All about the Stern'

Three wheels, a battery in the backpack

The Stern' is a three-wheel all-terrain electric skateboard, with the motor built into the rear wheel and IP67 waterproofing. On most configurations, the battery is carried in a backpack and connects with a single clip: the board stays light and the battery is protected from knocks and vibration. Designed and assembled in France, the Stern' comes with the 2-year legal guarantee of conformity on the whole product.

Why three wheels? Édouard's first prototype had four, and he was disappointed with how it performed. By combining the skateboard and the electric unicycle, Édouard and Adrien developed the three-wheel model, which became the brand's signature.

Choosing your Stern' by range

The range has four levels of range: 20, 50, 75 and 100 km. Each one comes with a 1000 W or 2000 W motor, to choose on the model page.

Urban, integrated battery

The battery sits directly inside the deck: no backpack, up to 20 km of range for everyday journeys in town. Available in 1000 W and 2000 W. See the Stern' Urban page.

50 km, 15 Ah backpack battery

15 Ah backpack battery, up to 50 km of range, charges in 1.5 hours with the 10 A fast charger. In 1000 W or 2000 W. See the Stern' 50 km page.

75 km, 20 Ah backpack battery

The middle of the range: 20 Ah backpack battery, up to 75 km of range, charges in 2 hours. In 1000 W or 2000 W. See the Stern' 75 km page.

100 km, 25 Ah backpack battery

Frequently asked questions

Is the Stern' waterproof?

Yes, it is even submersible. The integrated battery is protected against rain, splashes and puddles.

Does the Stern' need much maintenance?

No, it is very simple: mostly a rinse with a hose. From time to time, check a few screws and put some WD-40 in the bearings and the suspension. That's all.

Does the Stern' comply with French regulations?

Yes, straight out of the box: front light, red rear light, reflectors, horn, and speed limited to 25 km/h. Legal category: EDPM (engin de déplacement personnel motorisé), the French category for powered personal transporters.

Does it need insurance, and how much does it cost?

Yes, like any electric vehicle: between €3 and €4 per month. Insurers now know the Stern', and we can provide you with a certificate of conformity to send them.

What are its main technical specifications?

Three wheels, a 1000 W or 2000 W brushless motor built into the rear wheel, IP67 waterproofing (the board is submersible) and a 14-ply wooden deck in bamboo and Canadian maple. The Stern' weighs 17 kg without the backpack battery (20 kg for the Stern' Urban, integrated battery included), takes up to 120 kg and can be adjusted from the app.

What is the difference between the 1000 W and the 2000 W motor?

The 1000 W is enough in town and on flat ground, for everyday journeys. The 2000 W climbs gradients of up to 35%: it is better suited to riders over 90 kg and to those who want maximum power. In both cases, the brushless motor is built into the rear wheel. It all depends on your terrain: mostly city, or mostly off-road.

What is carving?

It means turning by tilting the board, as on a snowboard: long, fluid curves and a real feeling of gliding. With its three wheels, the Stern' carves on every terrain, even on tarmac. The stance is natural and quick to find.

What terrain can you ride on?

Almost anywhere, thanks to the three wheels and IP67 waterproofing: in town (tarmac, cobbles), at the beach (sand, salt water), in the forest (muddy paths, streams), in the mountains (rocky ground, gradients up to 35% with the 2000 W motor) and on snow with the Snow Kit (track and skis). Enough to ride all year round.

Is the Stern' reliable in tough conditions?

Yes. The Stern' has been developed and tested since 2019. Its technical choices (three wheels, battery in a backpack, IP67 waterproofing) are aimed at durability and minimal maintenance. Rental companies and professionals use it intensively, in all conditions, over thousands of kilometres.

Can the Stern' be adapted to your needs?

Yes. You choose the battery according to the range you want, then accessories according to your terrain: track and skis for snow, track only for very soft sand. In the app, you adjust your board, with speed limited to 25 km/h for riding on public roads.
