Will a new controller bypass preset speed and PAS settings?

[BrianK]

I have a 2018 Rambo r750g3 (hunting e bike) with a BBS02. The bike came with top speed set at 18 and PAS set as 1-5.

I’ve used the Bafang passcode (0512) to enter the advanced parameters settings, and changed max speed to 30 and PAS to 1-9 several times now.

However, each time it reverts to the original speed and PAS settings.

Is there a way to jailbreak these settings?

Would installing a new controller bypass these settings?

You may want to try a programming cable first.
I know my top speed changes would have no affect until I changed it using the cable.
When reading my stock parameters with the programming app, Top Speed was set to a static 40kmph and I changed it to By Displays Command.

E-Bike Conversion – Software

It’s been a while since I wrote the posts about my electric bicycle conversion project. The bicycle runs fine so far and I finally finished rewriting the software that configures its controll…

. In my experience the BBS02B isn’t the best choice for hunting fat bikes. There’s not much more to squeeze out for speed on a hunting bike with a BBS02.

Thanks Thomas. I upgraded the front sprocket to 46t (from 34t) to make it road friendly. I might upgrade to 52 t.

Eventually I’ll upgrade it to BBSHD but for now I’m just using it for low speed road riding so it’s more than sufficient.

I found a local guy who builds BBS** bikes from scratch. He already has the cable and all the LunaCycle tuning settings so he’s going to upgrade it for me.

I don’t mind getting the cable but I only have an Apple MacBook and the Bafang software requires Windows as far as I know.

Careful moving up to larger chain wheels and trying to squeeze more out of the BBS02. Climbing and offroad with 46T-52T will add some stress and make overheating a strong possibility.

Fortunately my “off road” is limited to fairly flat rails to trails, and my local riding has no really long hills.

I’m really only using PAS 1 & 2, with occasional bumps up the PAS 3 for these local hills.

If I do burn up the BBS02, Luna sells the bare base BBSHD motor alone for $499, for a direct swap using my existing wiring harnesses.

I'm using 46 teeth with my BBS02B and do the same type of riding as you are now. I have taken the bike on a few shopping trips to home depot and harbor freight that required me to traverse some steep long hills and I had no problem doing so... I did stay in the lower half of my 7 speed and did pedal as well in PAS 2 - 4. I did not sustain above 7 amp and when I arrived at my location the motor was at ambient temperature by feel

I'll add that my bike with the motor/battery weighs in at about 62 pounds and I'm about 160lb on a good week

Obviously, you are one that understands the BBS02 limitations. BTW I still ride a 2014 BBS01. thousands of trouble free miles. When it does fail there are NO parts.

Honestly I don't feel that it has any "limitations" It's an eBike Conversion for a "bicycle" and my definition of that is that it should be ridden as a bicycle with motor assistance. If you want to be propelled at top speeds with massive amounts of torque, buy a motorcycle.

I have a people hauler and a sports car... I don't see any limitations there when used as intended either...

I'm not certain as I haven't tried Luna's settings but from what I've read they seem to be geared towards the aggressive and/or trail rider. Please correct me if I'm mistaken.
But I actually tuned my settings in the opposite direction by lowering some current settings and increasing ramp up time. I no longer have aggressive lurching forward when going up the PAS scale or if I coast a bit and resume pedaling. My throttle is more of a linear ramp up and I added what I feel are lacking safety features by making PAS 1 the equivalent of what PAS 0 is on the stock settings so there is no motor activation at power up. I then made PAS 0 a throttle only setting.
For an old man looking for some exercise and to extend rides when tired or achy.. I've found the tweaks down suit my riding style much better than the stock settings.

You can easily add windows to your MAC using MAC BootCamp- should be on your computer already. I have been using Windows 10 on my MAC with no issues at all. Very handy for those times what you want to do requires Windows.
