Thank you so much for that formula! (hub+rim+spokes etc.) I think your breakdown of why the shop doesn't want to help game that out sounds dead accurate. If I were them, I'd be thinking about it the same way. Your point about maintenance for lighter rims is well taken, too. I do have a good...

Ah, I see. Do all Americans have the same values? Come on, Stefan. You're better than that. You know better than that. What I said was: I don't lecture them about how many people they are going to kill or how dangerous it is. How did you get from there to 'remain silent'? There are...

Stefan, I've known you to be pretty harsh before, but accusing other board members of being murderers is a new low for you. This is aggressive behavior. I don't know who I'd be more worried about sharing the road with right now-- the OP or with you! You also know I'm a health care provider...

These are great points, as is Blackhand's response, which brings me to something I haven't mentioned: I love the way this bike handles and corners. That's an argument for going slow with changes to the weight high on the frame. The bars are a worthy gamble-- if I hate them, I've only gambled...

Yeah, that may be for the tires, but I do have to replace them in the fall, and if I can find something that rolls a little faster and is a little lighter, why not? I'm not even sure I can find Maxxis Ikons in 2.1 anymore. As for wheels, I'm trying to get a fix on how much my current wheels...

No. There are so many things wrong with that analogy, I wouldn't know where to start. If I'm working with someone who drinks and drives, I don't lecture them about how many people they are going to kill or how dangerous it is. That approach is doomed to fail. There is a playbook for how to...

As many of you know, I ride an XCish 46ish pound Class 1 FS eMTB with a 250 watt 40 nm motor and 34mm Suntour middle-of-the-road front fork. I break 30 MPH fairly frequently and occasionally break 40 MPH, but do that only very briefly on pavement that is smooth. On the trail I'm usually on...

Stefan! I'm not sure this is the right approachl if you actually want to convince him to slow / power down. However... This. Can we find out more about the bike? Its weight, your weight, how wide your tires are, if it's a 29er or 27.5, what kind of terrain you ride on-- how steep it is...

Past tense, I no longer have this motor, but it was really a mix. On flat terrain, I rode without any power, but while climbing, I had a trigger throttle that provided variable assist/ However, it was a low power motor, so there were not many increments to the amount of assist! I would say...

All very interesting. Early versions of the Marin Team 1 sometimes experienced broken seat stays, though everyone seems to love Marin and says they are super reliable. They repaired the broken frames at no charge and redesigned the frame / welds at least twice before my version, but I trolled...

Just those two things, particularly the long, steep climbs, but it's a fair question because I don't KNOW that for sure. It's just an educated guess. Everyone told me, 'hub motors aren't designed for steep climbs!' but I ignored them, and it seemed to be fine... until it wasn't. I sometimes...

The other issue that factors into the equation is the grades that you ride and how powerful your motor is. I ride at 50 PSI on 2.1s that are designed for 60 max because the hills here are so steep and my motor is so weak. If I rode somewhere more normal, I'd probably run them at 38 or low 40s...

My gut is telling me: Don't do this. The thing about CF-- as I understand it-- is that it's extremely lightweight and durable and very safe when subjected to stress from the vectors it was designed for. At its simplest level, this is why CF works for airplane hulls and not for submersibles, or...

This is totally awesome, 6z. What's the worst that could happen, or is this unknown? If the worst is it not working, I would totally try that. If the worst is bricking the controller or battery, that's more problematic. If the worst is blowing up the batteries, and dying pointlessly in an...

Yeah, I lost your outstanding thread/tutorial here (I think it was you?!) about using tool batteries as range extenders. I would really like to set that up for the Shimano 6010 battery. I have one mega-ride planned -- basically, riding from my house to the eastern edge of the Verdugos, riding...

Funny this topic came up just at this moment. With a bike and battery I bought in March of 2021, tariffs happening, social security and retirement funds at greater risk, I was wondering: Should I get a new battery? Even if it cost me $500 now, that price could be $800 or more in a couple of...

My bike is 46.5 pounds-- sort of an "L" instead of an "SL"-- and I'm fascinated at how minor increases in grade makes a difference in terms of whether, and how long, I can ride without assistance. On dead flat terrain, I set assistance to zero, and it's hardly any different from ECO, I ride for...

It probably depends on where you are riding, but I found that the extra (real world ) 6 MPH on my bike with a TSDZ2B made for safer riding in traffic on narrow streets with two lanes and a traffic speeds of 30-40 MPH, or it sure felt that way. Riding to the bank, I'd be passed by three cars vs...

Interesting. I don't know if there is a bright-line answer to this question, but... I ride 80% broken, cracked and crumbling pavement and 20% dirt; the thing is, when I want to ride dirt, I really want to ride dirt. I'm running 2.2 Maxxis Ikons at 50 PSI (they are 60 PSI max, so that should...

These sound really awesome! I'll see if you like them as much in a few months, and then probably take the plunge! I don't... quite understand Stefan's issue with complaints about Presta. And of course I ride Presta; I go tubeless on almost everything, and I've been riding Presta / Tubeless...
