Ultimate BBSHD, battery and Controller Screen –complete kit with Electron PAS Tunable Display, 52v High performance 17.5Ah battery and 4A charger and Gear Sensor motor cover all included!!
This version is designed for increased speed and blistering acceleration with great pedal function Now with tunable PAS through our new Electron display – (Email request required after purchase). This allows 9 increments of pedal assist from 150w- 2200w.
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 52 V motor pull much harder and release around 20% more speed than a 28A Bafang controller
These controller have been set up so that the motor can handle anything from 50 A up to 32500 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 2200w for this battery combo. but now add 10 – 20% improvement through field weakening and more accurate phase injection.
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 38 – 45 MPH, depending on how you gear your bike. You can accelerate faster or have a higher top speed. We find 38+ 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. This may take splitting the cassette up and using spacers to put the optimum gear in the center for better chain line, place and the smaller low power gears on the outside. Then the none used gears then go on the inside where they are used just 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 may be able to go something like 20T rear cog.
We have tested this set up thoroughly with a 250 lb rider without
We ship the controller with three power levels, but can easily be change through the display to have either 5 or 9 levels. 9levels is recommended for you that like to pedal but try and use the lower levels of power if pedalling and get that perfect big cog for full power throttle use.
level 1 is around 1000w and hits speeds of around 30 mph with modest acceleration (similar to a standard BBSHD) and a range of around 30 miles
Tunable PAS through our new Electron display – (Email request required after purchase). Rock Solid reliable with no updates required and no leaky case.
Full PAS function is available with a choice of up to 3 = 5 – 9 levels.
ONLY OUR Tunable Electron display will work for PAS without additional firmware.

Additional mounting kit (not included) here:
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 pedaling 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)

52v 17.5Ah Smaller Cased, Semi High Power Long Range
50A/2100W Down Tube + 4A Charger
More powerful than our nearest 52v 19.5Ah (more amps). More range thnan our 52v 16Ah. This is managed by a 50A BMS and 5 parallel cells all handling 10A each 18650 cells. LG MJ1.
The LG MJ1 are extremely similar cells 3500Mah per cell and with 4Ah UK charger. 50Amp Nominal BMS. 5p x 10A cells and designed for 2100w max motors (will burst higher and pure nickle welded contacts). Downtube type battery, designed to fit on down tube utilizing water bottle bolts. This battery is physically the smallest we do yet still have enough power for the BBSHD and CYC Stealth motors. These cells are volumetrically small than the 21700 yet more powerful (we can squeeze more cells in).
We do not recommend these batteries for power output above 50A (22000watts), these will handle all 50A or lower 48/52V applications but have been specifically built for the Bafang BBSHD and G510 Ultra drive and CYC Stealth. They have Anderson connectors and are “plug and Play” for Bafang BBS02/BBSHD motors.
Please ALSO note, these are genuine new cells and made up into complete battery specially to order for us at the factory. These are not “off your shelf” batteries that are found similar to by other vendors. We buy the same cases and there it stops – everything is bespoke to Electron Cycles Limited. We simply can’t buy a single battery, We have to agree to a production run of at least 30 batteries. Thanks to Paypal fees, shipping and taxes the markup is minimal! Not all down tubes are the same and some slight modification maybe necessary to the mounting plate of the battery. You tube has an abundance of “How To” videos.
We do not connect the USB port as we have found that with our wet UK weather, can cause reliability issues.
We recommend the purchase of Alfatex velcro 30cm * 3cm (available on Ebay) for additional support.

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 preset level and turn on again when this level drops.
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.

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 !
