1. Light can range from 2000-6000+ Lumens (depending on the mode). Wanted to give users options in case they did off road in the dark. It is with a manufacturer that has started to produce some incredible (and super well reviewed) high power lights. We are testing 2-3 variations right now, and I will have a better answer on the final choice in a few weeks. The construction is world class, they have local US presence, and the warranty etc is fantastic. On par with Supernova. Oh.. and you can actually turn the light OFF explicitely (since it is not euro spec).
2. GPS is a custom unit for Watt Wagons, certified for ATT style networks. The coverage is exceptional - you can still track quite well even in super remote areas. Technically any unit that is the right size, that has been certified for ATT can be used. We have something custom that has excellent performance, has a battery backup, great warranty, and a few more core changes to allow for dual charging, heartbeats, etc etc.
Question. for everyone :
For high power (20W-80W) lights, these can be wired to the ebike battery. However at 70 / 80W they use a significant amount of energy and can materially affect the range. I would recommend using a slim dedicated battery pack to power these. The battery pack is slim and can be mounted on the frame or under the lights. The battery pack can be charged from the DPC18 display. So you are technically never out of power.
Thoughts on choice of wired versus battery powered high power lights?
