Being able to adjust both the pulley and the bracket is extremely useful.

Dont waste your time or life with the bolt on tensioner that comes in the China Doll kits. This is safer and easy to adjust your chain. This is possibly the best common sense upgrade you can add. I highly recommend this and your family will to!

Good producct I installed it and have only rode a few times since i got it but everything seems sturdy i had to switch the little wheels to other side of the bracket because they seemed to be on backwards but it was no big deal it took 2 seconds to fix it

If you are going to get a gas powered motor for your bicycle this is a musy have item. Its a real pain in the butt to align your chain but this product works perfectly.. Thanks for a great product!!!

I have built numerous motorized bikes as a hobby and found this a very useful way to maintain chain tension to custom built and certain model bikes. I find the quality fading off purchasing the silver model as my 2nd one purchased. I like that the arch type chain tensioner gives more options for mounting to maintain chain alignment.I dislike that this is the 2nd. one I've purchased, the 1st being black and seems much sturdier than the silver option that was the 2nd I purchased based on how good the black one I ordered the 1st time was. Sadly the silver one is not the same quality.Regardless it works as it should just wish it was tougher like the 1st one I received and I feel like quality and sturdiness of the silver option just isn't the same. When compared to the black model even the idler wheels are not the same quality as the 1st one purchased is. Not sure why this is true but fading quality leaves me hesitant for future purchases. Maybe look to see if there's a different seller who maintains consistent quality.
