Thanks dadThanks Lumpy, I follow this thread to hear your view and updates about the LMT. Anything not about the LMT should be started on another thread. That's how forums work.
Thanks dad
...I was thinking about the LMT'D and the amount of assist provided in low PAS (1/9) on level ground in regards to getting a good workout and your heart rate elevated significantly without having to pedal 20 miles per hour to get to that point, but maybe 12 to 15 mph and get a good workout for the average person. What do you think based on your experience? Of course, I realize you could turn off the assist entirely, but that's 20 pounds heavier and much wider tires than my current hybrid, so that would be too slow, especially the inclines.
Also, what is the maximum speed you have been able to ride on level ground?
The new LCD appears to allow you to adjust individual power assist levels individually, such as changing 1/9 from 25% down to 20% or such type of change, but I haven't heard definitively whether those options work with the new LMT'D controller and software, which could affect the answer to the first question. I realize you do not have that LCD, though, to give any feedback on that.
With the new controller - the PAS levels make a difference in how much you work. With 9 levels, you can find one that gives you the right amount of workout... or just push it to level 9 and fly.
I think that setting is really for cadence sensor bikes as the Torque sensor feels your input and should decide the level of assist (within the selected PAS range) for you... I've found on the LMT'D, that the 500C display‘s 1-9 setting is really more about the speed ceiling for the assist. Basically setting the max speed your pedal input will go up to with motor assist before you are on your own - or at least doing most of the work.
No prob, I meant the response in a joking way. I agree the thread was hijackedDon't take it personally. I'm not bashing any individual.
LMT'D, and definitely Lumpy's, as he is the only one on the forum confirmed to have the new controller at this point, which affects the torque sensor based PAS response significantly compared to his earlier testing.There is very limited customer experience with the LMT so far so every owners comments are appreciated especially Lumpy's.
OK. Thanks for that update. I'm not sure how I feel about that. I was hoping you could limit the maximum output of the torque sensor based PAS to a percentage of maximum power regardless of speed when under 28 mph rather than a full cutoff at a given speed. So, if you're in a low assist level setting that cuts off assist at 12 mph (just as a theoretical cutoff speed), and you're pedaling to go about the same speed over a mile stretch, can you feel the motor cutting off and on as you straddle this threshold in the 11 to 13 mph range? I'm trying to envision how distracting this would be cruising down miles of country roads trying to limit the assistance if I feel/hear the power assistance kicking on and off, not to be confused with the unrelated cutting out issue with the old controller that you experienced.
Any idea what the speed cutoff is for PAS 1 to 3 ?
There is no cutoff per se - the motor continues to assist - at all PAS settings. I'd more characterise it as - the motor will take you up to a certain speed - and then you will have to take it from there.
Thanks Lumpydog. Ride1Up should give you a consultant job, with pay!
This is good news to know it's not cutting off assist based on speed and will continue to assist with some percentage of power with correlation to pedal power as well. So, it's operating as I would have expected, applying less power at lower assist levels while still correlating the power to pedaling force. While you are able to reach certain speeds on the flats with those assist levels while pedaling at different intensities, I'm not convinced the system is actually using speed as an input factor into calculating the power to deliver. I think you would need to repeat the test going uphill or downhill to see if those speed results per assist level change to confirm that. If it's just a pedaling and power algorithm for a given assist level that doesn't factor in speed, then you should see slower results uphill and faster results downhill when using the same pedaling effort on a given assist level as your earlier test. If speed is being used as an input factor, then the bike should compensate for inclines/declines in order to get the same speed results as earlier testing.
The 10 mph speed on flats with light/medium pedaling seems a little high (fast) to me for the lowest assist level, which is even faster with more pedaling effort, and faster yet (I assume) with strong tailwinds and on declines/downhill. That's where tweaking the assist level to a lower maximum power level would be useful, even with the torque sensor based PAS. Hopefully those config settings will be available with the LMT'D when using the new LCD KD218.
Thank you for taking the time to test this out and provide your feedback to those of us on the forum who are interested in the LMD'T.
Ride1Up should at least reimburse you for the additional money you sent them due to the original issue when you were attempting to purchase the new LCD.
You may be right about the KD218 providing more refinement on PAS levels. That would be a nice addition.
I might be down to 183 by the time I get an e-bike at this rate! lol Seriously! I can't even compare my own medium pedal power to myself from one ride to the next. I'm able to generate more power some days than other days with no explanation (no difference in caffeine, eating, soreness, temp, etc. that I can put my finger on). I might take one ride where my heart rate is 150+ for a sustained amount of time, then take a ride a day or two later, and have trouble keeping my heart rate above 130, which correlates with lower speeds. Just yesterday was a weak ride for me, after taking a full day off Sunday from riding to recover from my 66 mile ride Saturday night, I took a 12 mile ride yesterday, and my heart rate was averaging about 130, and fell to 120 on a flats late in the ride (still pedaling), and I could not overcome it, and I ended up with a lower average speed on a typical route that I take. Before getting on the bike, I don't know whether it's going to be a strong ride or weak ride. Of course, on the really long rides, I prefer the lower heart rate so that my body can efficiently burn fat to sustain my energy, and I'll even let up intentionally so my heart rate isn't too high for too long on those long rides, but I like to produce more power at a higher heart rate when taking rides under 20 miles.I should also add - that your riding experience may be different than mine. I weigh 183 lbs - weight will effect performance. Also what I call light/medium pedaling may be different for others!
I like your new video. It definitely sounds much more consistent in the power delivery now. The speedometer is working as well. I wonder how I'm going to like the sound of an e-bike motor at low assist when cruising along at 15 mph through the countryside. I'm used to it being pretty quiet on my standard hybrid, until I get on those roads that have been resurfaced with a thin layer of gravel, or worse, a thick layer of gravel just dropped on top! Those suckers are noisy, less smooth, and slow me down.
