No idea to be honest. My bbs02 shuts down when the battery hits 41v. Minor hills can be done with 42v and 43 will climb slightly steep. 44v is my cue to recharge the battery. Obviously, these numbers vary wildly depending on the hill, wind speed, tyre pressure, human effort and pas used. This is...

I'd suggest getting your display to show volts instead of percent re battery range. Far more accurate. I tested this myself. My battery shows 54v on a full charge. If I do 20 miles it'll show 2 or 3 volts less than when I started but if I had percentage showing on the display, the battery will...

Other than reasons I've stated earlier, what possible reason would you have to pedal and brake at the same time? Even in that case, the motor would only be under the same strain as it would under a steep hill climb...depending on how hard you're pedalling obviously. Throttle shortages etc can be...

Nonsense.

I disconnected then chopped the brake sensor cables so there weren't any dangly wires flapping about. I've tweaked the motors settings so it stops running the second I stop pedalling. I find that in some circumstances, I can use the motor on rocky uphills yet still use the brake to control the...

That's does actually make more sense...carry on

It was indeed a rubber mallet that I used as it kept coming loose. I have the motor limited to 500 watts which it almost never reaches. The bearings that went are the ones you see at the bottom of the table. There's one set just behind the main drive cog and another next to the locking ring...

You wanna be careful with tightening that nut. I recently had to rebuild my BBS02 because the bearings had been obliterated due to overtightening. Not something I'd wanna do again.

I'd advise checking what type bottom bracket you have. Mid drive units such as the one you want are built for use with an older style square taper bottom bracket. I suspect the bike you are wanting to use has a hollowtech bottom bracket and therefor will need an adapter which I recently...

Help! My old bike with a bbso2 was killed in an accident and I'm wanting to transfer the motor to my new bike...however...the new bike has an MT500 pressfit 92 bottom bracket. I believe this to be of hollowtech 2 heritage. The old bike was square taper. Can I get advise on exactly what sort of...

Time for an update me thinks. Thanks for all the help so far. I've taken a somewhat different route though. I've a BBSO2B 48v 750w motor and 20ah battery arriving tomorrow. That'll give my bike a bit more muscle and if I understand correctly, give me a bit more mileage between charges too...

The pedal speed limit I've just reset to 40kmh. Probly pressed it by accident to display speed limit.

700 X 42c. I've set the keep current to 100% but I think I've adjusted something else too. Out with the doggy tonight and the bike was sluggish as anything. I'll look tomorrow. I'm knackered.

No it was perfectly silent. No cutouts. I just know I was having to pedal like a madman to keep moving. The only info I have on the battery is the advertised lingo from when I bought it. Hailong G70 36v 20ah with a 35amp fuse. I've read that the standard BBSO1B 250w can't handle more than 20amps...

No idea about voltage sag. If memory serves, the display showed it dropping to around 34v and it had already done a good 15 miles of hilly rocky rough trail. Same thing?

You must be alot stronger than me then. Battery is 20ah. The bike and I weigh maybe 90kg. Luggage was I'd guess around 40 or 50kg. Gearing is 40t front and 36t rear. Much lower than yours. I got to the top of that climb and couldn't catch my breath for a good 5 minutes.

I have indeed. It's currently running at 18 amps but I darent go any higher incase I fry it. I'm not long back from a failed tour in Wales and the motor struggled heavily loaded up a 20% climb. I was hoping a bit more torque can help there.

Is this correct? Does such a thing exist? Bafang Mid Drive Controller BBS01B BBS02B BBSHD 36V 250W 350W 500W/48V 500W 750W/52V 1000W Latest Model https://amzn.eu/d/aseRsky I'm currently running the 250w 36v legal version and wondered if this thing can be just bolted on. If so, would it have a...

Locked out? As in the 15mph limit? Mine was limited by software. A specialised USB cable and an app/program allowed me to adjust the max speed to 40kph (whatever that is in mph). That max can be set within the motor itself or by the display on your handlebar. Using the display you could tweak...
