I've been using NixFrixShun Ultimate Chain Lube on my chain for a few years now and been pretty happy (not that that means anything since there are so many factors affecting chain longetivity). Lately I've noticed new spray-based products aimed at the bicycle market. What's interesting is...

The DJI is pretty impressive, from the 800wh battery in the downtube to the Action 4 touchscreen in the top tube. All controls completely wireless.

I bought a Grin Satiator years ago during a big sale. I'm just now starting to use it. I edited a pre-canned profile and now decided I want it back. I can manually restore the settings, but it's lost the precanned profile's name. Is there any way to perform a Factory Reset on it to remove all my...

The SRAM GX wireless derailleur is under $530 now at Amazon. The blurb claims: Is this really true? On my Ultra bike, I've got a Shift Sensor installed to pause the motor when shifting. Obviously, with wireless the Shift Sensor has no wire to connect to, so I won't have that. BUT, if it's...

SRAM 12 speed GX drivetrain (mountain). After several off-road rides, one of which included some pedal strikes, noticed my bike wasn't shifting well. The usual cable length tweaks didn't solve the problem. So, cleaned the bike, re-oiled the chain, and proceeded to setup the derailleur as if from...

This weekend some friends came over and we decided to go for a ride. Since they don't own eBikes, we stopped by our local Pedego dealer to rent a couple. Although they wanted a mountain bike layout, because they admitted we were staying on pavement, the dealer steered them from the Trail Tracker...

For the past few weeks I've been on a mission to finally get our Bafang Ultra motors (UART) tuned. I've learned a lot along the way, thanks to some posters here and to some reverse engineering. There have been several guides posted on the interwebs (old joke, sorry), which surprisingly have...

I was re-reading the available Bafang Ultra tuning guides/suggestions to see what they said about the Pedal Assist tab, which looks like this in the Windows Application: As I have posted before, most of these parameters seemed like they were left over from the legacy cadence-only-sensing...

If you're starting out to tune, or re-tune, your Bafang Ultra G620/M510 motor, you've come to the right place. There's a lot to setting up an Ultra to ride the way you want, but if you take it a step at a time it won't be as daunting. You don't have to do them all at once - I actually recommend...

This will be 2 Posts: One on the decoding procedure and results, and then a starter post on how to tune based on the revolutionary new discovery. I predict (and hope!) that this thread will get quite long as people re-evaluate their own tunings in light of the new information presented here, and...

While most of the discussion of Bafang Ultra motor's settings revolves around the somewhat cryptic Torque Tab, the Basic Tab, on which you set up your PAS level behavior, is the simplest yet most important tab to setup. I think every Ultra rider should setup the Basic Tab, as no OEM does it...

I'm doing another round of Bafang Ultra tuning, and the Torque Live Data page was helpful in setting my Base Voltage and Delta Voltage table values. But, I don't understand some additional information available on that page: Speed Signal Level? Speed Signal Acc? And finally, dos the Torque...

The speculation I put in this post for this thread turns out to be incorrect and so I've deleted its content, as well as my follow-on posts.

EDIT: This revised post corrects and updates previous information. Thanks to @ProphetZarquon for his insights! EDIT #2: See post #10 below for a How-To primer in case you don't want/need to understand but to try this out. Everyone should update their Base Voltage at least! I've undertaken yet...

I've decided to keep this for potential later use, as UART controllers seem to be in short supply.

I'm thinking about spending the money to get the fancy wireless Rockshox Reverb AXS dropper post. I'm not understanding Rockshox's sizing instructions, though. In particular, the "Minimum Exposed Seatpost" measurement. That's really the "Maximum Exposed Seatpost" measurement needed, right...

I've got two Apollos, which have been good bikes for us these past couple/few years. However, just recently, one of the bikes began having problems, which I eventually (as in too late) tracked down to the little black wire grommets that cover the holes in the carbon fiber frame through which...

Awhile back I upgraded the brakes on my wife's bike from SRAM's to Shimano M-8125s, which have Shimano's compound action lever and 4-piston design. Unfortunately, the brake lever has an attachment point that isn't at the end, but is in the middle, like this: It's kind of hard to see here, but...

As part of getting ready for the riding season, I've been going through the bikes making sure everything's setup right. You may have seen my threads on brakes (success!) and Bafang (Ultra) speed sensor (waiting for part to arrive). Now one of the bikes on a test ride is skipping with high power...
