    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...

    Methodology proposal to establish the assistance levels in an E Bike

    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...

    Methodology proposal to establish the assistance levels in an E Bike

    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...

    Methodology proposal to establish the assistance levels in an E Bike

    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...

    Methodology proposal to establish the assistance levels in an E Bike

    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...

    Methodology proposal to establish the assistance levels in an E Bike

    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...

    Methodology proposal to establish the assistance levels in an E Bike

    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...

    2023 Trek Domane+

    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...

    2023 Trek Domane+

    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...

    2023 Trek Domane+

    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 :) ]

    2023 Trek Domane+

    A quick heads up to Jlubeck (and others): The TQ system does include a null/off state with the display active but no motor assist. Whereas a simple press of the left handlebar button drops High to Medium and Medium to Eco, the deactivation of the motor from Eco requires that the button be held...

    Agree that sorting out good combinations of gear, assist, speed, and power input under various conditions takes some getting used to with the TQ HPR50 motor. What brand and model is the carrier in the photo? ~ Cost? Difficult to attach to the car?

    A Road-Cyclist Thoughts On E-Bikes

    It sounded like a simple question... I find Stefan Mikes' input most convincing, and put it in my own words in terms of power rather than percentages (percentages of what? ...too many combinations to toss around) or multipliers. My personal interest has always been in how much help the SL1.1 (or...

    A Road-Cyclist Thoughts On E-Bikes

    ... and it was my interpretation as well, based on the Specialized (poorly worded) text cited in my post #30. I was (supposedly) set straight by Specialized customer service, who specifically allowed that the motor could add up to 240W to my 125W for a theoretical 365W. Input from SL1.1 users...

    A Road-Cyclist Thoughts On E-Bikes

    I need to correct my characterization of the SL1.1 motor's power contribution. Communications with Specialized clarified that: The SL1.1 can boost my 125W with 240W at 100% peak power maximum assist (at >70 rpm) for a total nominal power or 365W. That goes a long way towards making the motor...

    The Fazua motor is great!

    Thanks DaveK92. I had posted a paper comparison among the lighter road oriented e-motors in another forum, looking for the kind of feedback you so generously provided. Your experience seems to confirm my general expectations. If interested, the comparison is post #30 here...

    Ebikemotion x35 speed limiter "fix"

    I neglected to thank Lucky22 for his generous input. Regards, much appreciated. Would like to dig just a bit deeper, if possible, such as the type of terrain you ride on. I'm drawn to the Fazua due to a perceived advantage on climbs, especially above 10%. I have read that the X35 provides...
