Good write up on the New E Concept Scooter today in MCN. I was a Guide on the Launch in July when the Olympics started and Loved it . Instant Torque and good range , and that was a Concept bike . Looks like the future if a good network of charging sites can be set up

Gosh - it says that apparently you can 'trickle along at walking pace' on it!!!!! Wow!!! That's obviously utterly impossible on any other bike or scooter.....

:mrgreen:

Also you have to be a little careful in the wet in winter as there’s that much instant torque.

Tsk tsk. You both forget that is a MCN piece. :roll:

They are used to very fast bikes with zero torque at low revs/speed. I'm surprised they even know what Winter is....

:lol:

I guess this may be a serious point....after all, electric motors produce their max torque at zero speed (as I understand it), so I guess if you had a seriously powerful electric ptw, there must be a danger of losing traction at the traffic light drag race at times where road grip is reduced.

There again, there is always the on-board traction control.....when the tyre loses grip, we instinctively shut the throttle!!!

Yes to full torque at zero revs for a motor but:
On commercially bought electrics there is a controller box that determines how much current gets to the motor at a given speed. On a simple cheap one you can hear it cut in and out really quickly -making a humming noise.
They often have "jumper" switches to determine how much juice gets to the motor at lower speeds - if you are naughty and you know what you are doing you can easilly hot up the performance by changing the jumper slot. :twisted:
Top speed is sometimes set by these jumpers too icon_no_no.gif

On amateur builds the throttle is sometimes direct with no controller box - then you have to be careful - a handful of throttle means the bike is leaving without you

Yes, I enjoy them as well.....but I never buy anything from them. FAR too expensive!!
