    What does Nm really measure and is it applied the same by ebike manufacturers.

    They should not be used interchangeably they mean different things, they are related but very different. Laymans using torque for power is the source of much confusion and wasted time. Do you use distance (miles) interchangeably with speed (miles per hour)? One is a component of the other they...

    What does Nm really measure and is it applied the same by ebike manufacturers.

    Personally not one for imprecise artful language, I agree there are many subjective things about a bike that can make it feel better to one person vs another, however there is no alchemy involved there is applied science (geometry, physics, chemistry) to make this happen. The color, the shape...

    What does Nm really measure and is it applied the same by ebike manufacturers.

    Be careful again torque is not power, gearing the drill down does not increase its power it increases its torque. 7 amp x 120v = 840w of power, the motor turns that power into torque and rpm along with gears. The speed control of the motor(variable speed trigger) adjust its power while a 2 speed...

    What does Nm really measure and is it applied the same by ebike manufacturers.

    Simply put torque isn't power, and focusing on torque is the wrong thing to do. Power (kW) = Torque (Nm) x Speed (RPM) / 9.5488 Torque is one component of power, the other is rpm, one without the other is not very useful. Torque can be multiplied by gears and wheels, power cannot. Gears trade...

    Motor efficiency Standard Bafang G510 Benchmark Bosch CX + 15% Bafang Archon X1 + 30%

    Watt hours per mile (Wh/mi) is probably the best unit to use to compare efficiency assuming all else equal (speed, wind, terrain, etc.): Stock Bafang G510: 714 Wh / 15 mi = 47.6 Wh/mi Bosch CX: 600 Wh / 15 mi = 40 Wh/mi As a comparison on my Juiced RCS with Bafang 750w hub motor on flat paved...

    As I feared, again why I would like simple dedicated display for critical info to focus on non fancy but sunlight readability and everything else in smartphone app.

    I agree I made the this point in the other thread for new display feedback. I prefer a small display integrated with buttons off to one side and smartphone mount in center, even better if bike has app to display more details and get updates on large smartphone display, while common stuff like...

    Watt Wagon direct competitors?

    My Juiced RCS weighs 85lbs, made in China, free shipping from their California warehouse, They also have 100lbs bikes with free shipping. 7lbs more battery will make almost no difference in shipping. Cost may be a different issue, the battery will be very expensive and if they have limited...

    Watt Wagon direct competitors?

    The battery is prob 7lbs more than the Hydras, so maybe 65lbs if WW did this, how many of you weigh 325lbs that the Hydra can take and is 7lbs gonna make a diff? Way more weight issue from rider than bike battery assuming they know how to make the frame.

    Watt Wagon direct competitors?

    Doesn't have to be 85lbs, probably a 15lbs battery. I just got back from a 30 mile ride and used 25 wh/mi because I didn't care and it was great. Never regretted more battery, my goal is no range anxiety and longer overall battery life due less deep cycling. Based on my current 1kwh battery on...

    Watt Wagons new display - colors and UI layout feedback

    I will say my monochrome Juiced LCD has no problem in the sun, and a nice subtle blue backlight for night: Eggrider has nice high contrast monochrome OLED display: Common theme here is small bike display with controls, large smartphone in the center.

    Watt Wagons new display - colors and UI layout feedback

    Can be small and color too like the 500c, and damaging in a crash not really playing into my preference for smaller screen with integrated buttons. My small Juiced display will get trashed just as easily if not more so since its hanging out more to the edge of the bar. For me its about less...

    Watt Wagons new display - colors and UI layout feedback

    My opinion having a Juiced bike currently and looking at various others, I prefer the smaller displays integrated with buttons then say have a app that displays more details if wanted since I like to have my phone mounted center on the handle bar. The extreme of this is Super73's minimal display...

    Used to be a PC guy, still have one in the garage, but Parallels is a wonderful thing on the Mac, just 3 finger swipe between Window and Mac as needed. Hope they get it working on the new M1 macs. You're programmer looks to be Winforms based, is the SDK .Net based for the Archon?

    Me on the other hand do programming for a living, using a Mac (with a parallels Windows VM), So am happy to learn I can program it myself to my liking :). I see it has Eco and Sport which is exactly what I wanted, perfect.

    So this seems to be the core issue, again it sounds like simply how the assist levels are programmed and not a hardware limitation. Honestly not the way I would do it, I would have at least some of the lower assist levels ramp down to the 750w version, sometimes you want to get the exercise or...

    Thanks scrambler, this is exactly what I am asking. If I where to program the PAS level for the 2300 archon I would probably do something like 2300w Level 1 = 750w Level 1 2300w Level 2 = 750w Level 3 2300w Level 3 = 750w Level 5 2300w Level 4 = 1000w Level 5 2300w Level 5 = Full power...
