My son just turned 6, and he’s been mad about zwifting beside dad (you can register kids for free on Zwift). I got him a proper first road bike for his birthday (used, but in solid condition for its age) but his legs are about half an inch too short for the bottom of the pedal stroke. We wrapped about a half a roll of Gorilla Tape™️ as well as some anti-slip strips and it works! Today he joined me on the last ride of the Festive 500. He’s been beside me for a crazy amount of it.
