Frog upgrade

Bought for my 4 yr old daughter who whilst not quite tall enough for the 52, desperately needed gears. A change of saddle and bars makes the 52 a perfect fit. Only shame is the trigger gears that make down shifts difficult for young thumbs. A grip shift option would be a better choice. But, I’m sure her thumb will develop enough strength to eventually change down.

Brilliant kids bike.

I have to be honest this felt like a lot of money to spend on a child’s bike but within 15 mins I knew it was a great buy. Much lighter and easier for my daughter to handle than her previous cheap and cheerful high-street bike. She is slowly getting the hang of the gears and we are now able to cycle to school and back via roads, trails and fields. The bike is handling all terrains well and my daughters confidence cycling is blossoming. I am optimistic this will be a great hand me down to my son too so over the next few years should work out to be really good value for money.

Forg 52 20w 2017- kids bike

Dear Tredz, I just wanted to say thanks for my order that was delivered this week. I ordered a Team Sky Frog bike for my Grandson last weekend which arrived promptly this week. I was particularly impressed with the speed and the update I received about the delivery as well as the way the bike was packaged. I am highly impressed with the level of service considering it was an internet order and you are a credit to the cycle industry. I look forward to buying further bikes from you in the future. Kind regards Ron

Kids Bike Guide

 

Which bike is best for my child?

The best kids' bike is one that fits properly - a bike that is too big or too small will be hard to ride and may put your child off cycling. See our Kids' Bike Size Guide for more info on kids' bike sizing. While it may seem like a good idea to buy a bike that your child will ‘grow into', if it is too big it may discourage them from riding. Similarly, a heavy bike is hard to ride, especially for young children. A correctly sized lightweight bike will give your kids the best start on their cycling journey.


Balance Bikes

A balance bike is the simplest type of bike. With no pedals, gears or even brakes (on some models) to worry about, balancing skills are easily learned. Balance bikes generally have 10” or 12” wheels and are suitable for children aged one to four years. Some balance bikes have larger 14” wheels for children up to six years old.

Balance bikes

Pedal Bikes

Once children have learned how to balance, the step up to a pedal bike is easy. Some pedal bikes come with removable stabilizers. While stabilizers are the traditional way of learning to ride a bike, many cycling instructors will advise you to avoid using them. There is good reason for this because, while stabilizers allow your child to learn how to pedal and brake, they make it harder for them to learn how to balance later on.

Pedal bikes are all fitted with brakes. Learning to stop is the next most important skill to learn after balance, so it is a good idea to make sure your kids can do this before you let them pedal away. Larger pedal bikes may also have a number of gears to help them up the hills.

Pedal bikes

Wheel Size

For the most part kids bike sizing is based on wheel size. Bikes with a 10” or 12” wheel diameter are best for 2 - 4 year olds and include both pedal and balance bikes. Kids aged 4 - 6 years will find the best fit on a 14” – 18” bike. These bikes have a simple single speed drivetrain with easy to use brakes and kid friendly components. Moving up to kids bikes with 20” wheels you will start to find geared drivetrains with easy to ride mountain bike style components.

Junior bikes, for older kids, have larger 24” wheels which are more like scaled down adult bikes. Some kids bike brands, like Frog, also offer different frame sizes within specific wheel sizes. See the kids bike size tab for more comprehensive sizing info on this bike.

Kids' Bike Wheel Sizes

How to get the right fit

Once you have chosen the correct size bike using the kids bike size tab information on the product page there are a couple of adjustments that you can make to get the perfect fit for your child.

Saddle Height

Set the saddle height so that they can put both feet flat on the ground. This will give them the confidence to stop and start whenever they like and reduce the chances of them falling off. As they grow, move the saddle up to maintain the perfect fit. Once they have mastered the skills of balancing, pedalling, braking, and can steer their bike just where they want it to go, you can move the saddle up for a more efficient pedalling position.

Get the right fit - Adjust the saddle

Brake Reach

It is important that your child can reach the brakes easily without having to stretch their hands or unhook their thumb from the handle bars. It is easy to adjust the reach of the brake levers and move them closer to the handlebars allowing them to brake more easily. Most brake levers have a small screw that moves the brake lever closer to the bars, all you need is a small screwdriver or allen key to do this. Some premium kids' bikes even have a tool free reach adjustment nob. You may also need to adjust the brake cable tension with the barrel to get the brakes working optimally for your child.

Get the right fit - Adjust the brake reach

Handlebar Height

While this is less important than saddle height, you can also adjust the handlebar height on kids' bikes. This is easily done be repositioning the spacers (on a A-headset) or by loosening the expander bolt and repositioning the stem before retightening (on a quill stem). Start with the stem in its lowest position then move it higher it as they grow to maintain the ideal riding position.

Get the right fit - Adjust the handlebar height

Bike Weight

After sizing, weight has the biggest impact on your child's enjoyment while cycling. To understand why, remember that an adult bike can weigh around 20% of your body weight. Most kid's bikes can weigh up to a hefty 50% of their weight. Imagine strapping concrete blocks to your pedals and start riding, it wouldn't be a nice experience generally speaking. The more you spend on a kid's bike, the lighter it will be. This means the bike is easier to handle and manoeuvre, and that translates directly into fun and enjoyment.
