  • So you are using two different viscosity of oils ?

    I can see you are using SAE 4W - thinking about doing same with viscosity of SAE 2,5W. Your mod giving me hope that suspension is more tunable !
    I still having rebound on max slow - I hope it will even slow rebound down more. 

Have you tried increasing rebound instead? Too low rebound can make the wheel feel dead and paradoxically the ride will feel bouncier since rebound is not fast enough to prepare the suspension for the next bump.

Thank you for input - didnt know that !

Do you think that viscosity of oil "in compression leg/side" will affect compression/softness  - or if I just want it softer is better to use less of thicker oil ? Should I get two different oils as well?

I kind of assumed there is simple butterfly valve, but it is probable that its more complicated.

I did both (lower amount only or nearly only affects the compression, and there is no effect on the rebound) 

One thing i dont know is:

if the viscosity on both legs differs massively from each other (for example 2,5WT on comp and 15WT on rebound) , how is the outcome/interaction¿ because in the end both legs get bridged together and acting as one unit of course , so it affects each other a little regardeless...could be some try and error in your case also...

first i would try to test with faster rebound like rawnei mentioned but if you truly want to decrease the rebound speed then i would love to hear your conclusions and which oils you used 

 

I posted this already earlier in the thread but below you can see the effekt of viscosity/amount/both combined for compression (graph shows more oil and higher viscosity,  but vice versa if you want it to get softer)

ps.  nice 3d work.    

I don't have a 3d printer so apart from getting the jump pad extensions printed off I've done all my mods old school way ;-)    polymorph,  glues,  plastics.   The mud/dirt guards might be inspiration for some future design.

I like your seat. It would need to be farther forward for me though.

I have the seat that came shipped from ewheels, but I don't like the feel at all.

I have to sit practically on the screen to accelerate, or maintain speed.

It's not very thick, or plush in the front like that, and hurts my legs and ass after a while.

I think I'm going to try to add foam in the front to raise it up, and make it softer.

I love all these DIY ideas. Thanks!

This adds just enough height and adjustable comfort for me. I have one on V12HT too. Comes down sides just enough. It will cover your screen though.... https://amzn.to/3TnCgrD429139759_1393443767944341_2507357299142020638_n.thumb.jpg.0d334786290f064712eb05acd9382622.jpg

Salut

Est-ce que quelqu'un sait ce que le lot 3 apportera par rapport au lot 2 actuel ?

J'imagine que ce ne sera pas seulement une quest

Unlike other brands, you won't see much difference between batches at Leaperkim. All batch 1 wheels are unaffected by the issues which are minor and easily corrected by the firm.

Its only because I had a pitbike seat on the shelf (cut down for length and re-stapled the cover on),   otherwise I probably wouldn't have made it so tall,  but it works extremely well.    I had the bidou (?) one from the patton (still do,  anyone want to buy it?   AU) but it was way too low and hard for my delicate touche.
Can't get it much further forward without affecting seeing the screen,   it is biased rearward a bit more than would be perfect but its usable and comfy so,  meh,  done enough for now :-)

I took off the trolley handle because with the seat I just don't need it,  and scored enough space to make a little "glove box" under my seat.    I used U saddle clamps at the back and velcro at the front so I can lift the seat up to get under it. 

Have a squiz too at the little flat black plastic addons at the front and rear to stop dirt getting thrown on the front and rear plastics.    Made a little mudflap extension too,  but the side shields are working very well themselves and a simple diy mod (bit of glue or double sided tape and some flat plastic sheet  (from a plastic clear pocket folder for the material : op shop - $1)

What voltage drop you see guys on yours 50s wheels?

I have at 50 km/h  aprox 2 kw+  around 10-12v voltage drop in cold weather 3 degree C, with 50e lynx.

There should be almost no voltage drop on 50s  - thinking about selling batch 2 50e and getting 50s batch 3.

Can somebody pm me some log/ride from EUCworld, I would love to compare it, if it is worth it.

I'm having a weird issue with my Lynx and I'm wondering if anyone else is having the same issue.

I was out for a ride and decided to turn on my headlight, when I turned it on the wheel slowly dipped forward. After some testing I found when the headlight is turned on there's a loud whining noise and the wheel slowly dips forward and corrects itself after about 10 seconds, once the headlight is turned off the whine goes away. I checked again this morning and now it's dipping a lot more forward. I'm in contact with Ewheels and they're in contact with LK.

I'm having this exact same issue. I should have gotten a video of it but I could reliably get it to dip when turning the headlight on. as soon as it was off it would slowly level back out. 

Once I got home it stopped doing it - this is quite concerning.

Did you update the firmware to latest version?

here's some photos that might be helpful in making a decision on buying.

first off, the tire is a joke. i worry a 200 pound man will wobble off this wheel and sue jason out of business and i won't be able to get parts. kinda hard to ignore gravity.

38CBD3E7-DB5A-4663-9128-EAE8BF1D9674.thumb.jpeg.59925c549c19532b8adbd696d9f67102.jpeg

 

pretty jason put this in his email welcoming letter.

Tire Pressure:
 
It is important to maintain adequate tire pressure; at a minimum, the tire should be inflated to >35psi, adding more pressure to account for higher ride weight. If the pressure is insufficient, this can result in the rim being damaged by contact with the ground—this is an expensive & time consuming operation to replace.
 
esp when max pressure is 33psi. at least jason is learning about tires finally. but i would not sell another one without pointing out that the max rider weight at max pressure, 33psi, is 177 pounds. 
 
and for all the leaperkim lynx fans that act like they work for leaperkim, i'll probably buy another one because it has a tiny bit more low end torque than the s22's, i haven't tried jason's 40t model, it might tie the lynx. i know one thing, i should have immediately taken off those stupid toe things, they caused me to dump the wheel on a slow u-turn. 
 
btw, i don't know what angle they are talking about when u set the shut off. is it 30% from perpendicular to earth, or 30degrees from horizontal, either way it played dead nicely when the toe things screwed me up. gone now. i need some rubber plugs to fill the holes.
 
pedal dihedral is fine, not too much, just right. if jason hasn't shipped my bedou pedal drop thing, i'll tell him to forget it. pedal height is fine for me.
pedals suit me fine. they are sharp or pointy on the edges moreso than other brands?

yeah, take these toe things off before they jam u up like they did me.

might go ride a bit more. got in 15 pasture miles and i'm impressed with the range because pasture/raw earth riding eats electrons. 
and no way would a v14 or patton work here. i saw holes, rode over holes that woulda swallowed those little 12 inchers.

suspension wise, the big question, and i haven't done anything to it yet, 
about the same as a good working s22 suspension or v13 suspension, as i had figured. no big deal. right now it's falling between my 750 pound s22 and the 900 pound s22. it's like a 825 pound coil spring on a s22. it's nothing special, so far. i'll screw with the settings later. but 66 pound was the best choice but if i could get a deal, i'd take a 70 for the next one. 62 woulda been a mistake. 
 
all in all, i like the wheel, feels exactly like a s22pro with a tad bit more grunt down low.
 
hopefully hou's v13 pedal backplates will make the power on the v13 available.

just did a couple more pasture miles before dark. yeah, me dropping the wheel on the u-turn was all because of the stupid toe hooks, and leaperkim is like every chinese euc company that doesn't know human or alien skeletal structure. i'm gonna ship king song, inmotion and leaperkim a skeleton of a leg.

i either must have a big ass or y'all have big beer bellys, because moving my feet to this position made it waaay better. still not like going from a ford pinto to a vette, more like a cadillac  to a mustang. definitely peppier off the line with my feet position properly. hou is already working on it. definitely for me, i don't need to drop the pedals, just move forward to make it correct. 

like i said, haven't touched the suspension, so idk yet.

i do like the big handles for moving it around in the hangar. 

gotta get beauty plugs for the front toe thing holes. and i guess i'll get hou to make 2 forward pedal shits.

i hope that bumper/toe holder isn't structural.

The only thing that helped with this issue was changing out the DC board, its not as bad now but it still dips slightl. Ewheels said LK is aware of the problem is they're working on a solution.

I rode with the K262 tire on my Master for about 1100 miles and I thought it was a decent tire, I ran it at about 32 PSI and I'm about 210lb geared up. I eventually changed it to the Shinko 244 which I think is the best knobby tire on the market right now. As far as the foot locks I agree it felt pretty weird at first but I quickly put on some Vertex foot locks and it changes the whole ride, I feel like I have better control of the wheel. That's kind of the beauty of EUCs and pads, you can customize it to fit you best.

You need plugs more than just for beauty. That hole goes straight to battery compartment. It’s a horrible design and kind of makes it structural unless you plug it well. I’m also going to remove those when I get mine.

The foot locks are amazing in my opinion, fantastic for lifting the wheel if you like to off-road and jump.

The pressure written on the tire is actual more about max load which is 267lb at 33PSI and not 177lb.

You could probably benefit from some power pads.

Follow my tuning guide for the suspension, it makes a big difference, your pasture is the perfect place to tune it for your use case.

267 lbs (max load rating of tire) - 90 lbs (Lynx's weight) = 177 lbs. (max rider's weight)

That's true! Didn't think of that, then I am well past the rating.

my few cents I am running kenda on 24 Psi - at 33+ psi kedna is too hard/pointy, makes my wheel fall on turns. 

I take those values on tyre like recomendation. I broke rim already on t4 and on master - high pressure is (unfortunetly) not a solution against rim damage.
