I'm lovin the resurrected HS4080:

Although I don't get great range from it compared to my Leaf...it can just handle big hills faster...and for now keeps cooler since I haven't yet added cooling fans to my Leaf.

I'm still seeing the axle nuts loosening though. The torque block mods will stop the wheel/axle sliding out the rear, but they don't stop axle play. I need to try that trick with the feeler gauge still.

Cheers

Hi,
I'm hoping for information and after reading most of everything in the stealth area hopefully will help me ask the right questions. I have had a Bomber for a little over 4 years and in that time have replaced pads, rotors, and tires twice. My bike has been rock solid as to and from work vehicle 3 seasons of the year. I had thought to completely overhaul it this winter but circumstances have changed as my charger died a week ago and now I need to decide how to move forward. My questions are as follows:

1. Has anyone designed a charger that can be incorporated into the front of the battery compartment and wired in so you only need to carry a power cord?
2. As a 240lb rider I found the motor was amazing new but a little sluggish over time. Is it more practical to try to have it rebuilt or source a new one with equivalent specs or better and if so recommendations for a rider that pushes his bike to its limits half the time?

I'm mostly hoping to get options above and beyond just ordering replacement parts from stealth. If there is a better way I'm genuinely interested. Thank you for any help that you can provide.

In regards to above i dont think charger in frame is possible space wise.
Heres the right one u can buy http://em3ev.com/store/index.php?route= ... uct_id=127
Hub motor shouldn't wear out,its only what feeds it does.
I c ur thinking though.

Here we go again more fun

Thank you, so essentially a new pack is all that's required. I have some research to do then, while reading through the threads I saw that packs can be built with greater capacity in the same physical space. Is there a down side to these or are they simply a plug and play upgrade?

This pack will be 21Ah and half the weight of the stock one. Price is about 1500usd
You can use your old charger, just plug and play.

Could even do a 27Ah cost is around 1700usd
42Ah is possible but then we need to swap out the charger and it will be really tight!

Allex can sort u a pack, depends how much £ u wanna spend,
Are u still getting good distance out of ur original battery?

My range is significantly decreased but to be expected. I'm just over 120 charges and just under 32k miles. Might get just over 20 miles on a charge at this point at speed.

I have successfully installed a MC tyre on the rear of my Bomber and the weight added with this Maxiss Maxcros 70/100-19 is only 1Kg:

During the first ride I reached a top speed of 84Km/h checked with GPS and before the change I was doing about 90Km/h with OVS =3.0°

Uhm 115cycles and 31103miles is 270miles/cycle
and
30405Ahr/115cycles is 264Ah per cycle.

Something is wrong here. Maybe just Cycle count is not correct, as with 31k miles you should have around 800 cycles.

I was doing the math when you asked, a higher charge count would make sense as I charge over the winter as well as I don't want the battery to sit dead

Re: Fighter round plug type to motor

Post by Emmett » Oct 01 2015 4:10am

Hi Guys.

What is the name of this plug type?
Is is possible to repair a broken connection inside? Or is it permanently crimped?

I've obviously not tried yet.
I have a fault in there.

Caught the loom on a stick or something on the trail. Had to happen one day I suppose.

Phase wires can self unplug, but this baby has the clip lock is it got pulled real hard. Seems wobbly and broken.

I was just thinking about re-routing them above the BB. Damn it.

Thanks in advance.

They are known as Mini XLR 5Pin.
Here's one for you:

It's a good thing they are cheap. :)

Oh and they are a B*tch to solder!

Awesome. Thanks CD.

I'll go to Jaycar tomorrow and try buy a pair. Not looking good in their catalog though. :cry:

I'm pretty sure the female one (in my pic) is the one with damaged wiring behind it.

Hopefully I can work out the colour to pin combos.

Two questions:
If I guess the pin to pins wrong, and do a test (give it a little throttle), will I damage something?
Can you recommend a better plug type for the temp sensor wires?

What, these are microphone plugs? That's handy to know.
I would recommend finding someone who is very skilled with a soldering iron because not only do you want rock solid reliable joins, but if there is any solder contact between pins you can kill hall sensors in the motor, I did and it was a world of pain. It's very did fly and no second chances if you get it wrong.
For added protection I also potted my connectors with quick setting araldite after soldering, but there is potting glue available apparently.

This really is the Achilles heal of the fighter wiring and if you can re-route it please share pics, I'm even more dubious now I hear it is a microphone Jack, have to go easy on the creek crossings.

Last rear puncture I left the wheel on the bike and pulled the tube out to fix it, I just did not want to mess with the nicely sealed up connector, it's a sure bet that's where gremlins get in!

Now that's handy to know too. I've got a bad feeling I could have shorted something when trying to make it work to get home.

Perhaps my bike will be out of action for a while, just when I have some ride time available. Argh!

Here is my old connector on the left, just use a small iron tip and you will be fine
Now I would not recommend resuing them as they are not waterproof, just google for "waterproof connectors" and you will get a tons of alternatives
