I haven't needed to buy this yet (planning on a controller upgrade in a few weeks, so doing my homework just in case) but I believe this one will work and it's not expensive:

Note that the page has several different types of cable to scroll through.

I agree that the stock headlight (and even the optional "premium" light, which is not) is pretty useless except as a running light.

I use this one and am extremely happy with it: https://amzn.to/3ts7cuh
Mounts securely, but pops right off for charging or for use as a handheld flashlight.

I use this ABUS lock, which is a beast and has an inside-shackle length of about 11.5" - should clear the width of fat tire/wheel too, but measure to be sure.

I think you need to move, man.  What did you do to be sentenced to live in a place that's so worrisome?

For what it's worth, this Sena costs more than the cheap helmets but is well made and certified; the bluetooth audio also works well.  Like you, I want over-ear speakers so I stay aware of the world around me.  I use it almost exclusively to listen to podcasts and receive the rare phone call, don't need or use the intercom feature.  Audio is a little tinny as you'd expect from such tiny speakers, but they're fine for podcast and phone voices.  Battery life is also good; several hours on a charge.  I also bought the visor, which is optional on this model and really comes in handy near sunset.

If you can squeeze out the price money, I think it's worth it and you'd be hard-pressed to find similar quality and features under $100 IMHO.  I got the white one "used like new" for $103 and it was new in the box, so that wasn't bad at all.  If you're not in a hurry, use camelcamelcamel.com to set up a price watch on it for eventual lower prices.

I installed these on my MiniST a few months ago (wanted a better, more-rubbery grip - I think the stock grips look nice but are far too slippery) and have been very happy with them.  They fit perfectly, look good and even have a cut-line in just the right place on the grip for trimming with a boxcutter, hacksaw or other decent knife to size for use with a twist throttle.  They are a very nice upgrade IMHO.  Put a little effort into trimming the right-side grip cleanly after you make the cut, for best appearance and so you can snug it up right against the throttle.

https://amzn.to/34UzkMl

Tip: before installing, clean both the bar and the inside of the grip with rubbing alcohol and let it evaporate.  Then spray the bar with a heavy-duty-hold hairspray (I taped a plastic bag over the throttle, brake assembly and bar to catch any overspray) and slide the grips into the right position; you'll have a little time before it starts to set up, so sit on the bike in riding position and put them where you want them.  Let them be for a couple of days for the spray to evaporate from the bar surface; at that point they should be as solid as a rock, yet still removable if necessary.  Mine have never shifted after the spray was fully set, but if you try riding with them too soon they will probably break loose and never get completely tight on the bar afterward.  I had to remove and re-spray one of mine to discover that fact.

It might be dependent on the tires you have mounted.  If you're looking for accuracy, I recommend putting your phone into GPS speed mode and compare its reading against the bike's display on a level surface after giving it a few seconds to stabilize.  Then adjust tire size in the settings until you get the closest match.

My MiniST has an optionally-flashing rear light included from the factory, but here are two great alternatives that I've also added to my bike - the front light on an accessory-bar attached to the main handlebar and the rear one strapped to the underside of my Cloud-9 seat.  Both of these need to be recharged occasionally, but both have very long operating times if you select flashing or slow-strobing mode.  In addition, the rear one is motion sensitive to turn on/off automatically so I need never touch it until I pull it off for a recharge.

I typically hook these up for recharging when I charge the main bike battery, sometime every-other time.  Both are highly recommended, very bright/visible, very functional and well worth their prices.  If you mount them properly, you WILL be noticed on the road.  Both mount securely but are easily popped-off for theft prevention or in the case of the front light, for use as a handheld flashlight.

Just a quick tip when you reinstall them, to keep them from loosening up when riding, spray the handlebar with heavy-duty hairspray, which is just enough of a "glue" to hold them but still make them removable again.  Give them a day or two for the spray to fully evaporate and set - they won't be solid at first, but that's good for final adjustment to the best position.  I swapped out the stock grips on my MiniST for some good ones months ago and this worked great for me; they're still solid as a rock.

I wouldn't use a screwdriver to loosen them up; you'll scratch up the finish on the bar.  I used a combination of an oil-filter strap wrench to loosen them up with some non-scratching torque, then an air compressor and pulling hard to remove them.  If you can "inflate" them a bit with a compressor, that will help a lot, but it's not easy and you'll have to be patient and keep tugging.

Quote from: Enkidu on January 05, 2022, 10:21:21 AMThis is Zack from southeast Michigan. I am considering getting either a RadMini Step-Thru 2, a RadMini 4 or electrifying my Bike Friday New World Tourist with a kit from Grin Technologies. Joined this forum to help me decide which way to go as I weigh the pros and cons of both systems.

Hi Zack, welcome!

If you decide to go with a Rad Mini, I highly recommend the Step-Through over the step-over model; I bought the ST and am extremely happy with it.  The frame is very strong to compensate for no upper bar and the arrangement of battery and controller is nicer IMHO especially if you ride in wet or muddy environments or want to add an aftermarket controller/display.  Plus that step-through frame is nice if you have any knee or hip problems, or have something large strapped to a rack on the back.  The one thing I never do with it is fold it, but nice to know I can if I ever need to.

I'd go so far as to say there is no reason at all to prefer the step-over version.  Unfortunately you've just missed a pretty big sale where it could be had for around $1,200 depending on the combined discounts, or $1,150 if buying two of them.  It's gone up $200 back to the old $1,500 price in the new year and we're expecting it to be replaced with a newer model, probably at a "newer" price as well.

Here's my current configuration with a few doo-dads I've added since getting it last March:

Quote from: barrelsonly on January 02, 2022, 10:25:32 AMOr is there any pre-made floor racks out there that might work?

Maybe these would be a bit bulky for your application (in width) and would need to be fastened down to the van floor, but reviews are good for stability and ease of use.  I asked about whether they'd support a rider without tipping over, for adjusting seat height with both feet on the pedals and similar applications, and the overwhelming response from owners was no.  But for holding the bike in place by itself, people seem to like it, and they're not expensive.

It'd probably be a good idea to post a question about how they might hold up with bikes loaded and then subjected to the swaying and bumps of road travel - these are typically used in stationary apps like garages.

Quote from: john in Idaho on January 04, 2022, 08:05:10 AMI have a countdown timer that i can set for up to 12 hours then it automatically shuts off.  But how long I set it for is just an educated(?) guess.

Shortly after I got my MiniST, I added a countdown timer to prevent forgetting about it being plugged in (probably can't hurt over a couple of days, but even Rad doesn't recommend leaving it connected indefinitely) and set it to 7 hours.  I almost never discharge below 2 bars (20-80% is the optimum range for battery longevity) and 7 hours will bring it to 100% every time no matter how much is discharged, then shuts down.  I asked a Rad tech about my 7-hour setting during a support call and they're cool with that.

I'm awaiting one of Peanutbutter's charging regulators so I can set it to 80% charge-to-shutoff for normal use but will occasionally take it back up to 100% for recommended rebalancing now and then or for expected long rides.

Brilliant!  Well-written and illustrated so that even us dumb mechanical engineers can understand.

Thanks and Happy New Year!

Thanks for that latest update, Ray, to help save the rest of us from running into the same headache.  So there are doublers behind the box to give the screws more to bite into?  That's a good design detail if so.

I looked at just popping off the ends and sealing them, but as I recall I noticed a gasket already there, so didn't bother.  As I mentioned, I don't ride in the wet and the MiniST controller mount is high up and toward the rear so I figure it'll be ok since the mfgr. would have been aware these things are used outside and would design accordingly.

Happy New Year!

Quote from: RayStDenis on December 31, 2021, 07:18:54 PMI'm in the process of waterproofing the controller as I can see several places where water could easily come in.

I've considered doing that as well, with some silicone sealant, but I don't ride in the rain, the MiniST's controller is mounted high enough to avoid puddle problems and my engineer brain keeps thinking that some moisture will accumulate inside from condensation over time and if it's well-sealed, how will that moisture ever get out, to avoid corrosion problems?

Would appreciate some input from others using this controller upgrade - does it get warm enough with ordinary use or sitting in the sun to drive any accumulated moisture out if sealant isn't applied?
