Looking for a Torque Arm for my pull-off KHS fat tire fork. https://lunacycle.com/fat-tire-rigid...6-non-tapered/ My nifty drawing below of how the torque arm could look. . It would attach to the fork with a top bolt( in red) and a bottom bolt (in blue). I'm attaching a 500W Bafang front hub...

I'm transitioning from a sticks & bricks house to a Tiffin Allego Bus (RV). I plan to travel the country off the grid with 1000W of solar and a massive bank of lithium ion batteries. The first generation of programmable solar controllers built for lithium ion batteries are just coming out to...

Can I use Two 24V Lithium Batteries in place of a single 48V battery? College taught my I can wire them in series and it will work, however real life is rarely as simple as exams questions. I currently use the http://lunacycle.com/batteries/packs/48v/48v-panasonic-11-5ah-or-13-5ah-dolphin/ 48V...

Any update on this? I plan on buying the same kit to power an old (but working excellently) 48V 1000W Direct Drive front wheel drive motor that lacks an internal speed sensor. BMS Battery indicates that an internal speed sensor is required, but I think an external sensor & some soldering can...

Dual Drive HIgh-Torque & High-Speed: Why haven't I seen this? My initial thoughts for building an electric bicycle was to build a dual drive system. The front wheel would be high torque but with a low speed, activated by a PAS only and it would max out at about 15MPH. The rear wheel would be...

Thank you all for the great information! :D I'm impressed with the different eBikes several people have built and shared with on the forum. It appears that almost all of the bikes that meet my performance guidelines required serious modification as a matter of necessity not desire. Does...

Did you post a link to your build? What frame did you select?

What I'm looking to build is very similar to the photo you posted, but I intend to make my bike look as much like a regular bike as possible, using a kit similar to this https://bmsbattery.com/ebike-battery/701-48v116ah-bottle-09-panasonic-battery-torque-sensor-battery.html. Do did you write a...

The task of fitting motorcycle rims to a Fat Tire bike frame and lacing in a hub motor seems like a considerably amount of custom work with special tools, or is the process less complicated than I'm anticipating?

My SandViper is a hardtail 18in fatbike with 4x26 wheels and I've gotten it to 43kmh and felt very safe with the major limitation being gearing and the fact that i'm 6'1 @ 226lbs. My thoughts were that front suspension would absorb the impact of hitting a pothole at 35MPH, as I don't believe...

My post made it very clear that I was aware that dual suspension fat tire bike frames existed. My question pertained to the frames ability to handle standard road conditions at 35MPH, a speed that a only racing bikes are built to handle. My initial reaction was that you were trolling, but...

(Reserved for the component research) Frame: I am looking for a dual suspension frame that can withstand the impact of hitting a standard pothole or road elevation change while traveling at 35MPH. I’m not looking for anything extreme, essentially I would just want to be able to follow a scooter...

I currently have a the SSR Sandviper, a 350W fixed frame 26x4 Fat Tire bike and I love using it to ride to work at 18MPH. I love it so much that I want to build a faster and safer Fat Bike. I’m looking for anyone who has experience building electric bicycles that go over 25MPH, in fact going...

The motor I intend to connect to this kit is similar to this, https://bmsbattery.com/ebike-kit/469-q11-48v1kw-front-driving-disc-brake-hub-motor-ebike-kit.html.html. [/url] This uses 8 wires, 3 phase wires power the motor, 3 hall sensor wires control the speed, and a +5v & ground for powering...

I was going to order the same controller with the 48V bottle battery. https://bmsbattery.com/ebike-battery/681-48v10ah-bottle-09-e-bike-battery-pack-battery.html Have you made any progress? BMSBattery.com states "It only fits the motor with inner speed sensor. Please make sure your motor has...
