mabman said:Hey Matthijs, where is that FS bike from? It is alot different than the stock Tonaro models. It has a name on the down tube but I can't make it out. It also looks like it has a front derailleur so if it does it has to be the Axle drive. And those videos give a much better explanation of how the Axle Drive works, thanks for that.
We'll get to the bottom of this yet Hillhater!
Matthijs said:That site was also posted by the ts. Would it be possible to run a higher power motor through these kind of bottom bracket kits? Or will there never be a high power bottom bracket system. I guess it is pretty hard to engineer a good piece of kit.

Yes, the ones fitted to dedicated Ebikes appear to drive the spindle direct ( ref ..diagram above)
.. but the pedalec "add on" unit shown in the video .. http://www.youtube.com/watch?v=I31YTrAprx4 .. clearly shows a short chain drive from the gearbox to the BBracket chainring.
both systems have their pro's and cons' depending on your needs.
But i still dont know if the "dedicated" spindle drive unit is available retail though ?

What are the pro's and con's comparing the 2 systems? Would a frame modification to fit the dedicated bb system outweigh the add-on version with the chain drive?

...We have been waiting for a kit version for more than a year. We were shown the latest prototype in October. Unfortunately, they are still not ready. We may have a sample included in our next order of bikes that will arrive in about six weeks....
....you can purchase the drive system from us. ...
....We stock all the parts including the motor, gearbox, freewheel crank and controller.

Hi Randall. Thanks for the info, but i am a little confused buy those statements ..would you clarify ?
The "Kit" you are waiting for is the "add on" unit that drives the existing bottom bracket via a short chain ?
You currently stock the drive unit with the "integrated " bottom bracket ?
Various articles refer to a 200w, a 350W , and even a 750W power rating. .. what is your understanding of power rating for these motors ?
Motor
High Torque 600
watt peak bracket
mount motor- 200
watt continuous

tried to order the 240W version, but they don't deliver to germany. I don't dare to call them, it was dificult enough to stumble through their french_only menus.
Anyone located in france, who wants to order for me and send it to germany?

<edit> Compared the data with the original chinese tonaro site: the french bikes are almost 10kg lighter ( I bet they are NOT )
>edit2> DOOOH, on the tonaro site, they list a number of dealers, including one in germany
