BMW ER80 electric
Based on one on the most recognizable engine design and custom trends I chose to look a bit further to an inevitable problem. Eventually we will run out of BMW R type bike from the 70’s to customize as well as the parts to keep them running on the road with combustion engines. Imagine the moment, fossil fuels will be obsolete for everyday transport and your crankshaft wears out. What to do? No more crankshafts around time for an alternative.
In the easiest sense of the concept, pull out the guts take of the cylinders and slam in a 5Kw Electric engine. And continue rolling your custom BMW. But what I would like is that same excitement riding, besides the stance with a to believe silent E-drive. The Experience of riding a custom motorcycle is more than half the fun, an engine shaking, revving s, accelerating and turning heads as you’re strolling around.
Based on our basic 7 sense: taste, movement, balance, smell, vision, touch and hearing. My thoughts on some of these senses are could be linked to certain aspects that make motorcycle riding an experience. Smell of oil and gas, vision of our surrounding going places, touch to textures and heat, movement and balance to speed and handling and hearing as a prime sense to safety since it’s the only sense we have that doesn’t have to place us within direct contact with a situation to have immediate impact (you could say the same for smell but that takes a while). For example someone could drop a mug of coffee around the office corner and you have an instant reaction and idea of what happened. So why make E-drive silent?
Give E-drive the sense of functional sound, the sound to indicate: the engine is on, someone is approaching, acceleration, speed, malfunction (we have all heard the weird ticking noises in our cars at some point). This sound could easily be generated though mechanical principles since it’s nothing else than frequency air displacement.
Next to functional sound the memory and movement handling of a regular bike, instead of a one geared E-drive. Ad a gearbox this keeps the experience of doing something with your machine. As well as lowing the load on the electro motor. Basically 8KW at 10kRPM that could approach 120khp a 4kw engine with gearing to approach 120kph at 5kRPM. Less RPM less Amps needed, less batteries to carry around. It may not be maintenance free implementing a gearbox but adds significant value to riding an electric motorcycle with sound.
