woom  OFF 4 Kids' Mountain Bike

The woom air is a fantastic first entry into mountain bike for a younger kid. This model doesn’t have suspension, so if your kid is already hucking off jumps you would probably want that model. But the amazing thing is you can always upgrade the fork! The build quality is fantastic. We had woom 1&2s and the thing we loved still holds true with this modem, it’s super lightweight which is key for a kid who is starting out with a bit of “hike a bike”. The kid wanted me to mention that the seat is comfy, and the shifting is easy, and he loves how lightweight it is. If you have a smaller child, this might not fit until they are 6+. Our son is 44” and he is on top toes as the lowest seat post, so any shorter and you’ll want to wait or look at the woom 3. Love the bike and happy it provides the ability to introduce my fomo son to MTB!!!

My son LOVES this bike. He started with riding with a guardian when he was 4, and he outgrew it very quickly. He could only go about 3-4 miles on it because of the weight and the fact that it was a single gear bike. With the Woom 4, he is able to ride 6-7 miles at least, and has a blast. The bike is extremely light weight, and having front and rear brakes, and a cassette in the rear makes a huge difference. This bike is definitely a step up. The bike is extremely well made - it looks and feels like a premium bike. It is geared towards mountain biking but it does not have a suspension. The bike came mostly assembled in the box, and the instructions to finish setting it up were extremely easy to follow. The tools needed to put it together are included with the bike. My only disappointment is that it is still too small to fit in my bike carrier. I have a Thule Apex XT 4-Bike Hitch Rack, and the bike does not fit on it.

… not for the price. For starters I needed to buy a kickstand separately. The purists will say “but it’s a mountain bike” … yeah, but it’s a kids bike! And for the price, provide the kickstand and let me decide whether to keep it on or not. Additionally, and this will vary from kid to kid … the shifters take a little getting used to, so it’s not really kid friendly from the start. And the gear ratios should include one higher gear. Otherwise solid color and good build.

We've had both the OFF and OFF AIR for our kids (Aged 4 -6) and been so impressed with how these bikes have allowed our kids to progress. With our youngest being on the small end of sizing, the lightweight OFF carbon fork allowed him to climb hills effortlessly, with bigger tires allowing him to comfortably navigate over roots, rocks and curbs. I've only heard him brag about how fast his bike is and how much he loves it.Our daughter has had a OFF AIR for two years and progressed way quicker than her peers. Both kids are ripping down XC bike trails, climbing hills without complaints and figured out the gears near instantly. The woom bikes OFF series are such quality rides, lightweight for the littles to feel energetic on, and just a huge boost to the confidence of riders that need to test unfamiliar terrain - allowing them to keep going and want to get on their bikes again, and again, and again.We've had 4 other high end MTB brands for our youngest, and woom was definitely the best value / quality.

Woom 4 off is a fantastic bicycle because it is lightweight and well suited to the pump track and mountain biking. My son has been biking so much since he received his woom 4 off that we can't get him off of it. Yesterday, we went to the pump track, we're about to leave after a few hours there, and he said "please wait papa, just 10 more times." He has been absolutely ripping it!! In comparison, my older son has a much heavier mountain bike, and he tends to watch (not riding) as much as he rides. Alas, he needs a Woom. As the kids grow up, I encourage Woom to make 27" or xs adult size mountain bikes that are extra lightweight yet provide suspension options, and to eventually expand into the adult market. I wish the Woom Off 4 was already tubeless, because my son doesn't like the trail bumps that much. It's the first upgrade we will make! My brother's friend heard news and has already purchased a woom bike for his child. Should you get one for your child? Yes. Then, sell it when it doesn't fit and get the upgrade!

This is an awesome kids bike , my 7 year old grand daughter loves it. I had the REI bike shop convert it to tubeless before it left the store. And the 18 lb. range makes it one of the lightest on the market, do a comparison and you see.

Its basically a very light mountain bike for a kid. Seems to be the lightest best bike for a young kid to develop skills.

This is our second Woom bike. We love it and will be coming back for the next size when our boy is ready!

Review of Woom OFF 4: This is my child's 4th Woom bicycle. My son is 5.5 years old. He was introduced to a balance bike at about 22 months. We purchased this bicycle during a sale in advance of him being ready for the bike last year. My son is a very capable rider and we ride quite a bit. We ride in an area with a number of hills; so even on the Woom 3, I almost wish he had some gears. I know learning to shift can be challenging even for adults learning to ride. More recently, he began asking for a bicycle more like my mountain bike so we can (in his words), "Go off-roading." which for him consists of riding on any dirt surface lacking grass. However, I had already noticed that riding on gravel surfaces with the smaller/thinner tires of the Woom 3 could be difficult for him. I knew we would probably try to find a small mountain bike next- hence the early purchase. I wanted to wait for him to be a little taller but ended up giving him the bicycle early a few weeks ago. Although he still has some growing to do, he is handling the bicycle just fine. He is excited to have a bicycle with gears, like dads. He has caught on to which shifter does what very quickly. I still have to tip him off when to shift- but if I remind him, he is peddling more than necessary; or point out that he appears to be having a difficult time on a hill, he already knows which shifter to press. The bicycle is built extremely well as with every Woom we have purchased. The packaging was superb, I mean every bit of the bike was well protected. Some things were padded that probably didn't even need padding. I greatly appreciate the effort since it means you don't have to worry about your bike arriving beat up. Assembly is quick and easy although I preferred using my own tools over the provided ones. I also owned a torque-wrench for this application. If you do not have a torque wrench but have experience with working on your bicycle you'll be fine with the tools provided for the initial assembly. I will note that the tools provided don't allow you to loosen the rear wheel for instance. You're only provided with a 4mm and 8mm hex wrench. You will need a hex key wrench set of your own and other tools if you plan on maintaining the bicycle yourself. You need another 6mm wrench to change flats on the rear wheel for instance. I am giving the bicycle 5 stars because it is an incredibly high quality bicycle. I was however disappointed that the rear tire appears to have a slow leak from the factory. I checked for a leak to see if I could patch it but could not find the leak. I ordered more tubes, which I would highly recommend, because walking into a few stores hasn't yielded good results. I also had to adjust the derailleur as the chain kept skipping on the two larger cogs as my son was riding. These 2 relatively small issues aren't deal breakers, but I must mention them. I would be happier if these issues were not present. Now that some stores are carrying Woom products. In the case of the mountain bikes or other bicycles with multiple gears, I would probably recommend seeing if your local Woom dealer has the bike you want in stock. That way you can take it back to them if you run into any issues you can't fix yourself. I don't know if Woom offers maintenance through these retailers for online purchases but that would be great as well even if only for issues found during the initially setup. I hope this review is helpful to anyone considering the Woom OFF 4 for their child. Woom has consistently provided quality bicycles for my family and I am glad they exist. Lastly, I will mention we have actually done a little off roading. This included some short drops, roots and fairly steep descents on a short trail near our home. The bike worked very well and he seemed comfortable. The larger wheels and tires did what they should do- but if you have the extra coin and are dealing with a more advanced rider...the OFF AIR may be something to consider as well.
