ByK E-450x2i Kids Bike Features
With no external moving parts and designed by SRAM for electric bikes and folding bikes, the internal 2-speed i-motion gear system has been customised to suit the E-450.
At the heart of every ByK Bike is a well designed frame and weighing just 1.2kg our lightweight frame is easier to ride adn manoeuvre. The ergonomic design ensures a great fit and superb handling, your child will have a light and easy bike to ride. Our custom sized and shaped V-bars is another unique design - by considering shoulder width, riding position, safety and comfort our handlebars are made for kids.
With lightweight alloy wheels, we've made pedalling easier - our taller, more efficient wheel sizing has a dynamic advantage that other bikes can't match. And like the professionals, we've added radial spokes on the front wheel. Our smooth, faster-rolling tyres don't wear little legs out so quickly - the pattern is easy rolling and very robust.
To make a children's bike safe, the rider needs to be able to brake efficiently and confidently. We have used alloy front and rear callipers with light action for superior control and a simple and safe coaster style foot brake. The best of both worlds we believe. The custom-sized V-Brakes we have used are calibrated for age, ability and ergonomic fit. And they are made of non-flexing, strong and light alloy. Our light weight alloy rims ensure pedalling is easier. But more importantly alloy rims are a more efficient braking surface than cheaper, chrome-plated steel rims, and are therefore safer.
Little Details Count:
- Increased knee to handlebar clearance for growing bodies.

How to Choose the Right Size Kids Bike
When it comes to choosing the right size kids bike, our over-riding advice is 'smaller is better than bigger'. Children learn to ride with greater ease, have more control on the bike and have a lot more fun if they are the master of their domain.
Our overall advice on choosing the right size kids' bike is based not only on Age and Height, but Ability and Personal Confidence.
It is all too common to see parents using height as the only key measurement for a bike's correct size. Be careful: it can easily be misleading as an indicator. As most kids' balance develops at roughly the same speed, using age with ability is far more relevant. If you can add age, with height, and ability (ability is a hard one to measure but as a parent you must be honest and realistic) and confidence, than you have a really good indicator.
A bike is the right size when your child can:
- Sit on the saddle and rest the balls of both feet on the ground.
- Straddle the top bar with a comfortable clearance and with both feet flat on the ground.
- Reach the handlebars with a slight bend in the arms when sitting on the seat.
- If there are handbrakes, your child should be able to grasp them and apply enough pressure to stop the bike.
The most common reason kids have to move up a size on a normal bike is because of the lack of knee room between the seat and handlebars. This forces you to put up the seat and then your child loses interest or confidence in riding because the centre of gravity is really high and hence the bike becomes even more difficult to ride.
