So I’m 225 lb and 6 feet tall, yes I watch lot of YouTube videos , especially global cycling network for learning. At first I had trouble riding standing and then a video about how you should lean forward over the handle bar and sway the bike really helped and eliminated knee pain when riding out of saddle.
i just bought my bike less then a month ago and was interested in biking for 4-5 months. I’m really enjoying the journey!
