Let the competition begin. Considering the progress that zero had made I can't wait to see what a large company with fat pockets can accomplish. I think it was a brilliant move on Polaris.

Re: mongoose cx450 swing arm extension and brake mount

I may just make some dropout brackets myself then bolt and epoxy them to the swing arm . I just made a better template and I'm going to order some 6061 1/4" today. Once the swing arm is done I can make a motor bracket, paint everything and put it together. I'm planning on mounting the motor high so ...

Re: mongoose dirtbike (motard) swing extension and brake mou

Is there someone on the forums who modifies swing arms? I put a magnet to the swing arm and it was very magnetized to it. Does that rule out aluminum? I'm just mocking up what I started a couple years ago. I'm not sure if I'm going to use the components. http://i93.photobucket.com/albums/l42/duffman...

Re: mongoose blackcomb (lashout) My easiest project ever

Its a 8 tooth drive & 66 tooth driven. I bought 10 of the 8 tooth drive sprockets for like $30 shipped & the driven sprocket was from www.affordablegokarts.com/index.php plus it bolts direct to the disc mount $36. This motor barely gets hot. Its much different than the 750w motors. These 1000w motor...

I've had this idea for a while & it took a whole 3 hrs to make & assemble. Its funny how the simple low budget builds are the most effective.

Re: Construction of Electric Chopper

This is an amazing build. The amount of talent on this forum is amazing. I have blown 3 of those motors in the past & would not buy one again. This motor is the same mounting pattern but alot more powerful.
