Hey guys, I'm new here. I have a pedelec with the Bafang Max torque sensing motor. Not sure whether it's 250 or 350w, but it's this one: (https://voltonbicycles.com/shop/alation-mid-drive-48v/) I've put about 500 miles on it so far.
I looked through the stickies and didn't see anything specifically about the issue I'm experiencing.
Power delivery is smooth and quiet and I have no issues when I'm pedaling. However, when I find myself coasting at medium to slow speeds - like when approaching a stop sign - I notice a repetitive noise that sounds and feels a bit like the motor is trying to get in gear and accelerate. Sort of like if you're standing on one pedal at nearly a standstill and the bike isn't quite sure whether to deliver power or go into neutral.
If I'm coasting at a high speed, like 25-26 mph going down a hill, it's not noticeable. Only when I'm going 10-18 mph or so in the middle gears (3-6 or so, it's an 8 speed with only one front chainring).
Should I be worried about this? My ride today was the fastest yet - I powered through almost 19 miles in 59 minutes with 1,000 feet of egain, but I noticed the noise a few times. I don't think it's the chain, derailleur, or cassette making the noise.
The only modifications I've made to the bike are adding a rack and unlocking the speed limit (now set to 60 km/h but realistically I can't go higher than 50 km/h without insane cadence) using the stock Bafang passcode. I have not reprogrammed anything.
Thanks in advance for any info!
