything really. Then the scene moves on. That moment felt pointless to even mention, afterwards. It felt like the author was more concerned w/ romance than storyline. This is a common issue I have w/ short stories....authors write them for whatever reason; but too often it's an "either or" theme.....EITHER the author is writing ONLY for romance w/ storyline taking a minor role OR writing ONLY for storyline w/ some romance that ends up feeling forced. As I mentioned earlier, only a handful of short stories series have ever had a balance of both sides, for me, that I wanted to read all of them.

Great RH shapeshifting romance!
Format: Kindle
Oh my gosh, I adored this book! Voiceless is set in a blended reality with humans, witches, and shapeshifters of all kinds, but with a significant lack of acceptance from the humans that results in violence. And I am sucker for fated-mates/insta-connection and you get that in heaps and bounds in Voiceless! Colette’s introduction to the supernatural world added some challenges on top of not being able to effectively communicate with those around her. I enjoyed the overall plot; that there was danger and confrontation and resolution, albeit not nearly as much as I wanted. Voiceless is a short read and things escalate at a fast pace and a resolution is reached just as quickly. As a result, I think we miss out a bit on relationship and character development that we could’ve had if the book was little longer. While this is a RH/why-choose, most, if not all of the spice, is exclusively MF.

Cute
Format: Kindle
Very insta-love, but also cute with likable characters. The plot was good, though lacking in depth. The spice was fairly abrupt and lack-luster. Am enjoyable read, overall.
