Shyre Eastie 20" Wheel Kids Mountain Bike
Free UK delivery
The first bike built for the trails.
For riders ready to follow you off the path, whether they are moving up from a hybrid or starting out off-road. A suspension fork, disc brakes and seven gears, so rough ground stops being the thing that turns them back.
Will it fit?

A suspension fork and disc brakes on a 20in bike is an unusual pairing at any price. The fork keeps the front wheel settled over roots and stone rather than skipping off them, and the discs mean a rider can slow down properly on a wet descent. Between them they decide whether a first trail ride ends with a child asking to go again.
What you get
- Front suspension fork, 40mm of travel. The fork compresses over roots and stone instead of bouncing the front wheel off line, so they hold their speed and their nerve on ground that would otherwise stop them.
- Mechanical disc brakes, front and rear. The pads grip a steel rotor at the hub rather than the wet rim, so the stopping power is the same in November as it is in July. Levers sized for their hands, so they can use it.
- Shyre Junior Fit. 140mm cranks, a 500mm bar and a junior saddle. The shorter pedal circle suits a child’s leg length, and the narrower bar puts their hands at shoulder width rather than beyond it, which is what makes a bike feel controllable off-road.
- Shimano 7-speed drivetrain with a thumb shifter. One shifter on the right, worked with the thumb, so changing gear is a click rather than a job. A Tourney rear mech and enough range to get them up a climb sitting down.
- 6061 aluminium frame, 12kg ready to ride. Weighed with the pedals and kickstand on. Heavier than our hybrids, because that is what a fork and discs weigh, and it is covered for life.
- 28-hole double-wall alloy rims on 2.35in tyres. Double-wall rims and a higher spoke count take repeated drops better than a lighter road wheel, and the wide tyre gives grip in mud without feeling slow on the way there.
- Quick-release seatpost clamp and kickstand. Drop the saddle for a descent, raise it for the climb back, no tools needed.
If they have never ridden off-road
Start on a blue-graded trail rather than a bridleway. Trail centres grade their routes, and a blue is built to be ridden by someone still learning, with the surprises taken out of it.
Let them lead. Riders pick their own line better than they follow yours, and the ride lasts longer when they are setting the pace. A pair of gloves is worth more than any other bit of kit at this stage.
How to measure their inside leg
Stand them against a wall with their shoes on. Hold a hardback book between their legs, spine upwards, and raise it until it sits comfortably. Measure from the top of the spine to the floor.
This is more reliable than age. Children of the same age can differ by 15 to 20cm in height, and as much again in leg length.
Buying from us
Lifetime frame and fork warranty, and it transfers with the bike
If a frame or fork fails we replace the bike, not just the part. Everything else is covered for two years. Pass it on to a younger sibling or sell it when they outgrow it, and the cover goes with it.
90 days to change your mind
Take your time deciding whether it fits and whether they get on with it.
Shyre Trade Up — to 55% back
Send us a photograph when they outgrow it and we will agree a value towards their next bike before you commit to anything.
We will match the price
If you find a comparable bike from another brand for less, send us the link and we will match it. It needs to be the same wheel size, with an alloy frame and equivalent brakes and gearing, new and in stock at a UK retailer.
It arrives 90% built
A basic tool kit is in the box and there are assembly videos to follow. If you would rather someone talked you through it, book a video call and we will go through it with you. If you would rather not do it at all, there is little enough left that most local bike shops will finish it off for a small charge.
Named after Eastridge Woods, where Kev rode as a boy with his mates. Eastridge hosted the British national championships through the nineties, and riders like Andy Titley, Steve Peat and Rob Warner raced there.
