Checking in, it’s been a while. I am riding sparingly but determined to change that this summer following a hip surgery last year and realizing how much therapy I get from riding Stealth.
I also want to learn more about how my bike works technically. Any advice on good websites / videos to look up regarding electric bike technology and inparticular the Stealth Bomber?
My #366 is still going strong with only just over 500 Miles on it in less than 4 years but I have noticed a drop in power. I guess that’s normal for aging batteries huh.
Incidentally anyone know what is the number of Bombers in circulation these days? Just curious. Cheers, Bex
That is normal for a battery to loose performance after 4 years. My Bomber's battery is over 6 years old now, I got the amps turned down to 40 and it sags to 70 volts hot off the charger. Still working though.

I have never had to deal w getting new gaskets etc. they are made out of a rubber material that is made to be re-used. and even if it broke I would just chuck some silicone or yamahbond in there and call it a day.

As far as getting internal parts for the vboxx its not easy.. Your best bet is to get them from stealth or find someone w spares. Even then its a pain in the ass...Thankfully the internals of that thing are pretty strong. Interesting note, some of the internal parts are hand stamped with construction dates and initials on them...
But am I wrong or are you the one who needed a new gear?

You are correct sir! so trying to get parts through Suntour was basically getting kicked repeatedly in the junk...painful and useless... Stealth was better, So my situation was a broekn tooth on a gear. initially I got the broken gear tooth welded up and I shaped the tooth back to the point that you couldn't tell it from the non welded. While all of that was going on I was dealing w stealth who in turn was dealing with Suntour. Eventually (months later) I got some parts from stealth because they happen to have a Vboxx kicking around.

How the Vboxx repair is technically supposed to work is you take the vboxx off the bike, send it to stealth who sends it to suntour (in Taiwan) they fix it and send it back to you. P.S. you wont know how much it will cost until they see it. I did not want to send mine overseas so i was just going to fix it myself and I happen to get lucky that stealth had some spare parts kicking around.. I wouldn't count on it though..

In your position I would take it apart, see if it needs anything, if it does get in touch w stealth..

Anyone know if DNM rear coil springs are the same internal diameter as Cane creek and Fox?

For the Bomber, no, the spring is different and larger.

I'm also curious to know how he did to completely discharge the battery in 45Km? How many Wh/km?
With the battery that I will replace shortly I still ride 58Km at 26Wh/Km

Anyone know if a fox float mxr would fit the bomber. With the spacer kit (required for the ttr 110) the dimensions look spot on !.e 188mm eye to eye.

This is what I expect from my new Bomber battery that I’ve been building

20S14P Sony VTC6 3120mAh
Nominal values 72V 43,68Ah 3145Wh

Expected Real life values 72V 35Ah 2515Wh
25Wh/Km expected 100Km
30Wh/Km expected 84Km
35Wh/Km expected 71Km
40Wh/Km expected 63Km

I think you are spot on with the estimates. That said, I found it was easy to average about 25wh/Mile when pedal assisting the bomber on flat ground and keeping speeds around 15MPH. I suspect the new battery would be good for close to 100 miles under these conditions, but damn it would be boring as hell to do that for 100 miles.

The trail was i rode was of the worst type with a lot of steep hills. I have tested the new battery when i rode my new bomber along with a friend that has the old battery version. His at some point got drained to 0, while mine had 30% still left. Me and the other rider did excactly the same track and both weight about the same. So the new battery is good :) , does what it says on the box :)

I usually last about 10 miles before I can't take it anymore, and let it rip.

I'm glad they went to 18650 cells. After comparing them to LiFePo4 I prefer the 18650, because they really don't have as much sag, just like Allex said. Seems like they last just as long too, or close enough. Plus you can apparently make a much larger capacity battery with 18650s that will fit in the frame.
