Do you have a front brake also?........Curt

I have a 203mm front disc brake that can stop it pretty good.

Not entirely finished yet, rode for the second time in 2 days, did 10 miles this time.

I bought my cranbrook at walmart last year, when i was there today i noticed that the frames have changed on the cranbrooks they have on the floor, seat tube has a back bend a couple of inches above the bottom bracket, maybe more room for motor? and i thought the tubing look like a bigger diameter?

About your 3/8” motor mount plat, did you slot it to slide the motor? Or sideways slots?........Curt

 

[willis617]

I made the motor mount last year so i don't remember which part of the mounting system got the slots, but yes there are slots for forward and back adjustments, there is also some side clearance to match up chain drive lines.
I do remember that the threaded mounting hole locations on the motors bottom were off location from the manual specs, 1 or 2mm i recall.

 

[willis617]

I could remove one of the bolts and let you know which component i slotted if it helps?

 

[curtisfox]

That’s ok, I can figure it out, cool idea,like your build.......Curt

 

[willis617]

After thinking about it, the slots are in the .25" alum angle, if they had been in motor plate it would of had to been made longer to allow clearance for fasteners next to engine block throughout adjustment range.

THANK YOU! Was thinking something like that, KOOL......Curt

Nice work. I like the mounting plate/bracket design. Did you shape it by hand or CNC? It looks so good I can’t tell.
