Re: bluetooth BMS?

The balance wire between 10 and 11 has a problem?

Re: My econo-e-bike

Ah, got it. Forgot to say I had the same problem with the paper thin sidewalls on my 20" Smart Sam requiring more pressure than I thought to corner on pavement.

Re: My econo-e-bike

Took me a while to choose the Crazy Bobs, but after riding them for a while, I'm definitely going with something else next. I've thought about the Marathon, but I'm leaning toward better offroad traction now. I replaced my rear tire with the old Forte knobby I was using before so I could get my bik...

Re: My econo-e-bike

Oh good, I'm glad the battery turned out as requested! Man, those are some nice views, and the power available sounds great! I do use the Marathon MTB tire on my wife's bike (with puncture resistant tubes on all bikes), and not only did it give me the impression of being quite puncture resistant, bu...

Re: My econo-e-bike

Good luck! I'm guessing it didn't arrive yet? Personally, if I had to work with a pre-built battery, I'd swap out the BMS for a smart bluetooth one anyway, so I can monitor cell group voltages.

Just to ease your worries, :lol:

Re: Around the world on a solar ebike

Great work! Did you encounter any unexpected difficulties, such as flat tires? What parts of the trip did you like best? Would you rather be on a road that's straight or curvy? Also in the video I sometimes saw you cranking pretty fast in low gear going uphill, when I would have expected more motor ...

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: 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.

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 ...

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...

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...
