    Looking for Bafang Ultra tuning software

    I had a dead Biktrix headlight after replacing the wiring harness. Problem was that the headlight has a required polarity since its lamp is an LED. The "+" and "-" for the prongs are nearly invisible, and the leads are only sort of color coded (black and a vague rust colored smear). Reversing...

    Looking for Bafang Ultra tuning software

    Got enough info from the EggRider facebook group to keep trying, and I eventually succeeded in getting everything to work a couple of weeks ago. The EggRider display and app are way better than the Bafang display. I could suggest (and did) minor improvements. Anyway, no functionality or...

    I have gone to eggrider's facebook page. I hope I passed the entrance exam.

    Looking for Bafang Ultra tuning software

    I just got an Eggrider v2 and cannot update its firmware. The instructions fail at step 12. I have the current version of the Eggrider app and nRF Connect, but nRF does not do what the update instructions claim. Without updated firmware, I cannot activate my Eggrider and therefore cannot use...

    First Solar Powered eBike on the Block!

    In addition to all the felicities you list, Indiana, you have oxygen! Most of today's ride was above 10000'. If you ride (or walk or ski) the nearby Continental Divide Trail (off limits to motorized anything) it is mostly above 11000', and some stretches are much higher.

    First Solar Powered eBike on the Block!

    I rode up Falls Creek Rd, FS Road 39, on the west side of Wolf Creek Pass, famed in song and story. The road is at the northernmost end of the South San Juan Mountains. The mountains seen in this photo are "across the street" in the San Juan Mountains (another range). Eleven point four miles of...

    Biktrix Juggernaut Ultra 1000 Review

    Yes, that's what Biktrix folks say too. The rim geometry is wrong for holding tubeless tires. I've been thinking of getting a set of 29" wheels for 2" tubeless tires suited for pavement. For rough roads and trails I'll stick with the 27.5"x3.0" which came with the Jugger.

    Juggernaut Ultra FS

    Just got the FS Ultra today and have made a few short test rides to get everything in order. Yes, it's heavy. I'll be seeing soon whether the rear suspension is worth the weight. I got the 27.5x3.0 wheels and standard shocks. I'm considering using it to commute to the top of Wolf Creek Pass...

    Everything you say, Indiana, is no doubt true, but you neglected to mention the downside: Indiana. The Rocky Mountains are pretty great all year 'round, and the SW desert is just a short ride away. We suffer our inconveniences gladly . . . if not silently.

    First Solar Powered eBike on the Block!

    SURPRISE! Not expecting anything today, I went to town for an hour. On return, a box full of undamaged Juggernaut FS awaited me at the door. Assembly was quick and easy. This bike is heavy! Good thing it's got a motor. Aware that some people find loose mechanical connections on delivery, I...

    First Solar Powered eBike on the Block!

    My new bike is stuck in Denver for the last three days. I called DHL Express (!) to ask when it will be here. Just three more days, they said. Let's see, three plus three equals six. Six days to go three hundred miles. That's fifty miles/day. DHL could easily pedal it here in the same time. The...

    First Solar Powered eBike on the Block!

    However, now that I think about it, passive solar space heating fully qualifies as directly solar powered. I designed and built a house near here in the San Juan Mountains of southern Colorado which was 100% passive solar and lived in it for fourteen years. No heating or cooling bills at all...

    It's really hard to use the juice from a solar panel directly for anything without involving a battery to even out and/or store the power. Therefore, by your strict standard scarcely anything (except the planet!) is solar powered.

    Oh, come on! This is a point too fussy for me, and I'm really fussy.

    First Solar Powered eBike on the Block!

    Solar-powered, Mtl, as you know, does not necessarily mean running directly off PV panels. My house is off-grid and solar-powered via storage batteries. Innumerable electrons from the sky go begging when the batteries are fully charged, and they often are. Why buy gas for the car to go to town...

    Update: Only three hundred miles to go but mostly mountains. Terrible things can happen in the mountains!

    First Solar Powered eBike on the Block!

    Rolling slowly toward SW Colorado is a truck bearing my ebike, a Biktrix Juggernaut FS. It started out 1200 miles due north of here in Saskatoon, then it veered puzzlingly to the southeast until it got to Cincinnati OH, which is 1500 miles east of here. There the truck rested for a while...
