    After repair I lost overdrive with Enviolo manual

    The URL has changed: I'm still not clear why the interface might need to be reset to get the full range after changing frayed cables in the shifter ("controller" in Enviolo-speak). Could it be because users forced on the shifter at stand-still, and strongly enough to turn the interface on its...

    [confused] Torque sensor, gear ratio, pedal assist

    Out of curiosity, what's the brand? How does that torque sensor look like?

    [confused] Torque sensor, gear ratio, pedal assist

    So, unlike what I read, mid-motors with torque sensors do provide more power the faster you spin, so you really should downshift and spin like on a muscle bike so as to keep the motor in the zone it's most efficient?

    [confused] Torque sensor, gear ratio, pedal assist

    That's also what I thought (spinning at least 60-70 RPM to keep the motor in its sweet spot), but I read somewhere that some mid-drives with torque sensors at least provide less power the faster you spin because it figures you don't need much help if you can spin fast. Hence the confusion...

    [confused] Torque sensor, gear ratio, pedal assist

    Hello, I'm confused about how mid-drive motors with torque sensors work in conjuction with mechanical gear ratios. Am I correct in understanding that the stronger you push on the pedals, the stronger the assistance from the motor? And conversely, the faster you spin after selecting a...

    [Gates + Enviolo] Why too hard up hill? What is that part for?

    To check if the issue could be with the shifter, the cables, or even the fasteners wrongly set at the end of each cable… is it possible to manually dial the interface, eg. move it to full underdrive before riding up a hill?

    [Gates + Enviolo] Why too hard up hill? What is that part for?

    The issue with hills could just be a problem with the cables, preventing the rider from reaching the lowest "speeds": https://support.enviolo.com/hc/en-us/articles/11954289237522-How-to-fix-insufficient-ratio-range-or-speed-on-135mm-solid-axle-hubs#problem-diagnosis

    [Gates + Enviolo] Why too hard up hill? What is that part for?

    Thanks. Problem is, there's no reseller here, only a single LBS who's never seen an Enviolo. Upgrading the Brose software seems even more unlikely without being a Triobike/Brose retailer. The joys of buying a sophisticated bike with no local skills (not my choice). We'll give it a try anyway...

    [Gates + Enviolo] Why too hard up hill? What is that part for?

    Thanks. I assumed it was for a derailleur, to fit both transmissions (gear hub and derailleur). https://www.bike24.com/p2141597.html

    [Gates + Enviolo] Why too hard up hill? What is that part for?

    Hello, This used Triobike Boxter cargo trike sports a Brose mid-drive motor, 50/24 cogs, an Enviolo Heavy Duty gear hub, and a Gates belt drive. There are three issues: The user complains about having to pedal too hard up hill, even though someone she knows with the same bike — ie. same...

    Enviolo shifter tips or tricks?

    Just like for Shimano gear hubs, the "Enviolo cable tool" isn't required but nice to have. How to set the cable length for the manual hub interface (with the enviolo cable tool)

    [Bafang + Nuvinci] Cargo bike seizes up in hills

    Ah, didn't think of the controller. Thanks much for the input. She never could resume cycling, even after turning the motor off and on. But we'll never know for that Dutch-made trike, as she finally got the LBS to replace it with a two-wheel Bakfiets, also with a Bafang mid-drive. Too bad no...

    [Bafang + Nuvinci] Cargo bike seizes up in hills

    Hello, Remotely, I'm trying to help a non-techie who bought a Dutch-made used cargo trike in good condition from a bike shop. 1. It has a Bafang M400 mid-drive (MM G33.250, 36V 250W 14A; It's in Europe, hence the 250W motor)), and a Nuvinci Optimized 330 gear hub with an automatic shifter + H3...

    Enviolo NuVinci CVP Hub Overview

    Thanks. I was more concerned about the internals, since like all gear hubs save the Shimano Nexus 5, the Enviolo predates mid-drive motors, and some users can be a bit rough.

    How reliable is the Enviolo with a mid-drive motor on a cargo bike, ie. a much heavier bike than a regular e-bike?

    Why are bottom brackets with torque sensor so rare?

    Thanks, I did know about the TSDZ2 middrive, but replacing the controller looks like a much easier and cheaper alternative for that existing bike — after bottom brackets with a torque sensor… which seem unvailable for a Bafang rear hub. What plug and play KT controller do you guys suggest for...

    Why are bottom brackets with torque sensor so rare?

    Throttles are illegal in Europe. Still, how would I add it to that rear hub Bafang-powered bike? Would I need a new controller? Also, what does "power based" cadence system (KT's "torque simulation") really does/mean?

    Why are bottom brackets with torque sensor so rare?

    Thanks for the infos. I'm looking for a financially reasonable solution to add to that rear hub Bafang bike shown in the picture. Since it's in Europe, it has no throttle (illegal.) Does Grin Tech provide a bottom bracket with torque sensor that I could hook up to a Bafang hub motor...

    Why are bottom brackets with torque sensor so rare?

    Hello, I know someone who bought a second-hand e-bike with a Bafang/8 fun rear hub motor, and is looking for a solution to replace the very unnatural on/off cadence sensor. It feels like riding a motorcycle. So I looked for Bafang-compatible bottom brackets with torque sensor… and found none...
