We introduced kids bikes the internal gears in 2013 and they have been a huge success. They are popular with the kids because this has no external gear parts you can damage - treat it rough! We use the premium Shimano 3 speed internal gear system and add a custom designed protective guard for that extra peace of mind. Whilst you are still learning to handle your bike and gears, you also have a foot brake as well plus two handbrakes. And finally one great consideration about the internal geared bikes is that the bikes performance can grow technically with the child's ability.
