The “Tacita® project”, from Tàcita®, Latin name of the Roman goddess of silence, sprang from the desire to develop a motorbike which respects the environment
and the people around us, yet being a true machine for real off-roading.
After twenty years of passion for both recreational and competitive enduro, our goal was to build the perfect electric enduro motorcycle, which would be able to compete with traditional motorcycle combustion engines, giving sensations of pure riding, yet being moved by a completely “no-emission” electric engine.
Tacita® was born in 2009, to produce a new enduro motorcycle with electric propulsion performance, whilst being innovative and unique in its characteristics.
Since then, our effort has focused on research, engineering and design, to create Italian motorcycles with temperament, unique in its kind.
The result are the “T-RACE” and the new “T-CRUISE” : passion, nature, respect, emotions.
Chi sceglie Tacita® sceglie uno stile di vita.
with speed gears
Why the speed gears? In order to have the best gear ratio for every situation, reducing the overheating of the engine and the consumption of electricity. In fact, the lower ratios allow the torque increase, so that the inrush currents decrease, while thanks to the longer gears you will be able to make the most of the engine maximum peak, removing every compromise and keeping the maximum efficiency.
A main point is that the speed gear with an electric engine does not need to shift gear frequently, because when the proper speed for the road is engaged, you can keep it.
Furthermore you are not forced to start with the first gear engaged, as it can be useful for reducing uphill skidding, instead. Speed gears are very useful downhill, because when you engage lower gears, the bike slows down and this allows lesser use of brakes, preventing overheating, enhancing full control of the bike.
You do not need to use the clutch at the start, because when the electrical system is on and the accelerator is released, the electric motor does not rotate (unlike the internal combustion engine) so the bike does not move, which is why it is not necessary to≤ pull the clutch when you stop. The clutch is then used to reduce the torque, when necessary, and to change gear.
On the electric motorcycles, batteries deliver current, which goes to the controller and is converted into alternating current. According to the technical standard IEC 60479-1, the minimum voltage that is considered to be dangerous is 120 V;
In order to not exceed this safety limitation, not only we have chosen that the total voltage of our batteries is less than 120 V, but we also divided them into two completely autonomous parcels, each of them with a voltage lower than 60 V (Regulation ECE No.100).
