ZUKKABike Rear Derailleur RD-TY21/RD-TY200 with Hub Bolt 6/7 Speed Hanger Mount or Direct Mount for Mountain Bicycles

Absolutely fantastic deraileur, installed on my kids six speed Walmart bike and it shifts MUCH better than when bike came with new. Great to see that Shimano product is still good.

I like this derailleur it was a big upgrade for our hyper havoc bike from Walmart. The old one kept slipping gears and could never adjust. I replaced them both with this kind and it fit and changes gears perfectly

It fit well to the bike and working fine

Awesome quality and good price

Keeps e-bike running as expected

I replaced a Shimoo derailleur and was a little shy about doing the install thinking it would be a long ordeal. But it turned out to be a 10 min install and about 20 mins to adjust for the smooth gear changes.

There are no installation instructions provided. The barcode that comes with it stating it is the instructions is not, it is a data sheet. Once installed it is a major pain to adjust properly. The quality is ok, almost all plastic including the gears. It is low cost for a complicated assembly, but that is due to the materials used.

Shifter is exactly the same that came on my Huffy mountain bike. Fast shipping and a excellent price. I would recommend.
