The brat style rear loop became a real problem to make surprisingly. As simple as it looks because of the small size tubing and the inside of the bend diameter it was near impossible. The boys tried numerous techniques in the pipe bender, tried heat, asked a million different people but nothing.
Finally someone on a biking forum managed to do it in two parts and weld it together. With a huge relief Mackenzie was over the moon!
A helping hand with Ruby modelling the loop!
