I have decided to purchase an Xootr Swift and would like to ask you some questions as to the possibility of upgrading the bike with an Internal Gear Hub. My questions are the following:
1. What kind of (brand and model) IGH will I need to upgrade the Xootr Swift?
2. What parts needs to be replaced?
3. Will this upgrade make the bike lighter? Faster?
4. What would you consider be an average cost for this upgrade (parts and labor)?
Thanks in advance for your help.
