    Bionx 48V SL 350 XL battery charging issue

    And it was a standard laptop charger so since they make millions, it was CHEAP.

    Bionx 48V SL 350 XL battery charging issue

    46 volts and 1 bar -- that sounds about right. At that voltage it should charge happily if charger and battery are healthy. Getting in -- after you take out all the bolts (and unlock it and raise the locking handle IIRC) You need to pry all around VERY gently. If it is like the older ones I...

    Bionx 48V SL 350 XL battery charging issue

    Those voltages are pretty low and might suggest that you have one cell shorted (and it would have drained its little buddies wired in parallel). That would worry the BMS which might refuse to attempt to charge but still allow regen to feed the battery. Is there any change in current or wattage...

    Need Help Finding E-Bike With Features I want

    I had hoped that Trek still made their Bionx-based electrics. It appears that they have changed over to Bosch. This one is pretty expensive but has many of the features you wanted and is a "turn key" system...

    Would you put solar panel on your electric vehicle

    But they are NOT made to repeatedly bend ... I agree. I had two Renogy 100W "semiflexible" panels that I treated VERY roughly for a year before they failed, but one of them actually caught FIRE when it failed. They were wired in series to give a Vmp close to the battery voltage but that meant...

    Solar Cruzbike The Drunken Mosquito

    That looks like fun.

    The Ebiker Joke thread...

    A Cyclist - is a disaster for the economy: 1. He does not buy the car and does not take a car loan. 2. Does not buy vehicle insurance. 3. Does not buy fuel. 4. Does not use the services of repair shops and car washes. 5. Does not use paid parking. 6. Does not become obese. 7. Yes, and well...

    Recumbent trikes

    I have an older Terratrike Cruiser with a Bionx system that I found used for a good price. I have ridden it for ~2000 miles and simply LOVE it. It is a tadpole with two wheels up and one back. It is fast and stable and a joy to ride. I REALLY like the Bionx torque-sensitive assist and find...

    Using a torque sensor in an eccentric bottom bracket?

    The Bionx motor has a similar orientation requirement. That is because the Bionx torque-sensor strain gauge measures the BEND in the axle from the chain forces on the sprocket. The Bionx system is tolerant of some misalignment -- say plus or minus 30 degrees or so. It isn't unreasonable to...

    My Luxury e-Cruiser

    Ken, Thank you for a very informative and useful tour of the build process. Your results are simply stunning. Now all I have to do is come up with a REALLY simple project to try this on -- maybe a battery box -- thank you spinningmagnets for that link. Also a truly beautiful garage. I won't...

    My Luxury e-Cruiser

    What an exquisite one-off. Maybe everybody but me knows how this is done, but could you give us a couple of paragraphs about the design / fab processes? Are these processes accessible to us mortals, albeit for simpler items ?? Or do you own a composite fab house ???

    Day 6, a Bike for bad backs and my review

    That one is pretty cool looking. Although the fat tires are HEAVY, they are worth their weight in gold in deep sand. They float over the top of sand that would defeat pretty much any more traditional bike. I have fat tires on my ranch bike and can ride literally anywhere on the 20 acres...

    Came within inches of being killed on my eBike today

    Now that I live in rural Arizona, my choices of road near my house are limited to one or two roads, fortunately, none of them are heavily used just because there aren't all that many people out here. But, for example, the ONLY route to the nearest town is on I-10. Once in town, I have the...

    Came within inches of being killed on my eBike today

    In the early eighties, for three years I commuted 14 miles a day on city streets in Durham, NC which was, at the time, famous for killing bicyclists. After two days on the thoroughfares, I realized that I would not survive a month on those streets. I bought a city map and mapped out a route (a...

    Solar camping trailer to recharge ebike while overlanding

    With horizontal panels near the ground, wind is NOT a problem. The wind flow near the ground is parallel to the ground and the panels. I have ridden with 200W of flexible panels on my Terratrike Cruiser in 45mph winds without any problem at all. Gluing or otherwise mounting the "flexible"...

    Day 6, a Bike for bad backs and my review

    Sunseeker T3 CX looks fun. Nice and low slung. Low slung is really nice for slipping "under the wind" out here where the wind blows most of the time. I have had friends on "traditional" e-bikes complain about the "vicious headwind" when I had been riding happily alongside them and never even...

    Day 6, a Bike for bad backs and my review

    Have you tried a true recumbent tadpole with a mesh seat? My back isn't terrible (yet) but it tires easily and my absolute favorite bike is my Terratrike Cruiser. That mesh seat is quite literally the most comfortable chair I own. The headrest is absolutely necessary to keep tension in the...

    Bionx system

    I have done the same thing on a 37V LiMn Bionx battery -- added 5Ah of 10s1p RC LIPO in parallel with the Bionx a 41V LiMn Bionx battery -- added 5Ah of 11s1p RC LIPO in parallel with the Bionx The results are working fine for the past two years. But... neither of these batteries...

    The post above is well worth reading and leads to some other fascinating links. Nice rig.

    Anyone successfully spoke up a fatbike wheel?

    Is that simply because the motor is a larger radius than a hub and the choice of lacing pattern is more constrained ??

    Anyone successfully spoke up a fatbike wheel?

    I have no real experience in building wheels at all and the only wheel I have ever built was to put a Bionx PL350 motor into the front wheel of a Mongoose Dolomite with 4” tires. There was enough room for a 1-cross lacing but I didn’t have the right length spokes for that. I looked at radial...

    Recommended Trike for Ebike Conversion

    My Terratrike Cruiser with Bionx is a joy to ride and I now have about 3000 miles on it. The current equivalent model is the Tour II. The base model of the Tour II would be a fine choice. All of my e-bikes are Bionx powered so I don't have much basis for comparison, although I did put 600...

    Solar Trike build thread

    Looks like it is going to be a nice solar trike. Waiting with 'bated breath for more build photos.

    OK, who rides a recumbent???

    The two-panel tadpole design shown was essentially a prototype. The electrical system was well thought out but the mounting was just something I threw together over a long evening and then rode for several months. It was amazingly immune to wind simply because the panels were parallel to the...

    OK, who rides a recumbent???

    This was my solar PowerCruiser. The panels have migrated to a trailer so that I can use them with all my bikes. The Bionx system was upgraded to a 48V PL350 system and the old I2C system is now on the front wheel of my "Ranch" bike, a Mongoose Dolomite. Talk about a WASTE, a Bionx on the...
