I have done some work with Agility on its electric bike.
There are several marks jumping on the bandwagon but as of yet none come up to the plate, sorry for using a USA saying.
The one shown looks the part until you look at a couple of points, one the range (75 miles) which is quoted as an average, so riden hard it may well halve, and secondly the bloody price.
When they can get the range to 150 miles then I will prick up my ears but at the moment it makes no sense. With most modern bikes doing reasonable miles to the gallon I fear it will be a long time before these things are anything else than rich guys toys and green nana nana nas.

PS If you have ever one one of these then give me my Bandit and a nice can any day, perhaps they could put a speaker on the front so you play the engine noise of choice but there again it would damage the range.

Looks like they bought a Hyo Sung, threw away the engine and fitted a washing machine motor and a tractor battery.

this only makes sense in combination with a hydrogen fuel cell charging the battery...

One lapped the isle of man last week at 99mph. and went through the sulby speed trap at 144mph.
This was with a certain mr Rutter as its pilot.
Ok i was only 1 lap but the potential is there.
And just to put it into context i very much doubt that many on this site could get anywhere near that on a laverda.

It's only battery technology which is holding these bikes back, or more specifically, the current cost of the battery technology. The acceleration of an electric powered bike with a suitable motor is astonishing, bear in mind that that they can make maximum torque from virtually zero revs. Rutter described his bike as feeling like his Ducati in second gear every time he opened the throttle. I reckon Rutter's Ducati must have impressive acceleration in second gear so his comments give a pretty good idea of the performance on offer.
On e of the most impressive electric bikes I've ridden is an electric powered trials bike
Here's an interesting report on an electric drag bike

I don't believe any Laverda triple has lapped the IOM at 99mph (92 or 96 from dim memory).
For sure the electric revolution depends on not only longer battery life but also fast recharging and low weight. It will surely come as the big players in the US are having to get serious about it since being baled out by Obama.
Just plug a soundtrack for a triple into your iPod or whatever and pretend you are ripping up the neighbourhood.

So that lead me to re-read the obituary of one Barry (Baza) Raymond Roberts whose funeral the CLQ recently went to where it said he went around the IOM course sitting backwards on what I believe was a Lav triple and averaged 91mph. Now considering he raced in IOM 15 times I would be surprised if he didn't go faster than that even on a Laverda. I'm not sure what bikes he used for forward sitting races but I'm sure someone here does. Still 91 backwards is pretty good!
BTW I agree, you'd need at least a 2-300K distance reasonable fast to be attractive here in OZ.

Here is one we have in the shed DKWs effort the power (loosely termed) seems to be on or off but because the motor is over a certain power it has to taxed , MOTd and insured
I may have ventured out on it if it wasn't going to cost me and it is orange

Not sure about that, 91mph average only looking where you been is a bit unlikely I recon. If he did then bloody good on him, but to average over 90 you got to spend a lot of the lap over a good bit over 100, they take a bit of hanging on to at those sort of speeds even whilst sitting the right way around.

Drikko, Far be it from me to dishonour any of Baza Roberts considerable achievements on motorcycles but I think you might have duff information regarding Barry's backward riding exploits. Barry completed three forward facing TTs aboard Laverda triples and his respective average race speeds were 93.68, 91.44 and 83.21mph. I would imagine that the lowest speed of 83mph was a wet race. Some individual laps will have been quicker, possibly around 100mph
I think it's pretty clear from these speeds that lapping at 91mph backwards wouldn't have been possible, in fact I doubt if the timing gear would even be operable on a stunt like that.
Barry may well have ridden a Laverda triple backwards at 91mph, which in itself is a quite a feat, but a lap of the TT course at 91mph sat backwards up on the fuel tank from a standing start? I don't think so... I hope I'm wrong about this .

I was just reading what his family wrote. Tis all. I didn't personally know him, just provided one of the Laverdas at his funeral.
Looks like the fastest Laverda around IoM was 99.56 according to:-

Remember those speeds are average race speeds including pit stops etc. Some individual lap speeds will be faster of course, particularly [but not always] the flying laps. The fastest race average of 99mph was Malc Wheeler, nowadays editor of Classic Racer, riding the Cleve Brightman Montjuic in the F2 race. Malcs fastest lap was over 105mph. Read all about in Malcolm's own words here; http://www.laverda500.cc/mylaverdayears.php
It's a curious anomaly that them little 500 [and 600cc versions] of the Montjuic/F500 did so well compared to the triples on such a fast circuit. Or maybe it was simply that Malc Wheeler is an exceptional rider. The established triples pilots such as Roberts and Davies went a wee bit slower on the 5oos than they did on the triples.
