Archon controller compatibility and efficiency questions. Since the Bafang Ultra/620 has been out for a while now, I understand there have been at least two factory controller updates/revisions having to do with the rotor shaft rotation position sensing system. The earliest version used a...

One fairly credible source is https://electrek.co/2020/06/23/sondors-rockstar-cruiser-lx-bafang-ultra-electric-bike/ Whatever your opinion of Sondors and his eponymous company and its peculiar history, there is no denying that he’s sold a lot of bikes. Thus he has economy of scale component...

Update During and after a 10 mile break-in ride, both the front and rear brakes with the changes described above have quieted down quite a bit with no more low frequency 20-100Hz judder. All that’s heard is the expected grinding/scraping brake noise with no odd harmonics. Feel remains good...

As per a previous post, they are a battery manufacturing company Frey outsourced at least some of their CC group order production to. Both battieries I ordered with my CC have TurnLife labels/serial numbers on their cases. They are a much bigger company than Frey itself. I take it your battery...

In a break from the 24/7 George Floyd coverage (I live in Minneapolis), I looked at my CC’s brakes in more detail. So far (a hundred miles or so), they work just fine with good power and modulation feel; they’re just annoyingly noisy especially in rolling to a stop, although recently the rear...

Slap Guard You can get the same guard shown in the Electrek video on the AM1000 They come in a few different colors (including red) with the video showing blue on a yellow frame. See...

Indeed what succeeds or fails with crowd/herd momentum internet marketing is quite strange, both in politics and the ebike biz. See: https://electrek.co/2020/05/23/the-story-lectric-ebikes-lectric-xp-founders/ for a success story about the latter. The keys for them according to the article...

Here is an interesting video by a Canadian ebike dealer who went to a big bike show last Fall (before COVID) and previewed and test rode some R & M bikes. See: At about 12:00 you can hear the juddering "drum roll" noise as he brakes to a stop just as described above which I would never...

Some observations on the Frey CC battery and some early range measurement results I ordered my CC with an extra battery. Both have a serial number spec manufacturer’s sticker label with serial numbers within 5 digits of each other, probably indicating that they’re from the same production run...

Here is another initial impressions report on the CC, which I would summarize as being enthusiastically positive just as the “Happy Days” fan here, but this time from a first time ebike owner. So I’m mostly going to ramble on my “ride experience” satisfaction without any preconceived notions...

Bolton apparently agrees with you on the "Fugliness" factor since he's nicknamed the hub and mid ultra drive models he's importing as Warthogs (reference to A10 low altitude attack bomber used in Desert Storm and not lion prey). See: Among the reasons Frey has the reputation it has in the...

You seem to have been born under a bad sign when it comes to the CC. Reminds me a bit of the old Li’l Abner comic strip character “Joe Btfsplk” with his constant attending dark cloud. But then you’re likely too young to get this reference. Percussing and stethoscoping (as your GP would...

Depending on how much more power you need for your Rover, Bolton sells an controller kit upgrade that apparently significantly alters the ride feel of the bike. There's a guy on Youtube named CitizenCycle who's done an independent review of the controller kit covering its install, performance...

Frey CC Range Primary State Variables Because of the rainy frost warning local weather, my CC maiden voyage was down in the basement underground parking concrete bunker where I live. Since this was my first electric bicycle I did several loops around just to get a feel for the machine as a...

Regarding #1 --- must be a common occurrence. My bike's kickstand mounting hardware had extra long bolts, washers, star locking washers, and finally jam nut nylon insert nuts for the other side. Only some peculiar resonance would cause all this to come loose. Then there's always loctite blue...

Simon: At around 7:05 in your video you say: "... under throttle it won't pull away from standstill to protect the drive train." or some very similar words. Was this how the controller firmware was setup when you rode the bike in China? Apparently the AM1000 and EX don't have this "safety...

Some educational sites, mostly about Bicycle Frames: The Zen of rear suspension design While I await the arrival of my Frey CC, with time on my hands, I thought I’d delve further into why I bought it in the first place. A big factor was its low step through full suspension design which didn’t...

Since this thread seems to be most recently about the Frey CC, this seems to be the best place to post this A possible reliable direct-from-China vendor besides Frey Under Covid19 lockdown in my senior community, awaiting the arrival of the Frey CC I ordered last December under the USA group...
