RE: PH2: E-Bike Races To Podium
Discussion
Quite heavy and its amazing how quiet they are. I would not have one on the road for safety reasons. People don't see me so I make sure they hear me. You will have pedestrians walking out infront of you all the time on an Elec bike. Although not silent in the least, they are an uncommon sound and will most likley be ignored, though some may hear and think "what the...?"
All the same, Can't beat the sound of a decent engine and exaust note.

The problem with electricity is just the recharge time, performance and range should be able to match and exceed IC easily with developement (this bike was clearly no slouch!)- remember how far behind electric transport is compares to IC!
the bike may have been no slouch but we all know what happened to the Hare! That particular bike would not be any good in an Endurance race.I know they have to start somewhere, but maybe the time would be better spent (and the money)on developing the range and the reduced charging time to make electric cars a viable proposition for those who have more than a 50 mile range to cover each day.
As for your comment on electricity being Greener and Cheaper than petrol or deisel, it may well be, but it is highly irrelevant if I have 200 miles a day to cover!

yes at £26k for the basic bike without the extras needed to make it road going they will sell like hot cakes You'd imagine wrong then. http://www.mavizen.com/TTX02.html

The fairest way to compare them is let both vehicles start the race with the same amount of energy on board... petrol or electric can be measured in joules. Although I have a feeling this would give the electric bike a HUGE advantage given that they don't waste anywhere near as much energy in heat etc.
gasoline 45mJ/kgLiPo (at current mean dev) 600kJ/kg
hence gasoline has approx 75x bettery energy density
18 litres of gasoline (typical bike capacity) = 632mJ !! (approx 14 kg)
TT electic race bike had 12.5kWh battery = 45mJ (approx 75kg)
gasoline bike would only need 1.3kg of fuel to match the electic bikes energy capacity.
BUT yes, if the idea was to get the furthest on the energy was the idea, the electric bike would eventually get the farthest (due to its higher overall efficiency) (although technically, we need to include the battery charging losses too (as you don't tend to loose much energy between filler nozzle and tank with gasoline (unless you're a poor shot with the pump nozzle lol).

Yes, and do you know how much? Lets put it this way, a brand new R1 is a bargain compared to these.You'd imagine wrong then. http://www.mavizen.com/TTX02.html

As said before, these are not the way forward.
We are supposed to be looking for a replacement to fossil fuelled vehicles. Pray tell me, how is most of the electricity produced in this country?
Added to that, what about using them to cover a large distance? There was an article on the early BBC news last week where a driver attempted to get from London to Edingburgh in an electric mini - it took him four and a half days!

From a wiki site...figures from 2004 showing how our electricity was produced
gas – 39.93% (0.05% in 1990)
coal – 33.08% (67.22% in 1990)
nuclear – 19.26% (18.97% in 1990)
renewables – 3.55% (0% in 1990)
hydroelectric – 1.10% (2.55% in 1990)
imports – 1.96% (3.85% in 1990)
oil – 1.12% (6.82% in 1990)
Makes glum reading for you lentil eaters.
I'd love to have a go one one. I think there would be a whole world of difference between the electric and a normal bike both good and bad. If the prices came down they would make superb track bikes and if popularity grew we could see things like new tracks opening up that allow electric machines only (closer to cities and the like. clearly many many moons away but I'll watch with interest.
Just out of curiosity, how much do one of these bikes currently cost?

As the tech improves so will the batteries. Or they will design a method where you could replace the entire battery pack in 20 mins or so - possibly quicker. The sound is always going to be an issue, especially for someone who has lived a breathed bikes all their lives but I'd still love to have a go on one. I think on the roads the whole sound thing would be dangerous hence the whole track bike thing. However, it doesn't really matter as at 25K there isn't going to be very many takers

The network must have enough spinning reserve in the system to cover wind dropping out of the system (the wind stops blowing) so in order to generate 1Mw of an unstable source i.e. wind power you must also generate the same in spinning reserve from another stable source i.e. nuke

Did I read somewhere that this new type of "steel forests" actually failed to generate any significant contribution to the national grid during the Nov/December sustained winter weather ?
Amazing for all the hype, not to mention £squillions we've been conned into throwing at it.
And if it wasnt for all the subsidies then it would not be economically viable to generate electricity from wind, so when your paying your fuel bills next just remember that you have already paid it once in your taxAmazing for all the hype, not to mention £squillions we've been conned into throwing at it.
