MMMotors/Edinburgh Trike Services disc brake conversion.

Was browsing the 'net & checked out Edinburgh Trike Service's site.
The owners, Lil Miss PMT & Mark, were forum members here for a while. Seems they're now selling our Reliant rear disc brake conversion, as featured in issue 44 of 100% Biker over 4 years ago & reproduced here:

How do you feel about this?
I know you graciously posted it on the web for the benefit of every and any one, but it is still pretty much your idea. Is there any mention of thanks to MM for the inspiration, or better yet % sales commission

[BikerGran]

It's a cheek but if there's no patent it's legal.  Hardly surprising they're not posting here any more, tho!

[Terrortubby]

Cheeky swines!!

I'm not going to slate the Trike Services guys here -fair enough, they spotted a marketable product & went for it. Brock kept telling me I should've marketed it myself but, as usual, I wasn't organised -or bothered, enough to do it. Plenty of ideas get copied or adapted in the custom world.
Perhaps would've been nice if they'd just emailed me to tell me they were using my design though. 

[kustom]

yes i agree it wouldnt of hurt them to send you an email letting you know

[BikerGran]

Why not contact them and ask them to credit you with the design - it wouldn't cost them anything but it make them feel a bit guilty!

[brock]

     and here I was, biting my tounge. Have you worked out their margin yet ? allways room for competition and you have a much more visable profile with regard to advertising.  

[Firery Fred]

Well said Brock,I know where I'd rather get mine from

[Manky Monkey]

I'm really not too worried by it all. I perfected the design, which was basically just a matter of finding standard car components that would work together & making an adaptor plate, then put it out in the public domain for anyone to use -a public service thing.
I know of a dozen or so people who've used this set-up since the article appeared in 100% Biker, including another semi pro builder who's put together 4 or 5 of them. No problem, happy to be of help to fellow builders. Edinburgh Trike Services may well tell their customers it's based on the MMMotors design, I don't know.
Yes, I'm slightly miffed, but no more than that.
As regards profit margins, the discs are about 20 quid a pair, calipers are 20 quid each from scrapyards or 60 -70 for reconditioned units, (you have to have an old one to exchange though), handbrake levers 5 - 10 quid from the scrappy, cables 20 quid each made to order by Speedy Cables ltd or cheaper if you can adapt standard Golf ones yourself. That leaves the cost of the material to make the adaptor plates, plus the machining costs unless you've got your own milling machine. SaddleBags made a couple of pairs for me in return for some trike parts. No idea what it'd cost to make them on a production basis, or just how many kits you'd sell. I'm happy to remain an enthusiastic ammateur builder I think.    

[lunatic]

Suppose when you think that all the parts would be new, non exchange items, there isnt a massive profit to be made really. But I think with the amount of trikes being built using reliant axles, plus the ones already out there, there is a market for them, but they wouldnt exactly fly out the door! Ok if you can afford to put a few kits together and have them sitting around waiting for customers.

[saddlebags]

300quid sounds a pretty good price to me,the kit does look good,as for using your design Manky if you put things on the net for all to see and its a good idea sooner or later some one will use that design and make money from it ,the best you hope for is the satisfaction that someone has considered your design good enough to copy and stake their own reputation on,after all imitation is the  sincerest form of flattery.

[Manky Monkey]

Precisely. 

[Nomad]

They are still ungratefull thieving twats tho in my opinion.

We all buy things at an inflated price due to development costs, and acknowledge that. They haven't had those costs.

The minimum they could have done is beg youre permission on the promise of a recognition statement.


HOWEVER.....I have given away many design ideas especially in the arena of safety critical kit, because of the risk of injury or death to those implementing them/and or their installation. The profit margin on these kits does not warrant the possible claim against loss on life.

BTW I have sent a mail asking where their inspiration came from.

if ya want my opinion?? their taking the piss! but it will bite them in the ass!!! if they used the origenal  drawing andy put in the mag?? they run the risk of a major mishap as the centre hole is large enough to let the halfshaft bearing pull through! which will result in the wheel coming away from the trike! without sounding harsh let them pay by their mistake!!!!
