Ultimate BBSHD, battery and Controller Screen –complete kit with our new bespoke display 72v 25Ah High Output gen3 triangle battery and charger and Gear Sensor motor cover all included!!
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?
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 72 V motor pull much harder and release around 15% more speed than a 50A Bafang controller and whopping 100% more power than the standard. (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). With the use of field weakening and higher volts, the higher RPM allows the use of lower gearing (bigger rear cog), massively improving torque and top speed. Blistering acceleration and genuine 45-50 mph top speeds.
These controller have been set up so that the motor can handle anything from 50 A up to 3250 W (easily within their design). This 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 3250W. A ludicrous controller at 50A has 2500Watts – so does ours, but now add 10 -15% improvement through field weakening and then up the rpm further by going 72V (try that with a a crappie luda controller)!
But here it gets even better, Change your battery and go up to 20s 72 V (any voltage form 13S to 20S, 48V -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 3250W (peak), but still so much powwweeeeer!
This is recommended as a throttle only and single speed (easy to adapt your free hub to single gears) application due to high RPM and low gearing. Your bike will accelerate like a rocket and still hit around 45 MPH, depending on how you gear your bike. You can accelerate faster or have a higher top speed. We find 45 MPH is enough. Bigger explanation further down.
You can still use your favorite pedal assist gear, just don’t use it in the high power settings and we have capped it at 1200watts. This may take splitting the cassette up and using spacers to put the optimum gear in the centre for better chain line, place and the smaller low power gears on the outside. Then the used gears then go on the inside where they are used only as as spacers..
Because of the weakness of the Nylon gear, the use of low gears is necessary and we recommend front 42T and rear no smaller that 28T on 29er or 27.5″ wheels and 26T on 26″ wheels. Smaller the rear wheel, the main rear cog can be reduced in size. So a 20 inch wheel mat be able to go something like 20T rear cog.
We have tested this set up thoroughly with a 250 lb rider without issues.
No need for gear changes (although in low power mode this is still very usable with PAS) as the massive increased RPM range and large rear gear allows blistering acceleration and high top speed. Because of high voltage, low amps are used to obtain more watts. For example 72v x 50A = 3600 watts compared to 52v x 50A = 2600 watts. and we all know that high amps create motor killing heat, we limit the motor o 3000 w.
A 72V system uses less power and generates less heat but makes you go much faster.
The down side? = more money for the more advance controller (advanced field weakening) and the higher cell count battery. PAS is less suitable and the motor spins much faster. Because of the higher RPM a really good chain line is really important: drastically reduces wear and stops chains from snapping.
You no longer need other gears! your weedy legs are obsolete!!
We ship the controller with 9 power levels.
PAS function is available with a choice of up to 3 – 5 – 9 levels via the display. But each of these levels can be individually tuned to your pas preference (each level can have more or less power) Now with Electron tunable PAS display. Wee ship dials instruction with every order.

Independent review from Jamie N
“This battery is a total game changer. 1000 miles in already and it’s just incredible. Seems to stay so exceptionally well balanced like <0.005V max and I’m consistently getting even better range than my mates with the 52V colossus Tesla Panasonic battery one even tho I’m blasting it far more and having even more fun
So so so very impressed with this build. It really is very special”
Weight 10KG
We strongly recommend that when installing the case, a soft pad be placed between the down tube and case (6mm number plate stickers are good). That the bulk of the case be supported on the down tube (not supported solely from the strap holders). In extreme cold conditions we do not advise using the battery.
We use only genuine new grade A cells and made up into complete batteries specially to order for us at our dedicated factory or here in the UK by our in house battery builders. We simply can’t buy a single battery, We have to agree to a production run of at least 20 batteries. The 0.2mm pure Nickle sheet is laser cut and then electronically welded to the cells to give and safely handle this unprecedented “in triangle” huge power output with minimum internal resistances. The UK cases are fabricate here in the UK assembled by us after double checking everything.
We warranty these batteries for 12 months for manufacturing defects..
Space required, please see photo.
Charging: First time charging is VERY important. Always connect the charger to the battery with the charger powered up from the mains. This will stop a “Connection Spark”. The battery needs a “Balance Charge” on first charge. Please charge as above. The charger will display two red lights (charging) after a long period of time (between 1 and 8 hrs – depending on state) the LED charger lights will display red and green. This indicates an initial charge is complete. However, as this is a new battery, not all cells within the battery are balanced (same state of charge as some were higher/lower than others to start with). This is because cells can arrive at the factory in different batches and may have slightly different charges due to time in storage). This is very common and normal. Now please leave the charger connected to the batteries for a further 12 hrs. This allows the internal balancing system (BMS) to balance out all the internal cells. The charge may turn on and off over this period of time. This “Balance charge does not need to be done every time and is recommended every 20+ charges. Leaving the charger plugged in working does not damage the batteries. The charger is designed to stop charging at a pre-set level and turn on again when this level drops.
* Warranty is or 6 months from date of purchase. Due to the nature of use of these devices (off road) warranty is limited to 6 months from date of purchase. Any damage the result of water ingress, alteration may void warranty. This includes shortening of cables and changing connectors. It is the owners responsibility to proof against water ingress and not use in unacceptable very wet conditions or use direct water from hose/washers
Any alteration modification to this controller or its subsequent wiring, even cutting the power leads to make shorter will immediately invalidate any warranty. Even battery disconnected, the controller can still maintain current and can still be shorted/damaged. The controllers are waterproof, but can still suffer from water damage through the connector and hence are not covered for water damage.
Warranties are not transferable.
Please note, Lithium batteries are considered hazardous and due care and attention should be taken. Although these cells are in wide use, and professionally manufactured in a purpose built factory; because of the power of the battery, we strongly recommend that precautions are taken. We do not recommend charging inside the family home and charging should be supervised. We take no responsibility for misuse. These batteries are thoroughly tested (full discharge and charge cycles at the manufacturing stage and also pre-delivery). These are not DIY or amateur built devices.
We reserve the right to slightly modify or change this product without notice.
GEARING:
Gearing (video tutorial to follow or call for explanation):
Use a 42T front Chain wheel to “Clam Shell the motor and bring the chain line inbound – we sell a cheap Lekkie clone version)
Reduce your rear cassette size to improve the chain line, removing any gears smaller than 15T and create your perfect centre-line around the 26T/28T rear sprocket (depending on wheel size)
Remove the old 9 -10=11 speed cassette and use the gear range from 15T to lowest gear. We love the Shimano XT CS-M771-10 speed cassette as shown in the photo. Use spacers to give you a perfect chain line for the gear of your choice. For 27.5 and 29er set ups we recommend a 28T rear gear. For 26″ wheels a 26″ T gear. For fat bikes as big as you can get! (32T +)
If you want to be very smart, you can use a 2.35 mm spacer from your old cassette to space out a 17T as a “Get you home” cog for pedalling or PAS assist in power level 1. But you might have to manually put the chain onto the cog. Use your old derailleur as a tensioner and give your self enough chain (we recommend KMC x10e chains) to move up and down you have. You will want to adjust your max/min screws so the chain does not slip off the outer sprockets (You may need to change these for longer screws)

Customer review:
Graham C I don’t think the BBSHD is weak as people say. Abuse it yes and something will fail just like any mechanical product. My motor was purchased from Francis Janssen in November 2017. Since then I have completed 7000 miles with approx half of those miles with a Luna Ludicrous controller fitted. My 20 miles daily commute, downhilling, bmx tracks, trails the lot ! I’ve not touched anything internally on the BBSHD and it’s running better than ever, all these stories of nylon gears failing I’m sure is down to the rider, have some mechanical sympathy and you’ll be fine. As Francis states I have now fitted the ASI 888 running on 72v, I followed his advice, got my chain line in order, correct gearing and 500 miles later she is absolutely flying, a weapon indeed. It’s far exceeded my expectations, high revving, smooth ramp up of power, throttle response, acceleration is crazy compared to the Ludicrous, top speed, all fantastic and so much fun, it does not feel like the motor is working hard. I am extremely pleased. I can thoroughly recommend this conversion and Electron Cycles ( Francis Janssen) for there professional services. Go for it !
