BlueSunshine Front and Back Disk Brake Kit - 160mm For 80cc Gas Motorized Bicycle - Freewheel Threaded Hubs Hole distance of 48mm

The brakes were a bolt on for our MX650 with out the extra ring on the discs. The brake handles are garbage. The left one broke in my 12 year old sons hand on the second ride. He did not crash, he did not fall over, but when he pulled on the brakes, the silver pull snapped.

good item

Lil hard to hook up but overall works good

Replaced my brakes on my electric bike so far so good

It was a heck of a time getting the adapter off i had to shave the bolt heads down. Only to find that i need a diffrent/ smaller bolt separation i got the 44cm but i need the 42cm. Not the sellers fault, so when i get a chance im going to get the size i need from this same seller

just like the other reviewers i shoulda listen to... so here i m all these packages unpacked, tools scattered about, just got back from having a mechanic break loose the 2 bolts on the 2 of the rotors cuze they were torqued on so tight .... and they're the WRONG bolt hole pattern..!I realize they prob don't speak english ~ but dont they speak the SAME language so they can match bolt hole patterns...? OBVIOUSLY not or maybe the bolts would line up... but why advertise the (supposedly) mateing parts on the same page if the don't go together? Whatever - gonna spend the rest of the evening repackaging to return, cleaning up my workspace and putting aside the 1/2 finished conversion to mag wheels an disk brakes on my motorized bike and wait and RE-research who might have the right sizes ~ THAT match ~ then reorder and reassemble the mess that WAS my motorized transport. These disk brakes do NOT directly bolt onto the 10 spoke "star" pattern "motorized bike mag wheel" assemblies as claimed. Someone should be sued for false advertising and wastiing alot of peoples time. they probably won't even post this ~ although ive spent 100's of dollars on amazon ~ this is my 1st review and im extremely unhappy...! i got better things to do than write negative reviews and having to file law suits.save yourself the headache ~ im not sure yet what the correct path i'll have to choose to get A to fit to B to fit to C but its not rocket science.... although makes me wonder who theyve got in their R&D dept... obviously nobody that gives a &(^%.... good luck ~ measure twice / cut once ~ someone needs to go back to school

As advertised

2 stars because although they work pretty well, they came damaged and all scratched up. There was absolutely zero packing material to keep the calipers from rubbing on the rotors resulting in a really trashy look like they were used on arrival. The bolts used for the rotor are also of low quality. I'd recommend replacing those with high torque metric bolts. Also the rotors are pretty thin. Actually thinner than my stock rotors. Hopefully this is a weight reduction bonus, and not a performance reduction/warping over less time. I will update later after using them for a bit of time.
