File the holes in the middle to match up with the holes on the engine
I did not receive ANY bolts to mount this to my engine. I had to source my own. Please include 6mm and 8mm bolts for future sales. Also the holes in the middle that mount the plate to the engine needed to be filed farther apart. The hole is about 1-2mm short away from being prerfect. Aside from that this will work and is better than buying the single hoop version this size extremely durable

seems great
I like the idea of double u bolts and the slotted engine mount holes.

Some Motor Kits Don’t Match All Frames
Some motor kits only come with brackets that can fit smaller diameter bike frame tubing. This bracket allows the motors to mount on the larger frames.

Didn't fit large frame tube.
Did not fit Kent Bayside cruiser as stated in other review.Reason for not fitting design of mount plate is incorrect. The bolt's heads that mount motor to bracket hit frame before plate contacts frame ...so plate never rests flat against tube just against the heads of a bolt on each side making this SUPER DANGEROUS to use on larger tube frames. There is not enough distance between mount holes on the motor's crankcase to allow this mount plate to be used on large tube frames. The curvature in the mount plate is far to small for any frame over 1.625" diameter making it honestly almost pointless consider if it's 1.5" it fits into the mount on the crankcase and no need for a mount plate. 🤔Larger tube frames such as Kent Bayside, Glendale ect. ...are closer to 1.75"The ubolt hardware included is very lightweight and low quality.After trying every which way to use this mount it just sits in a box on my part shelf waiting for a "someday use".This mounting hardware would work well on some frames but nothing over 1.625" diameter frame tubes and nothing with a motor that has any real power or torque. It's basically the quality of the stock cheapy you get with a kit just a different design.As it turns out with a little thought and need I designed an awesome mount that can be manufactured/fabricated to fit any size diameter frame. 😉
