Considering switching to IGH for my Fatbike.

[Kaldeem]

I've had various problems with my DIY build. Most of them centering around the distance the chain has to extend from the Granny gear, and following 3 closest gears. In my set-up, it's an 8 speed, so I'm talking about 1-3 gear. My bike keeps dropping the chain, and I've taken it to 2 shops, they won't touch it, with the exception of purchasing a new rear wheel with a IGH.

My question is what do I need to know in order to do this myself? I've re-laced wheels before, so I'm not worried about that, but I know very little about IGH's and how to measure them for your wheel.

I've read up a little on electricbike.com and I'm just curious as to what EBR community thinks, along with some advice on a good 3-5 speed IGH.

Thanks guys!

was hoping you would get more input on this, please keep us up to date if you do the IGH and how it goes

I think Karl over at electric-fatbike.com did a setup on fatbike with an IGH and BBS02.

Nuvinci is the hot setup by far these days. Infinite adjustments within the gear range and you can buy 1 for $200. There are some cheaper 3 speed hubs, SRAM, others and then they go to about 8 as the next step with Shimano. Can't think of anything between 3 and 8 (US).

This new technology from Bike2

will eliminate any drive alignment issues currently experienced by using large ratio gearing on rear cassettes
Looks likely to succeed as the system will allow limitless options not only for the e-biking community but for any mobility market
The conventional e-bike as we know it with the traditional mechanical connection from crank to rear gearing may be a thing of the past
It's exciting to think how designers will use this technology and take e-bike design to another level when this new system gets more attention

If the electronics fail or the battery is dead you can't ride the bike.\
So it's a rear hub motor, but with NO gear range whatsoever....

That's not an advance.
