Hi guys I got this bike for free. Rode it but I have no idea about changing gears at all with it. Haven’t ridden a bike in years. People keep saying it’s too small for me but I love it and was comfortable to ride and I could get my feet on the floor. I need to get outside in the garden and give it some maintenance however what do I do. I basically picked it up and rode it for an hour home was fine brakes need a bit of work but I’m trying to find out about gears. It’s a Raleigh Panache any help would be appreciated. I’m looking on YouTube etc but haven’t found much info on it as yet.
