They put a watt hour and amp hour readout on the display. That's nice. JR seems to now use LG cells. I'm wondering if anyone feels confident in any performance cell? They seem to be using 3200 mah cells. They say 600 cycles to 60%, but what's the capacity at 200 cycles? And how useful is 60% of...

http://www.voltbike.ca/voltbike-yukon.html (Link Removed - No Longer Exists) Voltbikes have done well enough to open a US warehouse. Bafang is a solid motor. Both have interesting models. There are others in the price range. Something like this. For 5 miles with two short hills and a couple of...

The motor has a controller. A 48v battery goes from 54 volts to about 40 volts. As it gets to 40 volts, it cuts out to protect the battery. But the more power you try to get from the motor, the lower the voltage drops, but then the voltage recovers. The monitors are independent. The controller...

I recently bought a Chinese multimeter with a 100 amp shunt. Basically you hook up 3 or 4 wires (or a relay) and then you have a color display showing amp flow, voltage, watt hours, battery capacity in %, all that stuff. Oh, yeah, and the display is wireless, so you can put it anywhere within 20...

The pack is rated 6 AH and 50-52 volts new. I ran it for 15 miles on the bike, so up to 700 watts draw. Put it on my discharge system, just lights, so 70 watts. That's not an ebike draw. I got maybe another 40 watts, but the voltage was dropping like a rock. For me it is now a 210 wh pack, or...

Thanks. I have a 30q pack that is now one year old and has only been used steadily for a few months. I guess I will do a capacity test with a watt hour meter. I have a pack with Sanyo GA cells. It's kind of a favorite with performance riders. The data sheet shows a big loss of capacity quickly...

At 45 volts with a 13 series pack, the cells are at 3.46v. That's not empty. Generally 'empty' is when the LVC trips. A lot of these cells go to around 3v. A bad cell or two can bring down a parallel set and that set might drop a lot, and that might set off the LVC. I get this sense that maybe...

If the pack is at 45 volts, that doesn't sound right. There's a lack of troubleshooting advice for battery packs. The cells in a pack are supposed to be balanced and they are supposed to age evenly. If you took all the cells out and separated them, what would you find? The best you can do is...

This is pretty much the end of range anxiety. The battery would fit on the rear rack of a bike, but I’d go with a cargo bike or some kind of recumbent. Fifty pounds is fifty pounds, but the pack is not huge. And it is 2.6 kwh. That is roughly five times the standard packs they put on most...

Luna made a YT video showing the FLX on a hill and the FLX didn't do very well. It's a very small motor and I doubt it sheds heat very well. FLX promised a torque sensor. The video isn't there anymore and I heard something about FLX threatening to sue Luna. So maybe that is why the video isn't...

Scrounging like this can work out. Here are three suggestions: 1) This might be the wave of the future. It's the Vruzend system to build packs with a mechanical connection. Micah Toll has a decent video on how it works. Toll has an ebike book and an ebike battery book, both good. I have a kit...

You can buy 20 cells, wired up for 36v with an XT 60, for $35. The modules are 4.4 AH. You can buy 200 cells, in 10 modules, for $249 More info here. Do your own research. It's an interesting price.

Unfortunately, these forums can't answer questions like this anymore. People are going off in too many directions and it's too easy to mislead people. I recommend Micah Toll's book on batteries, a Kindle or softbound, to really try to understand. A forum like this exists to sell a certain kind...

California will require certification of the power. If the manufacturers game the little certificate, they will end up where Volkswagen ended up, with the diesel fiasco. It's really sad that the big companies seem to be gaming the power, right now. There's no way an ebike will ever have more...

Sure, if someone rides a 1500 watt electric bike on a bike path and plows into someone, the authorities could take the easy way out and say "We don't need electric bikes of any kind on the bike paths." I don't know if Karl has made the case that high power ebikes would be a big selling point...

People camp where they want, over a large area. Cost is $40 for two weeks, $180 for the winter. You can pretty much go anywhere you want on an ebike. This is my Trek 820, Golden Motor Magic Pie, and a Luna Mini Battery. Around $1000. Marathon MTB tires.

They cut the price on that motor by quite a bit. I think the rear option is new. I think for small adjustments people use washer/spacers. It's basically for steep hills. Luna has a video on YouTube. You could just buy a more appropriate fat hub for a lot less money if you don't have steep...

https://electricbikereview.com/forums/threads/are-electric-bikes-really-transportation.3/#post-7 My first post here. I have less faith now ebikes can be car substitutes. Trucks and SUVs are what sells. I'm in Quartzsite where the giant RV show is gearing up. I looked at 5th wheel double slide...

https://electricbike-blog.com Karl writes a lot about fats in the snow. Writes well and knows the motors. I'm sure he would say build.

http://www.motostrano.com/BOSCH-Electric-Bike-System-Parts-s/8181.htm So that would be a Lenny price? He doesn't advertise it. The Motosrano price is much higher. Can I really buy a bike today and count on your price? If they shift to 48v systems will they catalog older 36v? Should people be...
