electric gasoline scooter

have a look round the site its interesting "petrol engined bikes."
not for us but the scooter may be the basis of something that would move people away from pure petrol drive.

Very interesting that this has now reached mopeds Mike.

The implementation is nowhere near the Toyota Prius sophistication though, just a crude switchover at 20 kph, so I'm not sure how much anyone would use the electric only mode, since that's only 12.5 mph.

It's ok to ride at that speed on the cycle crowded oriental city streets, but a moped at 12.5 mph on our roads would probably cause fury among car drivers. That would be especially true where there's a cycle lane on the side of the road since the moped can't use that so would really obstruct others.

In practice I think it would only momentarily see battery operation during the acceleration phase.

There are loads of them over in China!
We had a couple over to test out but has got no further at this point. I haven't actually ridden it myself on the road (no tax, insurance etc.) but the theory is good. A lot of petrol would be used when pulling away in an I/C engine, so it would cut down quite a lot on emmissions.
They might well take off, especially in London, eventually.

Please let us know your reactions if and when you do get a chance to try them out Carl.

I've seen it ridden, and you wouldn't know any difference to a normal moped, just obviously quieter at low speed!
Mopeds aren't quick anyway, so there wasn't much difference in the speed of it to a normal petrol one.
I guess you really wouldn't know any different if you are riding it compared to a normal one.

Thanks Carl. I can't help but wonder if there's a worthwhile overall saving, given that the time in electric mode is so brief and there's a restart with every pass through 12.5 mph.

Electric Bikes obstructing the carriageway

I think Flecc above had accidently (albeit briefly) fallen into the 'Motorist's Point of View'.
The roads are for everyone, pedestrians, horses (and carts) bicycles (whatever their means of propulsion), etc.
There are country roads without pavments where pedestrians may (must walk): quiet country roads where one may exercise one's horse (and very pleasurable it is too) - even, it transpires from the outcome of the case cited below, where cyclists may ride on the road even if there is a cycle path.
There was a very recent case reported in Cycle (Feb/Mar 2007 letters page 19) of a cyclist who was accused (by the police) and convicted of inconsiderate cycling. The conviction was eventually overturned with the help of CTC legal and substantial financial support.
Don't be intimidated by inconvenienced motorists: they wll arrive at their destination long before the 'green man': dead or alive!!

The gasoline driven bike

I had such a bike in 1997.
What are they like? Noisy; uncomfortable (vibrate like mad); unreliable; not very economical (100 mpg/one up - my Citroen Diesel does 55/58 mpg 4 up-this is not meant to start a contest on whose car does the most mpg) and have an expensive annual cost before one gets on the bike.
At speeds above 25 mph (or even below really) one must be totally commited to watching the road surface as well as all the other things that come at one from all sides and above.
Fitted to a good Mountain Bike they are quite stable at speeds one associates with racing cyclists.
BUT, just like Electric Bikes, they are great fun.

In other words Pete, they haven't changed since the 1950s, they were just as poor then, especially the vibration. IC engine vehicles need to be designed as an integrated whole.

Re: falling into the motorist's view.

My view is that confrontation on the roads or in road matters achieves nothing, and co-operation can achieve a lot. I've been riding bikes and motorbikes and driving cars most of my life. I've had considerable truck experience as well, and I enjoy walking and frequently walk several miles through town or country when going somewhere specific, with and without pavements and plenty of horses in this edge of London area.

Having worn all hats I can sympathise with each road user, so whatever role I'm in, I try to help others have a good journey experience. That's why each of my bikes has a mirror so I can avoid holding up motorists when passing parked cars or approaching blind corners, simply by timing my arrival to suit, easy with an electric.

Alternatively, if a pavement stretch is completely empty of pedestrians, I happily use pavement cutaways to pass parked cars on the pavement side to avoid holding up traffic in busy areas.

I always give priority to public transport whether riding or driving, often even when I have the right of way.

I slow to a crawl for horse riders in risky situations and wind down the window when driving to exchange greetings, always appreciated by the riders.

These are just some of many ways that I use the roads co-operatively, and in consequence often get a friendly toot or thank you wave from drivers. It's very noticeable how my local bus drivers go out of their way to be specifically helpful to me as a result. Many motorists are also helpful to cyclists, something all too easily ignored or forgotten by cyclists.

Just some of the thirty million road users doing the same could transform our roads, just by recognising that we are sharing a mutually difficult situation, not competing in it.

Summarising, I fall into every road users point of view.

don´t miss also this:
two german guys put two jet-cat rc-plane-turbine on the tail of a bike !
AND drive it in public traffic !

Jet Turbine Powered Bike - Google Video


and another video:
jet bike - Google Video
guys put a PULSA (pulsjet) on a small bike !
result is not that impressive
but the sound.. a video can never bring that sound to you PC...

life rc-planes with pulso on it can reach up to 400km/h speed !
and noice is unbelievable... over 140db can be reached !!!!!
