Did you ever wish your BBSHD went substantially faster, pulled harder and you didn’t have to be told you can’t buy the controller you want – shush it’s a secret?
Well thanks to a very clever friend of ours, we are the UK and EU distributor for this exceptional device.
This controller has everything: field weakening (allowing higher rpm), set maximum amps, set maximum watts, maintain these figures while volts drop, Bluetooth, totally plug n play and potted to 100% waterproof.
Advanced processing and state of the art allows it to compute much faster and much more accurately than the standard Bafang unit (or any modded Bafang controller). Imagine your first media phone in comparison to the latest Iphone/Android device? – Things have moved on and these Canadian devices have not been designed with penny pinching mass market sales like the original. All of this makes your 52 V motor pull much harder and release around 15% more speed than a 50A Bafang controller and whopping 100% more power than the standard, while still using your standard display! (NB, please see our note about displays). We might add the power is designed to come in without the mechanical snapping lurch of an inferior set up.
These controller have been set up so that it can handle anything from 50 A up to 3250 W (easily within their design).vThis might mean a little explaining:
We have tested the BBSHD to destruction and on more than one occasion right up to 4500 Watts and learned a few things, real facts and not the odd exception.
Amps create heat, heat weakens the nylon gear and too many watts snap the pinion. So how do we get around this? Simple, know the limits but don’t get too close. Sure these are now nearer the limit, but ridden correctly (let the motor spin and don’t labour in the wrong gear), a reliable ride can still be had. At the lower volts where big amps are needed, we have capped the limit to 50A but as you increase your volts, we capped the watts to 3250 W. A ludicrous controller at 50A has 2500Watts – so does ours, but now add 10 -15% improvement through field weakening!
But here it gets even better, Change your battery and go up to 20s 72 V (any voltage form 10S to 20S, 36V -90 V) and the controller takes it (not a Bafang originated 60 V cap). Your watts have now jumped to a dangerous 4200 watts on a “hot” (fully charged battery at 84 V), so we reduce this limit to a safer 3800 W, but still so much powwweeeeer!
When more funds for a bigger battery are available and you decide to go over 59 V with the same unit, just add our 750C display and suddenly 45- 50 MPH is on the horizon and full PAS function!!!
PAS 9 levels (in watts):
1=60, 2=120, 3=210, 4=330, 5=480, 6=660, 7=870, 8=1110, 9=1500 (throttle full power)
We uploaded a video of the full working prototype. Note the cover of the motor and display are for this video only. An existing Bafang wiring loom will be used.
Take a peak!
DISPLAYS, a painful note.
Unfortunately not all displays are equal. Bafang released a myriad of display, and different firm wares. We are a small company and haven’t managed to test all of them; but what we have found is that all the original displays still show everything (time, speed watts etc), but will not allow PAS. You can still ride your bike with the standard display on throttle only.
But, if you include the 750c display that we list, full PAS is restored.
How you budget your expectations and wallet is up to you. You can buy the kit without the display and see if perhaps your display gives PAS (we cant help here as there are too many combinations) and if not buy separately; or you can buy the kit with our display included and everything works.
With exception, we think the Standard 750C display will still give PAS on 52 V (up to 60 V) set ups – BUT NOT work over 60 V (ours are physically altered).
