Perhaps a motor such as the one in the link below:
Just don’t know how reliable the SK8 ones are?
Any particular model of FOCBOX or are they all the same?
Makes sense to buy one VESC instead of two! I guess this works with my proposed motors and battery?
I have the 150kv version. Nice motor, but wide. Might be tough to fit duals in on a narrow truck.

80A in line fuse?
Don’t think I could put both motors next to each other with my trucks. Was planning to mount one like yours and the other on the underside of the board.
It’s doable, but close.

Yap the motors are the right ones. Maybe go with 149kV version.
I can’t speak out of personal experience, but from what I read here people had some issues in the beginning with the sk8 but lately they seem to be solid. Sk3 and sk8 are longer than the motor size point out, so have a look in the specs what’s the real length so that you can fit it on your trucks.
If you not fixed to hobbyking than maytech sealed and unsealed are a very good choice for solid motors. @okp sell the sealed version 6374 in 150kV or the 6355 in 190kV https://www.unikboards.com/en/boutique/moteur-skateboard-electrique-6374/ He might also have some focboxes left for sale.
Why 149KV instead of 190KV?
Does look good though. What KV rating are they?
If you go with the Flipsky dual 4.20 plus than 80a is more than enough. You can have a look on the data sheet in mouser. Those are slow blow fuses, I can’t say you exactly but the 80a fuse can handle 100-120a for more than 10s if I remember right. So that should be enough. I use the 100a on my mountain boards and that is pretty good there.
Lower kV is higher torque but less top speed.
These guys are in the UK I think. If I ever needed a crazy custom motor, they are the folks I’d buy from.
You are probably looking at 15 tooth motor pulleys and 32 tooth wheel pulleys. 80mm wheels are fairly small. These ratios are pretty close to what evolve uses.
I second @Andy87 note on both the kv rating and motor vendor. Unikboards is solid.
I got 149kv for a off-road build that never happened. 170kv is a nice balance.
I have a 200kv 4wd (6369) that still has enough torque to break 12mm belts if Starts are too aggressive.

Is a 170KV dual motor setup, Flipsky 4.20 dual and two turnigy 5000mah 5s 30C batteries in series an ideal configuration?
This is running a flipsky 4.20, smaller 5060 motors at 150kv motors (stock evolve) running at 40a battery max each (total 80amps from battery).
It is punchy and fun, but isn’t going to win any races, tops out around low 20s.
The battery is 10s5p li-ion cells. I’ve started using lipo on raceboards. They have been disappointing for distance riding.
The mechanics you are leaning toward seem reasonable/workable. What are your energy requirements? Are lipos new to you or are you an RC guy with the background?

Everything is new to me! I just want a board that is has a load of torque with a top speed of around 25mph. I’m using it to get to and from work. There are a few hills along the way so that’s where the torque comes in but who doesn’t like speed 
the sk8 6374’s are great motors. just a shame they’re so fucking long. dual sk3 6374’s will fit on tb218s but the sk8 ones will be a very very tight squeeze. with my mounts it wouldn’t fit so i used the FatBoy 230mm hangar instead. left me with a bit of leeway

That’s a nice setup, what gearing and size wheels do you have?
at the moment they’re 107s on 16/36 but I’ll be changing to 40t soon
Hi All,
Following your advice I put together a little schematic detailing component specs and configuration. Let me know what you think! What could be better and why?
Not sure whether to have 83mm or 110mm wheels? Done the ESK8 calculation and it seems the board won’t have a very high top speed but I assume it will have plenty of torque.
