From Woom:

The woom 4 introduces children aged six years to the world of gear-shifting. The bike's seven speeds in combination with the easy-to-operate twist shifter expand the bike's range of use and increase the child's mobility. Whether they want to ride their bikes into the woods or up hills – the new-found freedom of gears make longer adventures on two wheels child's play.

Lightweight Aluminum Frame

Geometrically designed for kids six and up and forged of sturdy superlight aluminum, the frame is the heart of the bike. The low standover makes getting on and off the bike easy. The light weight means your Rider can go further, faster, and higher than ever before.

Safety-Focused Brakes

With climbing big hills come big descents. The woom 4 comes with independently operated front and rear V-brakes to ensure that whether your Rider is bombing down that big hill they conquered or making their first forays off the pavement, they can always control the bike safely. The two V-Brakes are easy to operate thanks to their ergonomically adapted brake levers with reach adjustability.

woom Crank

The crank length and distance between the pedals are ergonomically adapted to fit children's bodies. This results in an optimal stance and very natural movements. And thanks to the chain guard those days of getting your pant leg caught are over!

Ergonomic Contact Points

Comfort is very important to the riding experience and that's why the contact points on our bike are made specifically for kids. The saddle is designed to accommodate a young child's anatomy and biomechanics. The grips are ergonomically designed for kids' hands. The pedals are durable, reflective, and slip-resistant. 

Quick-Release Seatpost Clamp

The quick-release seatpost clamp offers a simple, quick and tool-free way to adjust the saddle height. It's even easy enough to be operated by children. On your pedals, ready, go!

High-Quality Tires

The high-quality Schwalbe Little Joe tires provide plenty of traction and durability. The 20” diameter, 1.4″ width tires allow your Rider to traverse both pavement and dirt with plenty of control. The reflective sidewalls of the tires give them further visibility on darker rides.

Tailor-Made Wheels

The woom SOOPA DOOPA HOOPS are specially designed for the child-specific geometry on the woom 4 and feature our smooth, frictionless hubs and double-walled rims. The rims come with a 20 stainless steel spoke design to offer a perfect balance of strength and lightweight.

Adjustable Vario Stem

Kids grow fast and need a bike that adapts to them. The Vario stem is constructed of lightweight forged aluminum, making it quickly and easily adjustable. Our Vario stem allows your Rider to optimize their riding position as they become taller. By extending the reach of the handlebars, the life of the bike is also extended.

Really Helpful and Easier to Use Than I Expected
Format: Paperback
I bought the APA 7th Edition manual for my college research papers, and it’s been a lifesaver. Compared to the older edition, this one feels much clearer and way easier to navigate. The full-color layout and the examples throughout really help when I’m stuck on how to format citations or references. I especially appreciate the new sections tailored for students like me—it’s not just for professional writers anymore. Plus, the tips on inclusive language made me think more carefully about how I write. It’s definitely a dense read if you try to go cover-to-cover, but as a reference book, it’s super practical. The only downside is that it’s a bit pricey, but for the quality and how often I use it, it’s totally worth it. If you’re in school or need to write APA-style papers regularly, I’d recommend grabbing this manual. It makes the whole process less stressful.

Vast improvement in substance and organization; a few downsides
Format: Spiral-bound, Format: Spiral-bound
Among my other writing-related pursuits, I edit PhDs. This APA 7 manual is a big improvement over earlier APA editions. The primary purpose of any edition is to update the APA standards. This manual is packed with content and examples that were IMO long overdue. For instance, there are templates to show the order of data for Reference entries, and there are side-by-side examples of Reference and in-text citations. I ordered the wire-bound version because it works well in any workspace (i.e., you can easily fold the book in half or leave it wide open. The chapters are divided by tabs, with the ToC (table of contents) for that chapter printed on the tab. Compared to earlier versions, the font is smaller, but it remains highly readable. The margins are wide enough for notes. There are several downsides to the manual that I hope will be resolved in the next edition: (a) For such a large manual, the cover on the wirebound copy is both too short and relatively flimsy. It is too short because it is only the width of the pages. It does not extend over the tabs. It is too flimsy because it is the same weight as earlier and less substantial manuals. (b) There is no tab for the index. (c) Although the font in the chapters is a sufficient size, the font in the index is much smaller and the index pages are crowded; there is less room in the margins for taking notes. I dealt with the cover-related problems by cutting up a transparent binder/page sleeve for the front, back, and spine of the cover, and by creating my own tab for the index. There's nothing to be done for the index font except to live with it. You can get the gist of what I've reported here by looking at the pictures I've attached.
