The BCB Take
The EXR takes a different approach to many electric enduro bikes. Rather than chasing outright power figures alone, Radian has focused on keeping weight low while making the bike genuinely practical, with a removable battery, integrated storage and optional road homologation.
Perhaps the most interesting feature is the adjustable power output. Riders can tune the EXR anywhere from 7 kW to 52 kW through the companion app, effectively changing the bike's character to suit beginners, technical trails or full-power off-road riding. It's a clever idea that could make one motorcycle appeal to a much broader range of riders.
Specifications are based on Radian's announced production targets and may change before customer deliveries begin.
Ride safe, folks.
