I got a folding bike 2 months ago and got my first hiccup. It has a 3-speed hub gear and while changing gears today, it seems like the chain slipped off the smaller chainring near the back wheel into the gap with the wheel. As the chain is quite tight, my basic knowledge or Youtube info on how put chains back on in dérailleur bikes is useless.
How do you actually slide it back on? Is there a simple technique? I tried simply pedalling but it doesn't seem to make a difference.
If this matters, it's an S-RAM iMotion hub gear.
