Sorry if i rant, but ive only just been told about this post - cant normally be bothered or have the time to lookly through this.
So much bullshit and guess work or just sales shit from a silly man that compared the BAC 800 to a slightly upgraded BBSHD because he can only sell the CYC standard controller.
Hes not the only person who speaks regular to Jon at CYC and im not going to name drop or or play "he says they said", nor am i going to spend my time rubbishing another controller from them.
In all honesty the 52v from cyc is probably the best budget option out there. But dont make me laugh that a sab is in the same league as ASI!!!!
But here me out.
I am the biggest UK BBSHD seller for the last two years.
I already have three cyc motors and more coming.
I make no more or less profit form either although I can get more BBSHD to sell, so really if i were biased it would be to the BBSHD.
I have an open line to ASI BAC and can buy choose any controller they have or want at trade prices.
I sell Sabvotons (well ive just stopped because Im sick of them: 1 left).
So why do I sell the BAC 800 for a BBSHD upgrade and recommend it for most cyc buyers?
Because it works really frocking well!
The BAC 800 is small and advanced. It's waterproof and super reliable. It has advanced FOC not the bbshd shite that people mod (I have a Luda at 50 A and the BAC murders it! and ive destroyed three of them and the BAC never misses a beat).
the BAC wil run 3000-3500 w continuously depending on temp, but it will easily handle 4500 in long bursts or peak short for 6500W!!!!. I run a 72v 3250 limted to 50A on a BBSHD and with my lardy 270lbs i can easily hit 45 mph with 42T front and 24T rear on 29er Hookworms - try that with a BBSHD contoller or SAB!. But do not have the balls on a skinny push bike to hold it there for long and very much doubt you do to either. This is not a Vector or Stealth frame, they are meant for push bikes - small and light.
So bow many of you are realistically going to put a whacking great 50A + battery on your bike? How many of you can actually buy one off the shelf? and where? If your a lipo user then the chances are you do need a bigger controller and hay presto we are already devoloping the 2000 for that!!
Oh, I forget to say how many volts does the BBSHD go to ? any answers? oh yes its 60V.
How frocking big is a SAb 72060 ? frocking big
How big is a SAB svmc 72100? much bigger than any controller you would ever want to put near a push bike unless its to stop it rolling down a hill.
So here is the answer:
If you want a budget set up and are sticking to 65A at 52V buy the std CYC when it comes out (i will make more money out of you this way, the BACs cost me a fortune).
If you want your BBSHD or CYC to go 72v, be compact and reliable and hit 45mph easliy (BBSHD) and 50+ (CYC) and rocket up a hill because your using low gearing, then buy the BAC 800.
If you want a crazy big or short distance battery buy something else like the BAC2000, but your bike will either die within 15 miles (smal lipo), weigh a ton (big 18650) or rip the drive train apart (more than 4500 watts).
If you have the ability to build your own 21700 battery like samsung 40T, you really dont need this post, as you should know what your doing.
If you really THINK you know it, go drag race a BBSHD at 50A with your skinny wife on it (until the Nylon gear goes) against a strangled CYC running at 50 A when the whole point is it can handle mush more (like 90A peak BAC 800)
If you want to fit he CYC to a heavy EEB frame or Vector or similar - go ahead I have no clue what will happen!
PS forgot to say my BBSHD at 72v with BAC 800 with my overweight 270lbs would murder those two 52v set ups and the cyc at 72v will destroy all of them at 60A.
Why? because a low geared bike will out accelerate a 52v system every time because of lower gearing.
