Changing to Internal Hub Mini Velo
Hey everyone!
Bit of newbie here, but I am planning to purchase the bike that I included below(a 7 speed derailleur). For various reasons I prefer a internal hub gearing system. I was hoping to get some advice on what hubs I can look into that would fit this bike (I believe it is 20" wheels) and what steps would I need to take to perform the conversion.

Thanks!

Looking at the red bike, looks like it could take an IGH ..knowing the rear drop out spacing would help to recommend a hub that would be easily compatible.. I imagine it is around 120mm .. that would open it up to most 3 speeds, a couple of 5 speeds, and at least one 8 speed..

I bought a Nexus 8 speed as a replacement but have not built a wheel yet.

Out of curiosity, how do I install an IGH on a bike that either is single speed, or has a derailleur?
Is that it?
- Check overlocknut distance (OLD) to make sure the gear hub will fit
- Find a way to tune the chain tension, either through a horizontal dropout, chain tensioner, or an eccentric bottom bracket
- Build new wheel with gear hub; Make sure it's the right strength considering a gear hub weighs more
- Install matching speed shifter on handlebar, and run cable from shifter to gear hub.
Is that it?

About the anti-rotation washers:
1. Do they fit any dropout?
2. Are they needed because the gears in the hub rotate around the central axis, hence the need for those washers to keep it from rotating?

They should fit most dropouts. According to Sheldon Brown, some older dropouts may need to be filed if Nexus/Alfine washers are used. If you are using Nexus/Alfine, you must order the correct washers for your dropout configuration.

The washers will either be vertical or horizontal. You just need to see which one your bike takes.
