Hi Electric Skateboard Fans,
I have finally created a welded motor mount that is usable with Paris Trucks. You simply, have to get them welded from a local aluminum welder which should cost $30-$40 for a pair of two trucks or less.
These welded motor mounts are for 63mm motors with a 32mm bolt spacing. They are made from 6061 Aluminum and 1/4" Thick. They are very sturdy and durable. I would highly recommend buying one or two for your Electric Skateboard build as they are very cheap at $35 for one shipped to the USA. Ready To Be Shipped, next business day.
