I haven't started looking... I am a little deflated atm. My mechanic mentioned off-hand that there are not a lot of options. If I want to increase the gear range, i.e. a little lower, then that just increases the gap between gears. The derailleur cage might not handle any larger cogs. Change the...

For what it's worth... It looks like this cannot be achieved with this motor, adding credence to Rad CS's '...good luck with your upgrade...' They used a motor that can't be switched to a Cassette freewheel, the axel is being part of the problem. The only recourse would be to switch out the...

re: RAD customer service - in the one correspondence I've had with them they couched their reply in company policy, ...tested for safety and functionality... Their business model seems geared (pun intended?) towards novice or people that would otherwise not be out riding? It's a good market...

Unfortunately, I already bought all the parts, only to find out about this 'Screw(y)' freewheel thingy. I had never heard of such a thing until visiting this forum! The notion of a Screw Freewheel seems antiquated and less versatile. Why they used a Screw on this bike is beyond me, to save a few...

I think my question got lost in the discussion, so I am posting it plain and simple... I have a 2021 Rad City with the Shengyi DD motor and the 6-7 sp Screw freewheel, 11-34 7sp. I would like to upgrade to a 10 speed, 11-40, or even 11-42. Is it even possible? This is not about more power, or...

Ah, so a little more education for me... http://www.ebikeschool.com/geared-hub-motors-vs-gearless-hub-motors/#:~:text=Geared%20hub%20motors%2C%20on%20the,a%20planetary%20gear%20reduction%20system.&text=This%20allows%20the%20motor%20to,a%20comparatively%20slower%20driving%20speed Nothing to do...

Sorry by RR, I meant Rad Rover, not Runner. The Rover 5 had the same 7sp set up as my current City and I didn't notice any 'geared' hub that I could change gears with...? But that's not the information I'm looking for. I am over the Rover, no good for my use case. A big behemoth, impossible to...

Hey, thanks... I first bought the RR5 fat bike (not a good fit for me) it did not have a geared hub, did it? It had the same 7 sp set up as the City, but a different motor. Anyways, I've moved on from that bike to the City, maybe not the best choice I'm beginning to think. Not really power I'm...

This link is for Bafang motor. This looks like a great route to go. Is the same route possible for the Shengyi motor that Rad now uses? I have a new Rad City 4 and am looking for LOWER gears and a smoother shifting experience. I would ultimately like to swap the 11-34 7sp freewheel, with a 11-40...
