To get the right size bike for your child, the most important measurement is inside leg.
Stand your child against a wall, with their heels right against the wall. Put a book between their legs, as high as is comfortable. Ask them to step away from the wall, allowing you to measure from the floor to the top of the book (in cm).

Check our size guide to see what size of bike will best fit your child.

Don’t be tempted to go for a larger bike, it’s not safe for a child to ride a bike that they can’t easily control, or where their legs don’t comfortably reach the ground.

Frog Bikes are designed to grow with your child so you should get at least 18 months’ use out of the bike: the saddle height is easily adjusted, seat posts are long, handlebars can rise, and saddles can be moved backwards and forwards to match the growing reach of a child’s arms.

If a bike shop near you sells Frog Bikes, we recommend you go and try it out for yourself (see our list of Frog stores). If not, use the website to work out the right size and you can order directly from us. If you change your mind or need a different size, you have 28 days to return the bike. Please call us on +44 1784 557300 to find out the return cost.

When your child first sits on the bike, you need to check the saddle height. The balls of their feet should be able to reach the ground on both sides. most of our bike seats have quick-release levers so it is easy to adjust the saddle height.

Please see the manual online for full details of how to adjust the saddle and handlebars. If you need further help adjusting your bike, your local bike store should be able to assist.

If you buy direct from the website, you’ll need to attach the handlebars, put on the front wheel, front brakes, pedals, check all brakes are set correctly and set up the gears on the Frog 52 upwards. (apart from the Tadpole, where you’ll just need to attach the handlebars and check the brake). Full instructions are available in our online manual please follow the instructions and carry out all the checks and adjustments described.

Please note that the setting up of a Road Bike requires a more advanced knowledge of how to set up a bicycle. We highly recommend the bike is assembled and safety checked by a professional bike mechanic before your child rides it, which is one of the reasons we recommend everyone buys from a Frog store if at all possible.

To measure for a helmet, wrap a tape measure around the child's head just above the eyebrows and read the measurement in centimetres.

Most kids' helmets are sized either XS (around 46-53cm) or S (around 52-58cm). If your child's head is larger, then you should buy an adult helmet.
The average person's head is fully-grown at the age of 10, so you won't find your child needs a new helmet as often as they need a new bike!

When the helmet arrives, you need to ensure a good fit. All our helmets are adjustable, either with a twist at the back or by changing the thickness of the foam panels inside. The helmet should fit snugly and be comfortable to wear. When the child shakes or nods their head the helmet should remain secure. The helmet rim should sit on the forehead, just above the eyebrows. The helmet should NOT be tilted back leaving the forehead exposed or tipped so far forward that it covers their eyes.

We are very keen that old bikes don't fester in the corner of your garage, or even worse end up in a landfill.

We have a second-hand bike exchange scheme called Pre-Loved Frogs which is being run through some of our UK Frog stores.
Once you have outgrown your bike please talk to your nearest Frog store about exchanging it for the next size bike.

Very well, just take a look on eBay!

Some countries charge local import duty, taxes and admin fees for handling imports. These are the responsibility of the purchaser as Frog Bikes are unable to know all taxes charged by all local authorities.

The cost of buying our bikes direct from our website varies between countries, due to variations in shipping and taxation.

We would always advise that you buy your Frog bike from a Frog store within your own country: not only will the bike be built and checked for you by a qualified mechanic, you will also save on the shipping costs.

If you have used our Click and Collect method of purchasing a Frog Bike, a note of your order will be sent directly to your chosen Frog Bike Frog store. The Frog store will then order the bike from us. Once they have assembled the bike, they will be in touch to let you know your bike is available for collection. Please then pay the Frog store directly.


If you live in the UK, your bike directly to your address within 10 working days. If you live outside the UK, delivery will take up to 15 days. We will send you a tracking number so you can see when the courier will deliver it.

To arrange a return, please call us on +44 1784 557300 to arrange a collection. Please tell us if you would like a refund or an exchange. We’re sure you’ll understand that if it has been ridden outside we can only refund or exchange if it is faulty.


We recommend you take your bike to your local bike shop for a service after the first 6 weeks of riding, as cables tend to stretch a bit at first. If you are mechanically minded, you should regularly check your bike anyway: look out for signs of wear in the brake pads, keep the chain, gears and gear-changer well oiled especially after washing the bike or riding in the rain. Clean the mud off it after each ride, and avoid leaving it damp. And take it to a qualified bike mechanic at your local bike shop every 6-12 months anyway for a full service.

This depends on how heavily it is used, and in what conditions. Ideally, a bike should be serviced every 6-12 months by a qualified mechanic at your local bike shop.

You may be wondering how to fit the mudguards. We're sorry that some versions of our manual do not give instructions. However, please see the online manuals for our original and updated versions - these will show you how to fit them, step by step.

Original Mudguard Manual

Updated Mudguard Manual

Your local bike shop will sell you replacement standard inner tubes. Check the dimensions written on your tyres to see what size you need, or see the detailed Tech Spec for each bike.

This is stamped on the bottom of the frame right between the pedal cranks (on the “bottom bracket”).

The front wheels all have a quick-release mechanism so you can easily take them off and re-attach them (except the Tadpole, 40 and 48). Check the user manual for instructions on how to disconnect the front brakes and remove the wheel – and how to reconnect them safely.

You can add panniers or a luggage rack to your bike. There are 2 ways to do this:

1. Purchase a pannier rack that fits onto the seat post, e.g. one of the following:
BBB Carrier MountRack BCA-02 weighs 100g
PedalPro seatpost mounted rear luggage rack weighs 600g
Rixen & Kaul Freerack Plus BZ820 aluminium seatpost-mounted rack
TACTUFF Rear Luggage Beam Rack weighs 1.1kg
Avenir Pioneer Urban or Urban Elite weighs 3kg
Alloy Seatpost Mounting Rear Rack/Carrier
ETC Cycle Bike Rear Pannier rack (seat post fit) weighs 900g
Keirin seatpost luggage rack

2. Purchase a normal set of pannier racks for example Ventura rack and add either
M-Part Seatclamp And Rackmount or
Bontrager Eyeleted Seatpost Clamps

See this image for details: https://www.frogbikes.com/blog/?p=708

You can attach a kickstand to the bottom bracket of all Frog bikes, from size Frog 40 upwards.

We sell them on our website Here or you can get them at many local bike stores too.

We recommend the Follow-Me Tandem for our smaller bikes. Please source it through http://www.followmetandem.co.uk or http://www.followme-tandem.com

These devices are increasingly popular and there are a number of different makes and models on the market. The Followme tandem (with the hollow axle fitting kit) has impressed us with its design and the quality of its components, we understand that it works well with our smaller bikes.

Please note many of these tag-along attachments require a specific fitting kit for use on what are known as hollow axles. All our small bikes have hollow axles. For example, Followme has a specific version/kit that must be used so please ensure that you buy the correct fitting kit or version.

We always recommend that you have these sort of devices fitted/installed and checked by a qualified cycle mechanic. Please note that fitting of these type of kits may invalidate your warranty.

Yes, this is easy to do. Please watch this short video to show you how:


We always recommend that a qualified bike mechanic checks your bike thoroughly before your child starts to ride it.

The current European standards (EN14765) state that pedal bikes up to 16” need to be supplied with a chain guard, so our Frog 40 and 48 have a chain guard included in the box.

Many models sold in the UK do not have a chain guard and many parents would prefer not to have it fitted so we suggest to stores that they ask customers whether they would like to have it fitted or not.


Balance bikes are ideal from the age of 2 upwards. As long as the rider can get both feet flat on the ground, they will enjoy riding it. But if your child is older, then they can, of course, learn to ride at any age! Just make sure you get them a lightweight bike that is not too big for them: a big bike is not as safe, and it may even put them off.

We recommend starting on a lightweight balance bike from a young age (2-3 years) as balance is so important in riding. Kids will enjoy the freedom of a set of wheels and the transition to a “proper” bike with pedals will be relatively smooth. Balance bikes can handle much rougher terrain than stabiliser wheels, as their wheels are so much bigger.

If your child is too big for a balance bike, get them a lightweight bike which is the right height for them, and take off the pedals for a few weeks and use it as a balance bike. It won't take them long to get the hang of it, then add back the pedals and they'll be off!

There are advantages to both, but most cycling professionals would recommend the balance option. Balance is so important in learning to ride, and honestly using stabilisers for a few months (or longer) only delays the process. When the stabilisers go, the child still has to learn to balance, and by that time they can be much bigger, which means a higher centre of gravity. Also, a balance bike can be taken on much rougher terrain than stabilisers – whether it’s a grassy park or the woods.If kids start their cycling career on a lightweight balance bike, when it’s time to move on they only have to learn to pedal – this is much more straight-forward than learning to balance.

If your child is a bit too tall for a balance bike, you should buy the right size bike for them (see our size guide) and simply not attach the pedals for a while. They can learn to balance and scoot around on their bike, and when they feel ready, just add the pedals.

Should you decide that you need stabilisers for a while, the best ones we have found for the Frog 40 and 48 are the EZ Trainer Suspension Stabiliser 12-16" Wheel from Adie. Your local Frog Frog stores can fit these with a change of axle. They comply with EN 14765.

For bigger bikes, only on the Frog 52 single-speed we are able to fit our own stabilisers, your local Frog stockist will be able to help you in correctly fitting them.

Can you imagine riding a bike that’s half your own body weight? That’s what lots of steel kids’ bikes are like. But a lightweight bike is easier for children to balance, control and enjoy, and faster to ride! It’s also easier for parents to carry or load onto a roof-rack. Frog Bikes are all aluminium, which makes them some of the very lightest bikes on the market.

Depending on how fast your child grows of course, we expect that most of our bikes will last you about 18 months to 2 years. They are designed with “stretch” so the saddle height is easily adjusted, seat posts are long, handlebars can rise and also a longer stem can be added ( you will need to go to your local Frog store to do this), and saddles can be moved backwards to match the growing reach of a child’s arms.


British Cycling stipulates gear restrictions for kids' track bikes, to reduce the risk of over-use injuries, avoid strength imbalances in young riders, and ensure all riders compete on an equal footing. We have taken a conservative view of the age of our riders, and for each of our track bike sizes our standard gear ratios give a shorter roll-out than BC standards allow.

If your child can comfortably handle larger gear ratios, your local bike store will be able to swap out the relevant parts.

BC Restrictions:
Under 14: 6.45m.
Under 12: 6.05m.
Under 10: 5.4m.
Under 8: 5.1m.

Frog roll-outs:
Frog Track 70: 5.2m.
Frog Track 67: 4.73m.
Frog Track 58: 3.66m.

Every single Frog bikes frame, fork and component is rigorously tested and conforms to EN, ISO and CPSC standards.

The Tadpole and Tadpole Plus have passed EN71 (Toys) which is the standard for Balance bikes.

The Frog 40 and 48 have passed EN14765, ISO 8098 and CPSC 1512 and are supplied with a full chainguard as standard, which stores can fit if requested when you collect the bike. US and Australian bikes include coaster wheels.

The Frog 52, 55, 62, 69, 73 and 78 have passed EN14764, ISO 4210 and CPSC 1512.

The Frog Road and Track 58, 67 and 70 have passed EN14781, ISO 4210 and CPSC 1512.

The Frog MTBs 62, 69 and 72 have passed ISO 4210 and CPSC 1512.

If you would like more details about the nature of the testing, and how our bikes conform to the standards, please contact us on info@frogbikes.com Further details are also available from BSI Standards Publications.
