The training wheels are very stable, the bike is hard and also appears to be very stable.
Only one star deduction for the amount of the handlebar ... This can not be adjusted further higher, as the cables from the front brakes are too short and are very tense at increasing the handlebar - therefore the bicycle brakes automatically, which is why we have this down again make had to do it but the seat easily down konnten- So our son got comfortable seating position for its size (112cm) ...
Otherwise very satisfied.
