My 2 oldest grand kids came over and we put the ct100u together. It was about the right amount of work for these 2 guys (11 and 9 years old). Installed the front fork, front fender and front wheel. I had to adjust the disc brake.
The mini bike fits them much better than the bigger ct200u. The boys were able to ride the bike briefly. Hope to give the bike a good work out when the weather warms up.
I will post pictures later of the ct200u and ct100u side by side.
