The TTX01 is the most advanced emission-free bike on the verge of commercial production: it is already road-legal in the UK and its makers claim it can go from 0-60mph in 3.5 seconds, eventually reaching a top speed 125mph. A limited number will go on sale at the end of next year at a price of £20,000.
The only other electric bikes close to to commercial production are the American company Brammo’s Enertia, due to hit the market next year, and the Vectrix scooter. But, since both of these are aimed at the commuter market, they have significantly smaller motors and top speeds — 50mph and 60mph respectively — than the TTX01.
The TTX01 runs on two battery-powered electric motors, each weighing 11kg and designed by Brighton-based Agni motors, attached to its rear wheel. It is rated at around 86 break horse power, equivalent to a the peak power of a standard 600CC racing bike. On a full charge and at a moderate speed, the bike’s 75kg battery will currently allow it to travel around 50 miles. Using a standard 13-amp electric socket, the battery can be recharged in under two hours.
