The best ideas are born out of necessity. On a 30,000 kilometre bike tour from London to Tokyo, Latvian designer Aigars Lauzis' bike was fully loaded with camping equipment and he had to avoid water - which takes a lot of time and, above all, is a shame. His vision: a bike, boat and camper in one. He developed the first prototype in 2020. His multifunctional tricycle is now in series production.
The BeTriton offers space for one driver and one passenger. It is 3.90 metres long, 1.40 metres wide and 1.70 metres high. A 250 watt electric motor supports the pedals on land up to a speed of 25 kilometres per hour. According to the manufacturer, the conversion from trike to boat only takes a few minutes. The electric outboard motor can be lowered and raised again at the touch of a button. The wheels are folded up and two inflatable floats are attached to the sides. The front section of the trike becomes the stern, the rear section the bow. A foldable anchor is included as standard. With 2.1 kW (3 hp), the BeTriton can reach speeds of up to eight kilometres per hour on the water and does not require a licence. As it is approved as an e-bike, it also does not require a driving licence on the road.
The body consists of a glass and carbon fibre-reinforced plastic over an aluminium frame. The two lithium iron phosphate batteries, each with a storage capacity of 1.44 kWh, can be removed and charged at any standard socket. The total of 2.88 kWh gives the bike a range of around 150 kilometres on land and around 25 kilometres on the water.
The BeTriton can also be converted into a sleeping cabin. The sleeping area measures 2.1 x 0.97 metres and, according to the manufacturer, offers enough space for two people. The cabin can be opened like a convertible, and the seats and plastic windows can be removed. There are two USB ports in the cabin for charging technical devices and another two ports on the front handlebars, e.g. for a navigation device.
The SLIM-Spec starts at €9,950 net and offers an open cabin with PVC cover, a 1.44 kWh battery, a 100 watt solar panel, a 250 watt land motor and a 2,150 watt boat drive. The range is up to 75 kilometres on land and 12.5 kilometres on the water with an unladen weight of around 170 kilograms. The MID-Spec costs 11,950 euros net and adds a lockable hardtop cabin with the same battery and range basis. The kerb weight increases to around 180 kilograms. The TOP-Spec for 14,950 euros net has two batteries with a combined capacity of 2.88 kWh. BeTriton claims a range of up to 200 kilometres on land and 30 kilometres on the water. The unladen weight is around 190 kilograms.
Regardless of the version selected, the standard equipment includes USB ports, a 12-volt socket, interior lighting, navigation lights, an electric motor lift system, inflatable stabilisation floats, storage space, supports, safety rudder and the Carla Cargo drawbar with overrun brake. Extras such as a sleeping mat, electric blanket, mosquito net, table or anchor can be ordered separately.
