Source for dual motor mount to fit MBS Matrix trucks?

[mjp8081]

As far as I can tell, most people are making them at home, but there is a lot of talk about wanting them on the forum.

Does anyone out there make and sell these at a decent price, at this time?

Is the lack of them because most people use a sturdier/better type of trucks?

I just thought MBS Matrix is an easy solution because theres tons of them out there, and it happens to be what I already have a few of. But if there is a preferred truck to use and it's affordable or worth it I'd love to know about it.

Thanks all!

There aren't much motor mounts for MBS trucks atm. A few people have had batchs a while back but I don't think they frequent the forums as much now.

If you're not overly concerned about the weight, you could bolt on a plate to the bottom of the Matrix truck. Then you can put L-brackets to mount your motors on to.

I do want to keep the weight down, to get some minimal air occasionally. Yeah, I would love to have some minimalistic aluminum brackets. Did you use the brake mounting holes at all, or were those to small? I know from experience with my 50cc gas board years ago how important solid motor mounts are to control the torque pull and keep the chain and everything straight and aligned.

I am also trying to source mounts. Just dont have the time to fab them.

Are you guys trying to source weld-on or bolt/clamp on mounts?

Myself, I'm looking for clamp/bolt-on, preferably aluminum.

 

[NJEV]

Same here. Bolt on or clamp of sorts is what I need.

 

[777arc]

Yeah if someone made a bolt-on that fit the MBS ATS trucks I would buy it. Although because it does not exist, and weld-on ones are common, it might be cheaper to just ship your trucks to someone who makes the weld-on and get them to weld it and ship it back.

 

[torqueboards]

Which trucks do you guys have? MBS Pro Matrix?

 

[NJEV]

Mbs matrix. Have a new set of matrix otw.

Is there someone you know or recommend?

guys, its really easy.

Get a 1/8 aluminum plate, drill a BIG hole in the middle to make it lighter. Then look at the bottom of your Matrix, see those holes there, use them to bolt the plate on. You can even drill a bigger hole in the middle, just make sure you don't hit the bridge where the kingpin bolt goes through. You now have a plate where you can mount the brackets to hold the motors! I've been using this design with two heavy brushed motors and they hold up pretty well.

Do not be afraid of a little weight. Weight is needed for a comfy ride, especially if you plan to go off-road. A lot of people here started with small wheels, 6s or less batteries and teeny-weenie motors just so that they can brag that their boards weight next to nothing.
A lot of them have now moved on to bigger wheels, 8s/10s/12s! and 63mm motors. Don't be concerned how it looks too, that's the easiest part and can be fixed later. This is a DIY forum after all.

Hey Guys,

I know that Torque is working on a design for the MBS trucks and if he has one in the works its likely worth waiting for. Its always great to support a local member of ES and while i have yet to buy anything from him myself, we have exchanged emails quite a bit and he is a genuine honest guy. When i did inquire about buying something he steered me away form his item I was looking for as it did not fully meet my needs. Rather than just make a sale, he sees the big picture in trying to help people in getting into eboards.

Just my $.02

 

[torqueboards]

Hold on.. lol I might not having something for MBS trucks at the moment. But thanks.

I ride around 10 miles a day during a hard urban commute weather permiting atm. I also offroad a lot when ever I can. I started with a metal plate that I drilled out. I moved to angle aluminum. I had a hard time getting the rear truck off the ground when popping for debri, potholes and curbs. It is possilbe atm but just barely. My rear truck is going to eat it almost every time. Between me and my gear the board is holding some 275 pounts easily. Every pound counts for me as my board is taking a beating every day. Pluss I want to move to 2 motors this summer as I am currently using a single brushed atm. Good brackets are a major upgrade for me and would make my daily rider that much better.

I think people approach this the wrong way. The focuse should be on getting something aluminum that mounts on the truck. Just an platform that we can interface with. This would give us the ability to take it from there. That is the hardest part to machine for most DIYers. Motors mounts are great but honestly my endgame is 4 wheel disc brakes on my mbs and I belive that would not be hard to do on the cheep with the gear available today. Honestly the one thing holding my board back is RC tech. If I had a reliable mechanical brake system I could run real EV quality controllers but right now I am stuck with the electric brake

MBS makes a brake system for their trucks. it could be adapted to work with a servo instead of the hand lever. Its not a disc, but its better then regen braking.

I get what you're saying, the board I have now uses a non-outrunner (or inrunner I guess) motor like yours that mounts like that, a flat sheet mounted flush with the bottom of the truck. With the outrunners you have to go with a vertically oriented plate. But I may have to do it exactly like you say, and bolt something on to the horizontal plate to get the the right angle/vertical to mount the motor to.

 

[mjp8081]

After going to a couple plate aluminum metal suppliers online and being shocked by the prices, I happened upon eBay--turns out a GREAT source for plate aluminum at low price.

 

[LEVer]

mjp8081, you can mount both inrunner and outrunner motors, just make sure your horizontal bars do not hit the motors. Watch out for eddy currents from the horizontal bar when you use outrunners. If you can find a sturdy plastic bar, use that instead of the metal.

BTW, i said 1/8 aluminum plate because I thought you were going to use light motors. If your motors are heavy like mine, you better use 1/4 aluminum plates.

I have the mbs brakes. They suck hard. Wear fast. Need constant adjustment. bad design but fine for mountain boarding.

Kind a like this:

Pediglide, nice setup. Can you take a picture of the bottom of the mount and show how you attached it to the truck? I think I'm gonna make my own like how you described. Does all the metal plate under both the motors cause any issues with eddy currents? thanks!

 

[onloop]

I've included a new feature on the 2015 edition enertion motor mounts that might solve this problem. The new design has some additional holes drilled & tapped that run perpendicular to the truck hanger. This can be used to bite into a random shaped truck hanger and prevent rotation due to torque forces.

The idea is that you can use the clamp strength of the mount to hold onto the hanger. But nothing will stop it rotating. But now you clamp up, then screw in the M4 set screws to prevent rotation.

You can see it on this picture. Open image in new window ias it might be cut off.

I offer free shipping and also you can return the item within 300 days for a full refund If it does not work.

The small bolts thread into the spring plastic caps of the matrix truck. For the big bolt, I drilled a hole in the middle and used lock nuts. Be careful not to hit the kingpin bridge when you drill. The holes on the sides close to the wheels are where the bolts for the motor mount goes.

If you're going to do a lot of off-road, I would recommend flat-head bolts and counter-sunk holes so that your bolt heads don't get scraped. I'd drill big holes on the plate to make it lighter too.

I really don't think the plate causes any eddy current issues but the horizontal bars maybe. You can use brass or copper tube to insulate the threaded bar inside.

 

[kwoolf1]

Thanks Pediglide. Is that 3/8" aluminium plate? How wide of a piece of stock should I order? Will 8" x 8" be sufficient?

Also, the "L" brackets for the motor mounts, did you go with 1/8" thick aluminum?
