Watch your woom grow with your Rider

What if we told you that sizing up from one woom to the next isn’t the only way to accommodate your growing young one? Well, we’d be telling the truth! While we love seeing a kiddo gear up for a brand new bike, there’s plenty of room for your child to grow within their current woom. Our team of product developers and designers have truly thought of everything—from small adjustments like the saddle height, to bigger adjustments such as the Vario stem (which we’ll get to!), your child will always be comfortable when riding their woom.

woom 1 and woom 1 PLUS Adjustments

The woom 1 and woom 1 PLUS may be our smallest bikes, but they have some pretty big features! The innovative bottomless seat tube design allows the saddle to be positioned at just 10 inches above the ground. From there, it can easily be adjusted. Kids as young as 18 months can already start comfortably toddling around on two wheels and mastering balance just as they’re learning to walk.


Because all kids don’t grow at the same rate or start at the same skill level, we offer a hybrid between the woom 1 and woom 2—the woom 1 PLUS. This model is just as adaptable as our other models. While it is a balance bike (no pedals here!), it’s roughly the same size as the woom 2. It’s ideal for bigger children who are just beginning their balancing journey, or those that are a little more advanced. With its SURFBOARD Footrest, your child has a place to rest their feet as they really get into the groove—it’ll feel like they’re gliding on clouds.


*Note: Though the only woom model that comes pre-equipped with the SURFBOARD Footrest is the woom 1 PLUS, the woom 1 has frame bolts where you can mount the SURFBOARD!

woom 2 Adjustments

When adjusting the seat height and adding the SURFBOARD Footrest just don’t cut it anymore, the woom 2 slides in to save the day! The woom 2 is the smallest pedal bike we offer at just 12.3 pounds. Although the woom 2 comes with a bottom bracket, meaning it has crank arms to attach pedals to, many parents choose to gradually transition their young Rider by initially removing the pedals and using it as a balance bike. By simply not installing the pedals on the first go, your child can get the hang of their new bike frame while continuing to master balancing and braking. Once they’re fully ready to take off on their own, you can add the pedals with the provided pedal wrench and watch them ride off!


Aside from adding the pedals when your young one feels ready, there’s another modification you can make: Upgrading the rear wheel. While including a hub brake is legally required for bikes of this size, it’s very common for parents to upgrade the rear wheel themselves (which is completely legal). By replacing the coaster hub with the woom 2 FREEWHEEL Kit, your kiddo will be able to freely back pedal without engaging the brake. This also allows your child to experience less pedal resistance. Freewheels are the norm on larger woom bikes, helping to familiarize your child with their next woom before they’re ready to take it for a test ride.

woom ORIGINAL Steering Limiter

All of our smaller bikes (woom 1, woom 1 PLUS, woom 2, and woom 3) come with a woom ORIGINAL Steering Limiter. Designed to prevent accidental overturning, this small but important piece has an intentional breakaway feature. Once your Rider has outgrown the need for the steering limiter, it will naturally break away. No worries if you’d like to replace it though (perhaps for your next young Rider), you can find a spare here!

Hand Brakes

One of the most important parts of a bicycle is its hand brakes. woom provides brakes that can be adjusted to meet the Rider where they’re at. Kid’s hands come in a wide range of sizes and each child grows at their own pace. To account for this, all of our smaller models (woom 1-woom 3) include an easy-to-use reach adjustment knob. This knob determines how far away the brake lever is from the handlebars.


There’s more! woom bikes feature a barrel adjuster which can alter the brake lever tension to account for changes in grip strength. The brake levers themselves can also be rotated up or down so that the Rider can reach them from a comfortable, neutral position.

Seatpost Adjustment

The most straightforward way to alter your woom bike is of course raising the seatpost. Raising the seat is a cinch on our ORIGINAL models, as they all come equipped with a quick release seatpost clamp. The only thing you have to keep an eye out for is the minimum insertion point—you don’t want to go past this!


Brand new Riders should be able to comfortably place their feet flush on the ground while seated. More experienced Riders can extend the seat upward so just their tiptoes touch when seated. This higher seat position will allow for greater leg extension and more efficiency when pedaling.

Handlebar Adjustments

Although the woom 1 riser handlebars aren't adjustable, all other handlebars in our lineup are. The woom 1 PLUS, woom 2, and woom 3 all come with BMX-style high-rise handlebars that can be easily adjusted to accommodate growth. Simply tilt the handlebars forward or backward by loosening the bolts on the front of the steak. The ideal positioning would allow the Rider to be slightly leaning forward with their arms coming downward at a 40-60 degree angle.


Our larger bikes (woom 4, woom 5, and woom 6) have an ingenious Vario stem design (we said we’d get to this!) that allows for even more handlebar adjustability. By simply loosening two bolts, the Vario stem allows the handlebars to unfold into higher or further positions so your growing Rider can always find a comfortable position. To find out more about adjusting your Vario stem, we have a video!

Gear Adjustments

Along with the Vario stem, the larger woom models (woom 4- woom 6) offer another major feature which changes the way children use their bikes—gears! As kids transition from a single-speed bike to one with gears, it’s likely they won’t initially use the full range of gear options. However, as they grow stronger and more confident (which they will!), they’ll begin to explore how the different gears work—lower gears for hills and higher gears for flat ground or downhill terrain.

woom OFF and OFF AIR

And with the mention of exploring and trying out new types of terrain, your Rider may be looking for even more adventure. If your kiddo is looking to explore off-road, look no further than the woom OFF and woom OFF AIR. Outfitted with trigger shifter, hydraulic disc brakes, and an optional suspension fork—these bikes are the perfect child-friendly introduction to mountain biking. These are available starting with our 20-inch models (woom OFF 4 and woom OFF AIR 4, respectively).

Whether hopping aboard a woom ORIGINAL, woom OFF, woom OFF AIR, or woom UP, your Rider will always have a little extra wiggle room thanks to our trademark kink in the top tube of the bike frames. By reducing the necessary standover height, we’ve expanded the growth range of each bike and have allowed Riders to gain confidence hopping on and off their bikes.


A kid’s bicycle is a means for personal growth—it’s only fitting that their bike can adapt to their ever-changing needs. When a child has a well-adjusted bike that fits them comfortably, the sky’s the limit! Whether it’s adjusting brake levers, the seatpost, or handlebars—the ability to modify your child’s bike as they grow is vital. No matter where your young one’s cycling journey takes them, woom is here to grow with them along the way.
