woom OFF 4

A very nice and good looking bike. On the plus side: balanced component selection, very good fit, upright position and proper MTB geometry, safe grips, nice saddle, thick and long chainstay protection, external routing of all the cables (thank you!), proper drivetrain, good grippy but not overly sharp pedals, gearing is fine for the age, high quality wheels that spin freely and can easily carry an adult, thru axles. There are some considerable downsides as well though. Components are a bit of a hit and miss. On almost a thousand euro bike I would not like to see Promax brakes that usually start leaking in about a year and are impossible to find service parts for. A cheap Sunrace cassette is used instead of a higher quality sram or shimano one; chain is also a cheap KMC that on an adult bike wears out in a couple of months (less relevant for kids, but still a sram chain would be appreciated). I'd also expect a UDH hanger from a mountain bike in 2026, but here we have a custom one, and axle threads are cut directly in the frame drop out - a very expensive repair should you damage them. Fork - it is carbon, cool! But it is a 1 inch steerer tube (not 1 1/8 as you find on most bikes), so if your kid wanted to put her cool colorful headset spacers and a top cap there - too bad, it won't fit. My daughter got pretty upset over this. Why not just put a normal steerer there, 1/8 of an inch is really not a lot and will fit the headset. BTW, you cannot just use any stem if you want to adjust the fit. Also, expander plug is glued in , so you cannot replace it, cannot cut the steerer, it is already as short as it can be. On top of that, the quality of the fork is questionable - when I started adjusting the front brake, I found that the bolts were barely moving. I found damaged threads both on the bolts and in the fork brake mounts. I had to chase and clean the threads in the fork and replace the bolts to get everything to move freely. Then there is build quality - all bolts are overly tight and / or too strong threadlock is used. Headset - over tightened and assembled bone dry, I had to disassemble, grease and re-adjust it, also removing strong threadlock from the bolts. Both thru axles - bone dry, had to grease them. Derailleur hanger - bent, I had to use an alignment tool to straighten it before I could achieve proper shifting. The box says it should have some stickers, but they were missing, bummer. Overall, nicely engineered, cool looking and great riding bike. But with poor build quality and some questionable component choices. The weight is also a bit of a disappointment, I'd expected a 20" rigid bike to be a bit lighter. It has an 8mm and 4mm hex keys included, implying that this is enough to build the bike out of the box. Well, it is not, not nearly. I had to use some very specific tools and grease to make it into a proper bike. But my daughter is really happy riding it, so I guess, it offsets the issues somewhat

I would have given it 5 stars, however, it was missing the fasteners to put on the two reflectors. I called Customer Service & they are sending me the reflector kit. Otherwise, my Grandson is thrilled with his new bike!

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

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!

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

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.

My boy belongs to the Puerto Rico Cycling Federation since the Balance Bicycle and when he reached the age when the routes began to be more technical, a bicycle that met the competitive level that adults have in terms of what is a bicycle for participating in events versus a recreational bike and at the same time that was light, because other well-known brands have bicycles with those specifications but the weight can sometimes be even greater than the weight of the child, that is where in the search we arrived at Woom. Knowing the story of how this bike originated and its components, we no longer had to look for anything else. This season my boy has had successful results in each of the events he has presented and he is undefeated. Other parents have already asked us to test the bike and have sent us to buy the bike for their children, since they are not sold here on the island.

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.

Arrived promptly with minimal but effective packaging. Minimal assembly needed - bike was built up better than complete bikes I’ve previously purchased costing $5k+. After a couple minor adjustments and 30 minutes we were ready to rip… so excited, thank you.
