Bafang BBSHD 1600 Watts (Peak) 850c Display+ 52V 21Ah Battery 4A Charger, Long Range Kit UK Stock
UK shipping included – Sorry No International shipping
BBSHD Mid Drive kit is light but strong and unprecedented levels of engineering (Rated 1000W – 1600W dependent on setting and have a proven to work reliably at 2800Watts) 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. 9 power levels available with “on the fly” switching.
These motors are regarded as the very best in the EBike world. Extremely quiet and robust. Water resistant and internally lubricated within sealed casings. There have been recorded distances of 25000 miles and still going!
The motor with the correct battery is capable of speeds over 30 MPH, however riding the bike correctly will ensure longevity.
Please take note of the following tips. An electric motor likes to spin fast. it means it is not labouring and not wasting energy and converting it to heat (wasted power). Your human legs can only spin so fast. So, in the lower power modes 1-5, you can use all the gears and the motor makes good use of the power supplied combined with your legs. But after power level 5, your legs really can’t keep up and you can feel that you’re not pushing much through the pedals and not really helping. At this point, help the motor by selecting a “lower gear” at the rear (bigger cog). The motor will spin faster, use less power, go further than a smaller “higher geared” rear cog. Sometime more is less. To test the theory, find a straight piece of track. Have a go at full power in your smallest gear. The bike will accelerate sluggishly and slowly creep to a top speed and be in the red full power zone all the time. Not try the same again in a middle rear cog. The bike will accelerate faster and hit a top speed quicker, use less power and most likely go faster!
This motor is designed to fit bikes with a Bottom Bracket between 68 mm to 73 mm
Please note that 1600 watts is only achievable with a 52v Battery.
Motor weight: 5.8kg.

Shark Electric Bike 52v 21 Ah
High Power Panasonic Battery & 4A Charger. UK Stock
This is the very best of battery technology: 14S6P 52v 21Ah (We will use either Samsung 35E or LG MJ1 depending availability, but will never mix these cells. 3500 mAh per cell and) with 4A UK charger. 50Amp Nominal BMS and double welded contacts). Designed to fit on down tube utilising water bottle bolts. These are specifically designed for high output discharge and sustained high drain of 50A. 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 £5.50 each! not including: BMS, casing , charger, shipping taxes AND FABRICATION.
These batteries have been designed for the Bafang BBSHD and other electric bike motors that have a rated up to 50Amp or up to 2200 watt motor. These will handle all 50A or lower 48/52V applications but have been specifically built for the Bafang BBSHD. They will burst much higher but we do not recommend running these constantly at high (50A)
Please ALSO note, these are genuine new cells and made up into complete battery specially to order for me at the factory. We simply can’t buy a single battery, I have to agree to a production run of at least 30 batteries. Thanks 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.
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.

Tips on riding:
The motor is not human and makes your bike a hybrid.
Motors like to spin fast, and thus use less power, not over heat and most of all use less electricity!
Using a 9 speed bike for example:
The whole range of gears can be used with your legs only – no surprise!
or with the lower PAS settings of 1-5
If you want maximum range use very low PAS 1-5 and any gear you want to let your legs assist.
Do not use the small rear cogs (10T-14T) in high power modes. High PAS in small rear cogs will kill your range! (your legs are not assisting).
Generally speaking, your cadence is much lower than the BBSHD’s possible 160 rpm. If you ghost pedaling at 30 mph in the 11T rear cog you are doing nothing to help the motor, BUT the motor pas switch is telling the motor that you actually want to go to its maximum theoretical speed in that gear which could be around an impossible 50 mph when it cant, because of resistance (tyres, road surface , Air etc) – you can use a cadence calculator online to check the speed with your gearing. When the motor can not achieve its ideal speed in a high PAS setting, it dumps loads of “Phase Amps” amps that are wasted producing heat as they cant be turned into motion and make the motor turn faster, they have saturated the motor.
As a test, ride you bike flat out without the motor and see what your top speed is . This maximum speed will be the speed that you no longer assist the motor. So if you go faster, dont fool yourself, stop pedaling and use the throttle and see if the motor is laboring or not. If you want to sustain this speed. Use the gear that lets motor spin fast but maintain the speed (not labor).
This is a general ism, as some very fit riders can achieve higher speeds in higher pas without over heating as they have a much higher spin rate, are lighter and powerful enough to push big gears ( do these people really need an ebike?)
Now using throttle only, find your top speed using the gears. You will notice the smallest or highest gear does not give the top speed, but it will use the most amount of electricity. Go down a couple of gears (bigger rear cog) and the speed will not significantly drop, but your power consumption will – gives you more range!
So for range use the small PAS and any gear you like as your legs are helping and the motor is not trying to achieve to unobtainable top speed.
For top speed use the throttle only and use the best gear, not necessarily the smallest rear cogs.
I use a 42T front. I PAS only in level 2, but throttle for top speed with a 16T or 15T rear cog ( i check my speed against power consumption).
If I am really lazy, I leave it in 16T rear cog (its flat where I live), use PAS 2 to get to 10 mph (helps the motor ) then use throttle only to 30+mph. This saves the motor, saves the drive train and im lazy. If I want to go miles, I use all my gears and PAS 2 only and the throttle up a hill in a big rear gear with it spinning freely.
At 30 mph throttle only I get 15 miles (I weigh 20 stone).
In PAS 2 I got fed up testing at 40 miles.
* 12 Month Warranty (battery) is for manufacturing defaults and does not cover 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!
* Warranty, due to the nature of use of these devices (Bafang motor and periphrerals excluding motor controler) warranty is limited to 12 months from date of purchase. Any damage as the result of water ingress, alteration to the wireing, may void warranty. This includes shortening of cables and changing connectors. It is the owners responsibility to proof against water ingress and avoid use in unacceptable very wet conditions, or useof direct water from hose/washers. Any alteration modification to controller or its subsequent wiring, even cutting the power leads to make shorter will immediately invalidate any warranty. Even when a batteryis disconnected, the controller can still maintains current and can 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. Damage sustained through water ingress is not covered under warranty.
Unfortunately due to the nature of controllers and their use, they are open to accidental misuse: getting hot from misuse of gearing (using high gearing/small rear cogs) and high power PAS settings, We can not warranty these controllers for more than 14 days from purchase. This is similar to the warranty on a car vehicle clutch. Attempting to reprogram the controller may cause damage.
Warranties are not transferable.
We reserve the right to slightly modify or change this product without notice.
