If you're searching for an easy way to convert your bike into an e-bike, try this kit from Swytch. Featuring a motorized front wheel producing 250W of power as well as frame-mounted battery and cadence sensor components.
The system utilizes a cadence-controlled motor that complements but doesn't replace pedaling action for a more natural ride experience than torque-controlled systems.
Upgraded versions can feature up to two additional batteries for enhanced speed and range capabilities.
