Well, a bicycle version of a metal and foam modeled T-Rex that is. Someone in Eugene Oregon is offering their custom built T-Rex bike for sale. It’s $2,000 on Craigslist, and is named after Sue. However, this dino is only 8½ feet tall, 12 feet long, and has a 5½ foot stance, which is close to the size of an adolescence T-Rex. She’s powered (by you) by a 9 speed drivetrain. If you’re of dino strength, you could get her up to 15mph, but 7mph is probably more realistic, but with a bit of adrenaline, you could go faster.
