Jeremywell 10 Pieces #415 Offset Link 1/2 Link, Half Link, Crank Link, Motorized Bicycle

Doesn't fit 415H chain and it doesn't say it does exactly but it says motorized bicycle in the description.....it's for 415 without the H. The hole is smaller so your 415H master link won't fit. This will not fit stock motorized bike chain from China.

Its a 10 piece pack of disappointment delivered to your door. This is not a #415 half link. I suspect its a #410. The cotter pin side fits onto the chain very very tight. A 415 master link will not fit through the other end, nor will a regular #415 chain pin fit through the narrow side. Yes i am using it on a #415 chain. I measured with my calipers (which are not perfectly calibrated but they are consistent), the opening on a #415 link measured 0.159in (ID). The removed #415 pin measured 0.154in (OD). The opening in the half link measured 0.144in (ID) TO SMALL!!!. The master link pin measured 0.155in (OD). This will NOT work for a #415 chain.

Perfect

These do not fit #415 for Motorized Bicycles. I got 10 of 1/2 Links and i got 10 full Master links. and the masterlinks were right ones. but the 1/2 links would not fit my chain or the new links... Would recomend a new chain other than trying this. just did not work... the company would not reply to e-mails requesting return and had to contact amazon Support to send thelm back and get my credit back. So this is my problam.. and 2th the Cotter Key. is weak and not that good i would recomend replacing it.

I took a risk as I wanted to get my gas bike back on the rode quick so paid for same day. Sure enough, my 415 master link will not go through the hole. Buyer beware!

This does not fit a 415 motorized bicycle chain and it's cheap junk that breaks by just handling. Waste of time and money.

Won’t actually even work on my 415 chain. Hole diameter too small to accept a 415 Master, and material too thin to actually drill it out.

Thin plates smaller pins
