Ebikes are not fast enough yet.
They need to be MORE DANGEROUS.

If you used the family car for just yourself then you were simply wasting.John in CR said:Regarding efficiency, BS. My ebike has replaced use of our family car by 90-95%, so instead of about $2k in gas per year, I use less than $30 in electricity for the bulk of our family transport.
SamTexas said:That's ridiculous.John in CR said:..., and I'm definitely safer on my high speed ebike, and that includes you riding in your car.
Ypedal said:good DH bikes are plenty capable of taking 30+ mph.. my norco being mid-low end dh is very stable at 35mph and mechanidal brakes with 8" rotors stop me on a dime when need be..
but over 35 requires good roads and suitable areas, there are posted speed limits everywhere and i believe we should obey those, no need to have seperate limits for ebikes imo.. ride safe ride sensible.

I'm sure someone on here knows the proper figures... ;^)

That's about the number I've read too, which puts it on par with modern ICE's, though the human will probably win out with the more efficient drive train to the wheel. When you factor in all the extra weight an ICE hauls around to move you, then the bike wins running away. Fuels cost jumps up to bite you though, because food as fuel is darn expensive, and makes the ebike the most efficient form of transportation known to man. An ebike is in the neighborhood of 60-70% overall efficiency from the electrical socket to power at the wheel, and electricity as fuel is in gasoline's ballpark in terms of price (a US gallon contains 36.6kwh of energy).

OK, it can't be done everywhere, but none better free energy yet...
I calculated that if I'd live on a 46th floor, I could sail to work from my balcony!neptronix said:MadRhino said:What about sailing? 8)neptronix said:Hell yeah. This is the most efficient form of transport, beating even walking or running.

Hey man, if you can sail to work, by all means, git 'r done. :lol:

Something is very efficient with the wind: It's not lost in usage. Unlike other forms of energy, that dissipate in heat or burn in fumes, the wind is still there to use by someone else.John in CR said:You're thinking of cost efficiency, not the machine's efficiency (power output/power input)
No and no. Yes it would be a joke. I can't tell if you can differentiate between speed limit and motor assisted limit? Appears to me you attempted mix them up to cloud the issue.Ypedal said:Should cars be limited to 110 km/h ( max highway speed in this province ) ?.. how about sensors in cities that prevent cars from exceeding posted speed lmits ? lol.. that would be a joke..
SamTexas said:Unless you're Lance Armstrong, your sustained speed on a regular bike is around 16mph,
I can too, but I can't sustain that speed for a long time. And true "on the flats" only exist in short distance before you hit some inclines or winds which will significantly lower your speed.theRealFury said:Well I’m certainly no Lance Armstrong, I don’t wear Lycia and I’m no muscle bound lout either but I find it very easy to cycle on the flats at 18-22mph unassisted.
Did you read my initial post? Why are you so defensive? And please, do not talk to me about voting politicians out of the office. People who talk big like yourself are the least likely to vote. Save your big, vulgar language for face to face conversation, you might find out that people don't like it and have a way to respond to it.number1cruncher said:Why not?
If your argument is that they are dangerous, then don't ride one. If you are concerned your local officials are going to ban all ebikes because of a few fast ones, vote the imbeciles out of office.
To assume that every creation you see on this site is being ridden on the road is short-sighted. Do you assume that all ice dirt bikes are ridden on the road? Of course not, because they are special purpose vehicles.
I am getting tired of nanny-state tactics that add no value to our society. Maybe we should make bleach illegal because it could be consumed by an idiot? Or make water illegal because we may all drown in it? Where does this nonsense stop? :x
Wow! Thanks for that video.northernmike said:Ebikes are not fast enough yet.

You carry up to 4 people on a bicycle, 3 of them are your own kids, traveling at very high speed, and you talk about better safety compared to riding a car. Sorry John! Like I said before, you're are BSing yourself. And no, I don't want to have a bet with you. In fact, I don't really want to read/hear anything about you and your sick logic anymore.John in CR said:No it's not apples and oranges at all. It's the primary transportation for our family. It's the school bus for our 2 boys except on the days weather prevents it. My 15 year old daughter occasionally will hop on the rear rack making it four of us on the bike at once. That's 250lb me + 75lb + 45lb +100lb.
....
You better go check the statistics. You're confusing exposure or risk in the event of an accident with safety.
....
You really don't appreciate the performance potential of an ebike. I can make some fairly small changes to make my bike beat your Z from 0 to 60mph, and I'm talking about my cargo school taxi bike. If you care to challenge that statement, let's make it interesting. It's already what, about 20 times as efficient, but better in terms of useful acceleration would be a real slap in the face that I believe is warranted based on the attitude toward ebikes that you've demonstrated above.
After you lose the 0-60, I'll even let you go double or nothing and do a rolling start kind of thing, say 20-60mph, where my ebike would have an even greater advantage over your heavy ice wagon.

You're correct that better efficiency has NO or NEGLIGIGLE effect on the electricity cost required to recharge the battery. It makes no difference (that we care) whether it costs 1.5p or 2.0p, or 25% saving.theRealFury said:with regards to efficiency, i already think that ebikes are so efficient that any further efficiency gains would be small enough to go un-noticed. I did 17 miles the other day and used 2p (~$0.03) of electricity, the ONLY place that i want to see increases in efficiency on ebikes is battery capacity/weight ratio.

I can't agree more with you. Yes, the track, the dirt and private property are the places for high speed ebikes.
