I am going to fit Shamano saints to my bomber b52 and has anyone else done this yet?
I just spoke to a bomber owner who fitted avid code brakes and need to google them now
thx

'13 Bomber, original owner, 3rd frame (works good now with the seatpost bracket re-inforced, thanks Stealth!), ridden 20 - 50 km/day (9 mon/yr) on gravel trails & pavement, dry climate. v3.x Cycle Analyst, I believe?

Mid-ride, this afternoon with 1/2 battery capacity left, the throttle response ceased; toggled the keyswitch a couple of times while still riding (CA's LCD toggled off/on with key position) but still no throttle response. Tried again a minute later and the CA LCD no longer lit up.

Plugged the bike in @home and charging proceeded as per normal.
1/2 hr later I unplugged the charger from the bike, tore off the side panels & fiddled with the connectors - no change.
Found multimeter: measured 0 & infinite Ohms on plug to keywsitch for on/off positions.

Not sure how to proceed, other than dragging it down to the (nearby) dealer.
Can I further isolate the problem @home or will it be a matter of parts swapping until it works again?

TIA

[edit] Rereading this, it could also be the controller. A couple of years ago I had a rare combo fault of both a blown FET and a cell. I had to send the controller and the pack for repairs...I thought it would takes ages to repair but was amazed when I was back riding again a week or 2 later.
Thanks remf; I'll let my local dealer call Stealth, etc. They (Revolution Cycle, Edmonton, AB) are pretty good.

I know I used to have 3 or email addresses for Steatlh that ended in .au and those don't work now. I deleted them from address book and will update as I come across new addresses.

On your crank arms mounting faces, you got an allen threaded cap sized 10mm and inside of the cap is the actual bolt sized 8mm. Don' touch the 10mm cap bolt. Grab yourself and 8mm allen wrench, and some grease and put that on BB outside spindle . Maybe put just a little bit of blue lock tight inside of the bb bracket spindle threads. Then torque it down. I can't remember but it seems like you don't want to exceed 35nm of torque. I have the manual on my other computer and can look up the torque specs tomorrow.

I grabbed an 8mm key from a bike shop today and sorted it so thanks Rix

Its the left arm. That's significant.
If it was well worn inside the square taper it'll probably fall off again in a few hundred km no matter what you do. If it does, look inside the crank arm, you'll see something like this:

If it happens and you need a new arm, you'll notice a heap on new ones for sale on fleabay and alibaba (I have plenty too of various types). If the crank isn't torqued when fitting it slops around until the ally is damaged.
Its counter intuitive, but when fitting a new crank, some lube inside the square taper actually helps the crank draw fully up onto the spindle and avoid the issue happening in the long term...

i bought the Bomber 3 months ago so I presume the arm was not tightened properly at the dealers as I picked up the bomber as a fully assembled bike
so if it comes off again as there was slight wear can I get a replacement under warranty?

This is my 6000 mile Bomber report.

Still running great as usual. My battery capacity seems to be reduced to about 17.5ah. Still tops out about 50 mph, 53 when pedaling.

I have 1000 miles on my Hook Worm tires, and they're holding up better than I expected. The little basketball bumps are worn off the rear, but there's still lots of tread. I think I might be able to get 2000 miles out of the rear.

I'm on my second set of brake pads that are a little more than half worn out.

The only failure my bike has suffered was a right side swing arm bearing.

The only maintenance I perform besides changing tires, and brake pads is occasionally lubing the pedal chain, and VBoxx, and I stuffed some grease into the freewheel once.

I consider this to be extremely outstanding dependability.

Revolution Cycle determined the root cause - a broken solder joint in the connector that feeds from the pack to the controller (under the battery) , thankfully a quick/simple fix!

I tightened up the peddle arm with an 8mm allen key as suggested
and it fell off again last night and looking at it inside its now worn and fooked
so I will be asking for a new one under warranty

Nice update TV, looks like you got another 2 years with your battery. Technically you probably go 4, but you will come to a point where your battery will only hold 9amps and volt sag under WOT will result in BMS shut down, hot of the charge. Than you know its time to replace the battery. :lol:

Just shows lifepo4 is good stable stuff.
My 2012 battery still holding up after i had cells replaced, last owner diddent look after it, i got a good friend on this forum
To put some new ones in
Still got about 85/90% capacity
Look at this little bugger i got this morn, and it diddent even go through inner tube, it came out side wall :shock:

You lucky Jimbo, that could have ended your ride. Yah, you got Bomber 138, I have 143. We both have the same old LifePo4 pouch cells. The new packs are running a different chemistry.

Stealth is using some kind of Lithium Ion chemistry pouch cells. I don't know what chemistry it is exactly, but its not Lifepo4, and they are definitely pouch cells.

Also if anyone has got hope tech brakes
Mine had excessive travel at the leaver done the bleeding thing, so then i tryed the pad alignment vid on YouTube
Well what a difference nice leaver modulation
the pads are now closer to discs so if anyone has them or other brake with crap leaver mybe this would help u out
But u have to get discs dead central to the caliper slot :wink:

It's a great feeling when you get your caliper alignment just right!

Another bit of info with the Hope Tech series is that the Tech 3 V4 caliper is designed to accept their floating vented rotor which is substantially wider than the standard disk or floating-only versions. You should get the best feel with the vented but if you are using a narrower rotor, the system should be re-bled so there's additional fluid in the system to keep the pistons closer to the thinner rotor.

Stealth is using some kind of Lithium Ion chemistry pouch cells. I don't know what chemistry it is exactly, but its not Lifepo4, and they are definitely pouch cells.
I believe Stealth have moved away from Lithium Ion Phosphate(LiFePO4) batteries in the the latest models completely.

I am not 100% sure but based on the current capacity, I think the current Bomber is using Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2 or NMC). NMC is superior in nearly every way over Lithium Ion Phosphate(LiFePO4) has good overall performance, safety and specific energy.

In regards to the new Fighter battery I believe this is using Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2) which has the highest Whr/kg rating currently commercially available. A give away is that the new Fighter pack is a (Edit)14S pack as opposed to previous pack being 16S meaning that each cell has a higher end voltage.

Very interesting info John! My guess was that the new Fighter pack was some type of LiMn chemistry because it weighs around 10 kg and is 1.5kWh. Lithium Nickel Cobalt Aluminum Oxide - like the sound of that - apart from the nasty cobalt :)

It's great that Stealth are updating the Battery packs...it's just a shame they don't update the rear dropout design. Or put bigger axles on the hub motors...or use clamping dropouts...or do anything to prevent what happened to me today:

I've mentioned it on other threads, but on my HS4080 (from Stealth) I recently stripped the axle threads trying to make the nuts tight enough to prevent rotations issues.
I still haven't been able to get my axle repaired, but today gave it a shot anyway. The nuts weren't on very tight, but it still felt solid when riding. Going down a hill I decided to do a bit of regen...BIG MISTAKE!

So anyway, this resulted in the phase wires shorting somewhere in the axle. It must only be a minor short as we were able to pull on the wires and it stopped, so we zip tied them in place and I was able to ride home pedalling.

I'm pretty sure I've mentioned it many times before in this thread, but the non-clamping, horizontal dropouts DO NOT WORK. At least long term and with the tiny 1/2" axle of the HS40xx motors.

I've just ordered a new Leaf Motor with 16mm axle nuts. It shouldn't have any issues, but really Stealth should not be selling these bikes with such a weak link IMO. I've had nothing but problems with mine since I got it...now after 4+ years of use, my swing-arm is worn, my torque blocks are worn, the axle on all my motors is severely worn, and so is my patience with this design...really hoping a 16mm axle helps.
