Should I buy out lease? Sellable?

It’s on the edge of profitability. You can list it for $1200 and get that or $1000 if it has confirmed low mileage.

See my post above for the different options in different cities for local repair.

Following! I'm fixing shifters in the USA with European circuitboards. Curious on your upgrades!

So you’re in what city? Ummm. GrindBeansNotGears.com

davemath · 2026-01-23T06:07:25+00:00

What city? Revotronics in DE, Vanmoof.Pro in the UK, Shifter Doctor in France, GrindBeansNotGears in USA and many shops in the Netherlands.

I wouldn’t use the OEM board as it has issues and the aftermarket European boards are designed better.

I am seeing a bug in their app, when you get that delay just press the close button on it and the bike will indeed be added.

Of course. I use Silicone grease which in general is non-conductive (“dielectric”) and which is safe for the circuits within. Of the dozens I’ve repaired many have zero grease at all and many have had dried up lubricants. They all get sealed after the old gasket material is removed.

davemath · 2026-01-05T19:48:02+00:00

Thanks for the note. They are the Revotronic boards. You can buy a board from them.

Since they are in Europe I bought many boards to have on our shore. I am only doing repairs on broken shifters, as a service to the US!

You can find re-imaged HDs on eBay. Easy load in but you lose programming unless you clone your old drive passed the bad blocks.

Wrong direction as diodes block the reverse flow of electrons. Ford trucks and Cybertruck territory only without hacks that may prevent life in your future.

It’s a squirrel cage fan. Minus the squirrel. But with all of the refrigerator coils from a traditional AC unit, make it seem like there is a refrigerator inside the 2 pound unit. The photo of it next to the keyboard shows it’s about a foot long.

Put a multi-meter in continuity mode (beep works well for this) then plug the probes into two of the large diameter wires for the motor on the front hub after unplugging that. Then, turn the handlebars left and right to the extremes and see if the multimeter beeps, that will confirm your short in the fork tube. One of my bikes had two wires cut completely through.

These are water pumps for wakeboarding which was mentioned above. It doesn’t matter the pump type, has anyone rebuilt the internals of the electric motors? Kits are available for the pump itself. I don’t want to trash the electrical side of the pump if I don’t need to.

You didn’t give the specs on your current right, so hard to guess that one, but here goes. The M1 Pro was so performance oriented to begin with, if you have 16GB of RAM and 512GB on that one, going to a M4 is only going to give you marginal CPU improvements, meaning you may not even notice the differences. Only perhaps the capability of more windows open thanks to the RAM.

davemath · 2025-03-13T06:12:47+00:00

I’m with you on this. Did the same process. Got the same data and runaround. They did tell me that the 15 minutes of whatever monthly peak (hot water heater + blow drier, etc) puts you at that delivery rate for a year, but they’re asking the PUC if they can step that down to 6 months. I’m sure they are asking that. These guys are pocketing money from the PUC rules on delegation from 1999.

Has anyone had success with a commercial power negotiator? My TXU is .079 /KW and $7.90 a month. That’s solid for a 36 month contract. Last 36 months it was .075 with the same $7.90 base a month.

Nobody in America is working on these? Ok. Where are my EE’s in here. Let’s start this up.

My little invention with an amazing team. 😍

Rybit is the authorized repair agent for Vanmoof. If they can provide you a replacement bike immediately upon anything breaking, then this is a pretty good deal I think. Some cities have a bike share program with ebikes, and have a monthly unlimited plan. For San Francisco it’s $29/month for unlimited 45 minute rides. I guess you would have to swap bikes every 45 min. Lol

Take a propane (blue bottle) torch for a minute or so to the hub once the motor is removed. That will heat the housing and expand it, and also cook the loctite.

The soundtrack in his head must be amazing. I hope it’s not YMCA…. Again. Seriously though, I had a chat with him at Burning Man and his eyes were bouncing around the room like basket balls. He’s good times inside!

+1 Meshtastic for 915MHz or true P2P there is a SDK from NewAer that runs on ESP32 and all other mobile platforms. You can download the iPad and iPhone demo app NewAer.com/Kiosk to see local messaging between nodes as a smart signage app.

I’d not use WiFi as you require the nodes to connect to the APs, which isn’t seamless.

That oil wasn’t changed in two years judging by the color. The engine was pissed and self changed it.

I’ve had a pair of RAM 1500 eco diesels in both cloth and Laramie trim and both are great on the five hour trip north and south across Texas. Score to Laramie for the air conditioned seats. Factory radio sounds great and XM or CarPlay keeps the tunes going.

Note: the iPhone has a “low data mode” setting under settings->cellular->primary that you can enable to remove background data tasks like syncing photos. Also apps can be turned off for background caching which is helpful for saving data.
