Yep I agree with all the examples zzsstt.
If I was riding regularly in the kind of conditions in your examples A thin fiberglass or carbon fiber pole with a flag or even better adhesive strip of 100 super bright LED lights that could strobe running the length of the pole. A simple dc-dc converter off the main battery pack. I agree in high risk conditions it would be a must do for my own safety. Not hard to overcome any safety issues. Actually summer night time riding is even safer with dual 1600lm lights on the front and another at the rear people think I am a car. All of my wheels have a glass fibber reflective tape on the sides so the bike really stands out.
Lately the bike has just been used for some short social rides and the odd trip into town to get milk
. Though I do plan on doing some much longer overnight or even several day adventures as the weather is getting better so will look into upgrading the safety - visibility for that.
My plan for long distance multiple day rides is to use the boby trailer behind the trike. The trailer will hold my small hiking tent, sleeping bag, stove and generally what you would take for over night hiking trips. Although I wouldn't need any considerable food or water just snacks and a water bottle.
In the center of my rear trunk bag would have one of my old 36v 20ah lifepo4 packs and my charger. The trailer would hold my other 20ah 36v pack. I will then have more storage in the two drop down bags on the rear rack. Food can be picked up from small country downs on my way through and stored in the bags until the evening
If i program the bikes computer to limit max amps and use cruse control I consume around 8wh - km averaging 30kmh with only light - easy steady peddling. I would have around 1500wh of battery all up but like to only consume around 1200wh befor charging. That gives me a 150km range each day with all my gear. 5hrs of riding each day at 30kmh. Perhaps 2 1/2 in the morning then 2 1/2 in the evening.I don't need to do 150km each day but just what ever it took to get to the next camp. I would camp up for the night at caravan parks and pay the extra $5 for a 240v powered sight or better still get a normal non powered sight and get friendly with some one and slip them $2 to charge my bike from there plug. The bike would be ready for another 150km the next day. Opportunity charging is available in some parks, coffee shops and so on. If you ask nicely and pay a small tip to cover your 10 - 20c of electricity.
There is one guy who rode his ebike 7000km across Canada. Charging each night at motel or prearranged friends house. Over there the have mains outlest at some car parks to plug in car engine heaters so he was able to charge from them. Even the odd powered road boards.
Its a long video but if you have some time he gives a presentation on his 700km trip.Its very interesting .Justin actual own a ebike shop and is a very modest yet smart guy. he designed the electric bike computer I have on my bike.http://www.youtube.com/watch?v=oCvo6ffWRdE&feature=player_detailpage
I am going to give it a trail run on a short 50km - 100 km return ride from Maleny to Kenilworth. Just as a chance to test the bike with all the gear and record some consumption data and camp by the river over night. Might even get my wife and daughter to drive the 4wd and camper van and meet me there. I would still pack my own tent and gear just to get a feel for the packed weight.
Then if turns out good I will plan a 500km - 1000km trip in the future when I have a free week.
