Cargo bike has a custom headlight mount protruding from the base of the cargo platform. One side is for clamping a handlebar mounted battery light, other side has a threaded hole tapped into a cap on the tube. I only have the DC lamp connected now but this photo shows both:

Yeah, B&M have two different DC version of the Toplight. One is designed for 6VDC only The other is wide range 6-60VDC Peter White seems to be the only person distributing the second, wide input range version.

I ended up just getting a cheap bar mounted rocker switch which I think was originally designed for motorcycles. Pretty junky and not waterproof as advertised but $7 seems reasonable for the experiment. I'd eventually love to 3-D print a handlebar mount then insert a sealed switch. I tapped...

Hey, I recently built up a Grin Tech kit and will soon be adding a headlight to the bike that runs off the 36V motor battery. I ordered this new Busch + Müller Lumotec IQ-X E which has an input range of 6-60 VDC I was looking at my handlebars today and realized I've been kinda bothered by the...

I also forgot to mention that I have zeroed out the PAS input a couple times and noticed that the zeroing out doesn't seem to be consistent with crank orientation. During unloaded zeroing, rotating left pedal forward vs right pedal forward gives me ~0.1V difference which seems like quite a bit...

I am also having significant issues with my new eBike using the Sempu BB. I noticed similar problems where I am occasionally getting negative Human Watt values. It starts out small at -5W, -40W, -150W and if I stop pedaling it will reset back to zero and when I start spinning again the values...

Yesterday I finished up retrofitting my Cyclefab CycleTruck (originally a Kona Smoke) with a Grin Tech 20" geared motor, Phaserunner, CycleAnalyst, Sempu Torque Sensing Bottom Bracket & 846WH Li-ion Battery. Works great so far and handles better than expected at 20mph which it rarely reached...
