It's also fun in the first minutes of a good rain here, cuz it doesnt' happen very often, so when it does it washes a fair bit of oily stuff up into the surface of the water, and makes a hydroplane incident pretty much guaranteed sometime during a trip somewhere.

Thankfully, today I was riding the SB Cruiser trike, so I simply got to have fun drifting my turns rather than wiping out in them and getting run over by the following cars. :lol:

After reconnoitering my last accident, it looks like my studs lost traction where the ice and slush were on top of a painted direction arrow ... ?

I think my homemade studded tires offer (would have provided) an extra margin of traction on the leans.
Outer rows of screws rarely contact and present full ¼" sharp points to save a slide or delay somewhat, allowing time for something of a "controlled crash".

Is it the painted arrow, or the layered "sticker" (plastic with reflective stuff embedded in it)?

The former is very slick, but unless it's painted multiple layers thick, it's not usually thick enough to stop something pointy from grabbing in it. If it's mulitple layers it may actually catch in the layer on top but then when very cold it could fracture the layers apart and take the layer it's stuck in with it....

The plastic layered reflective stuff actually can stop the studs from sticking it in at all, AFAICT. (based on what I see when nails/metal debris/etc are on top of it and cars run them over; I see the stuff embedded in asphalt all around them but never in them).

Closer inspection ... looks like it was a reflective sticker type arrow.

Tungsten carbide studs are 1/16th inch "rods" with a similar 1/16" protrusion.
Not pointed, squared off.
Sufficient lean on crowned curve might present outer rows of studs as flat ski type surface.

But ... pushing 60 now ...
Bruises, strains and pains just don't heal up as fast or well. Getting reminders of every "unwise" occurrence whenever it gets cold.
Contemplating building a Winter eTrike.
Dual gear reduction 24V 350w motors for true posi-traction rear end.
2 x 350w @ 24V = 700w / 24V x 25.9V = 755w
A life preserving 4.15V charge should match the "Legal" 750w power output limit.
or
48.1V battery 28A controller through motors in series should provide a very torquey 10mph ...24.05V @ 28A - each motor
Serial parallel switch could switch to motors in parallel for 20mph cruising ... 48.1V @ 14A - each motor

Getting strange ideas about ski replacement up front ... or adding plow?

And when plastic/etc is cold, it is less easily poked into by the studs...even when they are very pointy.

Yes, this happens whenever the weather starts to change, for me (I think it is the air pressure changes, but I am not sure; I can feel it in my bones though, especially wherever damage has occured in the past).
Contemplating building a Winter eTrike.
Dual gear reduction 24V 350w motors for true posi-traction rear end.
This is part of why I went with dual rear motors on SB Cruiser trike...and why I like riding it more than the bike (aside from that its' much easier to haul whatever cargo I like with that). No matter how I feel, dizzy, tired, hurty, or normal, I can just ride. and if I can't ride at normal speed for whatever reason, I can go as slow as necessary without tipping over. ;)

A life preserving 4.15V charge should match the "Legal" 750w power output limit.
I'm very glad there's no power limit here in AZ. :)

Best I can offer is to ride with as low a pressure as you can, and as wide/fat a tire as possible. That's what I do for rainy conditions, is lower the front tire pressures to just above the point I end up spinning the tire on the rim from braking.

36V 17.6Ah Battery for ... Snow Beast, among other projects ...
Picked up a pile of Hoverboard batteries with HO Samsung cells.
36V 4.4Ah, so paralleled a few together.
4 fit nicely in sturdy, nicely insulated, Nintendo Gamecube bag.
Has substantial strap and quality stainless Steel clips!

Image

Attached V-A-W-AH meter to better monitor battery use and level.

Image

Still working on better quick release for throttle.
HO Samsung cells seem to resist cold weather sag nicely.
Will insulate better and run wires through small holes after concept further developed-proven.

Snow Beast is operational!
Cleaned and waxed all cables.
Freed up and lubed chains, brakes and derailleur.
Trued and tightened both wheels (spokes).

Test drove with my old 6 packer 33.3V 43.2Ah. (being replaced, gotta re-task for some worthy application).

As I ride in the winter in a balaclava that photo is not far off from a usual winter grocery day.
I must be a sucker for punishment .. as I wouldn't have it any other way it seems / is.
The car has not been insured for three years Ive been enjoying biking instead.

ebay has cheap electric gloves that work on ebike voltages if they work they would improve winter ebiking comfort.

36v , 48v , 60v for $10

Larger search for\of Heated Gloves

I would expect the cheaper gloves to have some heating element in palm or back of hand. "Best" should have heat into fingers and fingertips.

Will order a pair of 36V etc but also a pair of 12V blue to go with my Blue 12V heated Snowmobile helmet

Cheap gloves will supply a set watt of heat = hot on warmer days, cool on colder days.
Recommend adding digital "dimmer" (12-24V) for adjustment.

I ordered the black pair with luck the fingers employ a wire if not it would suck big time especially for the ole Thumb.

The seller I bought from sold them all under one voltage titled 36v 48v and 60v

from ad ~
Power: 8.5W each glove, 17W for one pair.
Voltage: 36V 48V 60V
Heats from 40°C to 45°C
Length of cable: 155mm

They sound like they self regulate the temperature

They might have a temp adjustment knob. I still have not received those grip heaters / battery warmers but they mentioned it has a "smart" temp control of some kind.

Found a photo of the wire , its a straight on/off switch

Image


Image

12v 48v 60-72v voltage. Smart switch control, easy installation.

Considering 3528 waterproof LED strip as heating element for fingers of gloves.
Embedded in silicone so very flexible, and supplied with dbl sided adhesive tape.
LEDs are 20% efficient, so 80% heat. Use 2s for low and 3s for high, or add digital dimmer.

I have a suspicion they half hastily fed the heating wire into the glove via the eyelet.
If so should be able to rearrange the heating wires with more care. I Imagine they used something long and thin with a release clip to set the wires in place.
A surgical clip or some such thing
Im also thinking could add more wire if needed

If light gets trapped inside glove then it eventually will be converted to heat as well. So 100% efficient in this application.

The heated gloves made here today first thing I did was check them for wires on the thumb. They have a wire for the thumb and all the fingers.

They came with the same Logo as the photo and fit snug not bad if you have medium hands if you wear a large they will be tight.

Function over fashion
I'm not afraid to look like some Eskimo, if it means being comfortable. (-10ºF this morning)
There can be a simple item and a world of difference between comfortable and miserable!

Hat - Knit cap allows too much wind, felt lined knit cap preferred
Goggles - snowflakes hurt hitting eyeballs
Balaclava - adjusts from around neck to over nose, ears too - scarf as substitute - works as rebreather, pre-warms air
Insulated shoes-boots
Wool socks
Thermal underwear
Mittens over gloves - windproof exterior with thermal insulating lining

Wind proofing is of ultimate importance
Wool gloves inside windproof insulated mittens
Felt scarf across face - knit allows too much wind

Basic
Creamy petroleum jelly, coat face, hands ... any exposed surface ( let dry several minutes, has water to spread-absorb evenly
exercise before going outside - prime internal heater
pedal to help keep body producing warmth

Emergency
Newspaper, shopping bag or store flyer between layers
Carry large handkerchief as emergency scarf

Personal Warm-up Recipe
Heat 1 cup water
add
1tsp chicken bouillon powder or cube
1/4 tsp garlic powder
±1/16 tsp cayenne pepper
Sip-drink while hot, gulp sediments with last of liquid
prepare for internal heat and cleansed sinuses!
