Thule knows that every family is different and has different needs, that’s why their new stroller – Thule Sleek grows with the family and adjust to its changing needs. Parents can use many seating options and create their own Thule Sleek just like they want.

Toddler seat

In the basic set this stroller comes with regular toddler seat which is reversible and equipped with 3-position recline. There is a flat position which according to manufacturer is suitable for newborns. However it is still few degrees reclined so I’d guess you will need an additional insert or body pillow for proper support for your newborn. Great thing is that the recline is one-handed, there is a lever on the back of the seat which you need to use to lower or raise it.

What I really like about this stroller is the upright position – it’s pretty up, which is perfect for curious toddler. Such a straight upright position is really rare, especially among everyday strollers. Big plus for Thule Sleek!

There is also a leg rest that can be adjusted separately, as the baby grows. Very useful feature. The seat is equipped with comfy and soft padding that is completely removable and washable. There is also adjustable 5-point harness with padded straps. The is also bumper bar that can be open from either side so parents can have easy access to their baby.

The regular seat has capacity of 48.5 lbs, while the second seat has weight limit of 33 lbs. On many websites you can find incorrect information that both seat have capacity of 75 lbs (and 150 lbs of total capacity). The brand lately confirmed the weight limit of 48.5 lbs and 33 lbs, for the regular and sibling seat respectively.


There is also option of attaching a bassinet to the stroller frame, so parents can make it suitable for their newborn baby. The canopy and apron protects infant from the sun and wind. The sunshade is adjustable, has sun visor and mesh part which opens with a zipper. The weight limit for bassinet is 19.5 lbs. It will be available in 5 color versions: red, black, navy, grey mélange and dark grey.

Infant car seat

Thule understands that urban parents often drive with their kids and know that car seat compatibility is a must-have in a stroller. That’s why the new Thule Sleek can be also turned into a travel system as it is compatible with infant car seats. Sleek can accommodate two infant car seats, you just need to purchase special adapters separately.

Options for two kids

Parents can expand Thule Sleek to a double tandem stroller and add another toddler seat or infant car seat. It perfect option for parents of twins or parents who plan on having second child shortly after the first one.

I love the fact that this stroller comes with upper seat adapters, so you don’t have to spend extra money on this accessory!

Oh and there’s one more thing. When you convert this stroller to a double the upper seat goes even more up and it’s really close to the parent. It’s really great features, especially if you have two kids of different age, because you can keep your youngest one closer to you. It also helps you to interact and bond with your baby. And thanks to awesome design you don’t have to worry this upper seat canopy will cover the handlebar and make pushing more difficult.

As you can see this stroller really grows with the baby and adjust to expanding family. Parents can start using it since birth with a bassinet or infant car seat. As the baby grows and develops neck and head control, you can change it for a regular, toddler seat. And when you’re expecting your second child, you can add infant car seat or second toddler seat.

Option for third child

You can also add a board for the third, older child where he can stand during the stroll. It’s great option if you have also a preschooler.


The regular seat has good-sized canopy with a sun visor. Thanks to it your child will be protected from sun, wind and rain, while being also protected from overheating since there is a rear zippered mesh part of the canopy. The sun visor can be folded away or unzipped when not in use.

There is also silent peek-a-boo window with magnetic closure so you can easily check on your baby during strolling without waking him up.

Great thing about this canopy is that you can slide it up as the baby gets taller, giving your baby even more room to grow.


The handlebar can be adjusted to different heights to provide comfortable pushing for shorter and taller parents. There is 8.5 inches of adjustability. The push bar telescopes in and out which is awesome because it gives taller parents more space behind the stroller so they don’t kick the rear axle and wheels.

Wheels & Suspension

Thule Sleek wheels are filled with foam, durable and resistant to abrasion.

Front wheels are pivoting to make the stroller more nimble and easier to maneuver even in tight turns and even with two kids. Parents can also lock them to increase stability when they are going over rougher terrain, like gravel or grass.

The wheels have one more awesome feature: they have a reflective inner part to keep you and your baby visible and safe during morning or evening strolls.

Each wheel has independent suspension which provides comfortable ride, even when going over cobbled street or gravel.


It has single action brake, placed in the middle of the rear axle. The pedal it quite big which makes it easy to press and lift.

Storage space

Thule Sleek offer really nice storage basket under the seat. This bin closes with a zipper to protect your belongings from falling out or from the rain. Besides, when you fold the stroller, you stuff won’t fall out! And even when the basket is zipped, you have the quick access to it because the rear part extends and closes with magnets. It’s really smart solution, that you don’t have to unzip the basket to take out your gear. This bin can hold about 11 lbs.

And if this basket is not enough for your gear, you can always add another storage bag and attach it to the stroller frame, right behind the basket.

Size & Weight

Usually tandem double strollers are heavy and long which makes them hard lift and difficult to steer. With expandable stroller it’s different, these type of strollers is much shorter, because the frame has the same size in single and double version. Thule Sleek is an example of that.

It’s not long, so parents can easily push and turn it. Going over curbs or putting it to the car trunk won’t be a problem because this buggy is pretty light! It weighs about 27 lbs which is still amazing for such a multi-functional and convertible stroller.

The chassis is really lightweight, as it is made of aluminum. So the stroller is pretty easy to carry, especially when the seat is detached.


To fold the stroller you just need to pull two triggers placed on both sides of the handlebar and it collapses immediately. It’s very easy to do, takes few seconds and the stroller after folding is quite compact. What’s really great is that you can fold it with or without the seat attached. However, keep in mind that the stroller is easier to transport and store when the seat is detached.

Best application of Thule Sleek 2018

This stroller is design for city dwellers who want to share their urban excursions with their kids. It’s perfect option for parents who have one child, but plan on having second baby soon or already have two kids. The stroller has nice balance so it can be used not only for twins, but also for a newborn and older toddler.

Thanks to wonderful wheels and suspension this stroller can handle many types of terrain. And with nicely padded reclining seat and good-sized canopy it’s super comfortable for the child.
