    Ultra Chainring Swap?

    Surprised.. Anna is typically pretty thorough. I had an error in my last order and she caught and corrected it while confirming with me. I paid for slow boat shipping and it went out next day and arrived in less than 30 days. Go figure.

    Ultra Chainring Swap?

    Did you ever receive anything from GBK? I just found this in the most recent Bafang catalog.

    Zen Photon Ultra - limited version (Bafang Ultra, Rohloff Speed hub, Gates belt drive)

    The Ultra is the common name for the G510 motor. M620 I believe refers to the complete system. Motor, display and battery Since M620 the motor system is printed on the motor face, many assume it's the motor model. But if you look at the serial number area the Mid Motor model is G510

    500C Display - Battery Meter never changes?

    As per my previous post it's probably more of a Bafang motor controller (firmware) issue. I know there are different firmware floating around but I didn't hear of any that addressed this problem. I never bothered to mess with firmware and prefer a voltage reading anywhoot. Curious... is your...

    Took a tumble

    I knew I had seen Stefan elsewhere!

    Oops,..

    Just checked my e8 chain. Double official KMC Headquarters issue. Ridiculously hard to use... Though no tools were harmed in the process. Again thousands of miles on the much more user friendly knockoffs and that's what's on my bike now and have been for a while. I did purchase a Shimano 10s...

    Yeah PC... You gotta get your missing links from Headquarters!

    Took a tumble

    So see knowing something and being able to implement it without purposely training isn't much help. Allowing hundreds of accidents to occur isn't something I would recommend to anyone other than Stefan 😜 I can't tell you how many drops I avoided by putting a leg down and pivoting back to balance...

    Took a tumble

    Depends on the speed and terrain but tuck and roll can be a better choice... don't try to break your fall with your hands or face.

    Took a tumble

    Yes and no... Sometimes you put yourself in precarious situations and full well know that a crash is possible. A true accident you don't see coming and is harder to defend. That said... Hundreds of accidents and you are definitely doing something wrong or just oblivious. All accidents are...

    500C Display - Battery Meter never changes?

    In my conversation with APT the manufacture of the 500c and the 860c that I'm fond of... The information is coming from the controller and the display is just that, only a display. So Ananda may be doing a better job with the controller and 3rd party batteries since they don't manufacture...

    But still hasn't learned how to avoid them.. Got it.

    Confused Between Electric Bike & Electric Scooter?

    I'm thinking scooter. Much easier to to handle/store and no wrinklling of clothes or getting your olives basted.

    Took a tumble

    Since I ride pretty aggressively and have had very few accidents, especially those I didn't see coming ... I wonder if it's a good idea to take the advice of someone who has crashed hundreds of times 🤔

    Why Charge to 80% and the use of smart BMS in Zen 52V,20Ah UL-2271 battery

    But for clarity.. The full 100% charge doesn't change the battery's capacity, its to keep the percentage fuel gauge accurate on the display... Correct? I've always read the calibration instructions reversly. You drain the battery down near cut off and then fully charge to mark the low and high...

    Oops,..

    Might be something to do with the KMC 6,7,8 sp quick link... The one that came with my KMC e8 chain was ridiculously hard to close.

    Oops,..

    I've yet to have one fail and my bikes are 750w and 1000w mid drives. They outlast the chain. But like you said I do carry a pair of spares in my tool bag just in case. Can't go through all that to wax a chain. I use Boeshield T9 which is basically wax in a solvent. After applying you let it...

    Oops,..

    The KMC ones can be very tough, especially on first use so I tried some knockoffs and haven't had any issues in many thousands of miles. Risk Quick Link Mucho easier and take the amount of force one would expect. So cheap... no reason to reuse.

    Why Charge to 80% and the use of smart BMS in Zen 52V,20Ah UL-2271 battery

    My Samsung tablet. They've had this feature for years. I've been following this advice from Battery University and set my version of the DIY Smart Charger to optimal charge voltage (51V for a 48V battery) by default In terms of longevity, the optimal charge voltage is 3.92V/cell. Battery...

    500C Display - Battery Meter never changes?

    Well you're a unicorn. When you say it works... Is it that it does eventually show a lower percentage? This is the first I'm hearing that anyone finds them accurate or useful. There is no calibration for them other than setting the correct nominal voltage.
