Chain tension on hub geared E Bike
 

Hi ,

Can anyone tell me what kind of chain tension should I be looking for on a hub geared e bike ? Bike is a kahlkoff with nexus 8 speed gears

Is it similar say to a fixie or singlespeed road bike where I want an inch or so of up down play each way when setting chain tension ?

The chain tension can only be adjusted by moving the wheel back or forwards in the semi horizontal dropouts .

Thanks for any hep ,

You must have a little slack in the chain at the tightest spot. You will burn up bearings in a heartbeat if you run with too tight of a chain. With many factors in the roundness of your sprockets there will usually be a tight spot when turning the sprockets. Find it and loosen it so it disappears.

Good luck

To the OP --

It's considered bad form to start two threads on the same question. Pick a place and ask, and give it enough time to get some responses. If you don't get the answer you need, you might try again in another sub-forum, but otherwise, it's better if all the dialog is in the same place.

For those who wish to post, here's the other thread which seems to be more active, though the consensus is about the same hear and there.

If your bike has a derailleur mount, XLC makes single wheel chain tensioners that will take the slack out and probably quiet the drive system down at the same time. They are common on BMX bikes.

Here's the one I recently ordered for my 5spd IGH chain drive beach cruiser:

There are much more expensive models out there like the Surly Singeator.

Apologies I will know better in future
