Re: My econo-e-bike

I suppose a better way to think of the LVC is just like the charger does Constant Current, then Constant Voltage while charging the battery. The motor controller discharges the battery at a constant current until the LVC, then it discharges at a constant voltage.

Re: bluetooth BMS?

I'd say go for it. I know from measuring my hub's hall sensors that each of the 3 wires just cycles between 5 and 0 volts. If you can measure that coming out of the sensor, then you're golden.

Re: StefEbike for my wonderful disabled wife

Been doing some nice biking, for me anyways. It's not daily like some people, but it's what I can get away with, raising kids, back to working 40 hours a week and all. Annual Des Plains River trail, ended up being 47 miles this time looping around Independence Grove forest preserve. I'm going to mak...

Re: Schwalbe Super Moto-X Tires

Nice pictures! I have one in 20" form on the front of my recumbent. Recently moved it from an Alex DM24 wheel (24mm inside width) to a 29mm inside width wheel, which to me helps with such a wide tire.

Can you probe the voltage between BC29 and BC30 on the board please? Also between BC0 and BC1 while you're at it.

Re: My econo-e-bike

LVC on my two cheap controllers starts to limit power as voltage reaches the LVC. It's very nice, since it does a better job of not going below that voltage threshold than I could ever do manually. The result is, instead of having my BMS cut all power going up a hill when I need it, I can just keep ...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

What about 1000W hubmotor in 14 inch wheel? That engine is smaller and lighter. I tried to approximate the motor characteristics and fill them into simulator. It told me that that motor should climb 15% hill at speeds about 25km/h which is plenty for me. The Leaf 1000w is a little skinnier, little ...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I wouldn't try syncing power between left and right hub motors. This is a tadpole trike, not a delta trike, correct? Easy option would be a hub motor in the single rear wheel, or a BBS02 (or equilivent) between the pedals. Hub motors can be direct drive or geared. I use 1500w motors in 26" and 700c ...

Re: My econo-e-bike

Nice job! I had considered using Mr. Tuffys, but thankfully haven't had a flat since riding roadsides to work last year. Those two flats were with regular tubes and tires. Now I mostly use puncture/thorn resistant tubes and tires with some sort of flat protection (Schwalbe Plus), but I've mostly bee...

Re: 2019 16" moped/scooter tire pop-off: which is the most puncture proof?

I've had the Super Moto-X 20x2.40" tire on the front of my SWB recumbent for two years now, combined with a puncture/thorn resistant tube. It does get 180 lbs on it, and has had no flats, but only about 300 miles so far. The small crosshatching tread on the surface has worn off, but the grid of rain...

Re: StefEbike for my wonderful disabled wife

I had to rebuild the rear wheel of my Lynx, as my limited options for the original spokes turned out to be too long. Some of their threads were bottomed out, causing the whole wheel to not be as tight as I wanted. There were 6 broken spokes, all fractured at the threads! The new ones were 5mm shorte...

Re: Hire E-Bike build thread

Well for what it's worth, the controller on my wife's bike has been mounted between the seat tube and rear wheel for over a year now. Just opened it up to do a shunt mod and LVC mod, and it's clean as new in there. Granted this bike doesn't see rain, and only a few puddles. https://lh3.googleusercon...

Let us know how you like it. I have the same tire in 20" form, also with an alex DM24 on the front of my recumbent bike. It's nice on the pavement, but most of the trails around me are sandy gravel, and I'm about to try a Smart Sam as a second wheel to swap to. I also have a wider wheel to try, sinc...

I'd call it water resistant, with rubber on both sides. Holes for the wires through the rubber might be questionable.

Here's a 360 video clip of the Lynx and StefEbike. That's right, look at the bikes. Not me. :P It should load at 2880s if you have the hardware video acceleration for it. That's 5760x2880 distributed across the entire field of view, so it's kinda the same quality as watching a 1080p video. Yesterday...
