Transition has unveiled the Relay, a 2-in-1 bike that combines a mountain bike and an e-bike. A Fazua Ride60 system can assist you with electric power, and you can detach the motor to ride the bike in analog without the additional weight. The company claims that the bike is much lighter than other e-bikes, though it has not confirmed the exact weight; the full specification will be revealed closer to the Spring 2023 launch.https://www.notebookcheck.net/Transition-Relay-2-in-1-e-bike-revealed-with-Fazua-Ride60-system.630994.0.html
