| Specification | |
| Features | |
| 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 | |
