Rookie 18 Convertible Pedal Bike

Stepping up to a pedal bike introduces many new skills at once; Braking, Pedaling, Steering, Speed control, and fine-tuning balance, all at the same time. Children also need time to adjust to bigger and heavier bikes. Breaking this down into small learning steps makes the whole process far more manageable, and much more fun.

The Rookie 18 develops kids into confident riders



Pedal Kit included

The Rookie 18 inch that works perfectly in pedals off mode then converts to an ergonomic, quality lightweight pedal bike; designed to perform in either method.

It’s incredibly lightweight and durable with a 6061 aluminium frame and top-quality alloy components. For children aged 4-years-old plus.


The Rookie 18″ weighs in at just 6Kg in pedals off mode with a minimum seat height of 48cm. The bike will fit kids aged four years plus. It is ideal for those just starting their cycling journey or for experienced riders coming off a smaller bike. Works for those who need time to get used to brakes or balance with a larger frame & wheels. Beneficial for kids needing extra support if facing balance challenges such as dyspraxia.


Our pedal kit transforms the bike by adding the included equipment. Fitting the pedal kit is quickly done using Allen keys provided. At just 7.3 kg in pedal bike mode, this bike will give you the performance of more expensive bikes, but with the added benefit of turning the bike into a lightweight, ergonomic pedal bike at a more affordable price. The maximum seat height is 63.5cm. Plus, since it retains the same geometry and handling between modes of operation, the child’s learning lag is virtually non-existent. The Rookie range of convertible pedal bikes is sure to please even the most discerning of parents.

    Can't get over the quality of this bike, for the price its phenomenal. All the essential features have been carefully considered and included. I especially like the footrests and reach adjustment the bars and stem enable. Height adjustment is easy and the seat post has measurements too which is really helpful. It's so light a 2-year-old can lift it easily. It was so quick and easy to assemble my 7yo built it with minimal guidance. It's a really good looking bike with good quality robust components. I absolutely love it!

    What a fabulous little bike. Bought for my niece as a Christmas present. She is 16 months and absolutely loves it. The bike arrived well packaged, instructions were clear and an absolute bargain for the quality. Thank you so much!

    My 3 year old loves his Kidvelo Rookie 12. This is his 1st bike and he's taken to it like a duck to water. He is so confident with it and obviously feels safe. The bike is very fairly priced, it was delivered quickly, its lightweight, easy to put together, and the quality is fantastic. My little one loves the chunky wheels and the bell too. I would definitely recommend this bike to anyone who is looking for their child's first bike.

    I have recently purchased the Kidvelo Rookie 12 bike for my 3 year old granddaughter. The first thing to note is the website was very easy to use, delivery was quick and within an advised 1 hour time slot.

    The bike was packaged well and was simple to assemble, completed in under 10 minutes with all the tools required provided in the box. The first thing my granddaughter noticed was how bright the colour was, she loved it. After adjusting the seat height to suit she felt comfortable on the bike and couldn’t wait to get started. We took her to the local park and she where she just understood naturally how to use the bike and required limited guidance. Seeing her on the bike after just a few trips out I believe she will get much enjoyment out of using it and set her up perfectly for moving onto the next step.

    I don’t normally leave reviews, but I’m so impressed with our recent purchase of a Kidvelo bike that I thought this product was worthy of one. The first thing we noticed was the build quality of the product. It’s well made and really sturdy when put together. The black wheels and tyres look great and my little one loves the bright pink colour! I only wish I’d have known about this bike sooner as I would have bought one for my son, who seems to enjoy going on his little sisters bike more than his own! Thanks to all at Kidvelo for making a little girl really happy!

    Highly recommended Kidvelo Bikes Uk.
    We have the Rookie12 for our little boy. The bike feels super sturdy but lightweight for me to carry around where ever we are going! Super easy to put together my little man even got involved helping me put it together.
    My little one likes the extra features of the foot rest for going down little hills this also really helps with his balance for when he’s ready for the next size bike up.
    As a parent all the extra features with the handle bars and seat as they grow with him so I’m not having a buy a new one weekly is brilliant! “he don’t stop growing “😀
    Also the communication with Kidvelo Bikes Uk was Fantastic and all my questions answered.

    A Revelation!
    I work as a cycle instructor delivering Bikeability, Learn to Ride and led rides in the Town Park. I'm also the British Cycling Go-Ride lead at my cycling club. The club has been using a Rookie 12 to help keep younger siblings happy while brothers and sisters attend our sessions.
    The bike has been amazing, a revelation in fact. First of all, it's incredibly light, something that everyone comments upon. In fact, when the bike arrived we wondered if the box was empty!
    The steering has proper bearings, as do the hubs, so everything runs really freely. The MTB type handlebar stem is adjustable and the handlebars are shaped so that the reach can be tailored to the rider. The tyres are proper 12" pneumatic with Schrader (car type) valves and the relatively smooth tread pattern means there's the perfect combination of low rolling resistance and grip. There's a choice of 4 colours, but we have the bright green. You certainly can't miss it!
    I've come across lots of balance bikes, but this one stands way above anything else I've seen. You may find some of the features on other bikes, but the rookie 12 has them all in a brilliantly designed combination.
    Buy quality, your kids will thank you for it!

    I bought a Kidvelo Rookie 12 for my cousin. It’s incredibly light and the quality is fantastic. Delivery was free and the bike arrived the next day. Well packaged and easy to assemble. I totally recommend this bike for kids just starting out.
