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 52 V motor pull much harder and release around 15% more speed than a 50A Bafang controller and whopping 100% more power than the standard, while still using your standard display! (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.

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 3000W. A ludicrous controller at 50A has 2500Watts – so does ours, but now add 10 -15% improvement through field weakening!

Because of the weakness of the Nylon gear, the use of low gears is necessary when using throttle but as the PAS  Electron tuneable PAS display (Email request required after purchase) give a sublime full cassette pedalling experience. We recommend for full throttle: front 42T and rear no smaller that 28T on 29er or 27.5″ wheels and 26T on 26″ wheels.

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 to 2800w.

You no longer need other gears! your weedy legs are obsolete!!

Power Settings

PAS function is available with a choice of up to 3 – 5 – 9 levels via the display Electron tuneable PAS display (Email request required after purchase). Rock Solid reliable with no updates required or leaky case.

ONLY OUR Electron tuneable PAS display or our 750c display will work for PAS without additional firmware.

Please note that the Bafang speed sensor was not designed for this unit and can become inconsistent with higher speeds

Please note our controllers are locked and will stay locked to protect the hours and  hours we spent programming and developing them. Sorry no exceptions.

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)

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. Throttle only use in PAS mode “0” is available allowing to rest without pedalling and a further 9 levels available with “on the fly” switching.

These motors are regarded as the very best in the ebike world. Extremely quiet and robust. Fully Water resistant and internally lubricated within sealed casings. There have been recorded distances of 25000 miles and still going!

This motor is designed to fit bikes with a Bottom Bracket between 68 mm to 73 mm

The motor is designed to work with batteries rated at 48

Motor weight: 5.8kg.

Attempting to reprogram the controller may cause damage and invalidate any warranty to the controller.

* Warranty, 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 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. Controllers are not covered by warranty after 14 days.
Using high PAS in a high gear under heavy load may cause the controller to overheat (power level 9 in a small rear cog). Gears should be used going uphill or any other heavy load.
Attempting to reprogram the controller may cause damage.
Warranties are not transferable.
