ZUKKA Bike Freewheel 6-Speed MF-TZ30,14-34 Teeth /7 -Speed MF-TZ500,14-28 Teeth Multiple Freewheel Threaded Hub Type Bike Accessories

Works very good with my derailleur and my bicycle.

Good range with very low gear.

First of all, this is a very good freewheel, simple, responsive, and functions just as it should. This is the 6-Speed MF-TZ30. It's a simple screw-on device but prepping with a good bicycle lubricant on the treads will make it easier to remove, using the proper tools; if servicing the bike requires it. Also, this unit doesn't require any add-ons, such that they would impede its' function on a tire; it is complete as is.Secondly, the customer service with this company is top-notch and very responsive to any concerns. I can attest to that fact when I had to contact them about it. For this product and this company, I can highly recommend both. Summary, this would be a good buy.

replacment looks good works good make shure you get spacers .

Worked perfectly for my el cheapo mountain bike from wal mart. Now I can pedal up steep hills when hunting. Beyond pleased

Makes hills so easy to go over. Makes for a great cargo/city bike.

This was a good replacement freewheel for my kid’s 24 inch trail bike. It was an easy install with the proper freewheel tool (also available from Amazon), and it runs smooth under power & during shifts.

Needed a longer chain and rear derailleur adjustment. But this allows these old knees to push this bike up the hills.Works great.
