Electric Motorcycle Concept
Electric bikes are an up and coming approach to the electric vehicle industry. Most concepts in development and on the market today essentially replace the combustion engine with batteries and a motor, using a variant on the legacy chain transmission in most cases.
The concept, tentatively being called the WASP is intended to be a performance bike, with strong performance and range. Non conventional approaches to design will be obvious as the design matures.
Starting up with a new concept for an Electric Bike, we started by breaking the mold a bit. A rough CAD rendering below shows the rear powertrain, reserving the body exclusively for battery power and control.
What jumps out, of course is the hub-less concept, eliminating some rotating mass. A series of smaller motors are mounted to the rim, directly driving the wheel. This will increase the unsprung mass, but it is felt it can be compensated for with proper selection of the shock and spring. The hubless concept offers its own unique challenges as well.
