Safe, comfy and perfect for everyday use – that’s how Britax has labelled its Römer Jockey Pro. I put the child bicycle seat to the test.
My three-year-old granddaughter Leia is still too young to ride a bike with pedals and gets tired quickly on her balance bike. So for longer bike rides with Granddad or Mum, she needs a child bike seat. Britax provided me with the Römer Jockey Pro for testing purposes.
Unboxing and first impressions
As I unpack the box, I already feel good about it. There’s the child seat, a frame mount and the seatbelt pads. Instructions are also included. That’s all I need to get started.
The seat measures 72 × 44 × 43 centimetres and weighs 5.1 kilogrammes. Its size makes it look sturdy without being clunky.
But before you buy, it’s worth taking a quick look at your bike. According to the manufacturer, the Jockey Pro is approved for round frames with a diameter of 28 to 40 millimetres. You’ll need 80 millimetres of free space on your bike frame for installation. The wheel size should also be between 26 and 28 inches. On e-bikes, the seat is only permitted to be installed if the motor assistance cuts out at a maximum speed of 25 km/h. It’s not suitable for bicycles with rear suspension, carbon frames, nor for folding bikes, mopeds, scooters, or other motorised two-wheel vehicles.
The seat is designed for children aged nine months to six years. Needless to say, your child should be able to hold their head up on their own and will need a helmet that fits.
Installation
The step-by-step instructions are easy to follow and guide me through the assembly process. Fortunately, my bike meets the necessary requirements. First, I attach the bracket, which will later hold the seat, to the seat tube using four Allen screws. Nothing’s attached to the luggage rack. The manufacturer states that this type of mounting increases the comfort for the child. This means, unlike other models, this mounting system doesn’t transmit shocks and vibrations to the seat via the rack.
And yet, the installation isn’t particularly straightforward in my case. This has less to do with the seat itself and more with the shape of my bike and the fact that Leia sits very low. This combination makes attaching the mount to the seat tube harder than I’d hoped for. If your bike doesn’t provide much space, you’ll need a little patience to get everything to fit just right.
Once the seat is securely installed, it looks sturdy to me.
Taking the Jockey Pro for a spin
In a practical test like this, it’s also important to consider if the child likes the seat. If they enjoy sitting in it and getting them in is stress-free, it saves everyone involved a lot of hassle. Leia likes the look of the seat and says she finds it comfortable. From an adult’s perspective, she’s sitting securely, too.
I like the adjustable footrests. They make sure Leia’s feet don’t get caught in the spokes. This means there’s less for me to worry about while I’m cycling. The seat material also seems practical. It’s designed to be water-repellent so your child doesn’t arrive with a wet bottom if it’s been raining. Ironically, a heavy downpour has yet to materialise during my test in northern Germany. So it’s hard for me to judge how well the seat would fare in the rain, even though the material should be able to withstand it.
In terms of cycling, the seat doesn’t bother me. The bike rides well even with the child seat attached. With three children of my own, I know what it’s like to ride a bike with a child seat and don’t feel any difference to other seats. However, back then those seats were attached to the luggage rack and rattled on the cobblestones that were common in my town. The Jockey Pro doesn’t.
I need a new bike stand
A child seat changes the centre of gravity of your bike. In my case, my bike now tips over more easily. This means, your child should only be put in the Jockey if you’re holding the bike with one hand. Depending on the surface, I find it a bit difficult to buckle up Leia, as my bike tends to slip away. However, a solution’s on the horizon. With a two-legged stand, that shouldn’t happen anymore.
Regarding the seat’s safety in the strictest sense, I can’t comment on that in this practical test. In 2025, consumer magazine «Stiftung Warentest» gave the seat the rating «good» in the category «safety». My impression after using it regularly confirms this. The seat feels sturdy, the straps appear to be well-made and the footrest mentioned earlier also contributes to safety.
If you want to use the seat on your own bike as well on other family members’ bikes, it’s a good idea to get additional mounts. All you need to do is attach the mounts to the respective bikes for a quick and easy seat swap.
In a nutshell
A solid child bike seat
Britax Römer Jockey Pro review: a sturdy seat, but a bit of a hassle to install The seat ticks all the boxes when it comes to finish and ease of use. In other words, your child will be comfy and safe. One weak point, however, is its assembly. Although the instructions are clear, installation can be a bit fiddly depending on your bike and riding position. If there isn’t much space on your bike frame, you’ll need a little patience.
