Ribble’s Endurance SL e model already held the title for lightest electric road bike, which weighed in at a claimed 25.3lb (11.5kg). But the new Hero edition of the bike, which comes spec’d with Shimano Di2 and new superlight carbon wheels, is slimmed down to 23.08lb (10.49kg). That’s a new high-water mark (or, rather, a low-water mark) for superlight electric road bikes. Both weights are based on a medium frame, according to
Ribble.
