Any progress/improvement? Your best bet is likely to be a good fitting as Calcoaster suggests. Not the bike shop variety, but from a professional fitter with bio-mechanical expertise, like the guy in the attached clip, if you can get a hold of one within your reach. It's an expense, but the...

Just thought, backed up by scant knowledge, but have you matched the saddle position (relative to cranks) of your painless bikes? Have you tried switching the saddle with one from your other bikes?

Thanks to Antonio and Will for adding to the dearth of information from TQ on the HPR50. It's a shame that we have to sort these parameters on our own. Because my maximum sustainable heart rate and power are lower than Antonio's minimums, I'm very interested in figuring out how to get the most...

Apparently 96% Off/Eco was too easy for Antonio, had to go to 100%, and came out thinking he may need to trim back the support! Then again, he did make pretty good use of the available 84W and acknowledged finding the help on the climbs. The support drops below ~40W is a meaningful insight...

Will look into your rides tomorrow. This is good information that others will appreciate in the larger forum. You should post both rides there.

Great information. Much appreciated. It's bringing peak and nominal power into real world focus. 300W peak power for 6+ minutes on a scorching day seems pretty good. I was thinking it might keep it up for about 10 minutes on a cooler day, and it seems to be be within striking range...

Agree with your example values, though both control - the 50% assist up to 200W of rider input, the 100W max boost at higher inputs. I'd be interested in knowing how long the nominal 250W TQ HPR50 motor can sustain the max 300W output, its power curves, and how it self protects against...

It doesn't work well for me as yet. While Rider Power and Motor Power are visible on the TQ display (as suspiciously variable as the latter is), the Karoo 2 only reports Rider Power, drawing a blank for its Combined Power metric. Hammerhead punted on it back in March (see attachment). I hope...

I was able to sideload the Ki2 workaround (highlighted by DC Rainmaker and Shane Miller) onto the Karoo 2. It shows the front and rear chain positioning very nicely. Not sure of the origin, but I also get a nice two beep alert when the next rear gear would trigger a concurrent Synchro 2 front...

As someone who started his career with analog computer (slide rule), I'll have to defer to Antonio, when he gets his +SLR 6, to dig a little deeper. Another handicap is that my Karoo 2 head unit only records my power input, credibly, but not the motor's contribution. I expect they'll...

Though we all have e-bikes in mind, we're coming at this from different perspectives that, not surprisingly, reflect our own current health, capabilities, priorities and goals. Due to cardio-vascular limitations, mine are to ride and climb without inducing debilitating chest pain. On the other...

Not sure how to go about the calculation, but happy to pass on my data. I don't have a proper FTP, but I'd say it's 100W by default, in that Angina doesn't let me sustain anything higher. At age 75, it's unlikely to get better. My combined rider and D+6 and accessories is 90 kg. I'm down to...

These maxima, whether 150/225/300W, or 154/249/300W paired to 98%, 137%, and 200% seems preferable to the draft's 74/102/142W. They would suit a 150W rider well, provide headroom for when the 104W rider is able to contribute some additional bursts of power.

I'm not too handy with posts, so answering to post 82 here, then switching to the other thread. Feel free to move this if you can. Your Assist levels of E 100%, M 137% (right?), H 200% are sensible. If understand correctly, however, when applied applied to 104W rider contribution, but rather...

Thanks for sharing your draft. Much appreciated. The Trek App allows you to fine tune the motor output through 9 settings: Max Power, % Assist, and Pedal Response, for Eco, Mid and High. I'd be interested to see what tuning values you start out with when you first hit the road on your e-bike...

Can you share your assist methodology in the meanwhile? My attempts are turning out to be a crapshoot, despite attempts at 'rational'. My main challenge is getting satisfactory support in both Eco and High, conditioned by my (cardio-vascularly limited) 100W power input (post #57). At 100W x...

Pardon, but your post sparked my curiosity. You use so little assistance that I wonder (coming from the other end of the assist spectrum) what led you to e-bikes in the first place. I also wonder where you get the projected range estimates from. Have you tested the Creo to the point of batter...

Here's my experience with the Domane+ SLR 6. I got the Domane+ because Angina limits my medicated heart rate to 100 bpm, which corresponds to a sustained output to ~100 Watts. I can push to ~150W for up to a minute but have to stop to recover beyond that. That colors my experience. Pedal...

Yes, the display reports the rider power input and the motor's, showing "0" when not assisting. They don't seem averaged and tend to vary quickly. I cannot vouch for their accuracy [other than at zero :) ]
