The Cateye Rapid Mini is a 15-lumen output, USB-rechargeable rear lamp. Charged via the supplied micro USB cable, it offers up to 30 hours of use (on flashing mode, 3 hours on constant) and features 4 modes of illumination. The need to recharge is indicated by a battery charge-level indicator. For Brompton, this has been designed to attach to the saddle with the supplied bracket [NOTE - only bikes from mid-2016 feature the required thread on the stock saddle. Older bikes may require a saddle upgrade]. This pack includes the lamp, charging cable, bracket and patched screw. The lamp remains fully visible in combination with one of our saddle pouches.
