Good point. Whether the leansteer still uses wedges isn't clear from the manual. Maybe the lower section of the leansteer is keyed to the shaft, or at least properly aligned at the factory.

From page 19 of the manual, it appears that there's enough play in the bolt holes to allow some adjustment. Page 20 says to swing the LS to each fender and make sure it returns to vertical, but doesn't say what to do if it doesn't.

If you can't return it to vertical by means of the bolts, I'd suggest taking it to the dealer in Edmonds to see if they can help you. I hope it just needs a simple adjustment.

Of course, you could look at the User Manual on the Segway site. From looking at that, I don't think that the problem description - "the lean-steer frame now leans to the right somewhat at idle/off," - is a simple matter.

DaiPlusPlus -- didn't your SE come with a User Manual? If not, you can download one here:

I hope that I am wrong, but because we haven't heard from DaiPlusPlus in three days, I suspect that he/she just isn't going to say anything about this.

Sorry, I've been busy for the past few days and I was reformatting my computer yesterday.

In response to the questions raised:
  • what happened? - I think the main cause was I wasn't being careful given the terrain conditions considering I was doing 15kph. I'll walk by the fire-lane and post a photo shortly. I think one wheel contacted a stud and the other kept on moving, and the sudden shock threw me off.
  • Had you previously used this route through the fire-lane, before you went through there at 9-11 mph? - No, I hadn't.
  • Details of what the Segway did - The right-wheel struck the concrete which jolted upwards and I fell backwards, the Segway continued moving forward for about 2-3m as it stopped.
  • "He may have not seen a hidden obstacle" - Yup
  • "he may not have seen an obvious obstacle" - Possible
  • "He may have hit a tire on the side of a curb" - There was no curb
  • "He may have been plucked off his segway and dropped by aliens for all we know" - This definitely happened. Honest to God.
  • didn't your SE come with a User Manual? If not, you can download one here: - With the SE, the manual now comes as a PDF on a USB stick. The manual does not make any references to the LSF being out of alignment (the frame now attaches using bolts to shorter, unremovable, frame attached directly to the main chassis). There is no problem with the bolt attachment, it's very firm.
  • If you can't return it to vertical by means of the bolts, I'd suggest taking it to the dealer in Edmonds to see if they can help you. I hope it just needs a simple adjustment. - I contacted the dealer in Edmond and they said they can realign it for $40 (wow!), I meant to go this weekend but I was too busy. I'll drop it off at some point during the week, probably Tuesday.

Of other concern, that I mentioned in my original posting, was that the InfoKey's power button no-longer "clicks" - interestingly the secondary InfoKey (which wasn't with me at the time) also doesn't click either. I'll ask the dealer if it's something repairable too. The InfoKey on the Segway was also thrown-off when I fell off it, but it landed on mud, not concrete. The keys seemed sturdy to me, I don't know how falling onto mud would make it stop clicking.

Ah - Thanks for the information.

Just a suggestion - when going through somewhere you haven't gone before, it's good to take it slow (but keep up momentum). In particular, grassy areas can hide surprises - holes, puddles obstacles, etc.

And I think many of us are curious about how the "alignment" is done, if the dealer will show you. (As you said, the manual doesn't admit that the problem could exist).

Dai++,

It has been my personal experience that the metal buttons themselves of the infokey can pick up some minute debris, and cause them to stick or not go in and out easily.

The return spring inside the infokey is a small flat piece of spring metal, without great force.

There is a possibility that the mud got into the button itself, but if you have another, it is also possible that the feel of that button is simply a bit different.

I have my original infokeys from summer of 2006, and the early ones were ever so slightly different so I cannot offer direct data.

Also, of course, other folks may have had other problems with their infokeys.

If you look carefully at the lower section of the LSF, does it appear to be tilted? And can you see how it's attached? Is there a bolt through that section, or anything under the insert?

Have you tried swinging the LSF to each fender to check for slippage?

Please let us know what the dealer does to realign it (and how long it takes him). $40 sounds excessive to me for what shouldn't take more than a couple minutes. If they charge that much for what turns out to be a quick fix, you might want to rethink having them operate on the infokey. After all, it doesn't need to click!

Attached is a photo of my PT against a wall, the LSF can be seen leaning to the right by a few degrees (the weight of the attachments on the handlebar has no effect; the coil around the base is my security chain, again, it exerts no measurable force on the LSF).

Also attached is a photo of my two InfoKeys. The left one was on the PT when I fell off, the screen won't turn off (thus draining the key's battery). It started displaying the "E012" code from Saturday onwards.

update apparently the E012 code is what happens when you use two keys at the same time, and is unrelated to the alignment issue.

I re-visited the fire-lane today and took a photo. The recent track-lines you see in the grass was my PT when I visited then.

This time, I rode on the lane very slowly and the first thing I noticed was how bumpy the whole area was - not just caused by the concrete retention system (which you can almost make-out), but there were hidden clumps of soil (covered in grass) all over the place. I was going at about 8-10kph and I felt if I went any faster I'd get thrown-off. I followed the same route as before and I was careful to avoid the concrete soil retention system and so given this, I don't think my Segway "hit" anything before, instead I think I was going too fast for the exceptionally bumpy terrain and I hit a bump-too-big and was thrown-off accordingly.

The behavior of a Segway when encountering bumps is "interesting". It will (naturally) try to maintain a steady speed, which is what you are telling it to do. But suddenly it is going downhill or uphill. Or one wheel is encountering different terrain than the other.

That's particularly "interesting" if the rider sees the "level" grass, but the Segway is experiencing different invisible terrain.
