It looks in better condition than mine! Physically easy to change the lock, just one bolt, might be hard to source though, I ended up getting mine through Tredz as a special order as it needs to be the wider version that they didn't list at the time.
Edit, actually Tredz spent ages trying to list it but gave up in the end. I got it from Bike24 instead but don't think they post the UK anymore thanks to Brexit...
PS. I'm 6' and have no problem with saddle height interfering!
I love mine, daily school run with an 11 year old and 6 year old, still going well and we live at the bottom of a biggish hill. Battery life on mine is pretty depleted after 4 years / 7000 miles now so factor that in if the one you're looking at is similar usage!
