Interesting... selling just the motor and controller (plus accessories) seems like a smart call for them. Less convenient if you are buying from them, but this is a great setup for a project bike. The limited power, but sweet aircooled motor would make a really nice vintage bike build. I wonder if @AltaWest could do something like this.

That's a neat motor, thanks for the tag Jon and sharing the link gesel. Not an Alta, but a great DIY alternative that's decent looking. We still have some Sony's left, so you could build an Alta pack for one.

I went to their website and clicked on ebock_1. This came up and I used google translator to translate the information. Impressive. 30KW from a 36 volt set up. I guess the phase wires are as big as dimes in diameter.

Across Germany, more and more motocross tracks are being closed due to environmental and noise issues. A new construction of conventional moto-cross tracks is practically almost impossible in Germany. With the electrically powered motocross motorcycle ebook, all editions are fulfilled without further ado and thus the construction of new and modern race tracks is made possible.

The eBock is an electrically powered motocross motorcycle, equipped with state-of-the-art high-end components of electrical and racing technology.

The patented 36V quick-change battery system in conjunction with the most efficient and high-performance synchronous motor, enables the permanent, with all the senses experienced moto-cross use in the performance range of a conventional 250cc engine (30kW).

Due to the completely dry, stepless, quiet and high-torque drive, the previous limits of the doable can be expanded.

Maintenance work such as oil, filter and piston changes are a thing of the past. The electric drive strand is 350 hours maintenance-free.

The rear wheel brake is a wear-free, pure recovery brake and can be operated with either the left hand or the right foot at the customer's request. Is braked with the foot, can be optionally electrically coupled in the left hand.

Up to 8 mappings can be selected via a mapping switch. Not only the performance development, but also the engine brake can be switched on or off at the desired strength.

The capacity of the battery is sufficient for a good amateur driver for 30 min moto-cross deployment. With the standard charger, the battery can be fully charged in 1 hour. Optionally, a fast charger can also be purchased, which allows the battery to be recharged to 100% in 30 minutes. The battery can be charged more than 1000 times without loss of capacity, even with the permanent use of the fast charger.

Its centric mass concentration gives the eBock a perfect focal point, allowing it to playfully control and move playfully, whether in the air or on the floor.

After driving, the eBock can be cleaned with the steam emitter as usual. Water as a match is also no problem during the ride.

All components from the most diverse technical disciplines are matched to an incomparable interplay and can be customized.

At the latest after the first ride, it's clear what the eBock looks like and what it was made for; to be able to experience motocross with all the senses.





"It's time to rethink its usual perceptions and expand its own boundaries through the now-useful benefits."

Soooo... my math tells me to get 30KW from a 36volt system, DC amps have to be around 833amps. :eek: Its approximate. I am guessing if its 36 volt system using 18650 cells, probably looking at 10S 40P or maybe even 50P, if the pack is as big as the Alta. who knows. I can't find any other info on it.

I like the idea, to have a regenerative brake on the rear in combination with the rearbrakelever! There is no brakedisc anymore!
Because regen braking is usually the result of the current going back into the controller and to the battery, I am guessing that they are regualting the amps and probably have things turned up enough that the rear wheel can be locked up on any surface. With the amount of DC amps flowing through the system, it would probably only take 400 or 500 of the 800 plus available amps from braking to lock the rear wheel up completely. I am just guessing on this. Years ago, I built an 11kw ebike with an Adaptto controller, I could program regen amps from the on board computer to do what ever I wanted it to do, as long as I stayed with in the confines of the systems limitations.

It's a 72v system. Check out the image from the front page:

1596122008582.png

The image next to this one on that page also shows a 48v version that is limited to 20kW.

Also, it does not appear that they are selling a bike or battery, just "drive-train components" and tires.

If anyone wants to know more, I'm fluent in German and would be happy to breakdown any of the details. I was reading the site initally and didn't stop to consider that I might need to translate... opps!

Hey John, thats awesome!!! Here is what I used the google translator to translate

Deutschlandweit werden immer mehr Moto-Cross Strecken aufgrund von Umwelt- und Lärm Auflagen geschlossen. Ein Neubau von konventionellen Moto-Cross Strecken ist in Deutschland praktisch kaum bis unmöglich. Mit dem elektrisch angetriebenen Motocross Motorrad eBock werden alle Auflagen ohne weiteres erfüllt und dadurch den Bau von neuen und Modernen Rennstrecken ermöglicht.
Der eBock ist ein elektrisch angetriebenes Motocross Motorrad, ausgerüstet mit modernsten High End Komponenten der Elektro- und Rennsporttechnik.
Das patentierte 36V Schnellwechsel-Akkusystem in Verbindung mit dem höchst effizienten und leistungsdichten Synchronmotor, ermöglicht den permanenten, mit allen Sinnen zu erlebenden Moto-Cross Einsatz im Leistungsbereich einer konventionellen 250ccm Maschine (30kW).
Durch den komplett trockenen, stufenlosen, leisen und drehmomentstarken Antrieb lassen sich die bisherigen Grenzen des Machbaren ausweiten.
Wartungsarbeiten wie Öl-, Filter- und Kolbenwechsel gehören der Vergangenheit an. Der elektrische Antriebsstrang ist 350h wartungsfrei.
Die Hinterradbremse ist eine verschleißfreie, reine Recouperationsbremse und kann auf Kundenwunsch entweder mit der linken Hand oder dem rechten Fuß bedient werden. Wird mit dem Fuß gebremst, kann an der linken Hand optional elektrisch gekuppelt werden.
Über einen Mappingschalter können bis zu 8 Mappings gewählt werden. Über die verschiedenen Mappings kann nicht nur die Leistungsentfaltung, sondern auch die Motorbremse in der gewünschten Stärke zu, oder abgeschaltet werden.
Die Kapazität des Akkus reicht bei einem guten Amateur Fahrer für 30 min Moto- Cross Einsatz. Mit dem Standard- Ladegerät kann der Akku in 1h vollgeladen werden. Optional kann auch ein Schnell- Ladegerät erworben werden, das es ermöglicht den Akku in 30 min wieder auf 100% zu laden. Der Akku kann mehr als 1000-mal ohne Kapazitätsverlust geladen werden, auch bei dauerhaftem Einsatz des Schnell- Ladegerätes.
Seine zentrische Massenkonzentration verleiht dem eBock einen perfekten Schwerpunkt, wodurch er sich egal ob in der Luft oder auf dem Boden spielerisch leicht kontrollieren und bewegen lässt.
Nach dem Fahreinsatz kann der eBock wie gewohnt mit dem Dampfstrahler gereinigt werden. Auch während der Fahrt ist Wasser als auch Matsch kein Problem.
Alle Komponenten aus den unterschiedlichsten technischen Disziplinen sind zu einem unvergleichlichen Zusammenspiel abgestimmt und können kundenspezifisch angepasst werden.
Spätestens nach der ersten Fahrt ist klar, was den eBock ausmacht und wofür er gemacht wurde; um Motocross mit allen Sinnen erleben zu können.


„Es ist an der Zeit, seine gewohnten Vorstellungen zu überdenken und durch die nun nutzbaren Vorteile, die eigenen Grenzen auszuweiten.“
