Mounting a motor directly on to the deck

[spobward]

Hi guys,

I'm planning my first eboard build and have been reading through lots of posts, trying to get an idea of the best way to go about doing things (it seems like a great community you've got going here by the way). I'm trying to minimise both cost and size of parts. I'm hoping to convert this 24" board I've already got and planning to use as many of the existing parts as possible: http://www.amazon.co.uk/Osprey-Stripe-Mini-Cruiser-Multicoloured/dp/B009FUN7G0/ref=sr_1_7?ie=UTF8&qid=1387130997&sr=8-7&keywords=mini+cruiser

It seems like the first decision I have to make is how to mount the motor (I think I'm going for a single mount as from what I've read this provides more than enough power/torque). All of the builds I've come across have the motor mounted directly on the trucks. I'm not able to weld this myself and so I thought it might be easier and cheaper to mount the motor directly to the deck. Is there any reason why this wouldn't work?

Hi...
I might be wrong but I am afraid the distance between the deck and the Wheel axle may vary when the board is being used ? I am not sure if an elastic belt would eventually exists to compensiate the changes of this distance

or, you could make a 3 Wheel board with a stiff transmission on one Wheel, and the 2 others for steering...

Ah I see. I guess the drive belt may snap when the deck flexes? Has anyone actually tried doing this?

Look how your a skateboard works,
it's not only the flex of the deck which matters, it's the tilting of the truck...
(I am afraid the ones who tried will be a bit shy to talk about it)

Good point, thanks.

It looks like I'm going to have to splash out on some pre-welded trucks.

Well, if you use a transaxle truck like this, it shall be possible.
