Bafang feeble walk mode. Fix??
Bafang feeble walk mode. Fix??
My Bafang mid drive has a walk mode but it is so feeble that it is pretty worthless. Much slower than walking, and no umph for an incline, let alone a long steep hill.
Anyone know if there is a software fix for this and where I can be done?

Re: Bafang feeble walk mode. Fix??
i had an issue with my tongsheng mid drive recently. It sounded like a mechanical failure internal to the motor. Turned out to be a software problem with the battery management system which required a reset. This involved charging the battery at the ouptput teminals before reverting to normal charging.
Of course your problem may be different but worth trying this first.

Re: Bafang feeble walk mode. Fix??
I suspect it is a software issue.
It may not be a fault as such because the bike is exceptionally heavy. [Fat cargo bike].
I think it needs reprogramming to give a bit more umph but I have no idea if this is possible or where/who could do it.

Re: Bafang feeble walk mode. Fix??
I have the same problem with my Bafang. I don't think it's a fault though. It's to assist when walking along with your bike.
The problem I had was getting my 30kg bike up the 20 or so steps to my front door.
My solution was to tweak the software. You'll need a usb cable https://www.amazon.co.uk/Bafang-Program ... HJ1ZQ&th=1 (there are cheaper ones available) and the bafang software. There are numerous places online to download this but it's like hunting for a pink elephant in my experience. There is an easier way which is to hook up your motor to an android phone (with said cable)and use the Speed app available on the Google app store .I don't know if it's available for iphones.
You can basically alter one of the 9 PAS settings to run at a much lower speed and power. I have mine set to 50% power and 45% speed. Using the throttle and my lowest gear (40t chainring 36t cassette) it'll roll up any incline with full panniers at around 3.5 mph. I have my throttle right next to my left brake lever.

Re: Bafang feeble walk mode. Fix??
That's interesting, but you are using the throttle.
My walk mode uses a long push on the PAS controller ( the minus button) then it is hands free. This is helpful off road as I can wrestle with the bike using both hands .

Hmm, when I take my finger off the minus button walk mode ceases straight away.

My Tongsheng walk mode drives through the gears....so the higher the gear, the quicker I walk!

Re: Bafang feeble walk mode. Fix??
Have you tried riding it in walk mode. No pedalling required.

Re: Bafang feeble walk mode. Fix??
No, I didn't try that....but I imagine I will!

Re: Bafang feeble walk mode. Fix??
Sounds like you may be using walk mode whilst sitting on the bike, rather than walking beside it. That may explain why you find it rather feeble!
