Triumph TE-1 electric motorcycle prototype

It appears to be a work in progress with lots of cooks in the kitchen:

I really enjoyed this video. It really shows the thinking of Triumph and the creativity of their partners. It's more Energica than Brammo Empulse with the 18 thousand Rpm motor and full CCS charging voltage, limited by battery capacity and C rate. Time with existing products has allowed them to see areas of opportunity for weight reduction and  improvement, product development. Very intergrated motor inverter. I'm excited for them and us....

The videos regarding the TE-1 development are coming thick and fast. Here is the latest (but probably not the last).

Another fascinating video, not expanding much on the previous one. Battery is made of 18650 or 21700 cells like Tesla. A lot of development has gone into using these regarding heating and cooling for use and charging. Reducing losses in the power train and electronics is so important.
Kawasaki ought to be expanding on their prototype this year, it had gears so more Brammo than Energica. I enjoy changing gear but am not sure if the penalties are worth it. Still, it's a road bike!!!

I take my hat off in front of Triumph and all the other entities involved in this project. Inventing and constructing such a beautiful electric motor, which is loaded with the latest technologies, definitely deserves a thumbs up.

I would like to highlight a few things that interested me a lot:
- during the development, they first started by integrating the electric motor, battery and electronics into a newly built frame adapted to the needs of the electric drive, and then the design of the rest of the electric motor is derived from this.
- a very compact liquid-cooled electric motor with an integrated semiconductor-based control unit, with a high power-to-weight ratio and an efficiency of 98.5%.
- two types of battery cells with different chemistry (one type optimized for high energy density, the other for high power) separated from each other by an inverter that optimizes their use (power / range)

I also highly praise the following:
- thanks to the integration of electrical components into larger units, substantial minimization of cabling length
- only single-speed transmission without shifting
- power transmission from the engine to the rear wheel by a toothed belt
- rear suspension almost in a vertical position

The Triumph TE-1's consultant spin is starting to make me dizzy.    https://electricmotorcycles.news/project-triumph-te-1-is-a-collaboration-between-triumph-motorcycles-and-the-uks-electrification-experts/
