I think some of you guys need to chill. I pretty sure that the first incarnation of the mount insert was by RS4Race.
In fact in the very next post torqueboards compliments him on his design.
As to the two part adjustable tension design, that is Alien Drives design as far as I can tell. It was an evolution of the previous design to increase the mount strength
As to cheaper prices, it just means that the suppliers are in Asia.
I find that a few of the DIY estakeboard suppliers focus too much on price. I’ve has a couple of them contact me about supplying electronics modules. In the end it comes down to my prices being too high. It astounds me that they expect me to compete with Asian sweat shops.
In fact, I had one of the popular DIY eskateboard component sellers commited to purchase to a batch of miniwiicever boards at a quoted price. Then when I informed them that they were ready to ship I get this reply;
“Dropping prices on a lot of stuff though and usually customers will buy the wiiceiver as well.
***How many do you have? How much each? I can try and sell them if you want to get rid of them.***”
Then a few months later I get a followup asking at what price I can supply them for now.
In the end I realized that it wasn’t worth dealing with these people.
The comments about who was first to use a particular design are unhelpful.
Alien Designs were the first to sell bolt on mounts, DIY Electric the first to sell weld on mounts. That does not mean that no one else can make weld on or bold on mounts. The exception would be a blueprint copy and I don’t see that anywhere.
When I made my own motor mounts, I looked at what was around and used the best ideas of what I saw. On a feature that was my own design, a bar to protect the motors and strengthen the mounts and a block to protect the wheel pulley, one of the suppliers indicated that I copied his design. A design that I hadn’t seen until he made the comment.
In the end, almost all designs are an iteration on a previous design(s). You should feel flattered that your contribution has added to the improvement of the design of motor mounts.
After all, this is a DIY electric skateboard forum.
