This bike has hand brakes so kids can gain confidence using them before stepping up to a geared bike  
One speed is all you need – a simple set-up gives kids confidence and helps them stay in control  
You can replace the saddle's integrated handle with an integrated light mount to boost visibility on family adventures and solo excursions  
Like all Precaliber bikes, the frame is lower so it's easier for kids to stand over and hop on and off  
You shouldn't buy your kid's bike where you buy your cereal – Unlike big box brands, Trek kids' bikes are assembled by people who know bikes
