  3. Thanks for your excellent reply, Reddy. Indeed, this is all much as I expected from background reading. Unfortunately, I don't have the time or the money to go higher or more involved than the current price point on a sondors x. I'm a poor aging conservationist... and really this island ain't that good a place to ride if you don't like getting killed by cars. Ideally I'd probably like a narrower-tire bike with a solid powerful battery and some gearing for under a grand. At my age, that simply may not happen affordably while I'm still around. I guess I could always get a small motorcycle and ride it slow... I'd prefer electric, but I'm already giving away many megawatt-hours free each year to the utility from the overage of my solar panels. Of course shipping adds $200 to an ebike shipped to my state too. best
  4. Kealolo, Your preamble included muscular difficulties with your thighs, which contain the largest muscle groups in our bodies, that produce the most power. The other caveat is that hills is just a general term and there are hills, then there are "HILLS” and Hawaii is a mountainous island group. I’d suggest that most of our 40,000 owners do ride on mostly flat routes judged by posts on this Forum since Sondors were introduced in 2015. BUT, Colorado owner Houshmand Moarefi, rode his 1st generation Sondors 36V - 350Watt, up the highest pass in Colorado but that fried the motor.... On the upside, that led to his 750watt motor upgraded that is posted here on the Forum. Member Matt Robertson, in California, has a home in a particular hilly area and led him to upgrade his Sondors Original, to the 750Watt motor, upgrading that Sondors, once again, to AWD, with front and rear 750watt motors .... then building a 750Watt Bafang BBSHD mid drive with that motor that cost more than our Original 1st generation Sondors, to contend with hills. Finally, he has purchased a Sur Ron mid drive eBike. https://lunacycle.com/sur-ron-x-bike-black-edition/ There are a lot of misconceptions about eBikes, their components and motor watt ratings. Unlike Lightbulbs, that are our most familiar wattage rated devices, which actually utilize the actual watts they're rated at, eBike motor manufactures can rate their motors as they wish. Even one of the Sondors X most common comparison, the Rad Rover eBike, that use the same 500watt motors that are rated differently. https://youtu.be/7K87AIiXFpY My 750watt labeled motored Sondors Original uses 1,400 watts under full power and my 350Watt labeled motored Sondors 2nd Gen Custom Narrow (probably the best Sondors ever available but no longer offered) will use 1,100 watts under full power. Likewise, riding up the steepest hill near were I live, on my Litespeed Vortex in the DFW MetroStool, for decades, before I bought eBikes and retired from emulating Lance Legstrong, I could generate over 1,000 watts as registered on my Power Tap power meter. All human power. https://youtu.be/gfcJuFtEcW Fortunately that hill was less than a eighth of a mile long before the grade lessened but it was the most popular route with various cycling groups in the region to challenge that hill. North Central Texicans are considered “Flatlanders" but that label seems quite disingenuous while riding the most popular yearly event in the state, the Hotter N Hell in Wichita Falls. https://www.hh100.org You might be able to ride a SondorsX in your environ but that’s a maybe you might regret and not be satisfied with its performance. The choice that is likely to meet your needs is the most hill capable Sondors to date. The Sondors MXS. It would be my next purchase and I’ve spent more than that on upgrading my Sondors. I've thought of a good comparison to equate to your last question in the last line of your post. Yes, quite a few of us do. In the general aviation society of privately owned aircraft its not unusual for owners up spend a thousand dollars a Knot on upgrades chasing maximum performance. REDDY
  5. alas, that's kinda what I figured. Ironic a bit since it isn't hard to pedal a regular bike without hills. And they're lighter. My 24v old project bike has sort of a geared motor and would help me climb hills pretty well, but it had its limitations too, mostly just being a lead-acid 24v system. So it seems like most of the purported 500w of the sondors x hub motor wouldn't be used, because 500w would be the power of several cyclists pedaling at once, seems like. So why get a sondors bike? just to go faster on the flat? many thanks for your reply...
  6. Last week
  7. Yeah Bruce, at least you’ve got a mid drive and able to carry Denture Cream and Viagria in your cute lil basket. Only Real Men and Exceptional Women ride Sondors....... EBike with a Vengeance! Oh wait ... and those gay guys are just FABULOUS! https://www.thesun.co.uk/tvandshowbiz/10735346/bruce-willis-sheds-hardman-image-as-he-wears-bicycle-helmet-while-zooming-on-his-electric-bike/ Yippie Tye
  8. Hello Friends, I am looking for a used Sondos X Fat Bike . I will upgrade it. 48 V 750 Watt Motor, new 35amp 60-80v KT Controller and 48 V 17,5 AH Triangel Battery. So it needs to to run. Thanks and all the best Björn
  9. Hi Bjoern. The graphic display of battery capacity is never very accurate and setting the value is trial & error.... a guessing game at best. My own battery graphical displays just acts as a reminder to check the actual voltage numbers displayed on a different screen than current speed and wattage. If the bars on the display are less than half total, it’s a reminder to check the voltage and that the voltage starts dropping more rapidly as it nears the battery’s BMS low voltage cutoff. It’s also the point where I switch to PAS 0 during downhills just to maximize reserve. Unused battery capacity, is capacity you don’t have to replace, an important tenet of overall battery longevity. The concept I equate, to how I pilot my aircraft. "The three most useless things in aviation are runway behind you, altitude above you, and fuel not in your tanks". Only once did I ever have to peddle my 1st Gen Indiegogo 36V, 8.8Ah, 15amp, 350Watt, Sondors Fat, the last couple of miles home after the battery low voltage cutoff. REDDY
  10. Hi Reddy, ok finally I got it.😀 Speed is shown correctly now. Needed to configure the Magnets (P1 and P2). Thanks fort he video: https://www.youtube.com/watch?v=B0F6x8V0NZQ The only thing what does not work is the battery staus. It shows always a full battery. I think it is P5 and I have set it to 15, like explaned in the video Any idea? Attached is a screenshot from my display settings. Thanks in advance abd all the best Bjoern

  12. Sorry to have to tell you but even the geared hub motored Sondors (more torque than direct drive hub motored bikes) are not good hill climbers without significant human power pedal assistance. That’s the prominence of mid drive eBikes and so far, Sondors has not entered that market. Although you might be able to struggle up a few hills with mostly throttle on the 48V /500watt Sondors X, the use of max power results in a lot of heat being generated inside the motor and excessive heat destroys components, especially in a particularly hilly environment. See ;https://boltonebikes.com/blogs/news/which-motor-should-i-choose-for-my-electric-bike?_pos=3&_sid=a80389be4&_ss=r The stark reality is that hill climbing ability costs more because all the components that produce more power are more expensive. REDDY
  13. Hi guys, I hope I'm not posting to the wrong area. I've been tempted to get an ebike for some time... well actually I bought a broken old 24v lead-acid bike and rewired it with new guts off ebay and it "sort of" worked but isn't working now, and I can't do hills with it. Here's the thing; my thighs have some degree of muscular impairment from some muscle problem with no medical name, but the upshot is that I can't peddle up much of a hill at all AND I live in a hilly neighborhood. In Hawaii. I'm wondering if the purported 500w bafang hub motor in the sondors x would allow a 200lb guy to go up hills without pedaling, or whether hub motors just won't do that very well. What has been the experience of people here? Thanks in advance.
  14. Grant with SONDORS TECH Support rectified the situation. SONDORS is sending me a new Bottom Bracket for my MXS and will reimburse the charges for a professional bike mechanic for the installation. Outstanding service, thank you SONDORS! Ordering a new SONDORS X today, for delivery to Anchorage, AK
  15. I contacted SONDORS TECH Support this morning, let’s see how they respond with a Bottom Bracket parts request for the MXS.
  16. Hi Bjorne, you’ll need to review the LCD Setup Video provided by Kyle of Bolton Bikes. You’ll need to change wheel size settings to 29’’ inches. That Should Do It. https://sondorsforum.com/topic/241-kt-lcd3-user-manual-and-setup-lcd8h-everything-you-need-to-know-sondors-ebike/ REDDY
  17. Hello Reddy, First a happy and healthy new year ;-)) I got now my parts and installed them on the bike. KT-LCD8H - New Color Display! https://boltonebikes.com/products/kt-lcd8h-new-color-display 36V/48V 25A Sondors Motor Controller for Triangle Batteries https://boltonebikes.com/products/36v-48v-25a-sondors-motor-controller-free-shipping Thumb Throttle https://boltonebikes.com/products/thumb-throttle The bike runs but the display shows double speed. That means when I ride 20 KMH the display shows 40 KMH. So everything has been changed but not the motor. Do you have an idea? Thanks and all the best Bjoern
  18. Good morning HalK, Yes, that’s the first thing I checked, followed by removing the Cranks, then checked the Bottom Bracket, every things was tight. thanks, Al
  19. The other thing I would check are the crank arm bolts. I had a similar crank noise on the power stroke from the right side. When tightenIng the bolts I heard a click on the right side, and after that, no more noise. Good luck
  20. MXS Started Making noise during today’s Ride. Post 300 Miles my MXS Bottom Bracket started making a Creaking and Snapping Noise on the Power Stroke. Noise from right side started first, then a few minutes later the Left side became equally as loud. The noise does not occur when Spinning, but only under load, regardless of 1-5 Assist or Zero Assistant settings. Any ideas?
  21. This Forum is VAST with thousands of entries and it’s not always easy to find the info that members or visiting non-members are looking for. yippie ki yay REDDY
  22. I did and looking at the pdf,l. I see on page 8 where there is speed limit settings. Oh well, cest la vie. Safe riding everyone
  23. Hello Swamp616, No not possible. Have you checked and read the thread on your Thin’s LCD in Instructions, here on the Forum? REDDY
  24. Just got my thin for Christmas. I am baffled on how to change the top speed. Could Sondors have removed that setting?
  25. After 311 mi/500 km of Workouts on my MXS, still a great ride! The SONDORS MXS is more agile than my SONDORS X, but the SONDORS X, with it's larger tires acting like huge flywheels and 14 additional pounds, is much easer to keep at speeds above 19 mph at zero assist. Of course it's Flat SW Florida. I moved the KINEKT seat suspension, Ritchey adjustable bike Stem, added the Selle SMP TRK saddle, and added the FOOKER MTB pedals etc. I use the wahoo ELEMNT and related monitors to track Cadence and Heart Rate in real time. The 750 watt motor has become a little less quiet, but still super smooth. The MXS color monitor provides all the power I need to run my iPhone 11 Pro Max, ELEMENT, etc. The ROCKBROS case is a must have. I call my ride the "NOSE", I ride this rout three times per week and take the weekends off to recover. I typically ride in assist # 1, until I reach 20 mph, then I move to assist # 0, until I have to down shift to hold my speed and cadence, usually about 18 mph. This helps keep me in Cardio after the first couple of miles warming up. As you can see there are several turns, turnarounds, and stops on this rout. I downshift at these points and then upshift to get back into the ride. The area of max seed is a sprint past the TSA building, you can see the small percentage of Peak in the Heart Rate. FYI, after a bone-on-bone diagnosis in 2017, my right knee has totally rebuilt all cartilage, using PEMF, Prolotherapy, and SONDORS eBikes, what a winning combination.
  26. I can’t speak to the reliability or anomalies that might be reported by the newer color LCD display. I don’t use that display but rely on the KT-LCD 3, but hall sensor failures are, Almost Always, due to the Lg Higo motor connector, under the right chainstay not fully connected. The exceptions could be to moisture/water incursion into the motor or connector or below⬇️. The Hall Sensor system is not a replaceable part but integral within the motor and its windings. But since that error and the throttle error both disappeared, I’ll assume that with powering off then powering back on of your bike, that the controller (or maybe even the display) rebooted and corrected theses displayed errors. The electrical cut out is due, most likely, to either the battery’s low voltage BMS (battery management system) cut off function, set to stop the battery’s voltage from going so low that it can’t be charged or recovered, or the same setting in the controllers design to do the same, due to low battery voltage. Although the voltage dropped so low to cut off the current, the battery, recovered its voltage somewhat (due to individual cell balancing) after a time and you were able to restore power. See: https://www.electricbike.com/introduction-lithium-18650-batteries/ https://www.electricbike.com/motor-tech-learn-the-terms-part-1/i There is a lot of useful info @ electricbike.com and you should review the ones you’ll find informative under the technology header. Sondors eBikes are not good hill climbers, that is the prominence of mid drive motor eBikes. Nor are Sondors eMotorcycles as designate as eBikes with PAS . They perform best when peddled, as a major part of the motive force. The better more powerful class of eBikes designed for Hills that are Higher Powered Bikes, that also serve as eMotorcycles look here. https://lunacycle.com/sur-ron-x-bike-black-edition/ REDDY
  27. Hi REDDY, Thanks for the tips and the Battery Voltage table. FYI, my Sondors X has an upgraded 25 Amp controller, so the two are fairly similar. I fully charged both batteries, X battery read 53.6V and XS battery read 53.2V, so seems that test is good. I swapped the two batteries and rode both bikes with my wife. We did 14 miles with no problems. The XS battery was down one to 50.1V, so again seems about right. X battery was a little better, but my extra 50 lb body weight probably accounted for that. The next day I put the XS battery back in the XS bike and rode it hard (lots of hills with little pedal assistance). When I got to 20.4 miles total it cut out and I got the following error: Error Code 24, Fault with motor hall sensor inside. After a while with starting throwing Error Code 22, Fault with throttle. A while later it came back OK and I was able to ride home. This failure is not exactly the same as the previous failure in that everything seems to go dead (no error codes, no power to display. Regardless, I have a problem to fix. To me it seems that the battery is OK (good since I am not excited about spending $400 on a new battery) but I have an intermittent fault. Is the main problem the motor hall sensor? Is the fault with throttle (Error code 22) just a resultant fault? How do I fix the hall sensor? Where do I but the parts? I recall posts from some time back talking about this but cannot find them. Any help you can provide is much appreciated. Thanks, SamCR
