The lightest electric bike in the world looks like a normal bike: the trick is in the “water bottle” which is not such
At first glance it looks like a normal bicycle, but inside it hides a small electric motor. The new one HPS Domestique is the lightest electric bike, weighing only 8.5 kilograms. This bicycle is the creation of the HPS brand, based in Monaco, and its cost is not exactly cheap. In return we have a bicycle built with German and Swiss components where the design has been taken care of in detail.
Where is the motor and battery hiding? The first component is hidden in the bike’s seat tube. We have a little 200 watt motor and maximum torque of 20 Nm. This engine, designed by the professional cyclist Phil Deignan, is in the lower tube of the frame and although it is not among the most powerful, it is enough to provide up to six levels of pedaling assistance.
A camouflaged battery in the shape of a water bottle
The engine is not visible from the outside, but the HPS Domestique also hides the battery. The usual thing is that many designer bikes what they do is increase the thickness of the down tube, but this is not the case. The carbon frame of the HPS Domestique has a tube with a standard thickness and weight, being for all purposes like a normal bicycle.
The solution is quite ingenious: the “water bottle” is actually the battery. It is a 193 Wh battery that promises up to 3 hours of autonomy. The company calls the bicycle system the ‘Watt Assist System’ and the goal is to replicate the weight of normal bikes. East system, patented by HPS, lets the wheel free when the motor is not assisting pedaling. A mechanism that allows a smoother pedaling.
To recharge the battery, the company promises that we will be able to do it in two hours. We do not have data regarding the autonomy in kilometers, but taking into account its size, we would be around 100 kilometers. Its maximum speed is limited, by European legislation, to 25 km / h.
With a body completely made of carbon, the electrical system only contributes 1.5 kilograms compared to the total 8.5 kg. A minimum weight that integrates completely with the body of the bike, by posing as what it is not.
The HPS Domestique is a high-end bike and as such adds Pirelli P Zero rubbers, Deda Elementi handlebars and a design made to measure by Campagnolo, one of the most experienced companies.
The lightest commercial electric bike sold in Europe at an official price of 12,000 euros. Additionally, HPS offers a smaller 85 Wh battery for flight use and recharges in one hour.
