I don't know the proper name??

Guys,
I am attempting to mount a long gun carrying rack (gun case) to the front forks of both my E bikes,
the Wart Hog bike poses no problems,
BUT,
the Juggs 4 bike won't work because the way the front fork operates/compresses.

In simple terms,
the WH forks compress at the bottom, with the bottom ends going up inside the fork arms,
all the compression action is at the bottom of the fork arms,
BUT
the Juggs bike is just the opposite, the forks compress into the fork legs from the top,
then goes into the fork arms, all the compression action is at the top of the forks.

I have clamps that can be attached to the top/middle of the forks, that will hold the rifle securely.
I do not want to mount the rifle to the handle bar or carry on my back, been that route and don't like it.

What is the correct name/terminology of the 2 different types/style of Forks?
Thoughts or suggestions...
Tia

Conventional and inverted.

On inverted forks, the stanchion (tube) is on the bottom. Not sure if this is correct "bicycle" terminology.

Inverted forks
I personally think it's a better design because any dirt stuck on the stanchion will be pushed down and fall off.
Crap on top of the stanchion with a normal fork, can work it's way into and wreck the seals and sealing surface.

Also, the outer tube of the fork has a larger diameter than the inner stanchion tube, so the outer tube would be more rigid, and better to be attached to the frame than the wheel.
A smaller diameter inner stanchion should weigh less too, so less moving mass.

I actually bought double shoulder downhill inverted air forks with a thru axle for my new ebike before the ebike arrived thinking they would fit, but the steering stem was too short.

I needed at least a 260mm steerer tube.
I also bought new 29" front wheel, Shwalbe Hurricane tire, and tube to go with it, but it's All been sitting for more than a year, brand new and unused,..

I ended up with SR Suntour downhill forks with 160mm of travel but they aren't double shoulder and they aren't inverted.

I do like the Suntour forks, but I still like the idea of inverted and double shoulder.

I can look down the stanchions as I'm riding and see the stanchions wobbling front to back on my Suntour forks.


They do have a pretty cool quick release front axle, but I haven't removed my wheel very often.
I don’t need to remove my front wheel in 4 seconds flat.

Thanks Guys
Spent several hours looking for a inverted 100mm suspension and Quick release bottom, for use with a 4" tire, kind'a like hen's teeth, that can't be found, so far.
I got solid axle comin out my ears.
Still hunti'n for less 3 bills or less, found several that were 8 bills plus "OUCH",
for the go faster down hill low flyers...lol,

Hey PC, I hope that ain't yours, going to be real hard getting any ridin done,
with the air line thru the spokes...lol

Hey, NV...

I’m not sure if there are too many inverted forks for fatties. I wonder if there’s a monotube fat-tire fork and/or how expensive it would be. I don’t recall seeing anything.

Good luck.

Thanks Chazmo,
Found lots of them, but only for 150mm solid axle, the 135mm QR for the Juggs 4 seems to be hiding somewhere, but I got "Chance" and "Sage" hunti'n them...lol

From my limited experience dealing with E bikes, I'll probably have to change out the front tire to a 135mm solid axle. If that's the case, then Juggs 4 will stay home and her OLDER brother the Wart Hog will see all the action, and that will really bend her out'a shape...lol

I am not sure what you mean by monotube front fork?

I have found a 135mm QR front fork,
but it had the double sided tubes going past the steering stem and I think that won't fit the Juggs 4 bike, and allow for steering/turning etc.

Sorry. “monoshock fork” see,

Oops! We ran into some problems.

Both my ebikes had the same RST Guide coil spring forks with 135mm axle spacing and QR skewers
And like you said, there isn't much available.
The only air forks I could find with lots of travel had 110mm spacing, so I had to get new wheels, tires and tubes to go with the forks and their fatter 15mm axle diameter.

but it had the double sided tubes going past the steering stem and I think that won't fit the Juggs 4 bike, and allow for steering/turning etc.

They call that "double shoulder" and there is a good chance that they will allow for all the steering and turning that you'll need.

The only time you you ever really turn the handlebars more than a few degrees of rotation is when you're pretty much stopped.
Once you're rolling along, there's not much movement in the handlebars.


Make sure to find out if you've got a tapered or straight steerer tube and how long the the tube is.
And keep in mind the the "upper shoulder brace" takes up some space on your steerer tube with double sided tubes.

The double shoulder forks have rubber bumpers that keep the fork tubes from hitting the frame.
And the fork tubes are in front of the steerer tube by an inch or so, and that gives you more room for steering as well.

I spent Hours trying to find an air fork with 135mm spacing And a tapered steerer tube and finally gave up and bought a whole new front end.

I didn't notice that.
I sure looks like my brake line is going through the wheel.

Here's a closeup of that picture,..

It still looks like that one spoke is behind the brake line.

They do have suspension steering stems which would save you a lot of money.

But the whole front end of your ebike would still be bouncing around.
(That whole suspended weight thing)

If all your looking for is a more comfortable ride, then a suspension stem might be good enough.

It won't do what a suspension fork does though.
(Air forks are fricken nice. I'm riding on a cloud made of marshmallows. )

Look at the line running BEHIND the tire/rim!!!
Top of the photo... and a couple of spokes also...

The reason I wanted to find a new fork, was because I can clamp a couple of soft gun rack clamps to the fork leg for carrying my air rifles, small game season is almost here in Oct, etc.
I can't clamp with a standard NON inverted fork...

Yeah, I know.
It's an optical illusion or something.
My brake line is not running through the spokes.
(I do have solder wrapped around the top spoke. I used it to balance my wheel.)
The brake line, caliper, and brake rotor are all behind the tire.
All the spokes are in front of the brake line.

I don't quite understand?
I would think that you could just use a bigger/smaller clamp or spacer to make it fit either fork?

If you're worried about the outer fork tube hitting the clamp, most forks don't travel the full length of the stanchion before they bottom out.
There's usually a good inch or so of space at the top of the stanchion that never gets used by the travel of the fork.

You could take some measurements and turn your preload all the way down, then compress the fork to see how far they compress.
You can measure the listed travel of the fork and add that distance above the fork seals, to see how far the fork compresses.


And BTW,.. you can buy a new QR skewer for about ten bucks.
It would suck to leave an ebike at home because of a missing skewer.

I can't use a standard fork, the clamps need to go where the standard fork has it's compression stroke/area's.
On an inverted fork, I can clamp any where from the top down to 12>16" down the fork, there is NO movement of the fork legs in the top section.

I am still pencil whipping this mounting problem.

On the Wart Hog, I can mount the AG on the back basket that is 20"+ long,
or just underneath the basket or on the front inverted forks, just trying the most stealthy area, as a result of these stupid days/thoughts etc.

I'll try finding a 12/13"w x 20/22"l x 4/6"h HD basket for the back rack, that's the easiest method found so far, just not as stealthy with 6" of the butt stock hanging out
the back of the bike..
