Frog Bikes Frog 53
Frog 53 Lightweight Kids' Hybrid Bike
Keep moving with gears
The Frog 53 is Frog's entry to bikes with gears for kids aged 5-8 years old who want to go further and faster. It comes with 8-speed Shimano gears, coupled with Frog's own easy to use child-friendly FrogFitTechnology® shifter. Child-specific features are found throughout whilst of course maintaining that crucial low weight of just 8.15kg.Designed and built in Great Britain, Frog hybrid bikes are perfect for roads, pavements, towpaths and forest trails. They come with mudguards and the option to attach a pannier rack to the frame, for ease of transporting school books and sports kits.
All new Frog frame
Frog have given their bikes a new lightweight makeover with the Frog 53. In addition to making the frame lighter, the bottom bracket has been lowered so feet can touch the ground easier and the fork steerer tube has been lengthened to give more adjustment at the handlebars.
FrogFit Technology® Cranks
Children's hips are smaller and putting them on a bike with adults size cranks will lead to the feet being further apart that the hips - a very unnatural position to ride in, whilst putting strain on the growing muscles and joints. Research showed the need for a reduction in the hip-pedal triangle so Frog introduced the reduced q-factor in their patented shortened cranks for more efficient pedaling (20% increase of efficiency in the lab).
FrogFit Technology® Shifter
The new FrogFit Technology® Shifter reduces the distance the lever has to travel by 65% over the previous lever, bringing a major improvement to Frog bikes. Smaller children can now shift to lower gears more easily and without looking down, allowing them to focus better on the road ahead and on having fun on the bike!
FrogFit Technology® Brake Levers
Smaller hands have a smaller reach. Frog's ergonomics-led design puts the brake lever closer to the handlebar while allowing for sufficient space for the index finger to reach the gear shifter. Being able to comfortably reach the brake and the gear shifter makes Frog bikes easier to handle and safer for children to ride.
Grips for kids!
Through using thinner grips on the smaller bike models, Frog bikes have a better feel and handling whilst also being more appropriate in size for smaller hands. A thinner grip is less tiring for the hands and forearms of children, making their ride easier and more fun!
Updated tyres
The new tyres for the Hybrid range are narrower, reduced in weight and utilise an improved tread pattern for better grip.
Rice Husk Pedals
Frog are committed to producing bikes in an environmentally conscious way. All Frog Hybrids are equipped with FrogFit Technology® pedals which are made of rice husk composite that uses 50% less plastic. Rice husks are a harvest bi-product, reducing waste and allowing Frog to use less plastic in their components.UK delivery
If your item is in stock and ordered before 12pm, we will do our best to despatch your order the day you place it. In busy times we tell you how long it will take us to process it.
The above does not apply to bikes, which we have to assemble and inspect before repacking for dispatch. Typically we try to have bike orders dispatched within 3-5 days, but in busier times it may take longer. In those cases we'll let you know of longer than expected delivery times.
Please bear in mind that we are closed on Wednesdays, so no items will be dispatched then.
Free postage over £40
For small items we use Royal Mail's 48 service which has a delivery time of typically 2-3 days from dispatch; though you do have the option to upgrade to 24 which is generally next-day from dispatch if you require your order sooner. Please note in some cases the item will need to be signed for, so please provide an address where someone will be in.
Orders of over £40 will qualify for free standard postage with Royal Mail 48. This may exclude certain bulky or awkward items which will be calculated automatically at the basket screen.
Bike shipping
When we send out a larger parcel such as a bike or trailer we use a next-day courier - usually either DPD or Parcelforce.
For these reasons please supply us with a delivery address where there will be someone in to sign for your parcel. If there is nobody in when the couriers call, they will leave a card. You can then phone them to arrange delivery for another day or collect your goods from your local depot (a photo ID with proof of address will be required).
How will my bike be delivered?
We fully assemble, safety check and inspect every bike as though you were going to ride it away from our showroom.
However, to get it back into a box suitable for a courier to handle, we have to remove the pedals, handlebar and usually the front wheel - so some minor reassembly is required when the bike is delivered to you.
Please bear in mind that you might need a 15mm spanner for the pedals (adult's bikes generally do not come with pedals included, so you may not need to worry about this), and 4mm, 5mm and 6mm allen/hex keys for the reassembly.
Outside the UK
Since Brexit it is no longer feasible for our website to have permanent shipping prices for international delivery. Instead, if there is an item you are interested in, please Contact Us with a full delivery address and we will quote for delivery.
All the prices on our website and catalogue are in pounds sterling and are inclusive of VAT, but VAT will be removed for international orders. Please bear in mind that you will likely have to pay your country's taxes, import duties and associated courier handling fees for any items.
