B&M Toplight Line (6-15volt for E-Bike) Toplight Line is for E Bikes with 6 - 15 volt light power output. For use with 6-15 volt E Bikes, or with Busch & Müller e-bike headlights with taillight connections. Compatible with ALL e-bikes using Bosch or Shimano We love the Busch & Muller Toplight Line rear lights because they are plenty bright to be seen and the built in reflector adds extra visibility. This is the biggest selling rear light for E-Bikes. NOTE: B&M Toplight uses 50mm bolt spacing.
