Verdikt
+Tugevused
- Introduction of gears opens up real terrain variety for growing riders
- Gripshift operation is well-matched to 6–8 year old fine motor skill level
- Low weight makes it easy for children to manoeuvre without adult help
−Nõrkused
- Gripshift can feel imprecise compared to trigger shifters older kids may prefer
- V-brakes less powerful in wet/muddy conditions vs disc brakes on higher-end models
- Premium price relative to 20-inch bikes at this age bracket
