King Song S18 leans heavily to the left leg


Recommended Posts

My brand new S18 leans heavily into my left leg. I am getting no resolutions for this. Has ANYONE had this? I've raised the pedal on the right side, thinking by putting more pressure on that pedal it might make the wheel more upright. It isn't leaning just a little bit, it puts way too much pressure on my left leg and of course wants to steer to the left. I have over 4,000 miles on my 18XL so I am not a novice. I have ridden it nearly thirty miles. Yes, I can ride it but it should not be like this. Any ideas?

Are the angles of the pedals the same?  Not backward or forward tilt, I mean pitch.  I would think if the pedal angle was different it would lean to one side when standing on both pedals.

When you say leans, what leans? Is the wheel and tire leaning. ( closer to one side than the other) Does one pedal sit more flat? Can you see something that is off?

My S18 also rides against my left leg.  In my case it has to do with how the rim/motor is centered on the vertical plane.  On my S18 the tire sits closer to the Right side of the wheel - R side if looking the same direction as headlight, like when riding - or the L side when facing the wheel.

I'm not sure, but I think it's a dual issue in my case.  I think the rim/motor is to the right side, but I think it may also be at a very slight angle (lean).  It is my understanding these issues can be fixed with shims, centering the axle where it sits - but I have not attempted this repair yet.

No idea if your S18 has this same issue - but I fully admit, I rode my S18 a while before noticing the lack of symmetry - then once I noticed it, it was really pretty obvious.  My fender is also tweaked, so this photo makes the issue look worse than it actually is - but clearly the tire sits closer to one side than the other (and the tire spins clean, without any wobble).

I did send my S18 back to eWheels to be serviced, but honestly - I couldn't tell much of a difference when I got it back, and the problem is as bad now as ever, including an annoying tire rub.  Whatever fix occurred did not last very long, and the wheel settled back into the same shape it was when it arrived, new.

I haven't been in a hurry to fix the issue(s) myself, because my wheel does work, despite issues.  I completely understand the frustration of a new S18, that feels less than new - but interestingly, I ride my S18 a lot, and generally enjoy it when I do

That can be fixed with shims but it is not as simple as some might think. Adding shims to one side of the EUC doesn’t really do anything. You have to add shims to change the angle that the axle sits in the Clamp. So you add shims to one side of both clamps. ( right or left of the clap itself) The goal is the change the axle angle in the fork  If you ad a shin to all of one side the suspension compensates for the shim.  To be clear, if you add enough shims to one side it will eventually fix the problem but we are talking about shims that are millimeters thick rather than 0.02 mm thick.

if there is a video of the S18 motor/rim being shimmed into center - I'd be interested in watching it.  I think I've read two or three explanations, and I understand what you are saying, but some video would really help clarify the process

Yes, the pedal angles seem correct. Thanks
