Wondered what happened with you Dan. Glad y’all got out without more injury than PTSD and all the crazy shit work of putting lives back together. So sorry brother….

Re: hub motor problems

Can you feel more thrust above PAS mode when applying throttle? If not, you may just be hitting battery BMS cutoff with the PAS and not when using throttle because maybe your throttle doesn't apply as much throttle signal as PAS does? It's sort of a long shot but easy enough to rule out?

Re: 2 Speed Xiongda hubmotor

An aftermarket mid drive is harder to install and often one has to modify the bike frame. Also they are ugly/very visible. And they cause wear and tear on the drive train. Of course, for really heavy climbing they perform better because they take advantage of the bike's gearing. Don't agree. In fac...

Re: Getting the best chainline with the bbshd

Most of the freewheels I've messed with are built basically like a cassette, in that they have a lockring (that is usually also the smallest cog). Just like with a cassette, you can use two chainwhips to undo the lockring, and then take off whatever cogs you want, respacing them either with rearran...

Holy cow Robo that is a crazy chainline but if it works for you, rock on!

I’m still very pleased using 3 wide range cogs and hardly any angle to the chain.

I personally picked up my Luna 52V 13.5Ah GA cell Shark battery pack from LA on my way through town last week so I didn’t require any shipping.

Re: Bafang Ebrake Sensor

My experience is the Bafang switches use a Hall sensor and pull up HIGH. A little under supply voltage. The CAV3 might be able to handle that signal with some minor setting changes but you would still need to send 5V supply to power them. Myself, when I need the older switch to ground scheme to curr...

Re: 72v on Front Geared Hub Motor?

In theory it all seems doable but in practice you may discover limitations of over volting geared hubs. Remember, majority of geared hub motors were originally designed for 24-36V and as the industry moved to 48V the designs didn’t change much. At least with the smaller geared hubs. My experience ov...

Only 1 cross allows for acceptable nipple angle, IMO. Avoid nipple-to-rim angles much beyond 10 degrees.

Re: Help needed building dummy load device

I recently installed APP’s on AC power strip and then plug whatever AC heaters, clothes irons, toaster ovens, etc. into the power strip. Connect that “load” to power meter and on to battery pack. 50VDC delivers roughly 1/4-1/3 rated AC Wattage. So a 1500W 120VAC space heater will pull about 300-500W...
