Cycles can become better

Today morning while taking my younger Daughter's cycle, i realised that Brakes were very hard on my fingers.

If this is the case... I pondered all thro' the push/ pull cycle effect, that it would be very hard on any 4~8 year old child as it would be hard to apply these brakes.

Upon closer inspection, I found the following

1. friction free cables not used
2. return spring of higher tension
3. akward lever position which is beyond the reach of any small child to apply the brakes.

There has been enough research which has gone into all these areas... It makes me wonder why the cycle industry is yet to embrace them... Is it lack of glamour to the industry which make it that way ?
