Hi guys,
Hopefully I'll be a B-52 owner very soon.
Could you guys help with a couple easy questions?
I am looking at whether to get a 2014 (4500W) one or a 2015 (5200W) for a LOT more money.
1. Is there a noticeable difference on torque/speed?
2. I know the 5200W display is bigger but does it do much more?
3. Is the motor the same (other than they added a thermal sensor)?
4. Is the speed control the same?
Any other differences I should know about but am not asking?
I really appreciate you guys' input.
I would probably upgrade some things over time but don't want to be limited by something that can't be upgraded easily without a lot of $.

You might have just bought yourself a spare of the same winding.
No I've not spun it up yet. I knew it might be a H4065 before I bought it. That would be fine. I think it is a H4040. Shall find out later this year.

That's a tough one Jet. Here is my take for what its worth, get the 2014. I say this because if you get bit by the Stealth Ebike bug like most of us have been, you are going to want to modify your bike down the road whether its a 2014 with the CA putting down 4.5kw or the 2015 with the DC1 putting down 5.2kw. The DC1 Stealth now uses is better and more user friendly then the CA. It modulates DC input into the controller correctively quicker and more precise than the CA. I don't know how it compares to the CA V3, but this is the case with the CA V2. If you are a tinkerer, you will like the CA better than the DC1. CA settings can be accessed through menus and advanced menus where as the DC1, can be if you know how to :wink: but it will void any warranties and the diagnostic screen will show that as well.

Fix,
Thanks for the reply.
I probably could have found a better place to ask the questions.
I suppose the AC and DC etc are the older and newer displays.
Do you know if the motors are the same?
Speed control the same?
Thanks again,
Erik

For 2014 and 2015, both motors and controllers are identical. Top speed should be the same, the 5.2kw Bomber should get there just a hair quicker than the 4.5kw Bomber, all else being the same of course with rider weight, wind conditions, temperature. Whether you go with the 2014, or the 2015, you cant go wrong.

I don't think so...Rick (Fix) :) is undoubtedly the best man to answer these questions...he's owned both CA type and DC1 type...and the difference between them is pretty interesting! I think the thermal rollback is a great new feature...not to mention the absolutely incredible new packs...minuscule sag and deep reserves but either one's the best choice for different reasons...the older model being obviously excellent value for money.

Thanks to all of you who responded to my questions. Very much appreciated. Now if I can get the seller to send a picture or two.

Oh yah, I did forget to mention the thermo rollback, and also, if the 2015 comes with the next generation battery, get it, even if the price is a few grand difference. Yah the new Bomber pack is what, 20 or 21s and 30+Ah? And a heavy duty rated BMS capable of north of 100amps. Hard to beat. Thanks Remf for pointing out what I left out.

Also worth mentioning MT5 brakes on the 2015 which are a big step up from the MT2. And the DNM front fork that have been re valved and tuned to Stealth specs.

If i was going from a 2013 to 2014 bike, I would go with the old model just because there really wasnt that many changes. 2014 to 2015 is a different story though and has been a big development year for Stealth. No right or wrong desicion here, just need to consider all the facts.

Really? Next gen Bomber batter is 30+ ah?

Yah, Kepler, I should have thought a little more about my response to Jet. 2015 Bomber was a ground breaking year. Sort of a model overhaul.

Yah, Remf posted several pages back that he got the next generation battery for his Bomber, went for a long ride, and consumed 35Ah and still had a little left. Not surprising as battery tech is improving every year.

My understanding is the Fighter battery has had a significant capacity increase or is about to but the Bomber battery cap stays the same for the time being. As mentioned by Rix, the big difference with the 2015 Bomber battery is how well it holds voltage and gives you consistent performance across the full range of the battery.

Speaking to Joe at Stealth last week he was getting up to 120km of a prototype Fighter with the new battery. Entirely new chemistry. Battery tech is moving in leaps and bounds. exciting stuff.

Wow...that would be my dream to have 35ah. If I could cover a 60 km trip as if I'm riding 35 km trip (hard), that would be pretty amazing. I have to get up really early tomorrow to ride my Mando Footloose in Eco with hard setting series hybrid (pedal power generation) just to cover 35 km at 13 mph. I'm curious how much alower Eco mode is on the new fighter.

I should clarify & emphasise that the 35Ah consumed was over 3 charge cycles...as Kepler said, the capacity of the Bomber pack hasn't changed but the capacity of the new Fighter pack sure has...30Ah of absolute awesomeness!!! It's amazing to go for a ride and finish at the same voltage you started at. Also the new fast charger makes short work of an empty pack. Don't ask me how much the new pack cost...that's the painful part...ask me was it worth it. So worth it.

Yah the Fighter battery has a significant increase in capacity. I misunderstood Remf's post about his Bomber's battery, but still, that doesn't change the fact that the new batteries are performing way better than the older generation. That translates too power to the rear wheel, and a bigger grin on the riders' face. :mrgreen:

Just came back from another short burst on the Fighter and found out that my regen actually does work. I thought it was broken but it isn't...it's just that the new pack has such little sag that it took 22 km before the voltage dropped below 56V, enough for regen to kick in. Jaw dropping.

Hi, I have a current issue with my fighter, after riding for a couple of kms I use full throttle and it works for about 1 km or so the the bike shuts off with nothing on the cycle Analyst. Then I pedal down a hill to get enough speed up and use the re-gen button and it powers up again and I can get another 10kms or so. But again if I use full throttle it shuts down again. Does anyone know of any reasons this is occurring. Thanks in advance.

I think I can say with maybe not 100% certainty that you have a problem with your pack, possibly a fried cell or 2. I would contact Stealth...they can repair it or point you to other solutions depending on your location.

Got to be soon, Stealth can't leave the smaller Fighter as it is with more range potential than the Bomber.
