CYC X1 Pro Gen 2, ASI BAC 855 Controller, Mid drive Motor 52V Torque Sensing up to 65A 4000W continuous, Burst 90A 6400W
This is the very latest edition with Torque Sensing, Where the amount of pressure on the pedal dictates the amount of power to be used by the motor. Give your legs the power of an android! The system directly feels how much effort you put through the pedals and adjusts the power accordingly, to give you that bionic man but natural feel like you you are a part of the bike and not just spinning the pedals.
When comparing prices, remember shipping costs, tax if you’re in the UK, cost is included free delivery with TNT and delivery within 3 working days.
Motors like the CYC x1 pro can kill almost anything battery wise, if ridden incorrectly, but if ridden correctly, will give very reliable use. Just like a car or motorbike, full power continuously will speed up breaking things. When riding your bike, allow the motor to spin when in high power mode. Use your low gear (big teeth count on the rear) this will take the load off the motor. This will also give you better range and stop everything from over heating. A battery designed to handle 65 A and higher bursts, can still be damaged by ridding at long intervals of full power and doing so increases the chance of failure. When you want to ride very fast on throttle, set you gear to allow the motor to spin in the middle to top of cassette, to save your chain and the reduce the load to the motor. When you want to PAS (pedal), drop the power and use the whole cassette. Your bike wasn’t designed to do both at the same power setting. Riding with electrical sympathy, is better for you, better for your bike and better of your electrical components.

52v (14S 4P) Sony VTC6 12Ah, 624Wh, 65A discharge down tube battery with 3A charger
This has been specially designed to get the best balance of performance and range in a down tube battery yet monstrous 65A – discharge
Maximum watt draw continuous 4300 watts
This 52v 12Ah (fully charged 58v) has significantly more power than any other battery 52V battery and with 65A on tap, massively increase acceleration. With 624Wh riding in the lower PAS range will still give massive range.
We wanted to provide a battery that allows balance for a bike and give as many amps possible fo rthis CYC controller version CYC X1 Pro motor. Yet with a maximum cell amount of 70 cell in a case, we opted for 14S4P (56cells) and the very expensive and hugely reliable Sony VTC6 to deliver. and used the extra space to use a large 80 A heavy duty BMS
This is the very best of battery technology with 3A UK charger. 80 Amp Nominal BMS welded to pure nickle. This is the highest UK output available down tube type battery on the market, designed to fit on down tube utilizing water bottle bolts. These are 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 56 cells that retail in the UK for around £5 each! not including: BMS, casing , charger, shipping taxes AND FABRICATION.
This in reality a small battery for such high power 20S4P. Motors like the CYC x1 pro can kill almost anything if ridden incorrectly. Just like a car or motorbike, full power continuously will speed up breaking things. When riding your bike, allow the motor to spin when in high power mode. Use your low gear (big teeth count on the rear) this will take the load off the motor. This will also give you better range and stop everything from over heating. This battery is designed to handle 65A and higher bursts, but doing so increases the chance of failure. When you want to ride very fast on throttle, set you gear to allow gear and middle to top of cassette to save your chain and let the motor spin. When you want to PAS (pedal), drop the power and use the whole cassette. Your bike wasn’t designed to do both at the same power setting. Riding with electrical sympathy, better for you, better for your bike and better of your electrical components.
Because this is such a powerful battery and way beyond the realms of normal, we have had to make some modification. The power cables exit through the rear of the battery and not through the cradle. No cradle in the world can handle this amount of power. The cradle is still used to mount the battery and locks as normal.
Mounting your Battery
The batteries still mount as usual on the at the water bottle bolts and can be easily detached. However, because of the massive discharge amps, the battery cables exit direct out of the battery case (at rear) and not through the cradle. This means that it will be necessary to unplug the XT90 plug when detaching battery.
The battery can also be balance charged through the xt 90 discharge port although there is a dedicated 2.1mm jack port.
We recommend the addition of a velcro strap 400mm x 30mm Afatex by Velcro (easily found on Ebay/Amazon)
We do not recommend these batteries for power output above 65A, these will handle all 65A or lower where a controller has a 48-90V applications but have been specifically built for the Bafang BBSHD ASI BAC uparade and CYC X1 Pro. They have XT90 connectors and are “plug and Play”
Like any device, running it constantly at maximum could lead to failure. Dont ride open throttle non stop!!
Please ALSO note, these are genuine new cells and made up into complete battery hand made here in the UK. Due to Paypal fees, 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.

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.
* 6 Month Warranty is for manufacturing defaults and does not over miss use or accidental damage. These units are extremely strong and robust and will not let you down unless abused. We undertake warranties here in the UK. We take the pain!
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.
International orders: We can send batteries to the EU only buy ground freight and UPS. This is expensive and individual shipping quotes will be necessary. Please send us an email with your address for an estimate – thank you
