20 Best Bmx Bikes For Dirt Jumping (2023 Updated)

Very very pleased with this bike, my 9 year old son loves it and the way OutdoorToys. com packaged and sent the bike was really great too. Minimal assembly required, took my oldest son less than half hour to fit it up.

My 9 year old was on pedals with his previous bike, we bought this bike at Christmas and he is already riding this bike with no pedals and very confidently, the braking and overall structure of the bike is really good too, also the bike is not too heavy and very manageable for him, the seat height adjustment is very useful and good for him too.

My son wants to ride his bike every day now and he uses the bike for bike it club after school as well. My son has Autism and Adhd and I chose this bike because of the detailed description from OutdoorToys.

com explaining that the bike is designed also in mind for Children with special needs, in terms of the braking, pedals etc. Don’t hesitate to bike this bike for your child, it’s well worth the money, and delivery from OutdoorToys.

com is exceptional along with the packaging. I don’t ever do reviews and I am an independent customer so giving yiu review from my own personal experience and having own the bike for my son. Thank you OutdoorToys.

In and of itself the tire is very good. It’s heavy which I don’t really like. This could be mitigated by making the tire in a 2. 3, but Maxxis doesn’t make this tire in a 2. 3. If it came tubeless that is another way to cut down the weight, but I don’t think it is tubeless.

What I do like about the tire is its durability, cushion and grip. The thing can take a beating but impacts aren’t as atrocious as they can be with a 2. 1. Does good for the wrists. The rollability is decent but not the best.

I’d like to see less “negative space”, that is, to say conversely, more “knob surface”, as I think this would help with the rollability. But I’m not a tire engineer. I’m just kinda guessing here. Overall it’s a great tire.

wish they could shave the weight and make smoother. Would help with instantaneous momentum increases and rollability, i. e. would strain my quads a little less. This could all probably be mitigated by using a DTH but the DTH has been out in 2.

3 for about 3-6 months now. That’s half a year of my life. fwiw. Pick up the pace Maxxis.

This is a great tire. I meant to order the larger ones, but these were so light that I decided to keep them. This tire reminds me somewhat of an old “Snakebelly” BMX tire, or a park/street tire, which of course is exactly what it is.

I weighed both at 554 grams on a triple beam scale. Supple casing, smooth rolling. More expensive tires are lighter and the casing is higher quality so the tire is more supple. A more supple tire rolls over bumps more smoothly as opposed to a cheaper casing having more tendency to bounce off the object it impacts.

I’m running these at 40 psi because rolling resistance can be somewhat counterintuitive. High pressure may not deliver a hugely higher speed, but will give a bumpier ride for sure.

Got the 120tpi in 26×2. 3 for use on my Motiv Sherpa e-assist cargo bike. Replaced a worn set of Kenda SB8s, difference is night and day. The DTH is very fast, has great traction, and unrivaled comfort.

The way they corner reminds me of a motorcycle street race tire, and yet they still perform well on fire roads and jeep trails. I couldn’t be happier with the gumwall DTH tires, they are magnificent.

Or should I say, “Maxxnificent”!.

Being so lightweight, I had no problem choosing this for my 5 y/o dipping his toes into BMX. It seems well built, is even lighter than expected, and he says it’s comfortable on the head. Of course, the dark, matte finish makes sure it also passes the all important style test.

Is this something you’d wear on a downhill track? Probably not. But for a child on a BMX track, I feel better knowing he has a quality Bell helmet on, and is much better protected, than if he was wearing an open face helmet.

Overall, great value for money. A known, proven brand. And a lightweight, but safe, helmet. Couldn’t ask for more. Can’t complain about bicyclesonline either. After a small issue getting the site to work (probably me), I was contacted by a helpful staff member, who fixed everything up in a blink.

I mostly ride trails but spending a bit more time in lift access gravity parks (Thredbo MTB) and wanted a little more protection. The Sanction was a good option for the $. Understanding that is a simple Helmut (no MIPS etc).

Im a average size guy and wear a Medium no worries. I wear googles with the lid too no issues. Great for the price.

Previously had Bontragger stock MTB tires that came with my Trek X-Caliber 7. I commute 16k/daily on urban streets in Japan. Been rolling on them for about a month, and I really like them! Obviously, much smoother and quieter on asphalt than standard MTB tires.

I’d def recommend them if you ride street and want something fast, yet tactile and smooth.

Switched a mountain bike to a street and trail bike. These tires fit the project. Easy to install. Great ride and quiet, smooth. Real nice. They look great also

Perfect bike for my sons first BMX. I had no knowledge of what to buy, but this was perfect. Boxes ticked.

The bike looks cool. Ours was missing a brake pad in the back which we didn’t realize until today when my son dropped his bike, as kids do, and the front brake lever just broke off of the handlebar. We took it to get fixed and the guy at the shop said they’re not great quality, they’re just plastic.

I got them replaced and had a brake pad added. So basically, I spent $40 to make a brand new bike useable. I think for a bike that’s above $100 it should be better quality. Especially with the safety of children at stake.

Get on! Tough to beat this great kids Kent Ambush 20″ BMX bike when you consider the price. Being stuck at home, our 7 year old son has been out riding his bike around our culdesac more than ever before.

His 16″ bike was just too small so we decided to upgrade to a 20″ BMX style bike. Glad we went with the Kent Ambush as it is a great all-around bike for the price (exceptional value). Our son loves the Black/Red/White color combo.

Everything is easily adjustable with basic wrench sets so you can size it properly for your kid. Seat height, handle bar tilt, and brakes adjust easily to ensure comfort and safety. The chain guard and kickstand are nice features to protect your kid and the bike.

Set up was fairly easy. You only have to “install” (or connect) the front tire, handle bars, bike seat, pedals (foot pads only) and front brakes (pulling cable taut and pad alignment with wheel/rim).

You will also have to add air to the tires so be sure you have some type of bike pump or compressor (with tool for tires). The most difficult part of set up is connecting the front brakes, ensuring the brake cable is pulled taut so the brake pads stop the bike.

Probably helps to have a 2nd person help with that step but I was able to do it myself. Should only take a 1/2 hour or so to get set up. Our son has not stopped riding his new bike, riding off curbs and down steps, and racing his friends, things he couldn’t do on his smaller bike.

Note that he rides with a friend who has a $300 Haro BMX bike. Tough to tell the difference the way the kids use them, other than the weight of the bike itself if you have to load it into a car. The more expensive bikes are typically much lighter.

But at this age (7-8), that doesn’t matter. I highly recommend this bike as a great 20″ starter BMX!! Get it!.

My son entered the Winter Nationals as a 13 Novice on his Kent Ambush. He loves the handling. He made the Mains all three days, (beating several sponsored riders on bikes between $400 and $1,000 with one exceeding $2,000.

) I put another brand’s pads on it for safety. Bike 812. Watch the races on YouTube (2021 Winter Nationals) to see a Kent Ambush beating numerous “high end” aluminum and carbon fiber bikes. True, the Kent is a tiny bit heavier than ideal and it needed a bigger front sprocket than it came with, but essentially it’s ready to race and the handling isn’t twitchy.

Pretty close to a race bike for under $100. My son wants a sponsorship from Kent and to stay on Kent products.

Good price the only place that had it online at this price. Fast shipping handling time just ok took a few days to ship. But not horrible. Came in great condition very pleased. Saved this site to my favorites 4 sure.

The perfect move from 20.. is 22. Especially if you hit 50 and the bmx dream still alive. Thank guys! 👊🏾

Super quick postage to South Australia. Great price and free shipping.

Upzy was fast and I had no problems with my order. Trike came much faster than I expected, and arrived well packaged and in good shape. Price was cheaper than anywhere else I could find, and the TRIKE is awesome! The instructions are pretty simplistic and I recommend watching the youtube assembly video by RBR, it was fantastic.

I used the tools that came with the JC-26X to assemble and they worked well, they are also my foundation of ride along tools for the trike when I am riding away from my house. Get a tire pump with a gauge with presta valve fill ability! Trikes tire pressure is more adjustable that your old mountain or bmx bike, (you cannot, with most trike tires, tell the pressure with the old squeeze method) and you will need to experiment with the tire pressure that combines the best feel for your conditions, mine are at 60 PSI currently and its a nice mix of vibration absorption and sharp handling.

Tire pressure ranges at 37 PSI to 72 PSI. It took me 3 days to fully build. The first day I rode it by 9PM after starting at 2PM with assembly. But I didn’t install any of the extra’s. Do not overly loosen the clip pedals tensioner, or the threaded plate can pop off and I have not been able to get it back on yet, after 5 hours or messing with it.

I had another set of clip pedals thankfully! Highly recommend getting shoes that clip to the pedals, much safer. You otherwise run the risk of running over your foot/feet/legs with the front tires. My dad has done it on his trike and said it hurt ALOT and he wasn’t going fast.

Top speed so far is 28. 8 MPH. Careful with the steering at speed it is really sensitive.

The trike arrived within a few days after it was shipped. It took about two weeks altogether. I ordered the milky white color. I expected more after watching the reviews raving about the paint jobs. Mine had a run and sag in the paint albeit in an inconspicuous place.

What really bothered me was the scratches down to the metal on the cross piece in plain view. Good thing they send touch up paint. Thankfully there were no dents in the aluminum frame. The scratches could have been because of UPS throwing the package around, something I sometimes think they do deliberately.

But I can’t be sure as I was in such a hurry to unbox the unit I didn’t take notice of damaged packing materials. Other than the paint issues, I think the quality of the trike is quite good. I did order the chain adjuster for multiple riders from the USA dealer of Performance and made the mistake of ordering the extra chain, thinking it was a complete chain.

For 30 extra dollars, it was a foot of chain that I didn’t need, and to add insult to injury, a mismatched connecting link. So if you order the chain adjuster, don’t order it with the “chain”. I also noticed the rear tire wasn’t seated quite right on the bead, so deflated it and found the tube was pinched.

Assembly instructions are weak, but a u-tube search will give you an excellent guide.

Everything about this purchase was top notch. From the order, to the confirmation, to the expected delivery date, to the follow up, were all first rate. The product arrived a few days ahead of schedule and even though there was an intermediary vendor involved, It was smooth as silk.

The trike I purchased is beautiful and well made and partially assembled. The finish assembly instructions which came with the product need some work (OK, a lot of work). I would not hesitate to purchase here again.

The trike itself had a crushed derailleur mount (the screw was driven too hard), but as another reviewer mentioned, a replacement came in the box of parts. I, too had the extra bar in the kit and it wasn’t until after I had spent almost an hour trying to set the toe in, I realized the extra bar is exactly for that.

ICE uses one in their toe in video on YT. Mine also has an independent boom clamp sleeve which fits over the end of the boom frame. Terra Cycle makes some quick release boom clamps which will fit that sleeve nicely.

I put one front fender on and didn’t like the look, so I took it back off. Now I’m looking for a mounting bar to clamp to the fender mount for my phone and stuff. I may just have to make one because I can’t find one.

Overall, I’m happy as a pig in **it about this trike. I have a well made, fast trike for half the price of the name brands.

Frame and geometry The Marin San Quentin offers modern aggressive geometry. The relatively steep seat angle really helps with climbs, while the slack head angle helps you descend with confidence. The first thing I noticed when I got mine was how much the frame sparkled in the sun.

I am 11 years old, 150cm tall (pretty short) and around 38kg (very light) so I got the small frame size. I think the reach is the right size for me but bigger people might feel cramped. One thing I think Marin should change in terms of geometry is the low stack which puts more of your weight over the front and can give you the feeling of going over the bars.

You can make this better though by putting all the spacers underneath the stem. I also think Marin should change the chainstay length over the different sizes to make every size feel equally as playful and the same.

The frame is about as compliant as most other aluminum hardtails but the tires kind of help with smoothing everything out. I like how it has a tapered headtube and a threaded bottom bracket. There is room for a large water bottle in the front triangle but there are no other bolts to store anything else.

The frame also has mounts for a chain guide and a bashguard. It is good that it has chainstay protection, but in the first week of riding the chain had already made a hole in it. Cable routing is okay but not amazing.

Components For the price, you get pretty good specs: Fork Instead of smoothly going through its travel, the Rockshox Recon fork kind of steps through it. Out of the five clicks of rebound the slowest two are pretty much unusable because of how ridiculously slow they are although 130mm of travel is the perfect amount, not too much but not too little.

But apart from that, the fork is good for the price. Shifter and derailleur The Shimano Deore shifter feels good and the derailleur shifts smoothly. Brakes The 2 piston hydraulic brakes feel good for me but someone heavier will probably need more power.

Dropper post The dropper post has had no problems so far and works pretty well, although the cable for it is far too long. Tires A big thing that I think I will need to upgrade are the tires. The tires are wire bead so you can’t run them tubeless, they are very heavy, they have good braking traction but are a bit unpredictable when cornering, the carcass is pretty flexible which smoothes out the bumps but it makes the tire want to roll a lot.

Rotors On bicycles online it says that the front rotor is 180mm and the rear is 160mm but on my bike it came with 180mm front and rear. I’m not sure if it was just my bike that came with a bigger rear rotor, but bigger rotors have more stopping power.

The cranks and bottom bracket are not listed on bicycles online’s website but they are both samox. Every other component works really well and hasn’t had any problems. Conclusion Most of the problems with this bike are so small that I almost forgot some of them.

The only real complaint is the tires and the stack height. Once you’re on the trails with this bike you just forget about all the little things and ride. The Marin San Quentin feels like a hardtail should feel.

It teaches you valuable skills like line choice and jumping. I recommend this bike for anyone who wants an aggressive hardtail at a reasonable price and who wants to push their bike hard.

Im really chuffed with the new bike. Glad I went with this Marin from bicycles online as it was a big call for me to spend this much. Coming from a beginner XC hardtail this bike feels insane and leaps and bounds better.

I honestly love this bike so much. I was in between sizes so went with the smaller size of the two which was choosing the large for me and that’s definitely the right choice if you want to be playful and poppy instead of big planted feel.

In terms of building the bike it was pretty easy, I’m really happy that the bike was packaged with reusable/recyclable materials: it pretty much came with 25 velcro frame straps for all the packless riding situations.

I did however change the brakes straight away as I had some better ones and wasn’t too keen on the beginner Shimano brakes this bike came with, although they do seem far better than any tektro brakes.

The bike coming with the lil torque wrench and other tools was really nice and the plastic pedals it came with are actually so good I might run them on my BMX bike (put my own pedals on this bike straight away).

It didn’t come with a shock pump though so you’ll need to get one to set up your sag and all that goodness. Overall I have 2 minor downsides: firstly the dropper cable came way too long, I had to cut about 250mm off to make it look neat.

Secondly, the rear brake cable came out of the frame on the left side when it would have been better to come out the right side with the dropper so you can run them together. When I changed my brakes I fixed this, but it could be quite annoying to anyone who enjoys a tidy cockpit.

Both of these things are easy easy fixes tho, and Shimano brakes are real easy to bleed if you swap the brake hose to the other outlet from the frame. So overall bike is fully sick 10/10 would recommend, and getting it from bicycles online is definitely worth it for the better experience (and crazy fast shipping-my bike got to me in QLD the day after dispatch).
