Re: Lowrider eBike project

For sure. I use a 30 amp fuse on my wife's 1000w kit, and a 40 amp fuse on my 1500w kit.

Great pictures again man. These give me vibes of a few computer games, like Half Life 2.

Re: Around the world on a solar ebike

Too bad recumbent bikes are still a billion dollars. LOL Keep an eye on Craigslist, LetGo, ect. for used recumbents. Most don't have suspension, but I was able to get this Optima Lynx for $280. Swapped out the wheels and got a front suspension fork to work! https://lh3.googleusercontent.com/viVsAm-...

Re: StefEbike for my wonderful disabled wife

Yes, he had a telescoping pole it was mounted on. I'm not sure if mounting it on my helmet would block out a lot of the downward view. If I'm going to look dorky anyway, I could raise it up a bit on a pole.

Re: StefEbike for my wonderful disabled wife

This is a sample of 360 video footage from the beginning of the year. We should have used the camera more! I think the format does a better job of feeling like you were there, since you can look wherever you want.

Re: My econo-e-bike

That regen howl isn't so bad; wind on that mic is pretty bad though :) Those sure are some steep hills! I mounted the cam on my helmet to avoid the vibrations. Also found the sample of 360 video from the beginning of this year. We should have used it more! https://www.youtube.com/watch?v=XeLD6lq_2pY

That sounds like pretty good range! What speeds were you aiming for? There were a ton of bikes out, for what may be one of the last pleasant weekends of the year, and temps were around 65-70 degrees the whole way, with a little wind. You just need to lower your standards :P My last video was done wi...

Re: bluetooth BMS?

Basically the whole time, my meter showed that group 11's voltage was 4.165. I turned off the balancing right after that screenshot, since it was balancing 11 sometimes when it should have been balancing everything but 11, and the voltage reading went right back to 4.165.

Re: New 14s battery pack, US18650VTC6 vs NCR18650GA

Excellent. Let us know what your range turns out to be eventually :) I consider my 14s6p MJ1 packs to be 40 miles at 15-20mph, 20 miles at 30-35mph, and a bit more when used on the recumbent.

That's a nice giant pack! Are you relying on only two bus bars to handle all of the current for some of the serial connections?

Re: bluetooth BMS?

Nice mods. I've been chasing a similar problem, just with group 11 on my wife's BMS. During balancing I caught a screenshot of group 11 reading 17mV higher than it actually was, confirmed with my meter connected to group 11 at the same time. I don't think the problem ever happens when the BMS is not...

Re: Want help to review my ebike part choices

I'm sure you could do 0.15x8mm nickel strip, since that's what I used on my 18650's. Should be able to carry a little more current, if you have access to 8mm as easily as you would have gotten the 6mm.

Feel free to take a look at the parts list in my signature link if you'd like.

Re: Best rear tire for 26" DD hub motor

The best one I've found is the Schwalbe Marathon Plus HS 468 SmartGuard MTB Bicycle Tire. I put about 2200 miles on my last set on a DD running 3600W with ZERO flats. They're expensive ($45-$50 a tire), but worth it when you're not having to take off your rear wheel all the time. You can get it in ...

My motor did have some hall sensor/position glitches at the end of that ride, and it did have a small puddle underneath it on the car ride home.

So both fenders connect right to the axle, eh? I wonder if I can make my front fenders do that, since forks don't like to include eyelets for them anymore.

Hand holding indeed... The smart BMS has shunt resistors built in, and the software can display current flow both in and out of the battery.

Re: DIY battery BMS issues

Put the negative meter probe on the black balance wire instead of the negative main power connection. Then put the positive meter probe on the first white wire, and work your way up one at a time looking at the voltages. Do you have a bluetooth or PC interface for that smart BMS? The spacers and all...
