Hi,

1.
Is this a correct installation of my tourqe arms? See my attached picture. I will have one on both sides even though the motor isn't that strong. I think I will put some rubber between the materials. Or should I change to a cable clamp like this instead:

On my cable installation kit I have a lot of cables joining into one in the front of the bike. There are some kind of "fix" that I don't understand what it is for. I have seen it on other coversion kits on the net too so I guess someone know what it is for? To attach to the bike on a nice way or what? See my second picture.

I have bought batterys from BMSB with including chargers. Can I just charge the batterys and then use it? There are a lot of topics about chargin in differens ways and measure cells and so on, but that doesn't apply to my who bought a ready package. Am I correct?

Torque arm install looks perfect to me.

The cables. Looks like some kind of bike has two holes that the wire can snap into. You could drill holes in your bike for that, but I'd just turn it so they face out, and use some zip ties to secure the wire. You could also cut the protrusions off for better looks.

The battery, plug it into the charger, until it turns green. I like to ease into use of new batteries. It might do nothing, but it eases my mind a lot. Charge fully, ride around the block, charge again. Repeat a few times, then leave the battery on the charger overnight.

I feel this helps the battery start out fully balanced, with all the cells as fully charged as possible. After that first overnight charge, then take the bike out for it's first really long, high speed ride.
 
Hi again,

There is no problem with the bike, but today I found this site about torque arms:
http://www.ebikes.ca/product-info/torque-arms.html

Under TorqArm_V1 it says "Notice that if the torque arm is mounted backwards, on the front side of the fork, then it would have the opposite effect and axle torque would tend to pop the wheel out of the dropout."

If this is true I have mounted them wrong? Maybe not a problem since I have two and its only 500W, but still...

Should I buy a TorqArm_V2 to be on safe side? (or maybe two)
 
Your torque arm installation is probably adequate. Personally, I don't like that arrangement because the torque is pushing the tie-bar along the fork, which is the worst direction. The solid torque arms (without screw) are better because the force on the fork is perpendicular to it.

The most important thing is that the first washer or nut, fits inside any dimple in the drop-out. It must not rest on the edge of the dimple.

OEMs use a special bracket to hold that cable manifold. It mounts on the steerer tube between the stem and the top of the steering head. It's just a flat plate with two holes that the manifold clips in to. You don't need it. The cables are always the wrong length anyway.

You don't have to do anything special with your chargers. Charge whenever you want. Don't run your battery right down if it isn't necessary.
 
If you didn't have the fender eyelets and bolts blocking it, it would be better to mount the TA going the other way.

It looked to me like you put them forward, because they fit poorly the other way.

And in any case, it's not like you have a 2000-3000w motor. So I think you are fine as you are.
