A tensioner with style and functionality

Hello from Lansing Michigan,
This is a tensioner that I made for my very first MB build, I wanted nice tensioner on a low budget, solid and beautiful, I finally got to use my degrees in art. I added an led light to add to the appeal.

Skull and cross bones, eh? Pretty cool.
I had to find a shape that would lend itself to the task, then it dawned on me that the crossbones would not only hinge down but also work great with the skateboard wheel from there the design fell into place. Do you think it would sell?
 
Very creative, and that blue back light was clever.

Do you think it would sell?
Sure a couple a year anyway.

The problem I see with that design, is needing to take the whole tensioner off to get to the engine covers.
How is mounted?
 
It's mounted by the bolts that appear as horns, they also are the bolts that hold that cover so it's really no extra work to get to the sprocket behind it , I did think about that in advance so it's no problem.
 
Cool!
If you need to get to the back cover you have to take them out anyway.

What concerns me is using skinny cover size bolts to hold up a piece of steel and be a chain tensioner too.
 
I don't remember them being all that "skinny", I always replace all the bolts and with a better quality maybe that's why I wasn't concerned at all, my only concern was how sharp I made the horns, I had some painful scratches by fall.

Heheheh...

Probably not as bad as riding something these these..

Anyway cool and I wish you luck.
 
Not to crazy about the look, there are skulls everywhere now, and I'm not sure why. But we do need a quality failure proof tensioner, one several times stronger than what is absolutely necessary, and that does not clamp onto any part of the bikes frame. Ideally the bike frame would have a super heavy duty steel mount welded on, and the tensioner would bolt to that. It would need to be adjustable, like a derailleur, so it could be lined up perfectly with the chain. And it would need to be under constant spring tension, so it would move with the tight and loose spots in the chain, keeping constant tension on it. I would like to see a steel sprocket, that fit the chain, running on high quality bearings. The basic design of a derailleur would seem close to what is needed, just bigger and much stronger, for the motor driven chain. Such a device is certainly possible, most would object to it's cost, but having almost been killed by one of those Chinese POS things (crashed inches from 45 mph traffic) I would not. Motorized bikes have long needed much higher quality components. Parts that fit without cutting and drilling and shimming, basically rigging things to try and make them fit the bike. I don't know of any statistics on the matter, but I have to wonder how many people have been killed or seriously injured when they rigged a Chinese engine kit to a Walmart bike with cheap wheels and only a rear coaster brake.

Sorry you're not crazy about the look, other than that it seems to be everything you're describing in your rant, stronger than necessary( do you see the size of that spring?) High quality bearings ( have you ever priced skateboard bearings?) With the skateboard wheel being 1.5" in depth it lines up perfectly with the chain is under constant tension with no cutting drilling or shimming needed, similar to a derailleur and doesn't hook to the frame, but if it's the skull that you really have a problem with you're not alone, my wife said that it wasn't for her either so maybe you'll like this design better,
