The folks at BMW Motorrad have come up with an electric scooter concept called the E-Scooter, which offers a comparable performance to a conventional maxi scooter, but in much cleaner fashion
Conceived as a future-oriented vehicle for commuting between urban areas and the city centre, the E-Scooter provides the necessary sustained output and maximum speed for safe and reliable operation on urban motorways and when asked to carry two people.
While no output figures are provided, BMW says that the development study has the necessary juice to be able to achieve acceleration figures within the important 0-60 kph range, and this is at the level of current 600 cc maxi scooters.
The E-Scooter has an operational range of over 100 km, and its battery can be charged at regular household power sockets, so no special charging station is required. When completely flat, the charging period for the unit is less than three hours, with shorter charging times for batteries that aren’t completely out of juice, of course.
The charging device includes a charge cable, and in addition to other components like an ISO insulation monitor, high-voltage indicator and a high-voltage distributor, a DC/DC converter is included with the E-Scooter – it’s required to change high voltage to low voltage power for the 12V power supply and especially for the control units.
There’s no main frame with this one – the aluminium battery casing, which also contains the electronic system required for battery cell monitoring, takes over the function of the frame. The steering head support is connected to this, as is the rear frame as well as the left-hand mounted, single swing arm with a directly hinged, horizontally installed shock absorber.
The E-Scooter has no hub motor with direct drive or planetary gearbox – instead, the primary electric drive is mounted behind the battery casing, while the secondary drive is made up of a toothed belt from the electric machine to the belt, pulley-mounted coaxially on the swinging fork pivot with drive pinion. From here, power transmission occurs via a roller chain to the rear wheel.
There’s energy regeneration too, when the E-Scooter is decelerated in trailing throttle or when braking, and this offers between 10 and 20% increased range, depending on the driving profile.
During travel, the electric machine and power electronics are liquid-cooled, as is the charging device during charging. An electric coolant pump ensures coolant circulation through the radiator, though the battery on the E-Scooter features an air-cooled system, chosen to save space.
Looking to sell your car? Sell it with Carro.
I guess it will be more expensive than the RM4,888 for Modenas' CTric?

wah, high end bikes also going electric
This Is Best BROOO!!
Its same as Modenas Elegan.
gud to know there are efforts made to produce electrice vechiles..
we will need it

Damm u BMW motorrad, why can't u make gas powered scooter like other people?? Our electricity rate is going up soon.
the electric bill is already up!!
so is it really greener? since we still need to use the household electricity
or just bcos oil is getting less, and more expensive~
I want one!!!
This will definitely give Vectrix some serious competition.
I really hope this takes off – i believe in the electric products and that they have a bright future. I would love to try to sell these in the US – on my website. www.chargedelectricscooters.com. Thanks for the information.
nice body colour…
disagree, i think it's artwork is not exciting nor aesthetically appealing. Merely eye-catching without deeper meaning nor evoking beyond-norm emotions.
it's the typical BMW prototype sticker in case you don't know
this bike is in a way different legue bro.. nothing like ctric..
