Ebikes

The e-Bike (2EBK) roadmap is a level 2 roadmap focusing on specific micromobility solutions (e.g., shared electric scooters, e-bikes). It is situated under the level 1 micromobility system market, representing the broader urban mobility market. Below e-Bikes exists the level 3 roadmaps that target the subsystems within these solutions (e.g., powertrain, connectivity, structural), and level 4 roadmaps delve into individual components (e.g., battery cells, sensors, motors).

Technology Roadmap Overview

Electric bicycles (e-bikes) are a key component of the micromobility revolution, offering electric-assisted cycling at speeds typically below 25 km/h (15 mph). These vehicles represent a significant advancement in urban transportation, providing a flexible and sustainable solution for short to medium-distance travel in city environments. The history of e-bikes traces back to the late 19th century, with early patents for electrically powered bicycles emerging in the 1890s. However, the modern e-bike era truly began in 1989 when Michael Kutter developed the Velocity Commuter, one of the first bikes with pedal-assist technology.

Two iconic e-bikes that represented significant milestones in the development of e-bikes are the Yamaha PAS (1993)- widely considered the first commercially successful e-bike, introducing the revolutionary pedal-assist motor system and the RadRover by Rad Power Bikes (2015)- an iconic model that helped popularize affordable e-bikes for everyday use, making the technology more accessible to consumers.
