E-S Stealth Electric Bike Owners

So first off I peddle 90% of the time because I want some exercise. Also, I don’t want to be “noticed” or stand out in the crowd because I ride many shared and group trails. This includes paved, rock, chat and dirt trails. Also when around people I’ll keep my speeds down around 15 to 22 mph. On busier streets where I’m safe from cars (on shoulders and dedicated bike paths to the side of the road!) I’ll limit speed to 28 to 30 mph. If I’m riding with cars then I’m the fastest one in most cases. My bike is very fast and it keeps me safe. Unfortunately a comfortable cadence on my bike stops at about 23 mph but I can keep up to about 25/26 for a short time. Yesterday I went on a longer ride to some really good single track trail systems. It’s about 8 miles to the Katy trail from where I live now. About another 4 down the Katy Trail to the good spots. It was a beautiful day (87 degrees, sunny and low humidity) and the trails were packed. The ride included some really slow spots when I couldn’t get passed the crowds. On the way home I really opened it up for the last 6 miles or so keeping 45 to 55 mph down the service roads and 30 to 35 through the subdivisions. My motor with ferro fluid/Hubsinks and this new amazing 24f controller pretty much never gets hot. It’s like Nucular has some magic in their controllers that no one else has. I only have about 350 to 400 miles (the controller didn’t save settings once after some rides and had to start over!) but I’ve never hit 100 degrees celsius even when riding it like a dirt bike. My ride yesterday that ended up being a 35 mile trip and took just over an hour and a half with 52 Wh/mi. On flat ground sitting upright it takes less than 35 amps to keep 45 mph. It takes about 45/50 amps to maintain 55 mph. I need to get a new go pro.

I hope I gave you the info you were asking for?

Tom

Interesting info!
I like to pedal as well. That's one of the big reasons I like my bomber. Based on your screen grab looks like you using 53 wh per mile which is a bit less than me. I do regularly have to push my bike up a hill because its crazy seep and loose so makes sense. Its really cool that your controller shows the max phase current. Is there a corresponding screen for max battery current? or is that "Max power"? Did your old controller make your motor overheat on the same conditions? I too have ferro fluid and heatsinks.. I still would like to make it cool more. And when the motor gets that hot the controller isn't that far behind. The Caps on the stock Clyte controller are 105 degrees so im guessing that if they go past that temp its no bueno...

I just bought the last 24" hook worm on the earth. $57 shipped sheeze.

I have the Nuc set at 250 amps and with voltage sagging to about 70 gives the 17 kw. For the record I have never pushed my bike up any hill. Not saying there are not some that it can’t climb but I will say I’ve climbed a few I could not walk up. I’ve been riding off road for longer than I’ve been riding.

For what ever reason with the MaxE maxed out at 14kw the motor would get hotter than it does with the new Nuc at 17kw……but never over heated because I wouldn’t let it. I have a 3.5T motor. I’ve noticed the higher turn motors definitely get hotter faster than the low turn motors. Years ago I did a 6T Mxus because I wanted an off road bike good to about 35-40 mph. It always felt like it was on fire on anything over 25mph no matter what the settings. I wonder what turn your motor is now?

Tom

adaptto is old and would indeed heat up my motors. I dont have this problem at all with NUC.

Now days old means more than a year old. If I order a Nucular controller by the time I get it everyone will be telling me I should have got a new Quantum controller.

My motor is a 5304 so its a 4 turn. Before I had ferro fluid and hubsinks that thing would overheat on easy peasy riding fire roads.. Now its much better... Some of the Hill climbing im doing I must admit are beyond the scope of the stock bomber power for sure... It's a bummer that we cant hit up some trails together! I need a riding buddy!
I always wind up riding alone because my bike is either way too powerful for other ebikes or not powerful enough to ride with ICE dirtbikes.
Tell ya If I could get it to run at 5-10 degrees less that it does right now with the stock controller... That would be pretty amazing.
The 2 big things that are holding my bike back right now is rear suspension and overheating. I'm going to try some cooling experiments with additional Ferro Fluid. And possibly other means. I know the Grin guys say that using more does not gain anything but I have a feeling for my type of riding it may actually help..
I did run into a guy on a re-geared SurRon X the other day on a local trail... I can't wait to ride with to see what he can handle vs me. If I had to guess I would say that on flatter stuff I would have him covered. Also range I defiantly have him covered but when it gets to proper hill climbs I think he's gonna have me we will see... Too bad we can "re-gear" our motors...That would be an easy and cheap way to change the character of the power.

I think you can still buy them from Stealth for twice that price if you’re keen.

What’s the problem with tyre makers and 24” sizes, they are seriously on the decline for a decent width street/track option. I can’t get holy rollers, crazy bobs, or hookworms…….it gives me the sheeeetz.

Yeah, and you can't find the thick 24" downhill tubes with a Schrader valve. At least the regular thin ones are still available.

I could use a riding buddy also. I’ll betcha (at your cost! ) that when you go to a Nuc 24F that your motor will run cooler. I’m not sure if your phase wires, windings or physical mass will allow it to run what I’m running on a QS motor but you will definitely run cooler than you are now.

I’d say my rear suspension is dialed in as well as it can be for the boat anchor out there but I know something could be better…..I just don’t know how much and at what cost. I would gladly pay x amount if I “knew” shock “Y” was better by even 10% but I don’t. Name brand rear coil shocks are crazy expensive even used. 400 to 600 used is just crazy and to what extent are they better or if at all. For mine my front forks could be better. A set of Fox 40’s or something similar (?) should be great but then the price is 1200 for used and just over $1800 for new…..takes the fun out of the purchase. What are you running again? Can’t see in the picture.

As far as re-gearing our motors, that’s what pumping a butt load of power into them does. I know I can’t do a long, slow, steep trail at high throttle without toasting/burning my motor but I can do it fast without any issues. I can not imagine what the guys pushing 20 to 50 KW into a motor feels like but if it’s exponentially better than the 14 I used to push vs the 17 I’m doing now…….magical comes to mind. I know at one time you mentioned ordering a Nuc 24f. If you haven’t done so, do it. Since you, like me, really enjoy riding it will be the best money you have spent past buying your Bomber!

Keep the pictures coming.

Tom

yea im hoping it will run cooler.
My suspension is pretty good but I want it better. The front end is pretty damn dialed in its a set of Marzocci 888's CR's but the internals have been completely gutted and replaced with Avalanche Racing internals. I've never been a fan of mountain bike forks because the internals regardless of brand are cheap plastic for " lightness". and getting parts is annoying if not impossible.

http://www.avalanchedownhillracing.com/

The rear shock is the stock DNM but I have a spring made by Cannon Racecraft because the spring rate was wayyy to high for me. I had the shock re-valved as well. Which helped out a lot but still not where I want it to be. The nitrogen levels and oil levels on our shocks are all over the place (cheap shock). I'm in the process of getting a race-tech G8 made. Once I have it installed I'll let you know how it goes. I'm hoping it will track better. Someone else with a bomber got it done with apparently good results he rides more motocross style. I never spoke to the guy.

I changed the phase wires to 10 gauge. So that should be good for higher amps. Can't get 8 gauge through the axle unless I do some machining. If the wires get hot I may run 8 to the motor and keep the 10 going through the axle. Supposedly the 5304 is a beast that can take some serious heat. No where near your QS but should be decent.

What are the specs of your battery pack? Mine is 72v 35AH Samsung 50e (140 of em) which If my calcs are correct gives me about max 68.6 max continuous discharge and 102.9 Max (from the pack not phase)

I meticulously built my own pack. I have a 20s15p 30Q pack (8g leads with copper bars and 8mm connectors) that is still pretty new. I’m think I should probably build a new one out of the 21700 cells that are 35 amp cell and 4 to 5 amp each. A 20s10p of those cells would just amazing. When I was pushing to a 200 amp limit the pack wasn’t even feeling it, at 250 amps it has never even gotten warm.

Tom

Nice looking pack Tom. I’m too scared to take my old Dyson battery apart to repurpose the cells.... I just know I’d end up shorting something.

Tom that battery looks like a monster.
What’s your range like off-road?

My bike parked next to my sons brand spankin new Shelby Cobra. He even let me drive it.

At 55 watts a mile I should be able to hit close to 60 miles at high bicycle speeds but I’d guess on a pretty aggressive off road ride I could easily get 35 miles.

Tats,

Thanks for the compliment! Once you get past the first spark, it’s no big deal. It’s just mind over matter, if you don’t mind, then it don’t matter!

Theo,

Cobra is cool but not as much as your bike! You should probably let your son ride your bike…..just once though!

Thanks Tom, as far as I'm concerned you're right. I was never into cars anyway. but on top of everything else, he's got his own B52, and that little piece of red car at the top left is his year and a half old ZO6 Corvette.

If I was your son I'd off both of those things and buy a Model S Plaid. In a bone stock car Jay Leno just laid down a quarter mile run of 9.23 155mph at Fomosa Raceway.

Bro, the new tesla does not even have a descent steering wheel, how the hell will you drive that thing. It is Only good for self driving. What a let down.

It is a better looking car than a Camaro he had, but I like the quality of the Camaro more. Is it on credit?

if pictures flattened butts like they do hills the porn industry would be very sad...

Tom,
45ah battery pack that's pretty badd ass...

The dealership wouldn't let him pay cash, so he had to finance it, but when he makes the first payment it'll be for the whole amount.

Man you have a good memory Allex. I was thinking you must have him confused with someone else, but I just remembered he did have a Comaro ZL1. I think he got rid of that one for the Vette. He goes through so many cars I can't keep track anymore.

I finally got my f37. Man this thing is fun! Unfortunately after my first ride, I realized my charger isn’t working. So waiting on a new one from Stealth. Amazing customer service btw.

Just curious if anyone has a FB group for these bikes? If not anyone want to join the one I started? I don’t really care to own or moderate it but it would be cool to have a little community to share stuff with. Other than on here of course.
