The Trek Precaliber 20 7-speed introduces children to changing gear: a Shimano Tourney TY300 derailleur, a SunRun 14-28 freewheel and a 35 mm suspension fork, on 20-inch wheels.

Who is it for?

For 5 to 8 year olds who are confident on a bike and ready to learn about gears, and for families who ride hilly routes or dirt tracks. It is well suited to Sunday rides that string together small climbs and descents.

The LVR workshop view

An Alpha Silver frame that takes gears and suspension. On a 20-inch Alpha Silver aluminium base, Trek fits a suspension fork with 35 mm of travel, a Shimano Tourney TY300 derailleur and a seven-sprocket SunRun 14-28 freewheel. The linear-pull brakes and kickstand remain standard: this is a more complete Precaliber, designed to leave the tarmac behind.

	Precaliber 20 Freewheel	Precaliber 20 7-speed	Wahoo 20 Trail
Stage	No gears	Gears and suspension	Trail bike
Frame / fork	Alpha Silver alloy / steel	Alpha Silver alloy / 35 mm fork	Alpha Silver alloy / rigid fork
Reference bike	9.45 kg, 114 to 132 cm	10.90 kg, 114 to 132 cm	9.85 kg, 114 to 132 cm
What it means	Simple and light	Climbs better, soaks up bumps	Hydraulic disc brakes

In other words: 10.90 kg, seven gears, a fork that smooths out tracks and two hand brakes. The Precaliber for the 5 to 8 year old who wants to follow the grown-ups beyond the park.

Seven gears from 14 to 28 teeth give enough range to climb a hill without putting a foot down and to ride fast on the flat. Teach your child to change gear before the slope, while pedalling gently: the Tourney TY300 derailleur then shifts smoothly.

The 35 mm suspension fork smooths out roots and stones on tracks. It takes the strain off your child's arms and wrists, helping them hold their line. On tarmac you hardly notice it; on the white gravel tracks around Béziers, it brings real comfort.

Which Precaliber should you choose?

Model	Wheels	Child's height	Gears / brakes	Weight
Precaliber 20 Freewheel	20 in	114 to 132 cm	1 speed, 2 V-brakes	9.45 kg
Precaliber 20 7-speed	20 in	114 to 132 cm	7 speeds, 2 V-brakes, 35 mm fork	10.90 kg
Wahoo 20 Path	20 in	114 to 132 cm	8-speed microSHIFT, 2 V-brakes	8.75 kg
Wahoo 20 Trail	20 in	114 to 132 cm	9-speed microSHIFT, hydraulic discs	9.85 kg

Our take: at 10.90 kg, it weighs 1.45 kg more than the Precaliber 20 Freewheel, the trade-off for gears and suspension. The Wahoo 20 Path (8.75 kg, 8 speeds) is lighter but has no suspension fork.

LVR sizing advice

Trek recommends this 20-inch bike from 114 to 132 cm, or ages 5 to 8 according to its data. A child at the bottom of the range benefits from keeping the saddle low for the first few weeks, then raising it as they progress. Come and try it with them at our Béziers shop.

Size	20 inch
Child's height (cm)	114 to 132
Age given by Trek	5 to 8 years
Fork (mm)	35
