This is what I've accomplished after all day. This taillight bracket only cost me about 0.34 cents to make, not counting the rejects, but if you want me to make you one it'll cost you $750. :o

I liked it better when it was hiding up under the seat, but I guess this will do for now

Before and after look at my taillight mounting, and dropper seat post. All other things being the same, the seat now sits 3" higher in the saddle than before when all the way down. I can still touch both feet down at once, but it's only because my big fat a$s squashes the shock down enough to do it. It's uncomfortable though. One foot down is comfortable. Still haven't attached the cable yet, but it feels like I'll only need about 2" of the 4" of lift.

I finally finished installing my dropper seat post. I haven't actually ridden with it functioning yet, but I rode about 20 miles with it all the way down. Being 3" higher feels different to me, but I think I can get used to it.

I ran the cable through the frame, but I used an external seat post to do it. The cable is out of the way, and looks pretty clean from the rear. The front was always a mess.

This is the other end of the cable. You have to cut it to length.

It's hard to see much difference from the front, it was already such a mess anyway.

I rode around a little bit just now testing the seat in different positions. Just like reviewers say, it's very easy to control the speed of the up, and down on the fly. It feels like a hydraulic office chair. If you unweight your butt a little bit, the seat helps you up. With your weight on the seat, it's easy to control the downward speed, and height. Slow, or fast, it's up to you. There is a tiny bit of side to side rotation, but it's barely noticeable riding.

The seat all the way up is a little too high for me. Down about an inch is perfect pedal geometry, which means there's about 3" of travel I can use realistically. Now I can pedal hard without killing my knees, and still be able to drop down out of the clouds for stops, and dismounts. I think this would be a popular option if Stealth offered these for new bikes.

The only thing that's not perfect, is that the lowest seat height is about 2 inches higher than I would like. I'm going to have to try to get used to that. One thing this seat post has is a, high snotty snoot factor, so there's that.

I rode downtown last night to the critical mass ride. 40 miles round trip, not including about 10 miles on the train. Everyone was real entertained by my moveable seat. I'm getting pretty good at working it already, but when it's up, I got to remember to drop it down before I come to a stop, or it gets interesting. I'm noticing that my knees aren't sore today.

Super cool Theo.....since I’m 6’4” tall I find I could really use the extra height of a dropper seat post and, of course the prestige!

Cool posts!

Since I can lift my seat up to pedal better, my plan last night was to leave early, and pedal all the way downtown, 20 miles with no power. With only 19 2/3 miles to go, I finally gave up on that stupid plan, sheez :(

:lol: thanks for the laugh TV
Wouldn't want to do that on purpose.
I've done a 11 mile ride of Shame when I first got my bike.

There's a lot of good bike riders in Ohio. Did I mention I was born in Ohio?

This is all the way both directions. I have about 100 miles experience evaluating this dropper post now. Even though they're not specifically designed for motor bicycle use, motor bicycles are a perfect application.

Does anyone know if a heavy stealth rear wheel tends to need, faster, or slower rebound damping?

I'm guessing that because of the weight, you're going to say faster?

I tried faster and it nearly killed me a few times when launching off jumps and large humps. I've since toned the rear right down to a medium/slow point which works well enough and doesn't try and kill me.
This is for off-road riding mainly though...if I were only on the street like you a faster rear makes more sense. I still wouldn't max it out though as you would still be dealing with speed bumps and curbs, etc. A medium/fast setting would probably work well for most street.

BMS wiring done.
Very happy with it, Bluetooth settings and PPTC fuses added to the balance wires at cell ends, connected and sitting next to the neg sides of the battery cans.
got the 150A continuous version although next time i'd just get one that does minimum and simply bypass for discharge.

Very happy with range and performance, next time around i'll glue the cells together and fit an extra row in there and another set of 22 ontop hence should be able to fit 22S12P vs 10P I have.

All said and done have almost double the range a stock bomber had back in 2014. All in probably 24 man hours work, which I reckon i could halve with some practise.

Recycled all the original power cables and fibreglass sides that were on the original battery but they are all substantially trimmed down.

Height at 2.5cm for the BMS IS A PROBLEM - cut down the stock foam under the back by about half for the win.

Nicely done Karl.

If you can build these in 12 hours each I may as well give up now. You could be onto a winner if you were willing to sell them.

Maybe I'm too meticulous, but my packs typically take 30-60 hours to make. Hence my pricing that many can't stomach.

Cheers

Thanks for your comments about adjusting the shock CD. That agrees with what I was thinking.

I started out in the middle, then tried 3 clicks slower, and 3 more clicks slower. I rode it like that for about a year. Recently I tried 3 clicks on the fast side of the middle, and decided it rides a little better. I reduced the preload slightly, and it feels softer riding that ever before.

The combination of my Fastrace shock, and these new Fox forks have transformed my bike into a really comfortable ride.

The cell holders and using Solar panel bus tape and solder saved a heap of time over glue and spot welding which i've done before and yes thats painfully slow and mistakes unforgiving (take it apart again potentially damaging cells etc)

As for making them commercially, like most things - better with practise. the extra time to make the pack bigger is enormous and we're lucky that 3500mAh cells are available and basically inexpensive.

If your soldering and using holders then there's hope for me yet.

See how long it lasts you, but I don't think there's many around here that will think soldering 18650's is a good idea, myself included.

Good luck!

About 60 hours is the time I spent when I built my 20S14P battery last year and used a spotwelder as Cowardlyduck.
Today after about 57 cycles it is still ok and considering that often at night I cover a few km at full speed at about 100km/h (10-11kW) I would say that I can be satisfied with the result.
