I have a Rad Rover drop frame, am 5'9" tall, and have difficulty getting on and off the seat because my legs are too short.
The solution was an inexpensive seat post that can be adjusted up or down while riding. It goes down over 6" with a push of a button, which enables me to get on and off easily.
I attached a picture of what I purchased on Amazon.
Thanks for sharing. I think this is an accessory not many folks know about. I might see if I can do a review on one of these to share on my YouTube channel. That price also seems extremely reasonable.
