Cyclekarts: Simple, Fun Vehicles

No, this isn’t some miniature sports car from the 1920s. This lightweight racer was built just a couple of years ago. Welcome to the world of cyclekarts.

The cyclekart phenomenon is a reincarnation of the cyclecar enthusiasm from the 1920s, when a generation of racers were completely focused on lightweight, raw performance. Reader Steve Vinson and his 9-year-old son are hooked on it, and have some tips for others looking to get involved as well.

Why?

Ever felt the desire to go back to basics and experience driving in its most visceral form? These karts are an attempt to accomplish just that, providing a jump back into the extreme basics of driving.

What Is It?

Cyclekarts are extremely lightweight and usually sport a 6.5-horsepower Honda GX200 engine or something similar. A Comet Torque-A-Verter transfers power to the wheels, making this a clutch-free affair. Make no mistake, however: They can move. Steve says that max speed depends on gearing, but they can hit about 47 mph.

What Can It Do?

These aren’t just novelties built to attract oddball attention; there are clubs that regularly meet. Steve’s group, the Arizona chapter of the CycleKart Club, started out with just three karts in 2015 and now counts a dozen finished karts among its members.

“There is a very active group in the Pacific Northwest,” Steve adds. “They call themselves the Gittrevelle Grand Prix, and they hold an annual event called the Tieton Grand Prix each June in Tieton, Washington. They are expecting 30 karts at this year’s event.”

How to Get Started?

Getting involved means building a kart. “There really aren’t plans for the karts,” Steve explains. “Most builders follow what other builders have done and modify the frame size and body design to suit their own personal taste, and in most cases, the limits of their abilities. Pretty much all the karts that are built are designed from scratch and shaped to look similar to the chosen inspiration car.”

How Much?

Steve says it took about six months and $2500 for him and his son to build each of their karts.

I've wanted to build one but I hate the one wheel drive/ one wheel brake chassis setup. You guys should price out the cost of all the parts to build one of these though. Buying new, just the engine and transmission cost about $1000. Also the "proper" 17" cyclekart wheels are becoming difficult to find cheaply. You will basically be buying all your wheels from a different seller so they will all be in various states of disrepair. There are some 14" pit bike wheels on ebay that would work well but not have quite the same look.

New "Honda" 6.5 hp engine on sale right now for $99.

Seems this can be built really cheap.

From what I can tell the wheels are gonna be the hang up for the price. You are looking at the small competition motorcross bikes for any consistancy as the Honda CR80 (small wheel) had a 17" on the front. 16" and 19" are much more popular.

Edit: Just found the Suzuki RM85 has a 17" front.

Edit again: If you go to a 16" rim instead of the traditional 17", price drops wayyyy down as a 20" bicycle rim will work. (bicycle wheels size is actually the external tire dimension vs the rim dimension as quoted on motorcycles and cars)

Hey I don't mean to be doctor negative at all. Please go for it. It also looks like the ultimate father/son/daughter thing. Build 2 so that you'll always have someone to race!

RE the 1-wheel drive thing, they make mini differentials, better brakes, bigger motors (duh) et cetera, but it's so easy to get into scope creep that you end up with something much more expensive, complicated and nobody with an equivalent vehicle to race. It seems that the winning formula is to save your self-expression for the body and stay with the specification for the working parts.

These things are cool to look at and probably fun to make - As something to make with your kids it would be great. But... what the hell do you do with it when you are done building it? My lawn tractor seems about as much fun to drive except that it is actually useful for something. Maybe build a ramp and jump it thru a flaming hoop or something... that would be sweet.

They don't seem all that "back to basics" to me either. Spoke wheels? Fluid drives? A regular old rotax kart is lighter, simpler, faster and handles better so if it's really about racing - you get a racing kart. And go racing.

This is just about fashion. I don't have enough man bun and skinny jeans to rock one of these.

Racing karts are are primarily for competition, cycle karts are primarily for fun. It just depends on what you're really looking to get out of your driving event experience.

The main thing possibly, but not necessarily, holding me back from eventually getting into cycle karts is the small number of available events to participate in each year...Even if I'm not that far from the biggest event in the country.

I do think a "Morgan 3-wheeler" powered by an appropriate output GY6 would be a great way to do it though.

Rather than using $500 worth of motorcycle wheels and tires, we use 12" trailer wheels and tires, $160 from Walmart or Jet.com

Spindles and hubs are another $119 from Etrailer.

I have a 500cc V-twin on the floor in my garage. I'm 100% certain someone on here has a liter bike engine laying around as well. I think that's a Pandora's box we don't necessarily want to open.

I'd probably have a spec for the engine at least, even if all it says is, single cylinder industrial engine and keep the motorcycle and race kart engines out of it. The idea being to keep the speeds down so we don't end up with a bunch of fully caged A-Mods and send GRM insurance into apoplexy.

I'm indifferent to the drive and other specs. I'll probably build something that can play with the Cyclekart guys, so I will probably follow their suggestions fairly closely.

My sons have also shown some interest, so we might be building 3 of them. I happen to have three 6.5hp engines and two CVT clutches that I can rob from other toys to use.

Single cylinder industrial engine: definitely agree. Hadn't thought about literbikes and such.

How about a budget cap? Say $500. That should be enough for anyone, but low enough to require getting resourceful. Kinda like a 1/4 scale challenge/challenge car.

Id love to see someone come up with awd....

Would venue be dirt or asphalt? Or both? Id think dirt would limit rollover and safety risk due to lack of available grip.

And requiring a vintage style would allow for freedom but restriction. Sure, someone could clone can am cars. Or vintage indy. Or a 34 ford dirt track. Ir.....

I could be interested in this for next year.. assuming the recipe does go below well below the $2500 number that gets thrown around a lot.

I like the quarter scale, quarter budget idea. The only rules I would make hard (other than safety) is the engine specs. That prevents some one from showing up with a super bike engine and just blowing everything away.

As far as AWD, that would be interesting with one wheel power and one wheel brake.

I'd say replicate the break and drive system of what you are cloning. If you want to clone an all-wheel-drive monster go ahead. If you want to clone a vintage Indy car that had a peg leg go ahead. If you want to do an old dirt track special that had three wheel brakes go ahead. I'd say a minimum of one wheel drive one wheel break.

Seems to me that if you don't have a pretty serious spec, what's to keep someone from simply showing up with a hopped up clone Kart with "vintage inspired" bodywork? One has to consider what key parameters will create some semblance of a level playing field. As I see it will be the motor, the cg, brakes and how much rubber you can put on the ground. Control those and you'll still have a lot of room for creativity, but the performance spread won't be a joke. Also - this should be the one challenge event that actually has w2w racing.

Been lurking on this thread. I showed some pictures of these karts to Mrs. VCH and she loves 'em. The biggest little VCH is 3 years old and starting to get interested in cars. I think she'd love one of these to tool around the yard in.

The biggest hurdle I can't seem to get over mentally in building one of these is how to make the wheels, drive, and engine all...work. I have some vague theoretical knowledge of a chain drive, pulleys, and axle, etc but I have to confess, I have no idea how to make it work in practice. I mean, stupid stuff like, how does one mount the bearing? What bearing to use? What makes an "axle"? In my head, the easiest thing would be to have a solid shaft as an axle that both wheels fit onto and then drive either one or both wheels- make some sort of a "fixing" mechanism so either the left, right, or both wheels could be driven or freely rotate (so the kart could be pushed without being connected to the drive).

How does the sprocket locate on the axle, without moving side-to-side?

I'm just so used to a solid rear axle, like on a car...

I guess I need to see some pictures.

The steering and front end I can sort of figure out...trailer spindles are pretty easy to find.

In reply to FlightService:

My understanding is that, at least currently, there are no "rules" to "dictate" anything. Just a few loose guidelines, which are by no means the same as rules, as well as what is little more than a "gentleman's agreement" on the basic performance parameters. It's pretty much build whatever you want as long as it fits the look, feel, and spirit of the event.

I would think if GRM'ers need a more defined set of rules, with the intent of making it more of a true racing competition, then the rules should be written to ensure traditional cycle karts would remain competitive. So things like weight penalties for more powerful engines and whatnot. Make it not at all advantageous to go bigger and better, thus keeping it 'dual purpose' build friendly and preventing too much performance creep..

Maybe we can get a SC club started to race them.

Something like this to start.

I will make that commitment as well.

Maybe not quite to cyclecart rules, due to material on hand already. But definitely to their intent. Ill bring it to the challenge as well next year.

And toyman, wanna race sometime next year?

I'm gonna think joining this, I make no promises though. Seriously thinking about using the rear axle and some suspension parts off of this dead Kawasaki Bayou I have laying around. This would be my first ever semi major fab project so I'll have to do a lot of figuring on how or even if I would want to approach it. It may prove simpler to lean closer to the traditional recipe. I want both rear wheels driven though if only because it will be more fun when used at home, mostly on dirt.

EDIT:

Wondering if a mini Model T Speedster clone is close enough to what we're going for here. Biggest think I'd have to figure out then would be the wheels.

Before we all get too crazy with the ideas.

We all agree on the spirit and the concept of the thing. (single cylinder ect)

Can we at least agree on a budget?

At least ball park?

I really like the quarter scale, quarter budget idea.

I vote for half budget. It is going to be next to impossible to leverage selling parts like a traditional challenge build.

Having to buy parts outright can make $500 disappear pretty quickly.

Are we actually racing or just all deciding to build something and haul it halfway across the country to take pictures of them together? I'm cool either way, mine is going to be more show that go even If I'm thinking about making it needlessly complex.

Racing. Even if we have to commandeer a parking lot somewhere and explain ourselves to the police.

We can always blame it on GRM.

Anyone have any suggestions for what would look good coming off an el Camino?

Should we start a new thread?

Ok, so which one of us is showing up with a 2 stroke dirt bike engine using the excuse that a donor bike was cheaper than a tiller engine and is still technically a small single cylinder?

Also, do I get more cool points if I haul it down there on a tiny trailer behind the GTA?

Ok but what about a twin cylinder engine purely because I think it would look cool? (Seriously I've got an old Kohler twin cylinder generator engine here that I think would be pretty sweet sticking out of the sides of a tiny cowl)

I'm going to shoot for less than $1000. I'll keep an approximate budget.

Spirit and concept works for me. Like was stated earlier, much like a truck, you will know one when you see it.

Yeah, the more I think about it, the ATV donor idea is way outside of the spirit. I will probably still rob smaller parts of it though.

I would by all means steal the steering, hubs, bearings, uprights, chain, sprockets, and any other small parts I thought I needed. There is no reason to make or buy something when you already have what is needed on hand.

I say we blame on screwing up Majorie's deck and we are running for our lives.

I could care less how it looks, you could play with the exhaust on that thing to sound wicked

Id be ok with a kohler twin.

Good luck finding a clutch or cvt rated for the torque though.

But do it!!!!

Ill go one better here: if we all get these things done by spring, i will find us a place to meet, race, and feed lunch. On me. Maybe even do it as a large scale meet and greet for the tri state area. (Nc,sc,tn) virginia would be allowed, but only if they bring fresh clams from the Chesapeake bay.

I think that a DIY Frazer-Nash 'chain-gang' style transmission would be perfect for the spirit of the event.

Admittedly, this the independent engine and CVT is one of the reasons I'd lean towards building a Morgan 3-wheeler using a GY6 (clone) all-in-one engine/CVT/swing-arm from a scooter and tuned to about the same 10-11 hp as the unencumbered GX200's in the cycle karts are claimed to make.

Depending on where you live there are growing groups all around the world. Here in Arizona we have two events scheduled over the next two months. Sept 2 and 3rd in Boulder City, NV and October 21 and 22nd in Victorville, CA. Both these events are at organized race tracks. The Nevada event will be at a paved 1/5 mile oval track, the SoCal event will be at a paved .7 mile race coarse. We are adding new events and finding new tracks all the time that are happy to have us come out and play.

are there particular rules that must be obeyed (and a link to said rules) or is it a spirit of the event type thing?
