That is the strangest thing.
Otherwise, I would've suggested checking out the adjustment of the motor cut-off switch built into the right brake lever. It's in the vicinity of the throttle, and if the cut-off switch is just on the threshold of switching off, it may be jostled by twisting the throttle.

A voltage can be applied to a motor, but you can't really "apply wattage" to the motor.
Wattage is a measure of Power, and Power = Voltage x Current

For a watt meter to work, some current has to be going through something and then multiplied by the voltage to get power in watts, unlike with a volt meter which can measure voltage across an open circuit.

In this case, it may be that the current is passing through something other than the motor, but which the controller assumes is the motor. Some kind of short circuit in the wiring perhaps, or some path through the motor that does not result in it turning.

General Chat / Re: RadRunner 2 with a dog trailer?
April 25, 2024, 05:06:32 PM
With a dog that size, I think you're going about it completely backwards.
This is what you should get:

The dog would probably enjoy it more too, once in a while. ;)

Quote from: Muskie1 on September 23, 2022, 10:46:57 AMThe problem with a trailer is any axle mount. The warranty is voided.
I don't see why they don't make more of them with hitches to the centre of the rear rack. Then you could make tighter turns in both directions.

Used e-bike without the charger?

How confident are you that it was not stolen? A charger is the one part a bike thief would not have gotten.

There are two RadRover 6 plus listed as stolen at https://project529.com/garage

Quote from: hondo2160 on April 20, 2024, 03:34:06 PMThis is a bummer. A replacement unit is $80. I guess cable ties will do for now.
Yup.
There was a popular novel in the '70s, Zen and the Art of Motorcycle Maintenance by Robert Persig. Part of it is the story of a road trip with his buddy.
His buddy had this deluxe BMW touring bike and was complaining about how one of the brake handles or something was slipping, and it was so far to the next BMW authorized service centre. The author offered to fix it by cutting a shim from a soda can and installing it. The very idea of it horrified his buddy because it wasn't an Official BMW Brass Shim. He preferred to put up with the slipping for the duration.

After skimming through the assembly video, it doesn't appear that you can.
You could adjust the angle but that's about it.

I suppose you could replace theme with BMX-style handlebars (of appropriate diameter), which come in a range of heights ...

... but then you could run into the problem of straining the cables and wiring, or them not being able to reach the handlebar and all, especially when turning.

Or maybe keep the stock handlebar and get an extension for it like this sort of thing:



Again there's still the issue of the cables and wiring being long enough.

Quote from: John Rose on April 17, 2024, 04:53:53 PMThe link and the description look like two completely different horns. How is the one in the Amazon link "self powered and charging"?

https://drive.google.com/file/d/1_Kp8siD21_X5L4mnxeAQvBFUBMc_H-TC/view?usp=drivesdk

For some reason the pictures didn't upload to my post. It's a custom made solution that uses a basic horn (Amazon link). Then there's a 3D printed case that houses the charging circuit and battery.

There are lots of products available that offer a turn key solution of this, I just wanted to make my own.

Ah. It all makes sense now.

I carry a small manual pump that mounts under my water bottle holder. I don't recall it being too much effort to pump up a 20" fat tire.
A CO2 cartridge seems to me the poorest choice, if you have a chronic leak. What do you do when it runs out?
At home I have an 120V AC-powered pump for the cars and the bikes:

And, since I can never trust the gauges built into pumps, an inline pressure gauge with a handy little bleed valve:

What? Completely deflate the tire, push the bead in along a short section, pull out the part of the tube with the hole (if you know where it is). Patch it, push it back in and re-inflate.

- Custom Self Powered and Charging Horn
Very nice for getting car's attention. Custom 3d printed case that attaches to the front rack mounts. Charges with the USB port on the display. This took a while to figure out. It has a small 500mah battery that is kept topped off by the USB port using a small LiPo charging board. The button is wired to power the horn from the 3.7v nominal battery, which powers the horn. The horn is rated for 6V, so it's not as loud as it could be.
The link and the description look like two completely different horns. How is the one in the Amazon link "self powered and charging"?

That ain't necessarily so.
I shave with razors that are 50-100 years old, they out-perform modern cartridge and disposable razors, and (most amazing of all) you can still get blades for them, at a cost of a penny or two per shave. I have a few modern ones too, but they're styled after the vintage ones and have interchangeable parts.
My 40-year old electric kitchen stove is primitive too but you can still repair it.

I just noticed that the automatically-added "Rad's New Lineup Is Here" final post is gone now.
Not that I'm complaining.

Quote from: Naranja_CT5+ on April 16, 2024, 07:53:35 PMIf you cannot find a replacement bracket why not try using a cellphone mount?
I don't think you could find one small enough for the UI Remote.
Also, the button-mashing subjects it to considerably more force than tapping on a touch screen.

One of my favourite (even more so than duct tape) DIY sekrit weapons is plumbers strapping. It typically looks like this:



Super strong, yet easy to cut with metal shears or bolt cutters and easy to bend by hand or with pliers. It comes in various widths and materials, such as mild steel, copper, and galvanized steel. Of interest for this project is the kind that is coated with PVC, so as to minimize scratching the finish on the handlebar.

The smaller holes should be big enough to get the threaded part of the screws through, but small enough for the heads not top slip through. You could also use washers with it too.

Maybe not very elegant to look at, but it should be secure enough until you find a 3D-printed one.

Or, you might get lucky and find one of these molded PVC pipe straps in the right diameter, or slightly bigger:

It should be on a shelf near the other kind of strap. If it's slightly bigger diameter then you can put a strip of inner tube rubber on the inside, or build it up with PVC tape.
[edit] Oops. It just occurred to me now that the part you are trying to replace fits around half the diameter of the handlebar, so it's only a half circle on the inside. The PVC pipe strap is designed to fit the full diameter of a pipe, so it's a half circle plus parallel extensions. A sheet metal one could be more easily bent to fit.

Oh - If you do have one printed, and it's printed with filament, have it be printed on its side (not upright like an arch), because the horizontal layers are more easily split than the other uh ... directions? ... dimensions?.
If it's a resin printer, then I have no idea.
