Shimano MF-TZ31-7 Speed MTB Bicycle Bike Cassette Freewheel Screw-On 14-34T

Like only having 1 to 5.5 speeds.

Anybody try this yet.?


The RadCity 5 + has a 11-34T and 11-13-15-18-21-24-34 front is single ratio of 46T


Anybody find anything other than the OEM unit that is still 11-34T. ?

I had to replace the freewheel on my wife's RadCity 5+ because I plopped the whole thing in an ultrasonic to clean it and I wound up flushing out all of the lubricant... my bad... couldn't figure out how to disassemble it to re-grease it... I couldn't get enough oil into it to free up a pawl (I think) that got stuck... anyway... I went with a DnP 34T which is the stock freewheel that came with the bike.  Got it on Amazon (https://amzn.to/3V5zqWP).  Worked great this past week on an long trail ride for her.  Was around $35.

What tool did you use to remove freewheel?  I'm looking at the park tool fr-1.3 (https://amzn.to/3SVfTGX) but not sure if it is the right tool

gooberff, if the motor your trying to remove the free wheel from, has the motor electrical wiring coming out of the end of the axle shaft the park tool won't work. The best option is to order a tool from Area 13 ebikes.  They make a tool just for that freewheel removal. Rad will sell you one but it's not as good as the one from Area 13 Ebikes. It's on there web site under tools and cost $49.99. I got one 10 bucks cheaper on sale. Other tools won't fit over the axle nut and wire plug of the Bafang motors.
