minivelo 20 inch kid bike

The Minivelo 20 inch kid bike is a 20-inch single-speed aluminium kids' bike from the Minivelo brand, recommended by Jollymap for riders about 115–150 cm tall. The frame geometry is designed around a child's proportions, making it easy to get on and off and easier to separate from the bike in a fall, reducing the chance of injury. According to Jollymap's 2021 video, the first batch came with Tektro V-brakes, sealed-bearing hubs and short 127 mm cranks. The candy-colour body is available in 5 colours, including Brushed Silver.

What Problem Does It Solve?

Many parents look for a lighter bike for their child, and Jollymap's article "6 Factors to Consider When Choosing a Kids' Bike" points out that a bike's weight matters a lot for how easily a child learns to balance. In Jollymap's 2021 intro video, the 20-inch Minivelo weighs about 7.2 kg. The frame is designed to lower the saddle position, and the BMX-style saddle and shorter cranks let the saddle sit lower, so it does not need to be raised as high.

Geometry built around children

The frame geometry follows a child's body proportions, so getting on and off is easy, and in a fall it is easier to separate from the bike, reducing the chance of injury. According to Jollymap's 2021 video, the 20-inch model has a lower handlebar than the 16-inch, so the child's own weight keeps the front end planted for steadier riding.

Tektro V-brakes sized for small hands

The brakes are V-brakes from Taiwanese brand Tektro. Jollymap's 2021 video notes that both the V-brakes and the brake levers are designed for a child's hand size, so children can pull the levers and stop more easily.

Sealed-bearing hubs for smooth rolling

Many kids' bikes use loose ball bearings in the hubs; this bike uses sealed bearings. In Jollymap's 2021 video test, a wheel kept spinning freely for two to three minutes, so the bike rolls more smoothly.

BMX-style saddle and short 127 mm cranks

The seatpost has a quick-release clamp for height adjustment, and the saddle angle is set with a hex key from the top of the saddle, following BMX saddle design. This removes the clamp hardware under a conventional saddle, so the saddle can sit lower and weigh less. The 20-inch model has a 53–63 cm saddle height and 127 mm cranks; shorter cranks suit a child's leg length, so the saddle does not need to be set as high and pedalling is smoother.

Quick-release front wheel, training wheels optional

The front wheel has a quick-release design, which saves weight and makes storage easier. Jollymap's 2021 video also mentions that both the 16-inch and 20-inch Minivelo can be fitted with training wheels, so children who cannot ride yet can start with them.

Candy-colour body in 5 colours

The candy-colour body comes in Black Blue, Blue Green, Blue Red, Pink Yellow and Brushed Silver. Please refer to the colour options on the product page for current availability.

Who Is It For?

Good fit: Children about 115–150 cm tall (Jollymap spec) who can ride or are about to learn, and want a light single-speed bike.

Maybe not: If your child often rides up and down slopes and wants gears, compare the Minivelo 20 inch 8 Speed Kid Bike with the same 20-inch wheels. If your child is close to 150 cm or growing fast, compare the Minivelo 24 inch 8 Speed kid bike. Under 115 cm, compare the Minivelo 16 inch Kid Bike.

For sizing, see Jollymap's kids bike fit chart below. The chart is for reference only; the right size also depends on the individual bike's design and the child's riding skill.

How to Choose a Minivelo Size

The table below compares five Minivelo kids' bikes: the 14-inch, 16-inch and 20-inch single-speed models, plus the 20-inch and 24-inch 8-speed versions.

Sources: Jollymap shop spec tables, product information and Jollymap's 2021 intro video; Minivelo has no official spec sheet online. All five have aluminium frames. "—" means no data available. Components may vary between production batches.

• Want gears: The Minivelo 20 inch 8 Speed Kid Bike also has 20-inch wheels and the same 115–150 cm rider height in Jollymap's spec, with 8-speed gearing.
• Close to 150 cm: The Minivelo 24 inch 8 Speed kid bike (model GT24) suits riders 125–160 cm tall, with 8 speeds, V-brakes and a 9.3 kg net weight.
• Under 115 cm: The Minivelo 16 inch Kid Bike suits riders 100–130 cm tall; for smaller children there is the Minivelo 14 inch Kids Bike for 90–120 cm.

Jollymap's Advice

Besides height, check your child's inside leg length (inseam). According to Jollymap's article "6 Factors to Consider When Choosing a Kids' Bike", when the saddle is about 2 cm lower than the child's crotch height, the child can put both feet flat on the ground. This 20-inch single-speed model has a 53–63 cm saddle height, so measure your child's inseam to compare. If your child is between the 20-inch and 24-inch sizes, or you are not sure whether gears are needed, please tell us your child's height and inseam before ordering via Chat with us on our shop or the Jollymap Facebook page, and we will help you choose a size.

FAQ

What height of child does the Minivelo 20 inch kid bike suit?

Children about 115–150 cm tall (Jollymap spec). Choose a kids' bike by height and inseam rather than age alone: this bike has a 53–63 cm saddle height, and according to Jollymap's article, a saddle about 2 cm lower than the child's crotch height lets them put both feet flat on the ground. If unsure, contact us before ordering.

What is the difference between the Minivelo 20 inch single-speed and 8-speed?

The main difference is gearing. This Minivelo 20 inch kid bike is single speed, while the Minivelo 20 inch 8 Speed Kid Bike has 8-speed gearing. Both have 20-inch wheels and the same 115–150 cm rider height in Jollymap's spec.

How much does the Minivelo 20 inch kid bike weigh?
