How much extra would it be to order a cromotor 2 with temp sensor with the toque raptor frame?

This is an AWESOME Idea. For people that want to run the Cromo on a Raptor, Torques and Raptor would no doubt figure out the perfect swingarm width and brake tabs for alignment.

it's aliveeeee!!!! i took it up to 60mph!!!! i feel way more comfortable goin at that speed with this frame now. Pedaling is fine, my knees rub against the seat post mount (blue portion) but not in an inhibitory way. I am too short for this frame! i have the seat set to the lowest point and i can't get my feet on the ground. Additionally, the other problem i see is how low the crank arm goes/how close to the ground it gets. If I'm making a sharp turn i will def hit the ground with my pedals. Not too excited about that. I might have to get shorter crank arms. I just bought the truvativ hussefelt arms. One of the pics shows how much clearance there is. I'm not sure if i can even go with a 24" ish wheel now.
However, when i was riding, got A LOT OF LOOKS. People were rolling their windows down and asking me what the hell i was riding and how i was pedaling at 45mph.
I need to get a better harness for my batteries because the wires themselves are taking up an incredible amount of room. I wish i had a pic of it...but the only one i have was from my previous build.....

Moonshine, why do you think you are having issues with potential pedal strike? My cross country bike pedals are even lower than yours and I have 175 mm crank arms, however I do not have as much suspension travel and sag will probably be less.
Does it have to do with sag? Is your rear shock spring not heavy enough so you are way low into your sag when riding?
The bottom bracket is a standard 83mm width, as long as the bottom bracket is up high enough and your sag is set correctly I see no reason why you should worry about pedal strikes on this bike more than any other. I do know that most down hill riders do use shorter 165mm cranks, but 165 vs 175 is less than a half inch of clearance.
Do you have any reason why you think that the bike is more susceptible to pedal strikes than your other bikes?
Could you measure your bottom bracket with no weight on the bike?
Edit: Looking more closely at your pedal setup I think you may have a very wide Q factor. First, your starting out with a wide 83mm bottom bracket, then your bottom bracket cups seem to be very wide (wider than a hollowtech 2 bottom bracket), your crank arms also seem to flare out. I wonder if your problem is not only long cranks, but also very wide cranks which cause your pedals to stick out really wide and strike more easily.

first one alive i guess 
how tall are you?
I believe the blue seat mount could / should be easily redesigned - make them slimmer to eliminate the knee contact

did you give from torque frame simulate the strength of materials on rear torque arms...von mises stuffs...I don't know why, but having broken my axel in 3 pieces due to heavy torque, I find your light on materials, for which torque did you design it plz if you have a value ?

Moonshine, that came together realy nice. Don't worry about the bottom bracket height. Just don't pedal in the turns and keep the pedal on the inside of the turn up. My cranks don't have much more clearance than yours running the 17 on the rear. From the bottom of the Vboxx to the ground is 12.5 inches. Just remember to wheelie orver anything taller than a couple of inches just be safe.

Moonshine, good to see your bike coming together. Might get myself one of those Kelly KBL96251 controllers for my Cromotor. Did you need to make any changes to the wire configuration or did the colours match up.
Finally my Framekit arrived!
Got some quick nightshot from the first partial assembling.
The stand is to short (obvious), but its the angle of the mountingplate!?
Actually i would say going for 24" rear and 26" front will make more sense for my needs.
Motor is a HT3525 and the electrical system will be 88V 15-25AH (must think about it) Lipo.
Will start a Build/Documentation thread soon.

Hi.
Here's our outlook on the bike dimensions:
BB height on typical DH bike is around 340-350 mm. When designing Raptor we wanted to give as many options as possible. That is why there are three positions for the rear shock mounting on the frame. The second most important thing in regulating the final bike height is to choose the right spring. Because of the grater weight of performance ebikes we recommend a bit higher spring ratio compared to non-electric bikes. You'll find some guidelines on which spring rate to use here.
Regarding the Q factor: the main reason for 83mm BB and the wide pedal spacing is that the swingarm is very wide in the rear due to high power motors (dropouts 165mm). Large Q factor is a must because otherwise the pedals would hit the swingarm, which is also wide in the front because of the fat tyre option. But 83mm BB is a standard for DH. There is also 100mm BB available.
About the crank arms – Monshine, I would suggest 165mm, you have so much electric power that a few more Watts of your leg power is insignificant compared to your power setup. All DH bikes have short cranks – due to flexing and also cornering.
Regarding the seat height – I can see that your seat is very high (if you measure it from the top sitting surface to the clamp on the seat post). Maybe you could try different seat and 165 mm cranks? Maybe that would ease your difficulties with pedaling as well.
If you were to use moto seat you would be sitting some 30-40mm lower. One of key advantages of the moto seat is when riding at high speed you can »grab« your bike with your legs (similar as on motorcycle). This gives you more control over the bike – especially at your 60mph speed

35kg total weight of the bike - that is impressive. I was thinking this beast would be much heavier and excluded it from my list of off-road ebike frames. But the battery is VERY small 48v16ah only..

How tall is Moonshine?
Yellow fork would be nice, but this used one makes it too.
I made a testdrive yesterday (without electrical) and the rear tire is slightly to big! It touches the swingarm very very gentle.
Tire is at 2Bar so i decide for now to let them make this out each other :x
I apologize the crappy inhouse pictures, but its raining like hell these days!

Da-Ben, where exactly does it touch the swingarm? The swingarm should fit up to a 10cm tire. Could you take a closeup picture of where it touches the swingarm?
Maybe you have the rim dished to one side or it is not true? Possibly you are hitting the very top of the swingarm and it is wide enough but not long enough?
Here is a quote below from torque bikes saying it can fit up to a 3" tire. Your Muddy Mary tires max size are a 2.5"
