Bicycle Womens/Mens Large - 36" leg- (Dean EH3)

Large bike to get about Edinburgh town...while helping out family...
Im 6ft tall (36inch leg) and arthritic,
so a large frame, gears,
ideally a step thru frame, is helpful

BUT ANY WOULD BE GOOD PLEASE!

Electric would be great!

Im very low income = can't afford a new bike... and not found a secondhand one yet in edinburgh that fits!

Recently recovered from hip replacement from surgery...
