The Cortina E-U4 family transport is the perfect bike for parents who travel with children and want to transport their belongings safely at the same time.
Thanks to the extended frame, this bike offers extra space between the saddle and the handlebars, so that both mom and dad (or grandpa, grandma or the babysitter) can cycle comfortably and safely.
The handlebar lock and double stand provide extra stability, even with children and luggage on board.
With a load capacity of 170 kg, the E-U4 offers enough capacity to carry groceries, diaper bags and other necessities, without compromising on safety or comfort.
Cortina understands that comfort is essential for parents who often make long journeys, and has designed the bike with these needs in mind. The E-U4 is available in various unisex colours and makes cycling with children not only easier, but also more fun.
This bike comes standard with a 400wh Bosch battery and a 2a Bosch battery charger. An optional upgrade is possible to a 500wh battery so you can cycle even further.
The battery charger can also be upgraded to a 4a battery charger so you can get on the bike even faster!

Children are generally taught to ride a bike at an early age.
The right size bicycle allows for a comfortable and safe riding position for children and teens, and stimulates maximum performance of the muscles.
Aside from being less tiring and preventing overexertion of the knees, the right size bike encourages regular bike use and cycling in general.
This size is usually based on the wheel diameter.

This sizing chart for children's bicycles is based on age and length.
Not everyone is the same length at a certain age, so it’s advisable to determine the bicycle size based on length.
The most important factor in determining the right bike size, is the inseam length.
Body Length | Inseam Length | Recommended Bike Size |
||
120 - 140 cm | <52 cm | 16 inch | ||
52 - 74 cm | 20 inch | |||
> 74 cm | 24 inch | |||
140 - 160 cm | < 62 cm | 20 inch | ||
62 - 80 cm | 24 inch | |||
> 80 cm | 26 inch | |||
> 160 cm | < 74 cm | 24 inch | ||
> 74 cm | 26 inch |
Most children that are 120 to 140 cm tall can ride a 20 inch bike, while children between 140 and 160 cm tall can ride a 24 inch bike.
A 26 inch bike is generally suitable for teenagers who are over 160 cm tall.
The right frame height is also very important: it is the first step to finding the correct riding position.
A bicycle frame that is too small or too large can lead to limited height adjustment options, which in turn may lead to an inconvenient height difference between the saddle and handlebars.
Use the inseam length to determine which frame size is right for you.
You can do this by measuring the inside of your leg, from the top of the thigh down to the floor.

Cortina hit the market in the 1970s with a reliable range of city bikes and stands for quality, no-nonsense and reliability.
In 2006 Cortina began marketing itself as a true experience brand and by closely following market trends and developments, it was able to come up with a range of trendy lifestyle bikes, combining design, comfort, quality and affordability.
Although the first years did prove difficult, Cortina achieved true success with its 2008 collection, when it introduced the Cortina mothers bicycle and its accessories.
The following year Cortina really hit the jackpot with the Cortina Transport U4.
Cortina’s success continued in 2010 and today it is one of the fastest growing bicycle brands in the country.
In 2012 Cortina started a fashion campaign, collaborating with designer Michael Barnaart van Bergen.
Just like the clothing you wear, your bicycle is an expression of who you are.
Barnaat van Bergen designed five outfits inspired by the 2013 bicycle collection and a contest was held to find five models to be the new face of Cortina.
The brand plans to continue their fashion campaign next year.
Today Cortina has three product lines with various models:
- Originals: authentic bicycles with a retro look
- Utility: modern transport bikes
- Metropole: sporty urban bicycles
Your Cortina, your style.
