NOTE: The frame, fork, wheels, and a few other small parts were paid for out of pocket by Guitar Ted. Most of the cockpit components were gifted or sent in for previously written up reviews at no cost.
None of the companies represented in this review paid for this post or have any pre-knowledge of this review being done. As always, I strive to give you my honest thoughts and views throughout.
Now, on with the review.
Obviously the whole intention of the Honeman Flyer project was to prove if old 1930's track bike geometry had any bearing on current gravel bike geometry. It sounds like a far-fetched idea, but when you dig into history a bit, it starts to make more sense. I already wrote about this in an earlier post which you can read HERE.
In this post, I will give you my take on what this unique geometry feels like and how it handles on gravel roads in the 21st Century, nearly 100 years after bicycles with this geometry first appeared on the board tracks across the United States. This post will also dispel the uninformed notion that "gravel bikes are just 1990's MTB's".
A long grade I rode up during the Mid-South gravel event recently with the Honeman Flyer. |
The radical part of this bike is the rear end. The front? Pretty standard fare, actually, and I was quite surprised that 1930's track bikes would use numbers almost spot-on for a gravel bike made in 2024. However; no one is currently using the odd rear end geometry that the King Fabrications Honeman Flyer does.
Just to quickly recap, the seat tube angle is a slack, slightly less than 70° while the chain stay is currently set at 450mm with the slider drop-outs. That connects to a bottom bracket that has 76mm of drop, which is what the geometry I found dictated for the 1930's track bike geometry I copied. That's a little lower than most, but not as low as I've seen today by far in a gravel bike.
Just to keep things interesting, I went with a single speed specific frame and my gearing was "John Deere 4020" at 40T X 20T. A little lower than a lot of folks single speed gravel gearing, but my worst facet of gravel single speeding is climbing, so I erred to that side.
Remarkably, I found that, while standing and mashing was certainly possible on this geometry, seated climbing worked better. It just seemed to fit my style and was a bit less of an effort to do, which is counter-intuitive for single speed riding. Especially when your cadence drops very low.

I'm not sure what else to attribute this to other than that perhaps having the bottom bracket a little further in front than I would normally have. This made seated climbing more desirable. Standing and mashing was fine, and I have no trouble getting into a standing position for climbing, it is just that seated climbing felt better and less strenuous, despite the low speeds at times.
Even with the longer chain stays, I had no troubles with climbing in either position, dispelling any notions that longer chain stays are "bad" for climbing. I did get the rear tire to break loose twice during the same climb while standing but it wasn't detrimental and only was a brief "scratch" of the rear tire.
I've already mentioned that cornering was a trait I immediately felt was a big improvement with this geometry, and that single track section at Mid-South only furthered my feelings that this is a strong suit of the Honeman Flyer.
Another time when stability was prized was a brief moment during the Mid-South when I crossed over some looser dirt/gravel during a descent and the rear end broke loose. I was easily able to correct and ride it out, which seemed intuitive and not at all 'twitchy'. That was a nice revelation.
Another interesting thing about this geometry is that the wheelbase is not crazy-long. It measures a touch over 41 inches at 1043mm, which isn't out of the ordinary. My Twin Six Standard Rando measures exactly the same, as an example. The thing is, this King Fab bike rides like a much longer wheelbase bicycle. It is definitely springy in the vertical plane and because of that, it rides quite smoothly.
In fact, this is probably why I came out of the Mid-South without any physical issues. Normally my hands would get numb at some point, and the feeling of being "beaten up" would have been happening. However; I felt great after that ride, in terms of what I normally feel like, and I am pretty sure that was all in the bike's design.
Now with the slipping seatpost issue squared away I can ride the bike without a constantly varying saddle height! That has proven to be a good thing and has reinforced my feelings about the geometry. Oddly enough, I actually moved the saddle back a couple more millimeters when I swapped out the post and this has been a good move so far. I never would have dreamt that making the bottom bracket a bit further forward would have this dramatic of an effect on so much of the bike's handling.
Why, exactly, the old track bike designers made the bikes like this is still a guess. I can speculate, but without some definitive dissertation from a designer from that time, all I can do is guess. There was the reference I found that intimated that these machines were often used on rough, unpaved roads while training, so that would make sense if the geometry was defined by that part of the rider's needs for a racing bike.
Conclusions On The Geometry: So, are we the beneficiaries of old track bike geometry during these gravelly times? Maybe. I doubt that it was a direct influence, but in a roundabout way, we have ended up, at least partially, where we started.
As far as a connection to mountain bikes of the 1990's goes, it pays to keep in mind that early mountain bikes were an outgrowth of 1930's Schwinn/cruiser style bikes made for youths. (And their smaller diameter wheels, by the way.) Early MTB's were carbon copies of 1930's cruisers, in terms of their angles, as an example.
So, to say that "gravel bikes are just 1990's MTB's" is really missing the mark. Those 1990's bikes were evolutions of the first generation MTB's and their 1930's inspired cruiser bike geometry with smaller diameter wheels. 1990's MTB's were not the predecessor of the modern gravel bike then. Nor were gravel bikes influenced by those early MTB's.
The Parts: Some of the bits and pieces I used on the Honeman Flyer deserve a little attention here as well. I have Wolf Tooth Morse cages on the bike as well as their rear through-axle. I am using a painted to match Salsa Waxwing carbon fork, and those sweet TRP brake levers.
The bottle cages are actually really good. If I were to eject a bottle, it would have been on one of the bone-jarring high-speed descents at Mid-South, or in that single track they had there. But that did not happen and I would 100% trust these cages in almost any situation.
The through axle did its job, and that's a good thing. I did actually witness a guy have his rear through axle eject on a high-speed down hill at Mid-South. Frightening! Fortunately he was able to bring the bike to a stop without crashing. But that just points out that a good through axle used correctly is a key to a safe, enjoyable ride. Thanks Wolf Tooth!
The TRP brake levers on the bike which were gifted to me by a reader of this blog are top notch. I love the feel and the hoods are super-comfy for my paws. Thank you!!
Finally, the Waxwing fork was something I feared would be super-stiff and unforgiving. I was pleasantly surprised to find out it was nothing of the sort. That smoother ride and those Three-pack bosses are much appreciated.
Conclusions: So, with all of that said, does this bike do the things I need in a single speed gravel bike? To that the short answer is "Yes". However; there are always things I'd change about any bike I've ridden, and this one is no different in that regard.
First, I'd add another bottle cage mount under the down tube and I would have arranged for two on the inside of the main triangle on the down tube. But I am a water bottle hoarder and I don't always need that many mounts. Having just four places for a water bottle will force me to pare back on the packing! Plus it would have increased the price to me for the frame and I was on a pretty strict budget.
I'd probably ask for a tiny bit more tire clearance so I could run 45-47mm tires. No big deal. At least this bike has more clearance than the Twin Six does! Interestingly, it doesn't need bigger tires, mostly due to the already fantastic ride quality of the frame and fork. The Stormchaser single speed I tested in 2020 was a great single speed gravel bike but the front end of that bike was super-stiff and unforgiving. It took me putting in 50mm tires to tame that. It is nice to have this Honeman Flyer be so smooth, and lighter, since it doesn't require those heavier, fatter tires to smooth things out.
Otherwise I am quite happy for now. I don't see anything glaringly "wrong" with the geometry. It is a super-smooth riding bike. The wheels, especially the Paul Components hubs, roll like crazy. The handlebar is comfy and along with the smoother ride, my hands are pretty happy. So, yeah.....this one is a keeper. I am excited to roll with it for years to come.
