About 15 months ago, I installed a Bafang BBS02B on a Bacchetta Corsa recumbent bicycle (see photos). All went very well, great installation, smooth ride, et al, 'till about a week ago when going up a slight grade I noticed a momentary power loss/hesitation. While in power assist with pedals, I could feel bucking, surging, and power lags in my feet. I said, "Oh Oh!" As my ride continued, I could feel these sensations even more. The power output no longer matches what it did with settings at 0 - 6. Eventually, about 15 miles from my return destination, the mid-drive conked out completely, and I was left having to power up hills and over dales using only my legs. I am 82 and the others I was riding with were getting paperwork together in case I died or something. The first thing I thought of was an electrical failure somewhere in the mid-drive assembly. Then whilst reading here and other places, controller failure sounded like a possibility. At any rate, I would surely appreciate any advice I can get from you good folks out there. Thank you so much in advance. PS, I did check power from the battery. No problem there.
