Yeah, running the software on my Mac also has issues. You can't be using the dark theme in MacOS, for instance, but at least it scales OK with the screen resolution. First thing to do, however, is read from your Satiator and save to a file in case you ever want to reset to factory defaults.

I previously worked at a off-road vehicle manufacturer. On the assembly line, they not only used torque wrenches, they used digital torque wrenches. They not only used digital torque wrenches, they used connected digital torque wrenches, and the torque applied to each bolt is stored in a...

I do NOT recommend using two actual magnets. If you have an EggRider or some other display that can set a large wheel diameter, then you can fake out the Ultra to thinking it had two magnets, but actually has only one. That doubles the speeds the SPD table uses, which can be advantageous for on...

Don't know what kind of charger you have, but I've done several profiles on my Grin Satiator charger: For my 52 volt (nominal) batteries that are large (over 1,000 wh): Choice of current: 1, 2.5, or 5 amps Full Voltage: 55.4v, 57.1, 58.4, and 58.8v (for 80%, 90%, 97.5%, and 100%) I rarely go to...

The first post in this thread has this table: SpdXX In KPH Out KPH Spd0 0.01 4.5 Spd20 2 8.5 Spd40 6 13.5 Spd60 10 18 Spd80 16 25 Spd100 20 > 40 (never stopped) But, remember that the speed changes are smoothed and overlapped. For instance, at 7 KPH, you getting some of SPD20's...

I've been running X01 chains since before I first posted about them, so a few years. Two Luna Apollos, with 1500 watt output, bikes are 70 lbs, I'm about 185 lbs, my wife is substantially less though. Climb hills as steep as 18%. Chain stretch has been minimal, and no breakage. I can't speak for...

Unless something has changed in the past couple of years, multiple tests have ranked the SRAM X01/XX01 12-spd chains as the longest lasting. See this post for instance...

Note that such mounting will affect how well the helmet performs - between the added weight and location of the camera on the visor, above your face/eyes.

I second the recommendation to get a new bike shop. Brake bleeding/fluid change is a standard maintenance item that any partially decent bike shop should be able to handle. As for when to change, Shimano says when the brakes feel spongy or the fluid color has changed. Unfortunately, to see the...

I recommend reading this older thread on Mid-Drive Chain Care. The 80% wear figure your bike shop said you had was hopefully based on chain stretch. The general rule is at 1% chain stretch, your chain is worn. Anything under 0.5% stretch and your chain is fine. Most advise replacing the chain...

Hi AndZab, thanks for looking into this. I personally find the Delta Voltage Table to be the most confusing part of Ultra tuning, as the table works backwards and each row is additive to the previous rows. So, it's certainly possible that I mis-stated something along the way. Let's look into...

I had a DM last month from someone tuning his uart Ultra motor, and seeing behaviors he attributed to the SPD torque tab being related to cadence instead of wheel rpm. Here's a test anyone can run to verify for themselves: 1) Save all your current settings so you can restore them after the test...

It's also important to note that both the display and the Bafang controller have their own independent settings for wheel diameter/circumference and speed limits. For Bafang (in the Basic tab), the Wheel Diameter works with the number of magnets you have (set via Speed Meter Signal setting) to...

Any reason a standard hardware store washer isn't good enough?

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.

And even then the direction of the threads would make that tighten, not loosen, the pedal. Hardest thing about pedal removal is remembering which way is loose on which pedal. Hint: Right pedal threads are the normal (right) way. Left pedal thread are the opposite (left to tighten).

The Frumpa pumps look really nice, if expensive. I just bought this on Prime Day sale: https://www.amazon.com/gp/product/B0CLTTB86X But I have big 27.5x3 tires to fill. For bigger, non-carry use, it's hard to beat the Lasfits: https://www.amazon.com/gp/product/B0CCJFMTCJ I carry that one in my...

In my experience, price related to comfort, not protection

Thought I'd post an update to what I have now: 1) Replaced the Weanas Grips with the PRUNUS Bike Grips: https://www.amazon.com/gp/product/B0756TM4CX The end hooks are great for a varied position or heavy climbing. 2) Upgraded the Cygolite 600 Metro to their Ranger 1400 model...

Chainguards are not there to prevent the chain from coming off the chainring. They're there to keep pants and such from getting caught between the chain and chainring, as well as getting greasy from rubbing against the chain on the ring. And since the Ultra is set up to have just one chainring...
