You don't need an alibi to have fun, and with Bell's Alibi helmet protecting your kids dome, having fun was never so safe! The Alibi looks and feels just like the helmets Mom and Dad wear on their fancy bikes, and is actually sized pretty closely to an adult small, so it's suitable for kids about 9-13 or for adults with small heads.
Strengths: Saved my life. Fairly light - fits VERY well. Saved my life a second time.
Weaknesses: Not as light as it could be - bit tricky to fit night lights to.
Bottom Line:
I crashed on my road bike last Sunday. Hit my head hard enought to crack the helmet in two places and give myself a grade II concussion. I'm quite sure that without this (perhaps any approved) helmet - I'd be dead.
While I've moved to a Giro Indicator, this was a great helmet and also saved me injury once before in an MTB crash.
Can't say enough about Bell/Giro helmets and the value of wearing them EVERY ride.
