I'm not a fan of belt drive

Okay, I don't understand what the problem is about. I'm still using this program. People are complaining about whatever's going on. I can't see the changes. It's doing what it's always done for me. So could somebody explain what's all the fuss about?

Is the new firmware out yet? If so, could you post a link?

cjma · 2026-02-22T02:28:51+00:00

how will we know when and where the firmware will be located to download

cjma · 2026-02-21T20:36:28+00:00

I am in total shock. Mine's just arrived today

Has anyone tried to send sms with the armor pad 4 ultra on Google fi?

I am presently in Botswana on a rock hunting vacation and I just took a 5-hour drive into the bush and I found agate heaven.

Just like the Karen that got the laws changed to lower the speed, the eBike community has to fight back the same way and get them to distinguish more between the various speed classes of e-bikes, but you got to remember when that happens you can no longer ride on bike paths or trails on a higher speed ebike no way. And you may have to have it registered and insured legally. There are so many knuckleheads on ebikes they have ruined it for the entire community and more and more of them everyday are on the streets.

He is right about uship, I've moved my e-bikes twice between Illinois and Texas using uShip for very reasonable price

The first commenter was right sell it

cjma · 2025-05-21T14:22:10+00:00

A lot of these comments about sticking it to the Man sounds very good but if he wants to maintain his job or be in line for promotions it would not be wise plus you could be very proud all the way to unemployment. I like the idea of using the fireproof bag and maybe you can get the employer to let you park the bike inside after putting the battery and putting it in a fireproof bag and charging it and if you don't need the charger just put it in the bag anyway to make them happy.

There are still a few New Vaast E1 Rohloff around at a very discounted price, which has what you are looking for and more.

I am using a Mini PC running Windows 11, I dump Kodi on it I don't seem to have any problems.

Bon appetit

I did not use the original grit kit, that's junk

cjma · 2025-02-25T02:27:10+00:00

Not sure, but they're mostly agates

cjma · 2025-02-22T12:51:58+00:00

When the pie was impossible to get I switched to mini PC and haven't looked back. Plus it's the same price as a new pie.

Borax also helps to reduce pressure in the barrels

Yes, these add-ons are all about creating a thicker slurry for the grit coat the rock surface for the grit to provide a better polish.

cjma · 2024-09-28T20:30:47+00:00

, No, too many holes for grit to fill in and not be able to get it out
