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 and co developer for this exceptional device.
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 52V motor pull much harder and release around 20% more speed than a 50A Bafang controller and exihilartaing 2100w. 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 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 2100w Electron tunable PAS display, 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+ MPH, depending on how you gear your bike. You can accelerate faster or have a higher top speed. We find 40+ MPH is enough. Bigger explanation further down.
You can still use your favourite 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 myt 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.
Electron Cycles Display switchable, display. Rock Solid reliable with no updates required and no leaky case, Now with user changeble PAS levels.
Full PAS function is available with a choice of up to 3 = 5 – 9 levels.
ONLY OUR Electron display will work for PAS without additional firmware.

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)
Photos of rear gears and spacers are not included
BBSHD Motor (standard):
BBSHD Mid Drive kit is light but strong and unprecedented levels of engineering (Rated 1000W – 1500W dependent on setting and have a proven to work reliably at 4000Watts) and Max Torque 160 NM) More efficient than HUB motors giving greater distance and response. This mid drive provides powerful ebike performance meanwhile keeps the original pedalling in comfort. With an integrated speed sensor, this mid-drive motor is compatible with standard bikes.

Shark Electric Bike 52v 21 Ah High Power Samsung 35E Battery & 4A Charger. UK Stock
Super powerful 14S6P 52v 21Ah Samsung 35E (high 3500 mAh per cell and) with 4Ah UK charger. 50Amp Nominal BMS and double welded contacts). This is the highest Amp hours UK available downtube type battery on the market, designed to fit on down tube utilizing water bottle bolts. These are Branded specifically designed for high output discharge and sustained high drain. Other inferior cells used in cheaper packs simply can’t deliver like these. If you think the cost is high, these batteries have 84 cells that retail in the UK for around £5 each! not including: BMS, casing , charger, shipping taxes AND FABRICATION.
We do not recommend these batteries for power output above 50A (2300watts), these will handle all 6A or lower 48/52V applications but have been specifically built for the Bafang BBSHD and CYC X1 Pro and G510 Ultra drive. They have XT60 connectors and are “plug and Play” for ASI controllers. These will power a cyc x1 motor motor but power must be capped at 2300 watts..
Please ALSO note, these are genuine new cells and made up into complete battery specially to order for us at the factory or here in the UK by our dedicated battery builder. 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. (Due to changing world shipping, we are now also making batteries here in the UK
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 (avaialabe on Ebay) for additional support.
Space required, please see photo= H 141 mm * L 368 mm * W 90 mm please allow another 25mm to get on and off cradle

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.
