Re: Does this look safe?

I wouldn't. Plenty of LED ebike headlights out there that will run on 60V or more. Also this is a Cree LED headlamp. The paperwork shows 10-80volts But the first one I connected straight to the battery and I believe it fried the diode or something. I didn’t smell anything but the light won’t turn o...

Re: Anyone else here feel guilty?

No, but with 200W (no speed limit) Au legislation and a loaded trailer I am not setting any speed records. On electrical power only it barely reaches 25kph, I cruise at 28-32kph with cut-off just below my cruising pace and generally don't exceed 35kph by much because of the trailer. At that pace ele...

Re: First Ebike: Too much Battery ?

Battery is fine, the controller is a bit of a worry without limits. I wouldn't run my 311s at more than 5A (at 52V) without thermal roll back. I suggest 10-12A maximum with roll back. They heat up quickly. I limit mine to 80C which is on the low end of the spectrum... definitely wouldn't want it exc...

Re: DIY Phaserunner heatsink.

Maybe. My policy is to keep electronics as cool as reasonably possible regardless of maximum design operating temperatures. Heat is the enemy. Even my lowly baserunner limited to 250W is mounted on about 400mm of 3mm aluminium bar (I needed an L bracket) that acts as heat sink on its own, plus has a...

Re: An alternative to torque and rpm pedal assist

I use a Grin Aux pot with 1K resistor as my throttle. Throttle is power, could also be amps. On drop bars I roll it with a forefinger, on flat bars it can be rolled with a thumb. Takes a little getting used to, but it works. It stays where I set it. Also 6kph minimum, 50rpm minimum and ebrake cut of...

Re: Well I got my first flat in a long time with an extra present

Tubliss in my motorcycles prevents pinch flats and a lot of rim damage, allows low pressures and tubless on tube type rims. cSchwalbe ProCore with half a bottle of sealant is the same thing for MTBs.

Something to be said for low power and lightweight systems. Power and weight especially the battery spirals out of control fairly quickly.
