Do you know what the most common type of electrified vehicle in the world is? It’s the electric bike. Quite possibly they are the most common solution right now to the ‘last mile’ problem where once you have got to your work city you still need to get to work somehow. With an ebike you can zip along the street like any normal bike without worrying about getting all sweaty in your work clothes.
But electric bikes don’t come cheap which is why many people turn to home conversion kits. With them, one can take that cobweb covered bike from the back of the garage, give it a wash down and a new lease of life thanks to some batteries and an electric motor.
But may of these kits make using the bike feel heavy, especially once the batteries have run out. Enter Velogical with their Velospeeder rear rim bicycle motor system. This is set to be, when it is released early next year, the lightest and smallest conversion kit available..
Weighing just 1.6kg the twin electric motors pit out a combined 600 watts of power and 40Nm (29.5 poundfeet) of torque. The current prototype uses a 92Wh (yes, Watthour) battery that provides around 12.4 miles (12.4km) of electronically assisted travel.
Velogical say that the battery is light enough that a spare can be carried when travelling.
The current prototype has been used for a total of 2485 miles (4000km) and tested in all conditions. The two motors in the kit are intelligent enough to alter their position to ensure they both contact that bike’s rim at the same time to provide a smooth transition from human-power to electrically assisted. You can see the system working in the clip below:
Velogical plans to offer their kit to bicycle manufactures and bike shops for retrofitting. Currently they have no plans to sell directly to the public.
