The extra versions allow kids to explore other pedal rides that are rarely seen, the tadpole trike is for kids that have mastered pedaling on two wheels already, it requires a different balance skill.
The pedal trike and pedal quad are great for kids with balance issues or confidence problems, and are still fun and a challenge for any kid.
Stroller kit: stretch goal.
The Stroller is under further development and will be released soon as an optional extra.
