More Info

Lumicycle‘s 2020 Extender range offers outstanding performance in an incredibly small form factor. Housed in extremely durable lightweight carbon fibre tubing and assembled with custom UV stabilised, soft, flexible and extremely strong polymer end caps.

Extender 6.8ah Li-Ion batteries are likely to replace our original bag battery as the most popular option to power all of our light systems. The tough Codura bag offers good weather resistance and is very hard wearing, and allows the battery to be mounted anywhere on the bike frame. The end caps are flexible to allow for any mount location, onto any frame shape or size. Two velcro straps secure the battery to the bike. The battery is supplied with 2 leads, one of which can be tucked into the bag if not required.



The table below shows an estimated run time in each mode using the Carbon Extender 6.8Ah battery, assuming constant power mode use, without the automated battery management software, that will increase the run times in Mid, Low and strobe modes by around 30% from the times published here. Older Halogen and Halide lights only have one run mode, with no additional run time extending software.  Many factors impact actual run times, initial charge state, ambient temperature and the version of LED driver board and software will all have an influence on actual runtime, these times are conservative but should be used a a guide only.


if you have a requirement for specific runtimes please contact us to discuss as we offer special versions of software for extreme run times for Ultra Endurance and Audax riding.
