Best sequence of events would be:
1. Practice balancing and steering with the seat down and the bike coasting rather than being pedalled.
2. Practice starting and stopping with the seat up in a more appropriate riding position.
3. Then move on to improving riding skills and techniques, and appropriate road use.
