i tried it out today and hit my knees. i'm 160 tall. tretmann under a table doesn't work.

Good day
Thank you for your interest. I don't know why this advert is still active, as the bike was sold a long time ago.
However, I have a really great bike (Sportstech SX500) for sale for indoor use. It has hardly been used and is absolutely as good as new.

I tried under a table, but I couldn't do it without touching my knees.

i'm trying it out today. i wouldn't use it under a table for another reason. if i set resistance, the chair slowly jerks backwards. it's better to use the trainer on a wall.
