Sondors X and Air Forks

Recommended Posts

I just ordered a new X model and want to have air  front suspension ready to install on the bike when it arrives in June. I saw the air forks available on the Sondors site, and have looked around at Luna and Bolton and third part shocks that may or may not fit or may or may not be available.  I have two questions:

1. On the Sonders site it appears to be two shocks available for the X model. One that will only fit pre Jan 2019 bikes and one that fits only post  Jan 2019 bikes. Anybody know what changed to make these incompatible? Maybe a tire size, or is the frame somehow different?

2. Are there any published specs on the measurements on the current X model fork?

 

Thanks for your help.

The first release of a Suspension Fork, for the Fat and Narrow models of Sondors, is a very inexpensive spring fork with non adjustable dampening. Lots of owners expected something better. I’ve got one on my narrow and would rather have a solid fork. But for my type of hard pack and pavement riding, it’s just extra weight.  I don’t ever "INTENTIONALY“ plan to catch air .))

The second and newer models of Sondors were offered with an Air Fork, that allows some adjustability. It’s considered much better. But if you have a SERIOUS need for suspension (most users just like adding more equipment to personalize their rides) you should consider purchasing a quality suspension fork instead of being disappointed and continually upgrading. 
 

Nope that was wrong and there are  TWO Air Forks available not as I thought. My Bad. I’d surmise that it’s either the steering tube diameter or length. There might be a steering geometry change in the newer model Sondors X. But that’s a pretty moot issues since you’ll be getting the latest model.  I know that the Fat Frames have changed to accommodate the larger battery displacement after the 48V option and gotten longer with more room in the battery box. 
Be nice if we could get real world data and measurements on each model, including the Fork but even Electric Bike Review is sketchy and Sondors.com is not much help.

Thanks Reddy, I appreciate all of the information.  Yeah, the issue is that there a lot of reasonably priced third party fat forks that look exactly like what I see in pictures of Sonders X with air suspension, but with those 4,9 inch tires, will the third party stuff really fit the wheels? I can't imagine that Sondors has someone making a proprietary sized fork that only fits their bike, but I could be wrong. Guess I'll wait until I get mine, and just take it apart and measure everything.

Most modern Suspension Forks, for Fat Bikes, are for Thru Axels or Quick Release, as is the case, I believe,  with the Deal from Bolton. I would hate to give up the extra security of axel nuts on our Sondors. But if it’s a matter of getting just the right fork, a new hub, built into your rim ain’t out of the question. I’ve built NEW, BETTER , STRONGER, DOUBLE WALL WHEELS with heavier 12 gauge Sapim spokes because that was what my upgrades deemed necessary.

But it’s always a required prerequisite, when shopping, to communicate with the vendors for advise and clarification, even if you think you know what you’re ordering and getting. I do believe Luna (electricbike.com)  is one of the best resources on Fat eBike Suspension Forks but I’m guessing you’ve already figured that out. 
I must say that I’ve been thinking of buying another suspension fork for my Sondors Narrow with triple clamps and the question that looms most,  is how that will change front end geometry. Rake and Trail should stay about the same but my front wheel would be more forward that it was. That should add some straight line stability but will that cause any misadventure in cornering? Dunno, but probably not.  There are two reasons I’m considering the upgrade, Dual Front Brake Rotors and the Ease of Mounting the Headlight I have for it, it’s huge and was the  original headlight from my Suzuki GS1100EZ when I installed the smaller headlight for that Cafe Faring.

On my 1st Gen Fat, that’s no longer a Sondors except for the Frame Fork and Battery Box, I built a wider 100mm double wall rear wheel and use a 26 X 4.7" Vee Tire Mission Command II rear tire (now discontinued [CRAP I love these tires]) and my next change will be to the Vee Tire Apache Fatty Slick (already in reserve) but for the Front, I built a 80mm (narrower than the original Sondors Fat wheel and I run Vee Tire Mission Command II 26 X 4.0. and I have one in reserve and might buy another before the suppliers are sold out.

My bike handles fantastic compared to having  that Monster, Heavy, Donut on the front.  Handles like a Moto GP bike on pavement. 
I’ll probably keep my original light, narrow, wheels on my Sondors Narrow as it already handles great but I’ll  have to build in a new dual disc hub into that Original Narrow front Rim.

Don’t settle for almost good. You’ll appreciate getting just the perfect fork for your ride.

Great stuff! Looks like you've been busy!

 

I've communicated with Luna, and it sounds like they will not have any inventory for a while, and from the Bolton site concerning their fat tire fork:

     " Tires above 4.5" are not recommended as the fit can be very tight." The  current Sondors X are 4.9

Yeah, that’s what mine were. Although noisy and that translates into rolling resistance, they are some of the toughest, most reliable tires around. They did have a bad batch that surfaced on Sondors bikes over a year ago where tires were showing signs of splitting, where there was a weak seam in the carcass but we didn’t hear of a lot of cases but it was a topic on the Forum for a few days as owners chimed in. 
‘You’re wise to take your time in selecting a fork, of course sounds like the market is constipated ..... right now and with the easing of the virus in China, the supply chain should start to ease up )).
You’ll be so thrilled when you get your Sondors X, you won’t even mind the bugs in your teeth. 
‘Tell me this?    Are you dreaming about riding it?   
You could PM https://sondorsforum.com/profile/901-lindsey-nguyen/ and see if she has any suggestions on a good suspension fork, she’s one of our most trusted vendors.

Thanks. Yes, I'm curious about the whole Ebike scene. I'm and old dirt bike guy who did trail riding and motocross way back in the 70's. I did a lot of street and off road bicycle riding in the 80's and 90's. I'm retired now and the ebike looked like something that could get me back on two wheels and on backroads and trails. I looked at e-motorcycles and concluded that I would probably hurt myself trying to do some of the old MX stuff that I did as a kid, so I decided to try and ebike to see if I could get some exercise and enjoy the dirt roads and trails that I live near. I think I choose the Sondors because it reminds me of a fun trail bike that my friend had nearly 50 years ago. How's this for a fat tire bike?

You’re Speaking My Language and we have  parallel years long interests. I remember those back woods mechanical mountain goat, two wheelers and if I recall there as even one that was a two wheel drive. 
I had a variety of dirt bikes. Starting with a Honda 350 that I removed all the street legal electrics, but it lacked any real off road capabilities except Scramble’n. But I had a Montessa 250 Enduro Desert Racer, 250 Rickman Montessa Trials that I still have the rolling chassis, and a Sachs Peyton 125 that I bought for my wife and we’d trailer them to Colorango to ride with a friend that had Husky. I also still have a Susuki X6 Hustler and my 82 Suzuki  GS1100EZ.  But I gave up riding smokers years ago because I decided I wanna LIVE. Hasn’t stopped me from shopping Cycle Trader though.

Damn, those are some nice bikes. That was a great time to be alive. I started out on a Hodaka. I also had a Puch 125 MX and a Husky 250.  The modern MX bikes look like toys to me. They don't have the character of the classic bikes. Yeah I'm definitely too old now for anything but looking at them. So does riding an ebike on the backroads remind you of the good old days? I'm hoping it does that for me.

Hey! These ... Are The Great New Days ForCycling.

I’ve Still Got All The Conventional Road Bikes I’ve Ridden Since The Mid 80’s. Except one, maybe the best one. I have 13 bikes, in all, starting with a Schwinn World Sport (couldn’t afford a Paramount back then).  I rode a no name French Framed 10 speed in the 60’s and I know it was French because of the Bottom Bracket Lock Ring Threading was French. I was one proud cyclist when I installed a Simplex Friction Derailleur. I rode a 1986/87 Cannondale SR800 criterium for 13 years as my primary mount. I bought it in 86 but crashed on it, while reaching for my water bottle and hit an asphalt heave, fell and broke the derailleur hanger that was part of the rear drop-out (a year before the started installing replaceable hangers).  Cannondale replaced that frame with a 87. Still have it and kept it all original with replacement parts that matched originals, except for the wheels.

Then I bought this preTime Trial bike in the late 80’s and it was called a Funny Bike because Funny Drag Cars we’re popular back then it’s an 1985. This thing is torture to ride now that I’m older. image.thumb.jpeg.31028bc192b59f764c185c0c443d1290.jpeg

I’ve got two of these Cannondale H400 hybrids, this one is my touring and other is my City Bike that I carry in my Grumman Aircraft to explore when I travel. 
 image.thumb.jpeg.f1f526b9c6452213fc334d39b06f7ea5.jpeg

But I built this LiteSpeed Ultimate in 1999 and thought it’d be my last bike, I’d build  &  ride... nope then I got the Fat Bike Itch, then Electric Bug.

I had a matching 1999 LiteSpeed Vortex but in a financial panic, I sold it.  I always intended to replace it and add a 2003 LiteSpeed Blade to have a trio of them. You know that Lance Armstrong’s first TDF championship win, although he rode Treks, as his Sponsor, his time trial bike was a LiteSpeed Blade painted to look like a Trek. Have a couple of older 10 speeds of no consequence and a Specialized Rock Hopper.  I couldn’t part with most of my rides and selling that Vortex was a terrible mistake. 
You’ll get back in the groove with your Sondors ...makes us retired guys faster than the current crop of roadies. ))
