Did you ever wish your BBS02 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?

This sine wave  controller has everything: super quiet, field weakening (allowing higher rpm), set maximum amps, set maximum watts, maintain these figures while volts drop, totally plug n play and potted to 100% waterproof (removing the loom form the controler will void any waterproofing warranty).

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  motor pull much harder and release around 15% more speed than a 52v 50A Bafang controller and whopping 100% more power than the standard and go 72v 200% !!!!!!!!!

These controller have been set up so that it can handle anything from 40A (90 A burst) up to 2600W (52V) or 3250 (72V) but for the BBS02 we have turned it down to 2600 watts (easily within their design). This might mean a little explaining:

We have tested the BBS02 to destruction and on more than one occasion right up to 4000 Watts and learned a few things, real facts and not the odd exception. We then applied the same science to its smaller brother the BBS02.

Amps create heat, heat weakens the nylon gear and too many watts snap the pinion, or can simply burn out the motor. 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 2000W but as you increase your volts (72V, we capped the watts to 2800W.

Power Settings

From customer feed back, we have tried to make the Pedal assist function more sympathetic to your drive train and more cycle usable. The Pedal and throttle now use the same power scale. Pas level is set at 9 by default and each level totally tunable by yo the customer. PAS level amount can be swapped to 3 or 5 through the display. This allows for a smoother take off and more refined pedal experience with each power increment more gradual. However, using the throttle will still give power levels of up to 2800w on the 72v system.

PAS function is available with a choice of up to 3 – 5 – 9 levels via the display. Now with tunable PAS through our new Electron display – (Email request required after purchase)

GEARING:

Use a 42T front Chain wheel to “Clam Shell the motor and bring the chain line inbound – we sell a cheap Lekkie clone version with zero quibble 1 year warranty (please ensure you buy the BBS02 version as the HD version is not compatable)

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)

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

Photos of rear gears and spacers are not included

Customer review:

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 800 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 !
