I wish I had metal shop.
It is hard to take a new design idea to test having to pay someone else to do the cutting and and bending for a prototype, but if you are lucky like me you have a metal shop literally right around the corner.
I have really grown tired of customizing a front mount for most every bike because the motor mounts 'won't play nice' with the frame so I set out to make a mount that should fit most anything I ever build again, and I am starting with this existing direct drive bike someone else built and converting it to Jackshaft Shift Kit bike so the customer can use his 7-speed derailer gears.
Considering JS kits dual great motor mounts and 3rd 'height keeper' clap and shaft I could have just used what was laying around and use the existing frame hole bolt to secure it to hold the front...
But that is a frame hole mount and I hate those.
I would rater squeeze the frame a bit and use standard parts than compromise the frame by drilling a hole in it.
This first version will work dandy for this build, it just a custom 'L' bracket with a secure muffler clap to attach it to the frame on the side.
I will get to why that is important in a bit, but here are the test fit pics.
Note the grove to slide the motor up and down, important for a JS bike.
Nothing to it really, just a prefect fitting $1.50 muffler clamp and custom 'L' bracket. The rub with the bracket is not having the tools to do it yourself, that sucker cost me $35 to have made today!
It does the job though, and it doesn't get in the way on the left side of the bike where the tailpipe comes down and leaves space to get to most anything you want to adjust.
More tomorrow when I wrap this up, it's been a long day.
