Kids Bike Type Best For
Toddler Balance Bike No pedals — teaches steering and balance instinctively. Best for ages 18 months to 4 years before moving to a pedal bike. Lightweight, low step-over frame, soft tyres.
Kids Bike with Training Wheels Pedal bike with removable stabilisers — ideal for ages 3–6 learning to pedal for the first time. Training wheels provide stability while confidence builds.
Girls Bike with Basket Step-through frame, comfort saddle, front basket, and handlebar grips — designed for ease of use and style. Suits ages 4–10 depending on wheel size.
Boys Mountain Bike 20 Inch Scaled-down MTB geometry with 20” wheels, front suspension or rigid fork, and multi-speed gearing. Suited to kids aged 7–11 who ride on mixed terrain.
Kids Bike Age 5 to 12 Wheel sizes from 14” to 24” covering the full primary school age range — matching wheel size to height is the most important fit factor.

What to Look for When Buying a Kids Bike

Beyond wheel size, these four factors make the biggest difference to how well a kids bike fits, rides, and lasts:
Weight

Weight

The lighter the bike, the easier it is for a child to handle, steer, and pick up if they fall. Heavy bikes slow down learning and discourage riding. Look for bikes under 10kg for younger riders — weight is listed on every product page.

Brakes

Brakes

Hand brakes should be sized for small hands — check that your child can comfortably reach and squeeze the lever before ordering. Younger riders (under 5) often do better with a coaster brake (pedal backwards to stop) rather than hand levers.

Training wheels

Training wheels

A kids bike with training wheels gives stabiliser support while a child learns to pedal. Removable training wheels allow you to transition to independent riding when they're ready — most kids are ready to ride without them between ages 4–6.

Frame geometry

Frame geometry

A low step-over frame makes it easier for kids to mount and dismount safely. Girls bikes with basket designs typically use step-through frames — practical for shorter riders and easier for independent use.

Kids Bike Size Guide - Wheel Size by Age & Height

Wheel size is the most important spec when buying a kids bike. Age ranges are a guide — always prioritise your child's height for the most accurate fit:
Wheel Size Age Range Child Height Notes
12” 2–4 years Under 3'5” (105cm) Toddler first pedal bike — typically comes with training wheels
14” 3–5 years 3'5”–3'9” (105–115cm) Early learner — training wheels recommended
16” 4–6 years 3'9”–4'0” (115–122cm) Confident beginner — most kids ready to ride without stabilisers
20” 6–9 years 4'0”–4'5” (122–135cm) Most popular size — boys mountain bike 20 inch and girls styles
24” 8–12 years 4'5”–5'0” (135–152cm) Older kids — near adult geometry, often with gears and disc brakes

Frequently Asked Questions

What size bike does my child need?
Kids bike sizing is based on wheel size, matched to your child's height rather than their age. As a guide: 12" suits children under 3'5" (roughly ages 2–4), 14" suits 3'5"–3'9" (ages 3–5), 16" suits 3'9"–4'0" (ages 4–6), 20" suits 4'0"–4'5" (ages 6–9), and 24" suits 4'5"–5'0" (ages 8–12). Always measure your child's height and check the size chart on each product page before ordering.
What is a balance bike and when should my child start on one?
A toddler balance bike has no pedals — children propel themselves with their feet and learn to steer and balance naturally. Most children start on a balance bike between 18 months and 3 years. The benefit is that kids who learn on a balance bike typically transition to a pedal bike without needing training wheels, often by age 3–4. Balance bikes are lightweight, low to the ground, and the most effective way to teach cycling fundamentals.
At what age should a child move from training wheels to riding independently?
Most children are ready to ride without training wheels between ages 4 and 6, depending on their confidence and coordination. The transition is easier for children who started on a balance bike. To help, lower the saddle so both feet can touch the ground flat, remove the training wheels, and let the child glide before adding pedalling. Most kids make the switch within a few sessions once they're ready.
What is the difference between a girls bike with basket and a standard kids bike?
A girls bike with basket typically features a step-through or low step-over frame for easy mounting, a front basket, swept-back handlebars for an upright riding position, and styling details in colours and finishes popular with younger girls. The step-through frame makes it easier for shorter riders to get on and off independently. Beyond styling, the riding mechanics are the same as a standard kids bike.
Is a 20 inch bike suitable for a 7-year-old?
Generally yes — a boys mountain bike 20 inch or girls 20" bike suits most children aged 6–9, with an approximate height range of 4'0"–4'5". However, height is more reliable than age for sizing. A tall 6-year-old may fit a 20" bike comfortably, while a shorter 8-year-old may still be on a 16". Always check your child's current height against the size chart on the product page.
Should I buy a kids bike with gears?
Gears add complexity — for children under 7, a single-speed bike is simpler to operate and maintain. From age 7–8 upwards, particularly on 20" and 24" bikes, gears become useful if the child rides on hills or varied terrain. Multi-speed kids bikes typically use a Shimano 6–7 speed drivetrain. If your child mostly rides on flat ground or paths, a single-speed is perfectly sufficient.
Do kids bikes come with helmets?
Kids bikes from Velozzo are sold without helmets — a helmet should always be purchased separately and fitted to your child's head for correct sizing. Helmets sized for adults do not protect children adequately. Browse our cycling accessories collection for kids-specific helmets with sizing guidance.
Do kids bikes come assembled?
All kids bikes from Velozzo arrive 85–95% assembled. Remaining steps typically include attaching pedals, adjusting seat height, and fitting or removing training wheels — this takes around 15–20 minutes with basic tools. Every order includes the required hardware and a step-by-step instruction sheet. If you need any help during assembly, our support team is available by email and chat.
Do you offer free shipping on children's bicycles?
Yes. Every kids bike order ships free to addresses across the continental USA. No minimum spend applies and no delivery charge is added at checkout. The price shown on the product page is the final price you pay.
