Trek Wahoo 20 Trail Emerald Iris: the garrigue at a child's height

Wide tyres, disc brakes and nine gears: the Trek Wahoo 20 Trail brings mountain bike equipment to a 20-inch format, for children from 1.14 to 1.32 m. Trek quotes it at 9.85 kg in one size, Alpha Silver aluminium frame included. Emerald Iris is a deep emerald green with subtle iridescent highlights.

Who is it for?

For the little mountain biker who loves dirt tracks, bumps and rocky sections, like those in the garrigue around Béziers. It also suits families who head off on mountain bike weekends and want their child to have a bike that is up to the job.

The LVR workshop view

Alpha Silver aluminium, built here for the trails. The Wahoo 20 Trail uses Trek's Alpha alloy but kits it out like a little mountain bike: hydraulic callipers on a Post Mount fork, 6-bolt disc hubs and a narrow-wide chainring that holds the chain in place over bumps.

	Wahoo 20 Trail (this bike)	Wahoo 20 Path	Wahoo 24 Trail
Frame	Alpha Silver 20 inch	Alpha Silver 20 inch	Alpha Silver 24 inch
Fork / brakes	Rigid, 160 mm hydraulic discs	Alloy, V-brake	Rigid, 160 mm hydraulic discs
Tyres	Kenda Amrak 2.20 in	Connection Comp 2.00 in	Kenda Amrak 2.20 in
What it means	Fingertip braking, 9 speeds	1.10 kg lighter, for the road	The logical next step, from 1.30 m

In other words: the 20 Trail weighs 1.10 kg more than the 20 Path, but it brings hydraulic disc brakes, a ninth gear and wider tyres. It is the choice for children who already want to ride off the beaten path.

The 2.20-inch Kenda Amrak tyres offer more volume than the 2.00-inch tyres on the Wahoo Path: they grip better on dusty ground and smooth out small stones. With no suspension, this air volume does most of the work for comfort, provided the pressure is set correctly, which we do at handover.

The 580 mm handlebar and its short 45 mm stem give lively steering, ideal for weaving between trees or rocks. The nylon VP-225 platform pedals offer a wide contact area for trainers.

Which Wahoo should you choose?

Model	Wheels / child's height	Gears	Brakes	Weight
Wahoo 20 Path	20 in / 1.14 to 1.32 m	8	V-brake	8.75 kg
Wahoo 20 Trail	20 in / 1.14 to 1.32 m	9	Hydraulic discs	9.85 kg
Precaliber 20 7-speed	20 in / 1.14 to 1.32 m	7	V-brake	10.90 kg
Wahoo 24 Trail	24 in / 1.30 to 1.50 m	9	Hydraulic discs	10.50 kg

Our take: if your child is nearing 1.30 m and rides mostly off-road, the Wahoo 24 Trail (10.50 kg) will take over with an 11-42 cassette. For roads and greenways, the 20 Path remains lighter at 8.75 kg.

LVR sizing advice

Trek's height range for this Wahoo 20 Trail runs from 1.14 to 1.32 m. On a trail bike, your child should be able to stand on the pedals with some clearance above the frame. Come and try it with them at our Béziers shop: we adjust the saddle on the spot.

Size	20 inch
Child's height (cm)	114-132
Cranks (mm)	115
Seatpost (mm)	230
Handlebar width (mm)	580

Your questions

What tyre pressure?	It depends on your child's weight and the terrain: we set it with you in the shop.
Will the bike survive falls?	The aluminium frame is tough; after a big fall, have the derailleur checked.
Can clipless pedals be fitted?	There is no need at this age; platform pedals are safer.
Is the green glittery?	It is an emerald green with iridescent highlights, more subtle than glitter.

The LVR Cycles verdict

A real little mountain bike for discovering trails, with powerful brakes and grippy tyres. Its iridescent emerald green gives it a bold character.

Pros
+ Grippy 2.20-inch tyres
+ Lively, precise steering
+ Wide platform pedals

Cons
- Rigid fork
- Not as light as a Path

Why buy from LVR Cycles? In Béziers, we set the tyre pressure according to your child's weight, check the wheels are properly tightened and take care of brake bleeding and drivetrain servicing.
