BTW, I finally got my wife to try out the Sena M1 Evo this past couple of weeks. After some fiddling with the pads, she likes it. She was concerned about the additional weight, but in use that hasn't been a problem for her. We really like being about to chat during the ride and where/when to...

Does the Bikom connect to Sena’s M1 Evo bike helmet mesh system?

I'd like to hear more about that. With the EggRider at least, I find no differences between Sport and Eco (aka Off-Road and Road) when everything we can set is set to the same.

I agree, but we're talking about chains actually breaking, and yet people being happy. Makes no sense to me.

Actually, I believe the Satiator maintains a tiny trickle current to keep the battery at its percentage once reached.

I can’t imagine being happy about a chain breaking. Especially if you’ve been checking for wear (elongation) and it wasn’t well past 1% stretch.

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?
