Who is it for?

For the child who has gained confidence on a bike without gears and now wants to explore further, on cycle paths, tracks and quiet country lanes. It also suits a 5-year-old who is tall for their age and already at ease on two wheels.

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.

The Shimano Tourney TY300 derailleur is designed for leisure bikes: robust, simple to adjust and tolerant of slightly clumsy gear changes. That is exactly what is needed for a child who is learning, and who will sometimes forget to ease off when shifting gear.

The Alpha Silver frame comes with a 35 mm suspension fork, 20-inch wheels and 2.25-inch Bontrager XR1 tyres. This package lets your child ride the easy trails in the hills around Béziers, as long as they adapt their speed to the terrain and keep their helmet securely fastened.

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: the Precaliber 20 7-speed weighs 10.90 kg, compared with 9.45 kg for the Freewheel without gears. For a 5-year-old who is just starting out, the Freewheel is simpler; for a confident child, the 7 speeds open up new terrain.

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

Your questions

Is the derailleur fragile?	The Tourney is robust; an adjustment in the workshop after a fall is often all it needs.
Can it go on trails?	Yes, on easy trails, thanks to the 35 mm fork.
What is the difference with the Freewheel?	The gears and the suspension fork, for 1.45 kg more.
Is the mauve light?	Yes, a light, bright lavender mauve.

The LVR Cycles verdict

A complete Precaliber 20 for making progress, with its robust derailleur and suspension fork. Its light lavender mauve is soft and cheerful.

Pros
+ Robust Shimano derailleur
+ Fork for easy trails
+ Bright lavender mauve

Cons
- Heavier than the Freewheel
- Rim brakes

Why buy from LVR Cycles? In Béziers, we adjust the derailleur after minor falls, check the brakes and raise the saddle as your child grows.
