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.

Perfect for travel. Sturdy and will keep your items safe.
Color: Cloud White, Size: 8"W, Color: Cloud White, Size: 8"W
This was a galentines gift for a gift exchange. It comes with multiple compartments that are removable and can hold any type of jewelry from studs to necklaces, rings and bracelets. Any solid bracelet takes some maneuvering to hold. This is semi customizable to fit your needs and will house most jewelry items. The zipper does get stuck a bit but is a strong thick zipper and not super flimsy. The inserts on the sides can be removed, however, the ring inserts seem to be glued down. Bigger jewelry or chunky jewelry pieces may not fit well in this travel case. All in all it can hold quite a bit, the size is compact and perfect for travel and it’s a handy organizer for jewelry.

Economical Storage Solution

I needed a storage solution for some pieces that I wanted to keep in a small safe. This works great. Also, perfect size for travel. You will not be able to use all of the earring holes for adult size jewlery. But that’s okay. For the price point, you can buy multiple.  Tangle resistance: Price!

My fave ever
I bought this to travel for a summer camp and still use it, two years later! It is now my everyday jewelry container. The gold clasp has held up well and closes well. Very easy to use and structurally sound! I love the color and overall vibe of it too- very straight forward. I use the top portion for long earrings, so know if you do that, it can be finnicky, if you have fun or funky shaped earrings- so just know they may get caught but it's such an easy fix. I would say it is about the size of half of an American Girl doll. Maybe around the size of half a goose.

Love this! Sturdy and elegant
I have a small selection of jewelry pieces I wear but I needed something that would keep them all together in one place. This jewelry box is fantastic! And It fits two pairs of sunglasses on the bottom compartment. I like that there’s a little tab to help pull up the top part. It was actually a bit bigger than expected which is a good thing. And still small enough for traveling. The necklace tabs are sturdy and hold them in place. I’m very satisfied with my purchase.
