Hi, I've just tried the EM 5.7 at and around the factory, and I'm just amazed at the quality, the feeling of the bike... and its nice crew. It can be used from beginner to Expert, really versatile with its different maps. In 15 minutes I was at ease with the handling and controls. Within a...

From the beginning, it seems that KTM is keen on making their own engine cases, perhaps wanting to appear as a complete e-bike maker, not only part assembling, and thus are looking for different solutions from what's existing. Electric Motion (em5.7) chose to pick up from different manufacturer...

Motor is said to have 260-300v voltage, battery is 2,7kwh, that makes a 300v-10ah pack, what is the interest of so high a voltage compared to a 48v for exemple ?

Hey ! The controller software is pretty simple, but i'll wait until complete mounting be fore playong with Any parametre. Cheers

And here is the full electrical setup, It work for sure, but throttle control seems to be just on/off, I'll have to correct this. Perhaps it's because motor has no load ?

Just finished my battery case and harness ! Charging at 10 amps for a first attempt, seems to work fine, no heat at all. I have halved the pack so as to charge it as 2 separate 6s2p packs, in the end, the contact Key will do the halving of the pack (it is a battery connector as found on...

So many things to do ! Trial and error design, no adequate tooling (lathe...) need to wait for a lot of different parts... Today I have battery, motor, controller, throttle (magnificent set up by the way :wink: ), lot of sire to sold/connect, And I am waiting for my jackshaft, my skid plate...

Yep the jackshaft is the way to perfect this design !

Hi, I chose the Nissan leaf cell pack http://hybridautocenter.com/HAC4/index.php?option=com_content&view=article&id=72&Itemid=631

Here is a little update : Battery box completed, controler holder on the way : Should weight around 80 kg, 5kw motor, 48v60ah battery... And still learning aluminium welding !

With this corrected frame, Adam, you've addressed what would have refrained me from buying it in the first place. I mean gusseting seems now right, ball bearings for swing arm, excellent ! What about the swing arm, I'm sure you can even save weight on it. Xavier

Well e-Motion claims it's 2014 models are homologated ... Price tag is reaching reasonable level, are we at least there ?

Thx John, I thought these weren't compresses in the Leaf setup. I think I'll make compression plates part of the battery box structure as stiffeners. I should begin designing it tomorrow.

Thanks mvly, that´s precise ! Just ordered a powerful rc charger, as a full noob , I had nothing decent for charging, and didn't want to buy a too specialised charger.

Thanks for your answers ! These are new cells, supposed to be unused ( By the way : Any precautions to be taken with new packs ?), and they are particularly well suited for my use, as I needed Big capacity on a motorbike conversion. I read the previous thread where you've shown your setup...
