Did you have to bring the bike into the shop to have them to program the bike for the light that you mentioned in the video? I just bought a Powerfly FS 4 Gen 3 and am looking for a light myself. Great informative video, thanks.
@@nomaddict5279 Thanks for the reply. Thinking more about this, I think I will go with the separate battery version, less confusing, wiring, and its brighter as you say.
The light I used in this video (MagicShine MJ906S) actually pulls too many amps on its highest setting. It has an Ebike mode that works great though. To get the light into this mode, hold the power button for eight seconds until it blinks red. Do NOT put the light on its highest output mode without doing this FIRST or it will cause an error on the Bosch computer screen and you will then have to wire the light to another battery source that can handle the high amps long enough to let you switch to the ebike mode (which is what I had to do). The light is extremely bright on the highest mode when not in E bike mode, so if you have a battery that can handle the higher amps, you will be amazed at the output. It still seems decently bright on the highest E bike mode.
@nomaddict5279 I’ve just bought a trek rail 9.5 gen 2 a few days ago, is this light worth buying or should I get a slightly less powerful one? Also want to make sure.. are you saying the light cannot be used in its highest power on your bike? If so.. do you know if there’s a light that the bike can handle better?
@@skullxsmasherz3548 it’s plenty bright for me in the E bike mode, and it seems to be really well-made, so I am happy with the purchase. I read where some people have wired directly into the Bosch battery to get past the electrical limitations of the factory wiring/computer, but I’m sure that voids the warranty. I think it puts out around 2800 lumens in the highest E bike mode, which is totally fine for me. I was getting by on 1300 lumens before I bought this (and 1300 lumens on my helmet), and I ride 10 to 15mph comfortably on singletrack trails in pitch black, so this is even better. The 4500 lumen output is for the highest non-ebike mode. It would be nice to use that mode, but I’m not too disappointed. I’m mostly glad to have something directly wired into the bike and this puts out about as many lumens as you will find on any light that will work with this bike. When you take it to the dealer to have the computer programmed to use a light, they will be able to set it to always on, or not always on. Tell them to use the not always on mode. otherwise the light is on even during the daytime, and you cannot turn it off with the button on the light.
@@skullxsmasherz3548 also, in the highest E bike mode, which is 2800 lm I believe, it pulls about 15W. Whatever watt number you tell them determines how much battery reserve the bike keeps for pedal assist versus headlght power (it’s designed to leave you some battery for your light so you can at least pedal home, versus draining the battery with pedal assist and not having a headlight).
@@skullxsmasherz3548 hey awesome!! I think you’ll really like it! Just be sure to hold down the button for 8 seconds to get it into ebike mode before you accidentally put it on non-ebike high mode like I did! :)

Yes, I did have to take it to the shop to get them to enable the light that I installed.

@@nomaddict5279thanks for the help I ordered the light and it came a couple of days ago, I haven’t installed it yet but will get it done asap👍
