I’ve spent three weeks with a brand-new Haro Klunkerson. Is it any good?
I discovered the Haro Klunkerson quite by accident. I hadn’t heard of it before, nor did I find any news of its launch. And there’s a bloody good reason for that—one Google search will show you why.
At time of my purchase, April of 2024, there was nothing online about the Haro Klunkerson but retailers. No reviews. No social media. I think I found one old Reddit post with three short comments. But that’s it.
Now, you want to Google the more popular State Klunker, or bikes like the Surly Lowside, and you’ll find some decent articles and socials.
But up until now, nothing but online retailers came up when I searched for the Klunkerson—all recycling the same marketing material doled out by Haro, and sometimes links to this fun YouTube video. It was as though the cycling community had never heard of it.
So I’m going to give you the gift nobody gave me. A review of the Haro Klunkerson. Let’s take a look at some key specs first.

Klunkerson Specs
FRAME | Full chromoly Klunker style frame with 3/8″ dropouts, internal head tube and disc brake tabs | RIMS | 27.5″ Alloy Double Wall, 36H double wall alloy rims |
FORK | Full chromoly disc fork w/tapered 1-1/8″-1.5″ threadless steerer tube | BRAKES | Promax DSK-300 Mechanical disc brake w/160mm rotors (front & rear); Promax BL42 two-finger |
CRANK | Haro Baseline 3-pc chromoly 8 spline 175mm | HANDLEBAR | Full chromoly Klunkerson bars 4.5″ |

TIRES | Kenda “Kruiser” 27.5 x 2.4″ | HEADSET | 1 1/8″ X 1.5″ sealed bearing |
There’s more than the above—but you can find that easily at Harobikes.com. I want to talk riding impressions. And whether or not I’m glad I laid down the cash for this thing.

Fit
My biggest concern was fit—I’m 6’2″ and one of the reasons I wanted a Klunker is to have a relatively comfortable cruiser to bomb around on. Was this thing gonna kill my knees, back or butt? Actually, no. While I’m likely at the top end of a comfortable height for this bike, and it took a week or fiddling with the seat to get it perfect, I’m pretty happy with the comfort.
I asked the guy at the bike shop how you fit a Klunker and he just shrugged. “You really don’t.”
It’s true—it’s a one-size-fits most. If you’re over 6’3″, don’t buy this online. You’re going to want to ride it first. But anyone between about 5’6″ and my height should be fine.
At 175mm, the crank arms are on the long side—so I’m not sure how much customization you can do on this, fitwise. I think the stock 39T chainring is about as large as you’ll be able to go too. I’m toying with the idea of different handlebars, to raise them up a nudge. (But I probably won’t bother.)
On this bike, I can’t fully extend my legs while riding in a seated position—if this is going to annoy you, take it for an extra long test ride. And while the seat looks amazing, it’s not exactly plush. Maybe this is the old man in me… but would it have killed them to add a 1/4-inch of memory foam?
I prefer to ride this Klunker standing up anyway. Kinda the way it was meant to be ridden.

Ride
Speaking of the ride—what’s it like? Well, it’s simple. And fun. And hard. And harrowing. Let me explain.
In a world of e-bikes and carbon road racers, this is a throwback to your old BMX you left outside one day and never saw again. It runs 39/17 gearing—which is about a 2.3:1 ratio. So it’s not a bad cruiser—I rode 10 kilometres home from the bike shop, in moderately hilly terrain, and it took me about 35 minutes (total), averaging about 17 km/h.
However, I am leaning towards wishing it had something closer to a 2:1 ratio. Some of those uphills were tough, and if you take it into the trails, steep dirt might finish you. Plus, I bought it to be a wheelie machine and a lower gear ratio would make that easier.
After a 30- or 45-minute ride, I’m pretty sweaty. And there are a few times I’ve thought about changing my route… but then the hills stop me. Maybe I just need to get in better shape.
But it is fun. I get compliments all the time. And the wide handlebars, 27.5″ knobby tires and short wheelbase means it responds quickly and well. Case in point, I took it on a dirt path, headed towards a jump, chickened out and swerved around the kicker with ease… then almost hit a cement abutment and swerved back.
What I’m saying is—this bike is like an extension of your body. Point it and it goes.
I found the mechanical disc brakes more than adequate, even though I’m accustomed to hydraulics on my other bike. Big rear-wheel skids and front-wheel endos are easy. Plus, I like the simplicity and light weight of mechanicals. Original Klunkers barely had functioning brakes at all—this is an upgrade.
The 2.4″ knobbies are meant for dirt. If you don’t plan on riding trails at all, you may want to swap them out. I plan on spending some time on dirt so I’m happy with them. But they are trail-oriented, and combined with the tall gearing… well, you’ll get your exercise.

Value
This bike pretty pricey, for a Klunker. It’s about $300 more than the stylish State Klunker—although it’s considerably better spec’ed than the State. I got a sweet deal from Ride On Cycles and paid 30% less than MSRP. So at that dollar-figure, the value is killer. At the full $959 CAD pricing? Well, one might expect at least hydraulic brakes.
A Klunker is very much an emotional purchase. And this bike called out to me. Others will see it as an overpriced novelty bike. Only you can decide.
Good Stuff
Let’s break this down by bullet point.
- Looks amazing—seriously stylish. I am constantly getting compliments.
- Comfortable to ride, even for someone who is 6’2″
- Responsive and decent on the dirt
- Wheelies, bunny-hops, endos? Yep!
- Full chromoly frame and fork
- Tapered head
- High-quality components throughout, including disc brakes
Room For Improvement?
I would have done these things differently:
- Gear ratio is too tall—this bike needs a 2:1 for wheelies and climbing
- Handlebars too low-profile? Would open the dimensions up to taller riders with a bit more rise
- More padding in the seat would be appreciated
- Crank quite long at 175mm—shorter arms would allow for more custom gearing choices

State Klunker vs. Haro Klunkerson
State’s popular and excellent-looking Klunker is the closest competitor. But how do the two compare?
Spec | State Klunker | Haro Klunkerson |
PRICE | $584 (CAD) | $954 (CAD) |
FRAME | Hi tensile steel | Full chromoly Klunker style frame with 3/8″ dropouts, internal head tube and disc brake tabs |
FORK | Hi tensile steel tIG-Welded 26” Unicrown | Full chromoly disc fork w/tapered 1-1/8″-1.5″ threadless steerer tube |
GEARING | 42/22 | 39/17 |
TIRES | Wtb Vigilante 27.5” x 2.3” | Kenda “Kruiser” 27.5 x 2.4″ |
RIMS | 27.5” Aluminum 36H | 27.5″ Alloy Double Wall, 36H double wall alloy rims |
BRAKES | Coaster Brake | Promax DSK-300 Mechanical disc brake w/160mm rotors (front & rear); Promax BL42 two-finger |
CRANK | Alloy Crank Arm Length: 170mm | Haro Baseline 3-pc chromoly 8 spline 175mm |
STEM | Aluminum bmX-style Clamp diameter: 22.2mm Length: 50mm | Haro Lineage CNC top load, 52mm reach |

Final Thoughts
I’m very happy with the Haro Klunkerson. It’s fun and simple—no gears, no suspension, no lithium-ion batteries to recharge. And because of those facts, a 45-minute fun ride in my neighbourhood also doubles as a workout! (Especially in the hilly city where I live.)
It’s not likely going to be your only bike though—the single-speed is limiting and the riding dynamics mean it’s better suited to fast laps on the track, cruises to the pub or beach or messing around at the park… not a serious day of riding. So you’ll want to keep your road or mountain bike in the garage if you still hope to keep multi-hour tours on the menu.
But it’s delivered all I hoped it would. Not everybody is going to “get” this bike, and it’s not designed to be a crowd pleaser. But for a Klunker like me, or you, it’s just about perfect.
Just try to find it on sale.

Thank you so much for the review.
Excellent review! I recently purchased the Haro after looking at the State & Surly (even thought about building up an old Schwinn). My decision was made with the chromoly F/F & disc brakes. I grew up in the early 80’s riding ABA BMX. Starting out with hi-tens frames & coaster brakes and breaking both on more than one occasion. I currently mostly ride 24” & 26” BMX bikes and some occasional light MTB action. Having been recently bitten by the klunker bug within the last year, the search commenced. As a small guy (5’7” 175 lbs) the bike fit me very well. The bars are a tad low for my liking, I’ll be replacing those with a SE big honking cruiser bars. Agree with the seat leaving a little bit to be desired, but that’s also an easy upgrade. There are a few other parts I intend to replace mostly for cosmetic reasons. Overall the bike scratches my klunker itch without having to worry about breaking it when I decide to channel my inner teenage self. Haro really should advertise this bike a little better, it would fill a niche for a lot of folks that want a tough, reliable, low-maintenance single speed.
Thanks! I totally agree. It was incredible to me that such an awesome bike is flying under the radar. And I too may raise the handlebars, they look cool but are a little low-profile for me.
I can email some pics and a parts list of my modded Klunkerson to add to your site. Tried your contact link but it bounces back “undefined.” Just let me know.
Hey! Sorry, I just realized that form is broken. Would love to see them. I will fix the form ASAP and get back to you when I do. Thanks so much for reading and commenting. (Trying to find the time to deliver on my promises here… website is suddenly getting traffic, lol)

I’ve been seriously thinking about investing in the avenger 27.5 by we the people. A higher end and more expensive klunker than this haro, which i only just learned about. Looking for any thoughts and hopefully help with a tie breaker. Thanks!
I think between the two it’s an emotional purchase. Spec-wise, they’re quite similar in a lot of real-world ways. If the We The People is the one you’re excited about, go for it. It’s a bit more high-end. Only thing would be to check any promotions on the Haro—I’ve seen a lot at 30% off. If it were a competition between an sale-priced Haro and an MSRP We The People, I’d go Haro.

Sounds good, just drop me a email & I’ll reply with pics.
Check out the contact page—it works now. You can use a Google Drive link or similar to send the pics. I emailed but maybe it went to spam.
As you suspected, it went to spam. I replied with pics & a parts list.
Thank you for your review. It’s very helpful. I stumbled across one of these online. It’s a second ride for me so just a fun camping type bike. I’m seriously considering it now based on your review. Also 6-1 so fit sounds like it might work
Thanks! And that is what I’ve started using it for—it’s such a great campground bike. Bombing to the beach, rolling trails, riding with the kids.

I’ve been looking for an “all around” bike for a couple months. I was close to getting an entry level mountain bike but didn’t like the riding position for a bike that I am basically using to following my 4 and 7 year old kids around. I was also looking at 29 inch BMX because it took me down memory lane. After hours spent looking for the right bike I found the Haro Klunkerson. It reminded me of my beach cruiser from when I lived in Crown point/Pacific beach area of San Diego but with a more aggressive design and features. I immediately fell in love with the Klunker. I looked at the State and We the People models. The State was too basic and WTP was a bit more than I wanted to spend. I just ordered the Klunkerson with a decent discount and cant wait to take it out.
Thanks for this write up! Just ordered one of these after flip flopping between a bunch of different klunkers. The pics of the modded one you have from one of these posters plus the fact that it was one a huge sale made me pull the trigger. Can’t wait to tear into it
Pingback: Klunker Alert: A Look at Retrospec’s Sully Klunker Bike - Klunkers
Have 4 State Klunker bikes. All are way tricked out. They all run White Industry cranks, Kris King head sets SE racing big honking&Super big honking handle bars With two rigged with Stermey Archer 2 speed hubs and one in a three speed coaster hub. Also the Stems are all high end U.S. made and all seat post are the Kalloy UNO good reasonable priced seat post and Brooks B67 saddles. Two bikes run Maxxis Hook Worm 2.50’s for bombing the streets, with the 3 speed running a set in it’s all black with red anodized parts looks,handling,and speed it earned the name the Black Widow. A full on blast plus wheelie machine it is. The other 2 bikes sport the big Surly 2.50 street dirt tires. All 4 bikes broke a 1,000 clams with the one kept as a single speed just braking that. So all are a blast but if you are on a budget ???? Huuum and want an out of the box bad ass chromo frame Klunker cruiser bike equipped with good parts that one would dream of building , then hunt down the We The People Avenger 27.5 cruiser Klunker. My local bike shop finally got one after waiting 2 years. I grabbed it. This bike is a rare find and it’s frame fits a tall rider better than the other Klunker bikes out there. It’s a quality bike and is a steal for the price. Too expensive to build, I think this model has been scrapped. So if this is the type of bike you like buy it there are a few left. There is a bike shop in Santa Cruise Ca.I don’t recall the name but posted in stock a week ago early Feb.2025. It’s simply one of the baddest ass out of the box single speed bike ever made for a thousand bucks ever.
Yeah, the WTP bike looks sick… but pricey and for me, I couldn’t find one. I think the Klunkerson is pretty close in terms of spec and quality though. Hasn’t broken on me yet!
You can’t go wrong the Klunkerson . Both that and the Avenger are both kind of under the same roof. However if you are six two plus, then the Avenger is really your ticket. It is really worth the hunt if you’re a tall person. They are only a couple of hundred bucks of each other. I know I gave up on the hunt for the Avenger for a while. Two long years. I thought the thrill was gone. When it comes to this type of bike for me, as I have only been riding them since 1969 the Avenger was like the one that got away. Kind of like walking around with a broken hart as I have been these old style balloon tire bikes almost all my life. But to keep this life long story short , every time I take the Avenger out for a short ride I kind of stretch the ride. The thrill for this model never left I guess. I too had my eye on the klunkerson but the seat post tube was a tad short and didn’t want the seat post up a mile. It looks to be a ton of fun though, and fun is hard to pass up. One thing to consider before you lay your hard earned cash on either. The Klunkerson is more the bmx type and the Avenger is more a mountain bike. Anyway it’s good to see you younger guys and girls out there still having a soft spot for the bomber type bike as we called them in Mill Valley Ca.,Marin County in the late 60’s. Last but not least if you want a more original fun coaster brake bomber and your on a budget with a frame built for war easy to find and really dose well with one size fits all? Than you got to have at least one of those State Klunker bikes. Plain simple easy affordable fun. A fantastic palate to modify to your taste. For me looking at the 4 heavily modified State klunkers in the garage got a bit out of control. Be careful. Fun can send you to rehab. So everyone get out and jump on a bomber and get in a little trouble , race your buddy’s ,charge the hill before the state of Ca.puts a tax on fun. Ride safe.
Thanks Gordon! Great comment. yes, I’m 6’2″ with a Klunkerson and the seatpost is up a tad high… but I still like it. Thanks for reading and posting such awesome insight.
Like the picture of Haro at the fishing pier. The Klunkerson looks like a real thrasher. I hope you collect more of these type of bikes , post and review them. I think these news boy beach bikes will never go away. They have style, cool vibe and are just begging to be a Hot Rod. If someone cannot afford a motorcycle or feels afraid of a motorcycle but wants the feel of riding one. Then the Klunker is the next best thing. After all what’s the real story of the Mountain bike or history of it in Marin County? I don’t think Charlie Kelly or Joe Breeze and Gary Fisher realize why they pushed the mountain bike idea or at least never mentioned it. It’s simple. In the fifties through the sixty’s Marin County had a lot of open space and fire roads to ride dirt bikes and a lot of motorcycle shops mini bikes were everywhere in Marin also ridden off-road but made noise. As the population grew in Marin so did housing which started stretching into all the near by trails in the70’s noise became a problem and dust. So after a while it became illegal to ride in these areas. So what what was the answer to that problem? You guest it. Turn your bike into a motorcycle that you can pedal thus born the Klunker = no noise. Put or adapt some motorcycle bars on balloon tire bike and go bomb those trails. Born out of necessity . That’s the real story however Charlie , Joe and Fisher are the organizers of the time trail events in the mid to late 70’s down Mount Tam backyard to Fairfax Ca. They really are the reason bike companies still make these Klunker Bomber bikes. They made this type of bike kind of popular. The Klunker is mountain bike history and hella fun. So I hope this is a good read to any new bomber bike fan. Also check out the Kosiki Brothers Bomber frame fork set. These were the first guys I ever saw put motorcycle bars on a bicycle I was only 12 years old at that time 1969. The last time I looked Don Kosiki is still making the Kosiki Bomber out of Mill Valley Ca. A very tuff Bad Ass frame fork set if one can score one. Happy Trails
I totally agree with you. These bikes are just plain fun. I’m working on the reviews and collections! If you ever want one of your bikes featured on this site, email me through the Contact form and I’ll happily post your bikes. Thanks Gordon.
Don’t have much more to add to the Klunker bike scene other than most of us use them as a dual purpose ride. Tires are a grate topic for you or anyone else to join in on for the long distance street dirt rides. My question about the Klunkerson is will your bike take a 27.5 x 250 tire? I notice your bike is stock with 27.5 x 2.4 which is close. If so you may want to try the Surly Extra Terrestrail tire. It also has a kevalar belt help stop flats. They really roll well on the street and rough pavement plus they work just as well and get good traction in the dirt . Not cheap. I think these tires also come in 29 ‘rs also. Do you or anyone have two cents to add to the subject? Not all Klunker bikes can handle the 250 width. My State klunkers all run 250’s. The Avenger will not. After reading the Klunkerson review I looked up the seat post dia. 31 mm. That is a good size. If needed l’d get longer seat post and sneak it up another 3/4 “. I don’t think it will look goofy. You’ll enjoy your bike a lot more. That’s my take. I almost bought the same bike last year too. The seat post change was already on my mind.
Mar. 7, 25. Just found in 2 in stock We the people Avenger 27.5 Klunker / crz At Santa Cruz Cycle Sport part # or mpn 1001210121 Perfect for the 6.2” plus rider. Kind of a rare find. The person I talked to said one is built and one is in the box and can be shipped. Hope this a help for any tall standing Klunker junky looking for a cool bike that as easy to find as Big Foot. That is Santa Cruz Ca. 831 area code. Good luck. 👍
