Who is it for?

For the 5 to 8 year old who joins their parents on rides of several kilometres, and for families who want to head out together at the weekend without having to push their child's bike up every hill.

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.

On a family ride, the difference in pace between parents and child is often the main problem. With seven gears, your child keeps a steady cadence, uphill and on the flat, and tires less quickly. The KMC Z7 chain and SunRun 14-28 freewheel are common parts, easy to replace in the workshop.

The 130 mm grips give a good hold for a child's hands at this age, and the 560 mm handlebar provides control in corners. For a first proper ride, the Canal du Midi towpath towards Colombiers is flat and car-free.

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 four colours of the Precaliber 20 7-speed are identical at 10.90 kg; midnight blue is the most understated. For more technical trails, the Wahoo 20 Trail (9.85 kg) moves up to 9 speeds and hydraulic disc brakes.

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

Can they ride 15 km?	It depends on the child; with gears and breaks, rides quickly get longer.
Do the parts wear quickly?	The chain and freewheel are standard parts, simple to replace.
Is the kickstand included?	Yes, as standard.
Is the blue dark?	Yes, it is a deep, elegant midnight blue.

Pros
+ 7 speeds to keep up with the parents
+ Standard wear parts
+ Understated midnight blue

- 10.90 kg to carry
- Dark colour best paired with lights
