    My Bafang Ultra Mountain Bike! Frey AM1000

    Based on experience with the BBSxx, it wouldn't surprise me to learn that Bafang paired the same core motor hardware with a "1000 watt" controller or simply tested it at higher power, confirmed it could handle it, and changed its nominal power rating. I have a Luna BBSHD labeled 750 watts and a...

    My Bafang Ultra Mountain Bike! Frey AM1000

    Yes, you and me both. The G521.500 says it uses a mounting plate like this: The G510.500 is an older version, most likely replaced by the G521.500. It uses the same mounting as the 750 and 1000, so I don't think I can upgrade to the newer lighter 500 watt, but I could upgrade to the heavy...

    My Bafang Ultra Mountain Bike! Frey AM1000

    Sorry for the long post, just thought I'd share some photos... Not a great photo, but just for size comparison, the two Freys side by side: The only "modification" I've made so far was to move the gel saddle from the fat tire Frey to the white Frey to be comfortable on a ride I did on...

    My Bafang Ultra Mountain Bike! Frey AM1000

    For anyone interested in the Torque settings... Karl Gesslein made modifications, but only because he had a Ludicrous controller. This was specific to a Ludicrous controller to correct lurchy startup behavior. The ONLY numbers Karl modified from factory settings were MinCur%, MaxCur% and...

    My Bafang Ultra Mountain Bike! Frey AM1000

    Since Frey intends to begin ramping up production on the fat tire version of this bike, I'm wondering if there is any value in providing feedback on potential options to mitigate the so-called "self-steer" when riding on asphalt? I realize I'm not using the fat tires on the riding surface for...

    No label on the rims, but I measured as best I could without removing the tire and they appear to be 40mm width outer edge. -Sean SF Bay Area, California

    My Bafang Ultra Mountain Bike! Frey AM1000

    Here is a photo of the bearing screw from an AM1000 that was assembled by someone from Frey, so it appears you have assembled it correctly. In other words, if it is a flaw, it is a design flaw, not a build flaw. edit: oops, sorry, just saw your edit that you already figured out it was by...

    My Bafang Ultra Mountain Bike! Frey AM1000

    Good suggestion, I'll try to separate out my performance feedback between my thoughts on the Frey itself and my thoughts on riding a fat tire bike for the first time and what it feels like to have torque-sensing for the first time. The tires are CST BFT 27.5x3.0 - I think Cheng Shin Tire is the...

    My Bafang Ultra Mountain Bike! Frey AM1000

    Anyone in the San Francisco Bay Area who wants to test ride the AM1000 or the FAT1000, let me know and we can arrange a day and time. Also, I'd like to make a video walk around of both bikes, some side by side comparisons perhaps? Open to any suggestions, what is it people would like to see in...

    BBS01 speed showing 00.1mph at top speed

    it shows 00.0 at lower speeds, 00.1mph at top speed. I re-oriented the speed sensor with red LED pointing toward rear of bicycle. Now it is lit up all the time and blinks off when magnet passes, opposite of its behavior before which was only to blink on when magnet passed. Either way, speed...

    My Bafang Ultra Mountain Bike! Frey AM1000

    Hi! I want to give a big THANK YOU to Ivy Wang and the rest of the team from Frey who I met at Sea Otter Classic on Sunday. Ivy was very welcoming to all of the ideas I shared about customizing e-bikes. She definitely knows what she's talking about - at one point in our conversation, she...

    My Bafang Ultra Mountain Bike! Frey AM1000

    I originally just came here to ask Ivy from Frey why some of the Bafang Ultra motors have an orange "BAFANG" on the cover plate and some are just black and white. I've been trying to find a pattern and so far none. The photos on the Bafang website show black and white, the photos on Luna's...

    How To, 50A BBSHD Controller Mod

    " I got a bunch of 3 milliohm ones from Mouser that are the same physical size." For the Bafang Ultra, to swap out the 5mOhm and replace it with a 3mOhm, can you please tell me what is the part # from Mouser? Is it Mouser #: 660-PSIDTEB3L00F...

    Bafang HD cuts power and turns off

    I'm having this exact same issue, but trying a new display didn't solve it for me. Seems to occur especially at higher assist levels. Screen flickers then shuts off. Right before shut off, battery incorrectly shows super low voltage. I can turn it back on immediately, battery shows 41.8...
