How does it work?

Step 1: Screw your mount into the hole in the steering column of your sportbike.

Step 2: Protect your phone in the sleeve or glue the adhesive steel plate to your phone shell.

Step 3: Snap the sleeve or metal plate into place, centering it on the mount. And there you go: your phone won't budge.

Does it hold?

Yes, it does. And it's holding strong!

But rather than a long speech, here are a few important points:

  • Paving stones, potholes, sidewalks... the mount holds!
  • Stable even at high speeds (tested up to 225km/h on circuit)
  • The magnetic system supports up to 50 times the weight of your smartphone.
  • The system has been validated by over 5,000 stores.

And you can imagine that, for the past 5 years, if our mounts didn't work, we wouldn't be here anymore, and the best chains wouldn't sell us.

To approve our motorcycle's mount, we did two tests:

- the first in a wind tunnel at nearly 140km/h (maximum wind tunnel speed) with the LIFSE.

- a second test on the Carole circuit at 225km/h.

1. Choose the right adapter and nut for your steering column diameter: 

  • 11 to 13.9 mm steering column: 11 mm adapter and 11 mm nut.
  • 14 to 16.9 mm steering column: 14 mm adapter and 11 mm nut.
  • 17 to 22 mm steering column: 17 mm adapter and 14 mm nut.

2. Place the mount in the steering column and screw it sufficiently with the key hex to make it almost impossible to remove the mount by hand.

3. Assemble the Booster 360 by replacing the screw, and adjust it to your convenienve by screwing the 3 screws on the orientation axes, until the Booster can no longer move.

4. Insert your phone into the sleeve, snap it to the mount (making sure it's centered) and off you go!

Reviews of those who tested it


Reviews of those who tested it


Because we could tell you what we want, the best reviews are still coming from those who have tested it!

Do you still have questions?

Are magnets dangerous for my phone?

No. Simply because there is no magnetic field in the sleeve or through the plate. We explain it all here.

Just think, brands like Apple now even put magnets inside the phone.

I saw that the mounts could break the phone's camera?

This is true only for motorcycles, where the engine vibrations of certain bikes can damage the optical stabilizers of certain phones (mainly Iphone).
Our mounts with sleeve absorb the vibrations, so there's no risk.

We explain it all here.

Can someone steal my phone?

It's a legitimate question, but it's not a concern we're seeing at all.
On the one hand, you have to bear in mind that the mount is removable. Our mounts are very discreet, with no apparent distinctive sign. There's no more risk than when you're walking down the street with your phone in your hand.
Most snatch thefts take place on public transport. In the subway, for example, where once the doors are closed, there's nothing you can do about it.
Once again, this is a legitimate question, but we haven't had the slightest feedback on this type of theft.

Is the sleeve tactile?

Yes, of course. And to ensure that the touch is as responsive as possible, it's important to choose the right size of sleeve, for which please refer to our size guide.

Does the sleeve really protect against the rain?

The Classic and Pro sleevees provide protection from the rain, but are not designed to be immersed in water - they are not waterproof. For this, you need to choose the waterproof sleeve.
But under normal conditions, you can ride in the rain without worry with our 3 sleevees.

Does the phone heat up?

Obviously, the phone will heat up more in the sleeve than without it. Then it all depends on the phone, the GPS, whether you're charging the phone at the same time, and the outside temperature.
It's rare, but it can happen. In this case, you should opt for the version with the metal plate.

Are there reflections in the sun?

Yes, it can happen. Depending on the position of the sun, the position of your phone or your posture on your 2-wheeler. You can use the metal plate to limit this effect, but don't forget that, even without a pocket, visibility can be reduced in direct sunlight.
And don't forget to set the brightness of your screen to maximum.

Can I charge my phone?

Yes, of course! The Classic and Pro sleevees have a slot for the charger cable.

What if I change my smartphone?

If you stay with the same size, you don't have to buy anything. If not, you can buy just the sleeve, no need to buy the whole again.

Is there a warranty?

Yes, up to 10 years by registering your product. All explained here.

Is it compatible with induction and/or Magsafe charging?

The metal plate is not compatible with induction charging.

The Magsafe won't be enough to withstand the shocks. It is essential to use the Shapeheart sleeve or plate to ensure proper use of the mounts.

Which version to choose?

It's all explained : here.

Sylvain G.
iPhone13 + MP3 maxi-scooter

Great product, 3rd purchase!
Already tested on a motorcycle and for my son on a 50 scooter (on a rear-view mirror stem).
The maxi-scooter kit works perfectly on a 2020 Piaggio MP3, with mounting under the glove box. Very sturdy.
Highly recommended.

xiaomi redmi note 9 pro + motorcycle kawasaki ninja 650 (10/2023)

Very simple installation, fits perfectly. First impression of materials: qualitative.
I haven't tried it on the road yet, but don't worry, the magnet is very powerful. The standard and waterproof pockets are very good. The touchscreen works perfectly. The phone needs to be set to landscape mode to see the speedometer. I'd recommend it.

Excellent, I highly recommend

I've been using it for 1 month now on damaged roads and it doesn't move on freeways. I highly recommend it.
