The Dad Rat is the first model released under the Rat Bikes brand.

“I wanted a bike I could have a bit of fun on, but also do the chores like an emergency milk run or an evening leg burner. The Dad Rat is my vision of that. A gravel/XC frame inspired by middle-aged dads who once used to tear it up.” – Burf

Rat Bikes is still in the prototype phase. The sheet metal parts and frame build process, upon which this whole project hinges, was only an idea until the beginning of April 2025. I still need to do a bit of work before the frames are ready for the first batch of 10. I will do what I can to get this done as soon as possible, I’m hoping no later than the end of June for production.

You can show your faith in Rat Bikes by placing a pre-order now.
